 SUMMARY OF CHANGES INCORPORATED INTO A318/A319/A320/A321 MRB REPORT 

REVISION 18 

GENERAL

The MRB Report Rev 18 is issued in order to reflect: 

- Requirements for aircraft fitted with Sharklets 

- Amended requirements following aircraft modifications 

- Task interval optimizations 

- Minor amendments and improvements 

NOTE: SoC from previous MRBR revisions are not published with this MRBR. SoC for previous MRBR 

revisions could be found with the related revision or Airbus can be contacted for this. 

To enable the task revision status to be identified, during document revision, a movement code (N = New 

task, R = Revised task, D = Deleted task), is printed in the margin opposite each task affected by the revision. 

This movement code is set by comparing the new revision of the document with the previous approved 

revision of the report. 

ALL SECTIONS

From MRBR Rev 18, no date will be printed on the pages anymore; only the Revision Number is given. 

The month and year of document approval is now shown on the cover page and on the “Record of Revisions” 

page.

SECTION A

INTRODUCTION

1. SCOPE AND PURPOSE

This report outlines the initial minimum scheduled maintenance/inspection requirements to be used 

in the development of an approved continuous airworthiness maintenance program for the airframe, 

engines, systems, and components of the AIRBUS A318, A319, A320 and A321 aircraft. These MRB 

requirements are a basis from which each air carrier develops its own continuous airworthiness 

maintenance program. 

This document is referenced in the Type Certificate Data Sheet (TCDS) under the number A.064. 

The tasks and their intervals given in this Report, together with the Certification Maintenance 

Requirements and Airworthiness Limitations, form part of the instructions considered essential for 

proper maintenance as required by certification requirements for JAR/FAR 25.1529 and JAR/FAR 

25. Appendix H, Instructions for Continued Airworthiness. 

This Report has been approved by the following authorities and is proposed to other Authorities for 

their endorsement: 

 - European Aviation Safety Agency (EASA) 

 - FAA (With the addition of Section F, Requirements for U.S. Operators) 

 - Transport Canada 

The information and instructions included herein are applicable to the following A318, A319, A320 

and A321 models and powerplants as defined on the aircraft Type Certificate Data Sheet: 

-A318-110 with CFM56-5B powerplant 

-A318-120 with PW6000A powerplant 

-A319-110 with CFM56-5 powerplant 

-A319-130 with IAE V2500 powerplant

2. BASIS FOR STANDARDS AND PROCEDURES

The scheduled maintenance tasks and intervals contained in this Report have been developed in 

accordance with MSG-3 and fully detailed in the A318/A319/A320/A321 Maintenance Program 

Development Policy and Procedures Handbook - Reference ST5/569/86. For details of the 

associated working bodies see Appendix 3 of this Report.

This MRB Report for the A318/A319/A320/A321 is suitable for an aircraft average utilization of 

between 1800 FH and 4400 FH and between 1000 FC and 2500 FC within a 12 months period. 

Operators whose aircraft utilization differs significantly from these parameters may be required to 

make adjustments to their program with their Regulatory Authority.

3. REVISION POLICY

This MRB Report has been regularly revised for various reasons like introduction of new aircraft 

models, completion of the fatigue test and teardown analysis and maintenance tasks evolutions. In 

addition, the need for revision will be considered on an annual basis following discussion between the 

ISC Chairman, the ISC Co-chairman and the MRB Chairmen. An ISC meeting will be called if the 

revision is significant. Minor changes will be handled by postal correspondence with ISC/MRB 

members.

4. OVERALL DOCUMENT DESCRIPTION

The maintenance tasks and their intervals are presented in the Systems and Powerplant, Structures 

and Zonal sections.

The Systems and Powerplant section defines specific tasks at the level of each Maintenance 

Significant Item (MSI) considering the failure effects and failure causes.

The Structures section defines the necessary inspections for each Structural Significant Item (SSI) 

developed through evaluation with respect to environmental and ageing deterioration, accidental and 

fatigue damage. Fatigue damage inspections, which are Airworthiness Limitation Items (ALI) are not 

contained in this MRBR but in the dedicated ALI document. 

Corrosion Prevention and Control Program (CPCP) tasks are contained in the Structures section;

CPCP requirements covered by the ZIP are identified in Appendix 9.

General Visual Inspection (GVI) that are covered by ZIP tasks are not contained in the Systems or 

Structures Sections (Section C or D) but provided in Appendix 9 for reference.

The Zonal section defines General Visual Inspections of systems installations, EWIS and structure by 

aircraft zone.

Post certification, the Type Certification authorities requested Airbus to ensure that the Lightning / 

High Intensity Radiated Fields (HIRF) protection of critical systems installed in the A320 is adequately 

addressed in the operator’s maintenance program. The manufacturer identified an appropriate 

method by which to confirm that in-service operation will not reduce this protection to a level that is 

inadequate to maintain Type Certification objectives. This is explained in Appendix 7.
 A318/A319/A320/A321 MRB REPORT

Rev 18 Page: A3

5. INSPECTION INTERVALS

SYSTEMS SECTION

All task intervals are expressed in terms of usage parameters, i.e. FH, FC or calendar time (years, 

months, days). The most appropriate interval has been selected for every task. Intervals are going to 

be further optimized using in-service feedback and manufacturer experience.

STRUCTURES SECTION

For the Structures section the basic thresholds and intervals for environmental deterioration related 

items are as follows:

- Threshold 6 Years and 12 Years

- Interval 6 Years and 12 Years.

Thresholds and intervals for fatigue damage related items are given in Flight Cycles (and Flight 

Hours for range sensitive items).

ZONAL SECTION

For Zonal tasks the basic intervals are 4 months and multiples, 24 months and 48 months, 6 Years 

and 12 Years. 

Credit may be taken from previous A318, A319, A320 or A321 operational experience.

The MRB Report is not intended to give the total maintenance program. There are items which are 

typically performed by each operator more frequent than 750 FH / 750 FC / 4 MO. The routine 

content of checks occurring more frequent than the 750 FH / 750 FC / 4 MO shall be developed by 

the operator and approved/accepted by their local Regulatory Authority. Maintenance/inspection 

tasks with intervals more frequent than 750 FH / 750 FC / 4 MO found in this MRB Report were 

developed through the MSG-3 analysis process.
 A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: B1

SECTION B

GENERAL RULES 

1. The operator's manuals shall contain the details and responsibilities for accomplishing the 

maintenance defined in this MRB Report. 

2. The overall reliability of the aircraft will be monitored by each operator's system for continuous 

analysis and surveillance as required by the operator's Regulatory Authority. 

3. Task intervals may be changed in accordance with the Operator's Regulatory Authority practices 

and rules. In this respect attention is drawn to the following: 

- for Systems and Powerplant tasks, to the Failure Effect Category (FEC) noted in Section C, 

Systems and Powerplant 

- for Structures tasks, to tasks derived from Damage Tolerance evaluation as noted in Section 

D, Structures 

- for Zonal tasks, to the validity of the General Visual Inspections transferred from Structures or 

Systems and Powerplant. 

- for ATA chapter 20 not to delete tasks with the identifier “EWIS”

In addition, CMRs, mandatory structural inspections and life limits are to be handled with specific 

associated rules, as described in Rules 5, 6 and 7 below. 

4. Each operator should be aware of the various inspection techniques such as X-Ray, ultrasonic, 

eddy current, radioisotope, ... which are available and described in the Non-Destructive Testing 

Manual (NTM). 

5. Items that are life limited will be discarded according to the life limits stated in the appropriate 

section of the engine or aircraft manufacturer's manuals. These sections are referenced in the 

aircraft's Type Certificate Data Sheet.

6. Certification Maintenance Requirement tasks/intervals arising from analyses (e.g. System Safety 

Assessments) performed as part of the Type Certification process are given in AIRBUS document 

ALS Part 3 - Certification Maintenance Requirements (CMR). Appendix 1 of this MRB Report 

indicates where this document is located. The process by which CMRs are identified is independent 

of the MSG-3 analysis process. The ALS Part 3 document is the controlling document for all tasks 

identified as CMRs. When the interval for a MRB task is less (more restrictive) than the applicable 

CMR task interval, the MRB Report interval will take precedence. Conversely, where the CMR 

interval for an MRB Report task is more restrictive, the CMR interval takes precedence. 

7. Mandatory structural inspection thresholds and intervals resulting from damage tolerance 

evaluation are given in the AIRBUS document ALS Part 2 - Damage-Tolerant Airworthiness 

Limitation Items (DT ALI). Appendix 1 of this MRB Report indicates where this document is located. 

The ALS Part 2 document is the controlling document for all tasks identified as DT ALI. 

8. Within the MRB Report the terms "test", "check" and "inspection" are not intended to imply a level 

of skill required to accomplish the task. 
 A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: B2

9. Tasks may be considered to conform to the requirements of the scheduled maintenance program 

if accomplished as part of an equivalent check/test performed by the operators flight crew in 

accordance with an approved/accepted flight crew normal check list and with Regulatory Authority 

concurrence. 

10. It is the responsibility of each operator to adjust their own maintenance program in accordance with 

their National Requirements, and to comply with existing rules with respect to reporting to their 

Regulatory Authority and to the manufacturer, events having effects on the continued airworthiness 

of the aircraft. 

11. The reapplication of all protective materials (e.g. corrosion inhibiting compounds, paints, etc.) shall 

be carried out following their removal to perform the inspection/maintenance task. 

12. For Maintenance Standards applicable to ETOPS operators should refer to the relevant AIRBUS 

A318/A319/A320/A321 ETOPS CMP Document. 

13. Task interval parameters expressed in the MRB Report may be converted to an individual 

operator's desired unit (flight hours, cycles or calendar time) provided this conversion does not 

result in the operator exceeding the initial requirements of the MRB Report. 

14. Any fairings, panels, doors or other items which are removed/opened to gain access for 

maintenance tasks must also be inspected for general condition with a minimum level of GVI 

before reassembly/refitting.

15. Tasks approved from Fuel Tank Safety (FTS) Requirements using the criteria established in 

Special Federal Aviation Regulation (SFAR88)/EASA policy statement on the process for 

developing instructions for maintenance and inspections of fuel tank system ignition source 

prevention; are identified: for example (SFAR 88) in parenthesis following the task description in the 

MRB Report. 

For Operators under U.S. FAA Jurisdiction only: 

Operators requesting revisions to the baseline FTS requirements for failure effect category (FEC) 5 

and 8 tasks, description or intervals, must submit their request through the cognizant Flight 

Standards District Office, who may add comments and then forward it to the manager of the 

appropriate FAA Aircraft Certification Office, or office of the Transport Airplane Directorate, having 

cognizance over the type certificate for the affected airplane for concurrence prior to approval. 

Tasks and intervals other than FEC 5 and 8 may be revised through normal operator approval 

process. 

For Operators not under U.S. FAA Jurisdiction: 

Operators requesting revisions to the baseline FTS requirements may revise these tasks and 

intervals through their normal operator approval process. 

16. Electrical Wiring Interconnection System (EWIS) derived from the Enhanced Zonal Analysis 

Procedure (EZAP), standard zonal tasks included, are identified by “(EWIS)” in parenthesis 

following the task description in the MRB Report. 

For Operators under U.S. FAA Jurisdiction only: 

Operators requesting revisions to the baseline EWIS task or description must submit their request 

through the cognizant Flight Standards District Office, who may add comments and then forward it 

to the manager of the appropriate FAA Aircraft Certification Office, or office of the Transport 

Airplane Directorate, having cognizance over the type certificate for the affected airplane for

SECTION C

SYSTEMS AND POWER PLANT 

1. GENERAL

This section provides the initial minimum scheduled maintenance tasks and intervals for all systems 

including power plants and auxiliary power unit. 

With respect to the evaluation procedures and the resulting tasks the following is noted: 

(a) The A320 Systems and Powerplant section was developed using MSG-3 Revision 0. The 

A321 Systems and Powerplant section was developed using MSG-3 Revision 1. The A318 

and A319 Systems and Powerplant section has been developed using MSG-3 Revision 2. 

(b) The term "Visual Check" was introduced with MSG-3 Rev.1. This terminology has been 

retrospectively applied to identify A320 failure finding tasks, which had been identified as 

general visual inspections. 

(c) MSG-3 analysis allocates tasks against the following Failure Effect Categories (FEC) 

depending on the consequence of failure: 

- FEC 5 : Evident Safety Effects 

- FEC 6 : Evident Economic (Operational) Effects (Rev.0) 

- FEC 6 : Evident Operational Effects (Rev.1, Rev. 2)

- FEC 7 : Evident Economic (Non-Operational) Effects (Rev.0) 

- FEC 7 : Evident Economic Effects (Rev.1, Rev. 2) 

- FEC 8 : Hidden Function Safety Effects 

- FEC 9 : Hidden Function Non-Safety Effects 

The FECs are given in this section against each task for information. 

The notation “-“ (hyphen) in the FEC column indicates that the task has not been developed 

through the MSG-3 systems and power plant logic. 

(d) DELETED with MRBR Issue June 2004 

 

(e) Shop maintenance tasks ("off-wing") are not mentioned in the APU and Power Plant Chapters. 

Operators should take the opportunity of engine removals and disassemblies to perform offwing inspections and parts/assemblies restoration, as per engine shop manuals. 

No scheduled basis for these tasks is defined in this MRB Report. 

(f) No threshold or opportunity inspection requirements are given for APU or Power Plant. 

Manufacturers may recommend such inspections in the event that late development or early 

in-service experience would indicate the desirability to examine specific components of 

individual engines. If this is necessary, then direct negotiations between applicable operators 

and the engine manufacturer will be arranged. Results of these inspections are to be made 

available by the manufacturers to other customer airlines as well as the regulatory authorities. 
A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: C2 

(g) As noted in General Rules, Section B, limitations of life limited parts are controlled by the 

manufacturers and published in the following documents: 

 - Airbus A318/A319/A320/A321 Airworthiness Limitation Section Part 1 

 - CFM 56-5 Engine Shop Manual Chapter 5 

 - IAE V2500 Engine Manual Chapter 5 

 - Garrett GTCP 36-300 Engine Component Maintenance Manual 

 - APIC APS 3200 Component Maintenance Manual 

 - Allied Signal 131-9(A) Engine Manual 

(h) Scheduled maintenance tasks derived from MSG-3 analysis and subsequently identified as fully 

covered by zonal task(s) are listed, by ATA Chapter, in Appendix 9 for reference. 

(j) DELETED with MRBR Issue March 1999 

(k) Category II/III landing capabilities and RVSM capability are inherent functions of the basic design 

standard of the aircraft. Scheduled tasks necessary for these operations have been considered in 

the development of this section. Operators should comply with National Requirements as applicable. 

(l) DELETED with MRBR Issue December 2010 

 

(m) When more than one interval figure is assigned to a task, and when not stated otherwise, the interval 

expiring first shall apply. 

(n) Tasks arising from the Enhanced Zonal Analysis Procedure (EZAP), (comprised of GVI tasks not 

fully covered by Zonal tasks and DI/RS tasks) are included within ATA chapter 20 of the System and 

Powerplant section of the MRBR and have no Failure Effect Category (FEC) quoted. The tasks are 

identified with “(EWIS)” following the task description (see Section B General rule 16 for further 

details). 

 These tasks remain under the responsibility of the Zonal Maintenance Working Group. 

 Note *: ATA 20 tasks must not be deleted from the operators maintenance program 

(o) During a review of an aircraft system for the purpose of modifying or verifying the maintenance 

requirements, the reviewer must be aware that those functions associated with the ignition 

prevention features of all systems are identified and analysed in MSI 28-18-00 Ignition Prevention. 

The tasks are identified with “(SFAR88)” following the task description (see Section B General Rule 

15. for further details). 

 Any review of an existing MSI task must therefore consider that it may be necessary to review MSI 

28-18-00 in addition to the specific system MSI identified 

2. ZONAL TASK COMPATIBILITY

When General Visual Inspection (GVI) level has been selected for a particular MSI task, the inspection 

requirement can be considered adequately covered by a Zonal task if it meets certain criteria. 

The following criteria have been considered as prerequisite for GVI coverage by Zonal: 

- The access requirements are compatible. 

- The equivalent ZIP task is performed as frequently, or, more frequently than the inspection interval 

quoted in this section. Because all intervals in this section are quoted in the appropriate usage 

parameter(s), the maximum aircraft utilization as given in SECTION A para 2 must be considered. 

Applying the MRBR envelope, a significant number of tasks would not fulfil the transfer criteria 

regarding task frequency and would become stand-alone tasks. To avoid this, a secondary 

parameter is given to those ZIP tasks which are able to cover one or more MSI tasks. See Section 

E, para 2 for more information regarding the quotation of ZIP intervals. 

- No FEC 5 or FEC 8 GVI tasks must be transferred to ZIP. 

If the above criteria are met, the GVI tasks are not listed in Section C but are referenced in Appendix 9. 

NOTE: The task number of transferred tasks that were listed in MRBR Rev. 15 is kept in Section C for 

traceability reasons. GVIs identified in MSG-3 analyses after MRBR Rev. 15 are only referenced in

TASK MSI AND TASK DESCRIPTION FEC INTERVAL APPLICABILITY

1 2 3 4 5 6

1- This column indicates the MSI reference number and is directly obtained from the Airbus ATA Breakdown and Nomenclature Reference document. 

Paragraph C1(l) identifies MSIs that address two or more systems / sub-systems. For tasks arising from the Enhanced Zonal Analysis Procedure (EZAP) 

the reference number includes the first zone number of the source MSG-3 analysis (e.g. 20.0.151 is for aft cargo compartment – zones 151/152). 

2- This column identifies the task and thus enables the user to understand from which MSG-3 Level 2 logic question the task has been developed, i.e.: 

- LUB Lubrication 5A, 6A, 7A, 8A, 9A 

- SVC Servicing 5A, 6A, 7A, 8A, 9A 

- OPC Operational Check 8B, 9B 

- VCK Visual Check 8B, 9B 

- GVI, DET, SDI Inspection 5B, 6B, 7B, 8C, 9C

- FNC Functional Check 5B, 6B, 7B, 8C, 9C 

- RST Restoration 5C, 6C, 7C, 8D, 9D 

- DIS Discard 5D, 6D, 7D, 8E, 9E 

This information can be used to clarify whether the task is to detect a failure (8B, 9B) or to detect degradation (5B, 6B, 7B, 8C, 9C). 

3- This column identifies the MSI title (which is in accordance with the Airbus ATA Breakdown) and the description of each task identified through the MRB 

Report development process. 

 The term "No task selected" indicates that the MSI has been subjected to a full MSG-3 analysis but no applicable and effective tasks have been 

identified. 

 The term "-task deleted-" indicates that during the development process a task had been proposed which was eventually deleted due to re analysis, task 

amalgamation or ISC decision. Renumbering of tasks has been avoided in order to minimise impact on cross-reference data in operators initial 

maintenance schedules.
A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: C7

4- This column identifies the Failure Effect Category (FEC). MSG-3 analysis allocates tasks against the following FECs depending on the consequence of 

failure: 

- FEC 5: Evident Safety Effects 

- FEC 6: Evident Operational Effects 

- FEC 7: Evident Economic Effects 

- FEC 8: Hidden Safety Effects 

- FEC 9: Hidden Non-Safety Effects 

 

 The notation "-" (hyphen) in the FEC column indicates that the task has either not been developed through the MSG-3 logic process (such tasks arise 

from either a specific MRB requirement (e.g. escape slide sampling) or have been determined as necessary to maintain compliance with Type 

Certification requirements) or that task was developed within the EZAP process. 

 Multiple FECs are quoted only when the task is associated with both a hidden and an evident FEC. Where multiple hidden FECs (8, 9) or multiple evident 

FECs (5, 6, 7) are applicable only the most important one is quoted. 

5- This column identifies the interval between successive accomplishments of the task. 

 The "NOTE..." referred to in this column is detailed in Section C para 3. "SECTION C related NOTES".

Rev 18 Page: D1

SECTION D

STRUCTURES 

1. INTRODUCTION

This section provides the basic scheduled maintenance tasks and frequencies applicable to the 

aircraft structure. 

The purpose of this section is to maintain the continuous airworthiness of the aircraft structure and 

to control corrosion to Level 1 or better (ref: 7. CORROSION PREVENTION AND CONTROL 

PROGRAM for definition of Level 1 corrosion). 

2. INSPECTION PHILOSOPHY

This section has been developed by considering the following sources of damage: 

 2.1 Metallics

 

- Fatigue Damage (FD) 

 - Environmental Deterioration (ED)

 - Accidental Damage (AD) 

 Fatigue Damage

 For FD, the damage initiation and subsequent damage growth is primarily dependent on 

the ground-air-ground loading variation, which occurs once per flight. Therefore, flight 

cycles (FC) are used as the unit for thresholds and repeat intervals. Some fatigue related 

SSIs are also sensitive to flight duration. For these SSIs, a FH limit is stated in addition to 

the FC limit. The inspection is to be performed at whichever limit is reached first. 

 The structure inspection tasks selected for fatigue are derived from damage 

toleranceaevaluation according to the criteria defined by FAR/JAR 25.571, Amendment 45, 

with the aim of ensuring timely damage detection. The FC and FH data is based on a 

combination of calculation, full-scale fatigue test teardown results, and in-service 

experience (where available). 

 Environmental Deterioration 

 For ED, since the deterioration caused by the environment (e.g. corrosion, stress 

corrosion) is mainly time dependant, inspection intervals and thresholds are based on 

calendar time (Years). 

 Accidental Damage

For deterioration caused by accidental damage, it is considered that major damage such as 

that caused by bird impact, or ground handling equipment, will be detected by routine 

inspections. AD consists of minor damage which could result in fatigue and/or corrosion 

damage, and which could propagate undetected. In the analysis, the fatigue and 

environmental effects of the accidental damage are considered. A dedicated AD task is not 

selected; the AD requirement is consolidated into either the ED or the FD task, or both, 

according to the AD consequences. AD is therefore subject to maintenance requirements 

expressed in FC (and FH) or calendar time or both. 

2.2 Non-metallics

 - Ageing Deterioration 

 - Accidental Damage 
A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: D2

 Ageing Deterioration

Deterioration caused by ageing considers loading conditions and environmental 

conditions. Inspection intervals and thresholds are based on calendar time. 

 Accidental Damage

 Deterioration caused by accidental damage is subject to inspection intervals based on 

calendar time. 

 The frequency of inspection is dependant on static strength reduction caused by the 

selected damage, combined with the likelihood of the selected damage occurring more 

than once during the basic interval. 

As this kind of deterioration is random in nature, inspections shall be applied to all 

aircraft at each repeat interval without threshold. 

3. INSPECTION LEVELS

According to the analysis procedure, for each Structural Significant Item (SSI), various inspection 

levels have been considered with the aim of selecting the lowest inspection level compatible with 

the type of damage and the expected damage growth. Therefore, one or more of the following 

inspection levels have been selected for each SSI: 

General Visual Inspection (GVI) 

Detailed Inspection (DET) 

Special Detailed Inspection (SDI) 

 For definition of inspection levels refer to GLOSSARY, Appendix 4. 

4. ZONAL TASK (ZIP) COMPATIBILITY

When General Visual Inspection (GVI) level has been selected for a particular SSI, the inspection 

requirement may be considered adequately covered by Zonal tasks which are then referenced in 

Appendix 9. 

The following criteria have been considered as prerequisite for GVI coverage by Zonal: 

- The access requirements are compatible. 

- The equivalent ZIP task is performed as frequently, or, more frequently than the inspection 

threshold and interval quoted in this section. 

- The maximum compatible interval is calculated by taking the upper limit of the aircraft average 

utilization as given in Section A, para 2.

- For ZIP Tasks of 4 MO, the equivalent structures task interval must be equal to or greater than 

1500 FH / 850 FC. 

- For ZIP tasks of 24 months, the equivalent structures task interval must be equal to or greater 

than a nominal value of 5000 FC / 8800 FH. 

- For ZIP Tasks of 6 Yrs, the equivalent structures task interval must be equal to or greater than 

15000 FC / 26400 FH. 

The maintenance programs of individual operators which deviate from the requirements given in 

this report (e.g. interval frame, utilisation) will need to be rechecked to ensure Zonal task 

compatibility. 

All structure not selected as Structural Significant Item (SSI) is classified as „Other Structure‟ 

(Refer to GLOSSARY, Appendix 4), and is covered by Zonal tasks as provided in Section E. 
A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: D3

GVI SSIs which also require the application of Temporary Protection Systems (TPS) shall not be 

covered by Zonal tasks. 

ALI requirements are not given in Section D of this document. The operator must consider the 

latest issue of the ALI document (ALS Part 2) for applicable requirements. 

5. INSPECTION CATEGORIES

5.1 INTRODUCTION

 Structure inspections fall into the following three categories: 

- 100% Tasks with no associated Sampling Task 

- Sampling Tasks with no associated 100% Task 

- Sampling Tasks that become 100% for the non sampling aircraft at the 100% 

Threshold. 

The inspections performed on sampling fleet aircraft prevent performing the sampling 

inspections on 100% of one operator‟s fleet at the listed sampling threshold as per task. 

In case an operator does not define a sampling fleet, it is the Airbus recommendation to 

perform applicable sampling inspection requirements on all aircraft of the operator‟s fleet. 

5.2 100% TASKS WITH NO ASSOCIATED SAMPLING TASK

 

 These are: 

 Fatigue tasks where calculation and/or test indicate a high fatigue sensitivity which are 

however, not classified as ALI. These tasks are not selected for Sampling. These tasks 

have a 100% Threshold only e.g. 551002-01-2. 

 Fatigue and Environmental Deterioration (corrosion or ageing) tasks where Accidental 

Damage is likely. These tasks are not selected for Sampling. These tasks have a 

100% Threshold only e.g. 534135-01-4. 

100% tasks are indicated by an entry in the “100% THRESHOLD INTERVAL” column only and 

must be performed on all aircraft of the fleet, regardless their sample status. 

5.3 SAMPLING TASKS THAT BECOME 100%

These are:

 Fatigue tasks where calculation and/or test indicate a medium fatigue sensitivity. 

These tasks are selected for sampling. These tasks have a Sampling Threshold and a 

100% Threshold. In most cases, those tasks become an ALI requirement when 

reaching the 100% threshold and must be inspected according to the values and 

applicabilities as given in the ALI document e.g. 534137-01-1. 

 Corrosion tasks where in-service experience indicates that damage is not likely are 

selected for sampling. These tasks have a Sampling Threshold and a 100% Threshold. 

All aircraft not inspected as sampling aircraft must be inspected at the 100% Threshold 

e.g. 574304-01-1.

 

Sampling tasks that become 100% are indicated by an entry in the “SAMPLING THRESHOLD 

INTERVAL” and an entry in the “100% THRESHOLD INTERVAL” column. 

For the selected Sampling Program aircraft, inspections commence at the Sampling Threshold 

or at the 100% Threshold whatever comes first. Repetitive inspections have to be performed 

at every Sampling Interval or 100% Interval whatever comes first (counting from the date / FH 

/ FC of the threshold / previous inspection). 
A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: D4

On aircraft not selected for the Sampling Program, the 100% Threshold is the first time when a 

task has to be performed. 

 

 

NOTE: The inspection is not required to be repeated when a sampling fleet aircraft reaches 

the 100% threshold and a sampling requirement of the task was already performed on this 

aircraft. Compliance to the 100% inspection requirement is shown with the accomplishment of 

sampling task inspections for the sampling threshold and follow up intervals. This statement is 

valid for utilisation (FC / FH) – and calendar time (YE) based inspection requirements. 

NOTE: For several MRBR tasks, an additional ALI requirement exists. Operators need to 

check the latest ALS Part 2 document for applicable requirements. 

5.4 SAMPLING TASKS WITHOUT A 100% REQUIREMENT 

 

These are: 

Fatigue tasks where calculation and/or test indicate a low fatigue sensitivity. These items 

are selected for sampling e.g. 531120-01-1. FD sampling threshold inspections without a 

100% inspection requirement typically start at or after 30000 FC, depending on the fatigue 

sensitivity of the item to be inspected.

NOTE: Some FD sampling items show a threshold equal to the applicable aircraft 

utilization limit for A320FAM aircraft types as per chapter 8 GENERAL RULES 

APPLICABLE TO THE STRUCTURE SECTION. 

These tasks are subject for review during A320FAM Service Goal extension exercises. 

Sampling Tasks are indicated by an entry in the “SAMPLING THRESHOLD INTERVAL” 

column only e.g. 531120-01-1. These tasks need only to be performed on aircraft selected as 

sampling aircraft. 

NOTE: For several MRBR tasks, an additional ALI requirement exists. Operators need to 

check the latest ALS Part 2 document for applicable requirements.

6. SAMPLING PROGRAM

6.1 INTRODUCTION

The purpose of the Sampling Program is to detect systematic deterioration caused by the 

environment and/or fatigue, on a group of aircraft selected from those which have the highest 

age within a considered fleet. The Sampling Program is applicable to both Environmental 

Deterioration (ED) and Fatigue Damage (FD) SSIs, where the deterioration, should it occur, is 

considered as being progressive with age or operating usage. Only those SSIs for which a 

systematic environmental deterioration/fatigue damage characteristic has been analysed will 

be considered for inclusion in the Sampling Program. 

SSIs which are susceptible to Accidental Damage (AD) [Non-systematic] are not considered 

for the Sampling Program. 

Sampling Program inspections are to monitor utilisation and environmental circumstances of 

one operator. The 100% threshold of a sampling task provides information about the 

inspection point for aircraft that are not part of the sampling fleet. 

All aircraft being part of the sampling fleet are continuously inspected in advance of the rest of 

the fleet at the sampling inspection threshold and afterwards following the sampling interval 

inspection requirement. 

Example 1: 

Sampling inspection requirement with 100% threshold (CPCP) 

Task 535151-01-1: 

- Sampling threshold 12 YE; sampling interval 12 YE; 

- 100% threshold 24 YE, 100 % interval 12 YE 

Sampling fleet aircraft inspection dates: 

First inspection at 12 YE, repetitive inspection 12 YE after first inspection performed (24 YE, 

36 YE...)

Non sampling fleet aircraft (sampling fleet installed): 

First inspection at 24 YE, repetitive inspection 12 YE after first inspection performed (36 YE, 

48 YE...) 

Example 2: 

Sampling inspection requirement with 100% threshold (FD) 

Task 572004-01-4: 

- Sampling threshold 30000 FC OR 49700 FH; sampling interval 14700 FC OR 24300 FH 

(MRBR); 

- 100% threshold 39800 FC OR 60000 FH, 100% interval 14700 FC OR 24300 FH (ALS Part 

2 / ALI item) 

Sampling fleet aircraft inspection dates: 

First inspection at 30000 FC OR 49700 FH , repetitive inspection every 14700 FC OR 24300 

FH after first inspection performed(whatever comes first). 

Non sampling fleet aircraft (sampling fleet installed): 

First inspection at 39800 FC OR 60000 FH, repetitive inspection every every 14700 FC OR 

24300 FH after first inspection performed (whatever comes first). 

 Based on the results of Sampling Program inspections the following applies: 

- In case of findings each operator should take appropriate corrective actions, such as 

change of program concept, decrease in interval, application of TPS etc. 

In case of no finding, the current inspections continue to apply. 
A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: D6

6.2 SELECTION OF AIRCRAFT FOR SAMPLING PROGRAM

For Sampling Program, a number of aircraft have to be determined as sampling aircraft, at the 

level of each operator. 

For each operator, the Sampling Program aircraft will be the oldest 1/5 aircraft, in the 

operator‟s fleet, in years. 

 The oldest aircraft are defined as the aircraft with the highest age in years since their initial 

 manufacturer‟s delivery date. 

 NOTE: For operators with more than one aircraft type in their fleet, e.g. A318, A319, A320 

and A321, the Sampling Program aircraft have to be determined per aircraft type, e.g. 1/5 of 

the oldest A318 aircraft, 1/5 of the oldest A319 aircraft + 1/5 of the oldest A320 aircraft + 1/5 of 

the oldest A321 aircraft. 

If the number of aircraft selected is not a whole number, the number can be decreased to the 

next lower whole number. The minimum sample size is one aircraft per aircraft type. The 

maximum number of aircraft to be sampled is 5 aircraft per aircraft type even if the total fleet 

size would lead to a higher number applying the 20% rule. 

 NOTE: A group of operators may, if operating the same aircraft type in similar operational 

conditions and having established common rules acceptable to each operators' 

Airworthiness Authorities, combine their fleets to form one fleet for the Sampling 

Program. 

 NOTE: If the operational conditions within an operator‟s fleet differ significantly (e.g. a subfleet is permanently based in a different climate condition) it is advisable to consider 

dedicated sample aircraft for this sub-fleet. 

Any significant changes to an operators fleet will require a review of the Sampling Program 

aircraft. This includes buying and/or selling aircraft and retiring aircraft from the fleet. 

Regarding rearranging of the sample fleet the following rules apply: 

- The above statements regarding sample size apply. 

Any aircraft in a fleet is protected by the respective sample aircraft of this operator‟s fleet. If 

a “non-sampling” aircraft would be integrated into a new operator‟s fleet it could become a 

sampling aircraft. However, no retroactive maintenance is required i.e. all inspections are to 

be performed at their next due. The inspection date could be calculated taking into account 

the last maintenance visit where a sampling inspection would have been performed if the 

aircraft had been part of the sampling fleet.

Example: An aircraft which was not a sample A/C is 7 years old has been acquired by 

another operator. “100% concept” 6 YE threshold inspection requirements have been 

accomplished during a maintenance visit when the A/C was 5.5 YE. No sampling inspection 

was performed (non sampling A/C).

In the new fleet, the A/C became part of the sampling fleet. 

The next sampling inspection for this A/C (6 YE / 6 YE sampling tasks) should be 

performed 6 YE after the last maintenance visit, therefore at the A/C age of 11.5 YE. 

Presumably, this would be the next 12 YE inspection event for this A/C, therefore the 12 YE 

sampling threshold inspection would be performed at this A/C age, too. 

NOTE: If an operator‟s established sample fleet consists of only 1 aircraft, the next check 

containing sampling inspections (e.g. 6 YE inspection) should be performed on this aircraft 

before it is removed from the sample fleet and replaced by another one (change of status). 

This is to achieve inspection data which are representative for the specific environment / 

operation. 

- If an aircraft is added to the fleet for a limited time it is advisable to review the sample fleet 

composition with special care. In particular, aircraft should not be removed from an 

established sample fleet in exchange for an aircraft being foreseeable in the fleet for a 

limited time only. 
A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: D7

- Since every case is specific, an acceptable agreement should be sought with the operators' 

Airworthiness Authorities. The operator should contact AIRBUS if there are doubts how to 

apply the above rules for a particular case. 

 

6.3 SAMPLING PROGRAM ILLUSTRATION

 The illustration shows the arrangement of inspections for a typical SSI with sampling and 

100% requirements: 

 The Sampling Program aircraft should first be selected before the subsequent planning of the 

SSI details.

7. CORROSION PREVENTION AND CONTROL PROGRAM (CPCP)

7.1 INTRODUCTION

The Structures section includes tasks to control corrosion to Level 1 or better on all structural 

details, elements or assemblies which contribute significantly to carrying flight, ground, 

pressure or control loads, and whose failure could affect the structural integrity necessary for 

the safety of the aircraft. 

All Corrosion Prevention and Control Program (CPCP) requirements are indicated by the code 

„CPCP‟ in the CPCP column.

Some calendar-time tasks are also covered by the Sampling Program, i.e. they have a 

Sample Threshold/Interval. For these tasks, the 100% Threshold is the time at which the task 

becomes a CPCP task. 

7.2 CORROSION LEVEL DEFINITIONS

 The definitions for the various Levels of corrosion are as follows: 

 Level 1 Corrosion

Corrosion damage that does not require structural reinforcement or replacement. 

 or, 

Corrosion occurring between successive inspections exceeds allowable limit but is local and 

can be attributed to an event not typical of operator usage of other aircraft in the same fleet 

(e.g. Mercury spill). 

 Level 2 Corrosion

Corrosion occurring between successive inspections that requires a single rework/blend-out, 

which exceeds allowable limits as defined by the manufacturer (SRM, SB, etc.), requiring a 

repair/reinforcement or complete or partial replacement of applicable structure. 

 Level 3 Corrosion

Corrosion found during first or subsequent inspection(s), which is determined (normally by the 

operator) to be an urgent airworthiness concern requiring expeditious action. 

7.3 CPCP RULES

The effectiveness of the Corrosion Prevention and Control Program is determined by following 

the General Rules applicable to the Structures section (refer to Paragraph 8) and the rules 

listed below (Refer also to CPCP Flow Chart and Decision Steps on following pages). 

 

 Level 1 Corrosion Findings

 Should inspections consistently reveal corrosion Level 1 findings for a given area during 

repeat inspections on particular aircraft operated in similar conditions, then the existing task is 

considered effective for the concerned area, and no change is necessary. 

Level 2 Corrosion Findings

 Should inspections reveal that corrosion is Level 2 for a given area during repeat inspections, 

then the existing task is not effective for the concerned area of the particular fleet. 

In order to control corrosion to Level 1 or better, consideration should be given to one or more 

of the following corrective actions: 

- Decreasing the inspection threshold/interval 
A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: D9

- Considering a higher inspection level 

- Re-considering the Concept (Sampling or 100%) 

- Application/More frequent application of Temporary Protection System 

- Embodiment of preventive modifications, where applicable 

- Installation of parts with improved protection standard, where applicable 

In this way, the CPCP is self-regulating and will adjust itself to the optimum program. 

 Level 3 Corrosion Findings

 Should inspections reveal that corrosion is Level 3 in a given area, then the existing task is not 

effective for the concerned area. 

In addition to the considerations given for Level 2 corrosion, an action plan calling for a onetime inspection of the concerned area should be expeditiously agreed with the local Aviation 

Authority and carried out on all aircraft of a similar age or older. 

 Airbus may be consulted to determine whether or not the airworthiness is affected. In this 

case all details of findings are to be promptly reported for detailed evaluation and the 

assistance required clearly expressed. 

 A periodic review of the Structures section, with particular attention to reported fleet data shall 

be scheduled to maintain the target of this program to control corrosion to Level 1 or better on 

all structural details, elements or assemblies which contribute significantly to carrying flight, 

ground, pressure or control loads, and whose failure could affect the structural integrity 

necessary for the safety of the aircraft.

FLOW CHART TO DETERMINE CORROSION LEVELS 
A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: D11

EXPLANATION ON FLOW CHART DECISION STEPS 

DECISION STEP A - CORROSION FINDING

There is a corrosion finding which is considered to be more than a negligible finding. 

DECISION STEP B - BEYOND ALLOWABLE LIMITS

The corrosion defect noticed on the considered aircraft is beyond the allowable limits as defined by the 

manufacturer (e.g. SRM, SB, etc.). 

DECISION STEP C - AIRWORTHINESS AFFECTED

The corrosion defect is beyond the allowable limits which prevents the aircraft from flying in a safe 

condition. 

When significant corrosion findings occur which could affect the structural integrity of the airplane 

Airbus can be consulted to determine whether or not the airworthiness is affected. In this case all 

details of findings are to be promptly reported for detailed evaluation and the assistance required 

clearly expressed. 

DECISION STEP D - DUE TO A NON TYPICAL EVENT

For the purpose of the flow chart, a non-typical event is an event which is considered to be not 

representative of the events which normally occurs or could occur in the concerned area. 

As examples: 

- mercury spillage 

- corrosive fluid spillages when they are demonstrated to be exceptional, however when they are 

noticed to be systematic they cannot be considered as non-typical. 
A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: D12

8. GENERAL RULES APPLICABLE TO THE STRUCTURE SECTION

1. The Maintenance tasks are to carried out "at or before" the limits stated for Sample 

Threshold/Interval and 100% Threshold/Interval. 

2. The Threshold is the time at which the first maintenance task is due: 

- For tasks in FC or FH, the Sample Thresholds and 100% Thresholds are counted from 

first flight, 

- For tasks in Years, the Sample Thresholds and 100% Thresholds are counted from 

date of initial delivery from manufacturer, unless otherwise stated. 

3. For repeat maintenance tasks, the interval starts at the time of the last maintenance task 

performed.

4. The thresholds and intervals quoted in calendar time in this section include aircraft time in and 

out of service. In other words, operators will not, in general, be allowed to take credit for time 

out of service or storage periods to extend corrosion inspection intervals. 

5. It is assumed that the structure to be inspected is in a state of cleanliness, which allows a 

satisfactory inspection to be carried out at the required inspection level. 

Where existing Temporary Protection System (TPS) permits clear assessment of the condition 

of the structure, then that TPS may remain in place for the inspection. 

6. If damage is found or suspected (such as bulging skin) then the full extent of any damage 

must be clearly identified using appropriate inspection techniques and/or disassembly when 

necessary. This may require additional access to that stated for the maintenance task. 

 All damage is to be evaluated and repaired in accordance with documentation acceptable to 

the relevant Airworthiness Authority. 

7. If inspections indicate evidence of deterioration, appropriate further actions must be taken to 

prevent similar deteriorations from occurring in the operators fleet. 

 For corrosion findings refer to CORROSION PREVENTION AND CONTROL PROGRAM in 

this section.

 Operators shall report inspection results related to SSIs to the manufacturer in accordance 

with the A318/A319/A320/A321 Reporting System, refer to Appendix 6. 

8. Ensure that all drain holes and drainage paths are clear from obstruction. 

9. The following applies to Temporary Protection System (TPS) application: 

a. Prior to application of TPS, perform an inspection of the area at the inspection level for the 

task quoted in calendar time. 

b. For those items/areas where TPS application is quoted in the TPS column, the integrity of 

the existing TPS is to be checked to determine if additional application is required, which 

will be done on an “as necessary” basis. If cleaning has been done (with solvents, or 

alkaline cleaners, or high pressure water and solvent, or steam and solvent), TPS must be 

reapplied. If TPS film is locally damaged, TPS must be removed then must be reapplied 

on these TPS-damaged areas. 

c. The Type and Grade of TPS to be applied is provided in the TPS column. Alternative 

Types and Grades may be used, where applicable. 

d. When TPS is only applied to a selected item/area within a task boundary, details are 

provided as a note in the Task Description column. 

e. Sampling Program tasks do not have TPS selected. If an operator chooses to apply TPS 

to a particular item/area for aircraft inspected in accordance with the Sampling Program, 

these aircraft are no longer representative of the non-sampled aircraft. In this case, TPS 
A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: D13

must be applied to all aircraft in this area, including the aircraft not selected for sampling. 

This task then effectively becomes 100% for those specific aircraft. 

f. When TPS application is not allowed on complete area/item, this is highlighted in the TPS 

column. 

CAUTION: 

DO NOT APPLY TEMPORARY PROTECTIONS ON OXYGEN SYSTEMS, CONTROL 

CABLES, PULLEYS, INSULATION BLANKETS, ELECTRICAL WIRING, SELF-LUBRICATED 

BEARINGS AND LUBRICATED SURFACES. DRAIN VALVES AND ALL OPEN ORIFICES 

ARE TO BE PROTECTED FROM INGRESS PRIOR TO TEMPORARY PROTECTION BEING 

APPLIED. 

10. Ensure wet insulation blankets are dried prior to re-installation, or replaced with new. 

11. The requirements quoted in years have been established by assuming aircraft operation in a 

"typical" environment. Operators who routinely deviate from operation in a "typical" 

environment e.g. by transporting seafood products, should make appropriate adjustments to 

their program. 

12. Inspection intervals recommended for surveillance of deterioration caused by the environment 

in fuel tank area (microbiological corrosion) should be adjusted by individual operators, 

considering their own in-service experience and operational environment. 

13. Based on reports made through the A318/A319/A320/A321 Structure Reporting System, 

AIRBUS will: 

- Inform all operators of any significant discrepancies discovered on the 

A318/A319/A320/A321 Fleet. 

- Make the appropriate recommendations. 

14. Additional information concerning SSI inspections is provided in AIRBUS supporting 

publications for the A318/A319/A320/A321 aircraft: 

- Maintenance Planning Document (MPD) 

- Aircraft Maintenance Manual (AMM)

- Non-Destructive Testing Manual (NTM) 

- Structure Repair Manual (SRM) 

 - Consumable Material List (CML) 

15. All tasks with "CPCP" quoted in the CPCP column are to be considered as CPCP tasks. 

16. The condition of the paint system should be verified during the inspections. Re-protection 

should be applied where necessary 

17. “Touch and Go” Flight Cycles can be neglected if they are less than 5% of the total number of 

Flight Cycles up to threshold inspection or between two consecutive inspections. 

Each “Touch and Go” cycle above 5% is to be counted as one Flight Cycle, up to threshold 

inspection or between two consecutive inspections. 

18. In case of insulation being fitted in the inspection area, it is specified on a task by task basis 

whether the insulation has to be displaced or to be removed to perform the inspection 

properly. For tasks transferred to ZIP, displacement of insulation is considered adequate 

19. Alternative inspection method 

SAFAM maintenance documents list alternative inspection methods for some items. In case 

the inspection requirements differ between the alternative inspections, the following rule 

applies when changing from a short interval inspection level (e.g. DET) to a high interval 

inspection level (e.g. SDI).

The initial inspection of the new method (SDI) has to be accomplished at the old inspection 

method due date. 

Once this was accomplished, the new inspection method interval can be applied. 
A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: D14

9. WEIGHT VARIANT APPLICABILITY

 

Some SSIs have different fatigue inspection requirements for the various Weight Variants (WV) of an 

aircraft type. The Weight Variant represents the delivery standard of each aircraft. 

The applicable Weight Variant (delivery standard) for each individual aircraft can be found in Table 1 

of the “Aircraft Allocation List” in the Structure Repair Manual (SRM) introduction. 

Table 2 of the “Aircraft Allocation List“ gives additional data for aircraft which have the Weight 

Variant status amended due to modifications or Service Bulletin embodiment. 

To minimise the number of individual inspection requirements, the Weight Variant requirements 

have been Grouped where they are similar. The Group number is stated in the Structures section 

“APPLICABILITY“ column. Refer to the details below: 

WV groups are only stated where necessary. In other cases the aircraft Model, e.g. A320, or 

aircraft model and series, e.g. A320-200, have been retained where these cover all requirements. 

For A/C, that have been subject to a WV (Weight Variant) change through a service bulletin 

embodiment, the maintenance requirements that apply are those with the lowest threshold and 

interval figures applicable to this A/C during service life regardless of the current WV of that subject 

aircraft. 

The following WV grouping applies:

Rev 18 Page: E1

SECTION E

ZONAL 

1. GENERAL

This section provides the General Visual Inspection (GVI) requirements for each aircraft zone to 

inspect: 

- system and powerplant installations for security, 

- structures for general condition. 

- Electrical wiring installation for general condition 

Inspections are to be accomplished at or before the stated intervals. 

The inspections are specified by quoting the relevant zone number, zone description, access 

requirements, intervals and applicability. 

The extent of the inspection is defined by the preparation and access requirements. The zone is 

to be inspected as visible with the relevant access open. 

There are zones which will require more than one inspection at different intervals, because the 

depth at which the zone is to be examined may necessitate differing levels of accessibility. 

The tasks inspect: 

 - Structures by looking for signs of accidental damage, corrosion and cracks and for general 

condition of fasteners. 

 - Systems installations for proper attachment and security (components, wiring, ducting, 

tubing, pulleys bearings, electrical bonding, leaks, chafing marks etc...). 

- Electrical wiring installation for general condition (cracks, loose clamps, chafing, etc...)

 - The general condition of any fairings, panels or other items which are removed/opened to 

gain access to a particular zone. 

The items in the zone are to be visually inspected from within touching distance where physically 

possible. A mirror may be necessary to enhance visual access to all exposed surfaces in the 

inspection area. 

To facilitate the discrepancy identification, it is expected that the area to be inspected is clean 

enough to minimise the possibility that accumulated dirt or grease might hide unsatisfactory 

conditions. Any cleaning that is considered necessary should be performed before Zonal 

inspection. 

With respect to General Rule 16 in Section B, operators shall consider that all ZIP tasks are 

required to support compliance to EWIS requirements. An individual marker “(EWIS)” is given 

after the task description to highlight this as appropriate. 

2. COMPATIBILITY WITH TASKS FROM SYSTEMS AND STRUCTURES SECTIONS 

The inspection tasks do not provide a complete summary of all items to be inspected in the 

affected zone. It is therefore considered that the person performing the inspection has an 

adequate knowledge of aircraft construction and of its system and wiring installation. 
 A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: E2

Tasks arising from Enhanced Zonal Analysis Procedure (EZAP), which are not fully covered by 

standard Zonal tasks (Section E), are included in ATA chapter 20 of the System and Powerplant 

(Section C) of the MRB Report and are identified by the marker “(EWIS)” following the task 

description. These dedicated tasks remain under the responsibility of the Zonal Maintenance 

Working Group. 

General Visual Inspections transferred from the systems section and structures section are 

considered as being adequately covered by Zonal tasks. Therefore, a dedicated inspection is not 

required for these SSIs and MSIs if the equivalent ZIP task is performed at least as frequently as 

the intervals stated for those inspections in the System and Powerplant and Structures Sections. 

Appendix 9 provides reference information about GVIs covered by Zonal tasks. 

As a result of the CPCP requirement to control corrosion to Level 1 or better (refer to section D), 

operators shall report corrosion findings to the manufacturer in accordance with the Maintenance 

Task Reporting System (Refer to Appendix 6). 

All intervals for ZIP task were originally defined in calendar time. This was done according to 

MSG-3 and the PPH and no secondary parameter for ZIP tasks was defined. 

However, because the usage parameter concept is applied throughout all sections, some 

systems GVI tasks could only be transferred to ZIP if a second interval is given which provides a 

limitation in terms of Flight Hours (FH). The second parameter is only given to ZIP tasks where 

the FH interval of a transferred task is potentially exceeded even if the A/C is still operated within 

the utilization window as given in Section A, para 2. 

Example: An A/C with a utilization of 3000 FH/year would achieve 1000 FH within 4 MO. A 

systems task with an interval of 750 FH can only be transferred into a ZIP task with an interval of 

4 MO if this calendar interval is accompanied by a 750 FH interval. The task is then due at 

whatever interval is reached first. 

Operators have the possibility not to consider the secondary interval quoted in FH. However, 

then they are obliged to track the transferred systems tasks individually to ensure that the task 

intervals as quoted for the MSI task concerned would not be exceeded. 

3. NOTES FOR SECTION E

 NOTE 1 : Insulation to be displaced as required to complete required inspection. 

 NOTE 2 : Deleted. 

 NOTE 3 : Interval may be adjusted by individual operators in consideration of their own inservice experience and operational environment. 

 NOTE 4 : Deleted. 

 NOTE 5 : Deleted. 

4. RULES APPLICABLE TO SECTION E

1. Inspections are to be accomplished on each aircraft. 

2. DELETED

Note: The sampling program for Zonal tasks has been deleted with OCT 01/06 revision of the 

MRBR. 
 A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: E3

5. INSPECTIONS MORE FREQUENT THAN 750FH / 4 MO.

The routine content of inspections with frequencies below 750FH / 4 MO shall be developed by 

the operator. Consequently, even when the Zonal working group has used its experience or 

engineering judgement to select an interval below 750FH / 4 MO, this has not been included in 

the Zonal Section. However, since the justification for these inspections was based on the 

likelihood of random accidental damage, they have been stated below for completeness. 

 It is recommended that these inspections are considered by all operators, for inclusion in their 

routine maintenance programs. Recommended intervals are provided where no similar 

inspections already exist on comparable fleets. 

 It is recognised that these inspections are of a lesser intensity than a General Visual Inspection, 

since they are to be performed 'from the ground, as far as visible'.

6. EXPLANATION OF ZONAL SECTION FORMAT

Detailed information is given below concerning the format of the inspection requirements provided on subsequent pages. 

 

 

1- This column indicates the zonal task number, e.g. ZL 151-01-1. It is composed of 8 digits as follows:

ZL XXX – XX – X 

 

The Zone number is represented by the three first digits, 151-01-1. The first digit, 151-01-1, is in accordance with the A318/A319/A320/A321 

ATA 100 breakdown, showing the major section where the zone is located e.g. 100 for Lower Half of Fuselage. For the wing zones, all ZIP task 

numbers start with 5 (e.g. 531-01-1) although they cover LH and RH wing i.e. zones 531 and 631. The second digit, 151-01-1, is also in 

accordance with the A318/A319/A320/A321 ATA 100 breakdown, showing the sub section where the zone is located e.g. 150 for Aft Cargo 

Compartment. For following symmetric zones, which are located on LH and RH side, the ZIP task number only refers to the LH zone though they 

cover both LH and RH items (e.g. 334-02-1 covers zones 334 and 344): HTP, LDG, Pylons, Doors. 

The third digit, 151-01-1, provides more details where the area is located, e.g. RH or LH side of the applicable zone. Symmetric zones, which are 

located on LH and RH side (e.g. fwd cargo compartment zones 131/132, zones 263/264), could be covered by only one task. In this case the 

zone number of the LH zone is for the third digit task (e.g. ZL-251-01-2 for LH (251) and RH (252) part of aft passenger compartment). 

The Sequence Number is composed of two digits. It follows the Zone number and is separated by a dash e.g. 151-01-01. It identifies different 

depth of inspections at different intervals. These two digits are also changed when the inspections have a major difference in access (e.g. 

actuator removal). 

The Applicability Index is composed of one digit. It follows the Sequence Number and is separated by a dash, 151-01-1. It identifies different 

applicability e.g. aircraft series, mod status etc ... This digit is also used to differentiate between minor access differences e.g. different access 

panel numbers and differences in reference information.

2- This column indicates the access and preparation requirements to adequately perform the inspection. 

 (i) It lists all access panels, doors and fairings or indicates boundaries between the access panels have to be opened or removed.

 (ii) It defines the configuration of the aircraft if necessary, e.g. "SLATS AND FLAPS EXTENDED".

 (iii) The removal or deplacement of insulation is indicated by either 'Insulation' or 'NOTE 1' respectively. 

 (iv) To take account of customisation and the Flexible Cabin Concept: 

 Galleys, toilets or ACT are quoted in conjunction with the note "IF INSTALLED" 

 Floor panels are not given individual panel numbers, the term "FLOOR PANELS FROM FR XX TO FR XY" is used for 

simplicity where required 

 3- This column indicates the Zone(s). 

 4- This column provides the description of the zone, which is shown underlined. In certain cases, additional information is provided in 

brackets to precise the inspection area. 

 e.g. ELEVATOR

 (AREA BETWEEN RIBS 8 AND 9) 

 

 5- This column provides the inspection interval. 

 For the ZIP the threshold is equal to the interval. The interval starts at the time of the last inspection performed. 

 

 6- This column indicates the aircraft type/model and/or MOD status or engine type to which this requirement is applicable.

Rev 18 Page: F1

SECTION F

REQUIREMENTS FOR U.S. OPERATORS

GENERAL

This section details the requirements which must be embodied in sections A, B, C, D and E of this 

report to give the initial maintenance requirements acceptable by the Federal Aviation Administration 

(FAA) Maintenance Review Board (MRB) for the Airframe, Powerplant, Systems and Components for 

the A318, A319, A320 and A321 aircraft operated by United States certificated operators. 

The basic requirements outlined in this report are intended to allow each United States certificated 

operator to develop a maintenance program that would be compatible with its own maintenance 

policies and requirements and to assist the operator in the preparation of its original Operations 

Specifications and to further guide the assigned FAA inspector in the approval of those Operations 

Specifications. This information may be maintained in separate documents providing such documents 

are appropriately referenced on the Operations Specifications. 

The requirements which must be embodied are listed as follows under the relevant section heading. 

SECTION A

1. The responsible FAA inspector shall ascertain that all of the applicable scheduled 

maintenance/inspection requirements in this report are included in the air carrier’s initial 

continuous airworthiness maintenance program. 

SECTION B

1. Certification Maintenance Requirement tasks/intervals arising from analyses (e.g. System Safety 

Assessments) performed as part of the Type Certification process are given in Airbus document 

ST4/955.061/89. Appendix 1 of this MRB Report indicates where this document is located. The 

process by which CMRs are identified is independent of the MSG-3 analysis process. The CMR 

document is the controlling document for all tasks identified as CMRs. 

2. Inspections, hydrostatic test and life limits of pressure cylinders will be accomplished as set forth in 

CFR 49, 180.205 currently in effect and FAA Order 8000.40D. For foreign manufactured 

containers, inspect, retire, and test per manufacturers technical data currently in effect. 

3. An Operator may not take credit for tasks described in this MRB Report, when accomplished by 

the flight crew in accordance with an approved/accepted flight deck normal check list as per FAA 

AFS-300 Policy dated October 29, 1996.

SECTION C

MSI 345200 AIR TRAFFIC CONTROL 

The following task has to be added: "ATC trans/ALT reporting check"; interval 24 months

APPENDIX 1

CERTIFICATION MAINTENANCE REQUIREMENTS (CMR)

AND

AIRWORTHINESS LIMITATION ITEMS (ALI)

The Airworthiness Limitations Section (ALS) provides those Instructions for Continuous Airworthiness 

that are required by FAR/JAR 25 Appendix H, paragraph 25.4. The ALS is the repository for the 

following stand-alone documents that are approved independently from each other: 

Part 1: Safe Life Airworthiness Limitation Items 

Part 2: Damage-Tolerant Airworthiness Limitation Items 

Part 3: Certification Maintenance Requirements 

Part 4: Ageing Systems Maintenance 

Part 5: Fuel Airworthiness Limitations 

These documents are approved by the Primary Certification Authority (EASA) and are referred to in 

the aircraft Type Certificate Data Sheets. 

The ALS Parts are issued in digital format. They are published on AirbusWorld. 

Airbus advises the availability of new revisions of the ALS Parts by issuance of an automatic 

notification (NICE) that provides guidance on downloading the document from AirbusWorld.

 A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: APX 4.2

FUNCTIONAL CHECK:

A quantitative check to determine if one or more functions of an item performs within specified 

limits. 

FUNCTIONAL FAILURE:

How an item failed to perform its function. 

HIDDEN FUNCTION:

1. A function which is normally active and whose cessation will not be evident to the 

operating crew during performance of normal duties. 

2. A function which is normally inactive and whose readiness to perform, prior to it being 

needed, will not be evident to the operating crew during performance of normal duties. 

INSPECTION:

An examination of an item against a specific standard. 

INSPECTION - GENERAL VISUAL:

A visual examination of an interior or exterior area, installation or assembly to detect obvious 

damage, failure or irregularity. This level of inspection is made from within touching distance, 

unless otherwise specified. A mirror may be necessary to enhance visual access to all exposed 

surfaces in the inspection area. This level of inspection is made under normally available 

lighting conditions such as daylight, hangar lighting, flashlight or drop-light and may require 

removal or opening of access panels or doors. Stands, ladders or platforms may be required to 

gain proximity to the area being checked. 

INSPECTION - DETAILED:

An intensive examination of a specific item, installation or assembly to detect damage, failure 

or irregularity. Available lighting is normally supplemented with a direct source of good lighting 

at an intensity deemed appropriate. Inspection aids such as mirrors, magnifying lenses, etc. 

may be necessary. Surface cleaning and elaborate access procedures may be required.

INSPECTION - SPECIAL DETAILED:

An intensive examination of a specific item, installation, or assembly to detect damage, failure 

or irregularity. The examination is likely to make extensive use of specialised Inspection 

Techniques and/or equipment. Intricate cleaning and substantial access or disassembly 

procedure may be required. 

LUBRICATION & SERVICING:

Any act of lubricating or servicing an item for the purpose of maintaining its inherent design 

operating capabilities. 

MAINTENANCE SIGNIFICANT ITEMS (MSI):

Items identified by the manufacturer whose failure: 

a) Could affect safety (group or flight), and/or 

b) Is undetectable during operation, and/or 

c) Could have significant operational economic impact, and/or 

d) Could have significant non-operational economic impact.

Steering Group 3. 

OPERATIONAL CHECK:

A task to determine that an item is fulfilling its intended purpose. Does not require quantitative 

tolerances. This is a failure finding task. 

OTHER STRUCTURE:

Structure which is judged not to be a Structural Significant Item. "Other Structure" is defined 

both externally and internally within zonal boundaries. 

RESTORATION:

That work (on/off the aircraft) necessary to return the item to a specific standard. 

SAMPLING CONCEPT:

Inspections on specific aircraft selected from those which have the highest operating usage in 

order to identify the first evidence of deterioration in their condition caused by fatigue damage 

or corrosion. 

SAFE LIFE STRUCTURE:

Structure which is not practical to design or qualify as damage tolerant: its reliability is 

protected by discard limits which remove items from service before failures are expected. 

SCHEDULED MAINTENANCE CHECK:

Any of the maintenance opportunities which are pre-packaged and are accomplished on a 

regular basis. 

STRUCTURAL SIGNIFICANT ITEM (SSI):

A structural detail, structural element, or structural assembly which is judged significant 

because of the reduction in aircraft residual strength or loss of structural function which are 

consequences of its failure. 

TASKS - MAINTENANCE:

An action or set of actions required to achieve a desired outcome which restores an item to or 

maintains an item in serviceable condition, incl. inspection and determination of condition. 

THRESHOLD:

The specific value of a usage parameter (flight cycles, flight hours, etc...) at which the first 

inspection of some particular level or method should be conducted. 

VISUAL CHECK:

APPENDIX 6

MAINTENANCE TASK REPORTING SYSTEM

This MRBR Appendix was previously only applicable to structure inspection task reporting. 

The structures reporting system was based on a paper reporting format. It has been completely rewritten to: 

- Indicate a new on-line method of maintenance task reporting 

- Make it applicable to all maintenance tasks; systems, structure and zonal 

Most operators plan directly from the Maintenance Planning Document, as it contains all repetitive 

maintenance tasks from all sources (MRBR, ALS, SBs, SILS etc ...). The new reporting format is therefore 

based on the MPD task numbering format, based on the latest revision of the MPD. The format is similar to 

the one used to collect data for recent evolution exercises. 

The Airbus database has been designed and dimensioned to receive data on a continuous flow basis. 

Operators are therefore requested to report data from all maintenance checks. The data should include all 

task results, findings and nil findings. The reporting and collection of nil-findings allows a computation of 

finding rate (finding/nil-finding ratio) which may be used for future maintenance program optimization. 

Please refer to AirbusWorld eSite: Airbus World > Maintenance & Engineering > Prepare Maintenance > 

Optimize maintenance management > Optimize maintenance program > Report my check records. 

This then gives access to the appropriate reporting spreadsheet and the associated guideline “MPD Task 

Reporting Guidelines”. 

All reports should be sent to MPDtask.Reports@Airbus.com. Any related questions should be sent to the 

same address. Operators will receive an acknowledgement for data reports. 

Analysis of the reported data will enable Airbus to monitor the effectiveness of the Maintenance Program 

and to further optimize it. 

Airlines who report data will also have the possibility to benchmark task findings statistics against the 

reported data of other Airlines. 

Operators may continue to use the previous CPCP reporting sheet (published until MRBR Rev. 15) for their 

own purposes. They can, however, not be used as an input to the Airbus database. 
A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: APX 7. 1

APPENDIX 7

HIRF/LIGHTNING PROTECTION 

1) Background

In 1997, approximately ten years after development of the initial A320 MRB Report, the Type 

Certification authorities verbally requested the manufacturer to address the subject of the maintenance 

of HIRF/Lightning protection in a similar way to that agreed for the A330/A340 program. For that 

aircraft program, the MRB did require the manufacturer to identify an appropriate method by which to 

confirm that in-service operation will not reduce the HIRF and Lightning protection to a level that is 

inadequate to maintain Type Certification objectives. 

In addition to this verbal request, approved HIRF/Lightning Protection maintenance requirements are 

beneficial in order to support operators who have to show compliance with FAA’s Flight Standards 

Information Bulletin for Airworthiness (FSAW) 97-16A. 

Airbus has reached agreement with the MRB and the Aircraft Certification Offices of EASA, FAA and 

Transport Canada that compliance may be shown by a combination of two methods: 

a) Identification of dedicated maintenance tasks to supplement the inspections already 

included in Sections C, D and E of the MRB Report. These additional tasks are to be 

performed by operators on all A318/A319/A320/A321 aircraft at defined intervals. They are 

listed in this Appendix to the MRB Report and are approved by the MRB. 

b) Identification of an A318/A319/A320/A321 ‘HIRF/Lightning Protection Assurance Plan’ that 

requires the manufacturer to perform specific tests on a representative sample of the world 

A318/A319/A320/A321 fleet at specified intervals. These tests and intervals are agreed 

with the Aircraft Certification Offices. See paragraph 5 for further details. 

Though the specific HIRF / Lightning related scheduled tasks are identified in an Appendix to the MRB 

Report, operators are to consider them as MRB tasks and include them in their approved maintenance 

programs. 

2) HIRF and Lightning Protection – design concept

The coupling phenomena between lightning or HIRF and the aircraft give rise to induced threats which 

can interfere with electrical / electronic systems. 

HIRF has a real-time effect on systems but results in no residual damage. A HIRF encounter cannot be 

detected after the event by a physical examination of hardware. 

A Lightning encounter can result in permanent physical degradation of hardware as well as possible 

real-time effects. 

Aircraft protection against HIRF and Lightning indirect effects is achieved by complementary means: 

a) aircraft structure continuity 

This continuity is ensured by metal to metal contact and bonding leads. 
A318/A319/A320/A321 MRB REPORT 

Rev 18 Page: APX 7. 2

b) electrical wiring protection 

In exposed areas, overshielding ensures protection of cables. This is provided by: 

- raceways in wings 

- braided conduits in the belly fairing, fin, tailplane, on engines, in tail cone and 

landing gear area and at interface between pylon/wing and wing/fuselage 

- individual shielding for engine cables (nacelle, pylon, wing) 

c) equipment protection 

In addition to the equipment inherent protection (circuit layout and box design), 

clamping and filtering devices at inputs/outputs prevent damage from voltage/current 

resulting from Lightning and HIRF. 

d) systems architecture 

Systems architecture is designed to achieve systems safety and availability objectives 

and contributes to increasing the non-susceptibility of systems to HIRF and Lightning 

effects. Main features are: 

- segregation of electrical wiring routes 

- different locations of equipment 

- redundancy and dissimilarity 

For the types of protection described in paragraphs a, b and c, appropriate means have been 

determined to confirm the continued integrity of the features. The protection described in 

paragraph d will not degrade and thus is not addressed. 

3) Identification of dedicated tasks in this Appendix

At aircraft level, for each item or group of items providing HIRF/Lightning protection, the following 

analysis has been performed: 

a) from parameters such as type and location of protection element the consequence of 

protection degradation has been assessed. 

b) from design features such as material, installation techniques, etc, the causes of 

degradation have been identified. 

c) from the type of degradation foreseen, the location of items and their accessibility, the 

most applicable and effective task to detect the discrepancy has been selected. 

d) from any systematic degradation seen in-service, the most effective task to find the 

discrepancy has been selected. 

At equipment level, taking into account functional criticality, a dedicated review of components fitted 

with Lightning protection devices that also act as HIRF protection has been performed. Component 

Maintenance Manuals (CMMs) have been verified to check for the presence of appropriate test(s) 

using Automatic Test Equipment (ATE) prior to re-release for service. Where test(s) are not required, 

justification is provided to demonstrate that the safety objective is achieved. 

The tasks were not identified using an MSG-3 type logic approach.

Rev 18 Page: APX 7. 3

4) Scheduled Maintenance philosophy

With respect to structure continuity, existing General Visual Inspections provided by the Zonal Section 

(MRB Report Section E) are applicable and effective. 

With respect to electrical wiring, analysis has highlighted that for some specific devices the GVI 

required as part of the ZIP is not adequate to identify degradation of HIRF/Lightning protection. For 

these design features, this Appendix identifies the need for either a dedicated GVI, a higher level of 

inspection, a security check (tactile check) or an impedance loop test to ensure that degradation will be 

detected. In addition, service experience has highlighted some specific areas where systematic 

deterioration of the protection is possible. This Appendix identifies recommended tasks to address 

these findings, some of which are valid only on aircraft with a particular modification standard. 

The number of tasks required by this Appendix have been kept to a minimum and the type of task has 

been identified as the least intrusive compatible with the target of identifying degradation that causes a 

loss of protection below certification values. 

The accomplishment procedures to satisfy the tasks are given in the Aircraft Maintenance Manual. No 

task requires the disconnection of connectors or dismantling of fixations, restraints or bonding leads 

though this may be necessary if there is evidence of degradation. 

For the majority of the wiring installation, it is concluded that significant deterioration will be identified 

and corrected during application of maintenance tasks as identified defined in the Zonal Section. To 

support this conclusion, Airbus have agreed to establish a HIRF/Lightning Protection Assurance Plan 

(see paragraph 5). Findings resulting from the activities detailed in this Plan will be used to justify 

amendments to this Appendix. 

5) HIRF/Lightning Protection Assurance Plan

The A318/A319/A320/A321 HIRF/Lightning Assurance Plan is required to: 

a) monitor the effectiveness of the scheduled maintenance tasks identified in the MRB Report 

and its Appendix 7 and identify any shortcomings 

b) address the special requirements for HIRF/Lightning continuous airworthiness arising from 

Type Certification issues 

 

Airbus will measure, on selected aircraft, the level of electrical installation electromagnetic protection. 

This protection will be measured at the level of the installation and will be compared to that of a new 

aircraft. Using a loop tester, a measurement is made of the impedance of a loop created by a braided 

conduit, its connections to structure and the structure itself. 

The initial sample size was 5 aircraft over a period of 5 years (Campaign N° 1 and 2). In agreement 

with Aircraft Certification Offices, the sample size had been decreased to 3 aircraft every 5 years for 

campaign N° 3. This sample (3 aircraft over 5 years) has been kept for the campaign N° 4. Future 

sample sizes are being reviewed after each campaign with Aircraft Certification Offices. 

The tests are being performed at the opportunity of a Heavy Maintenance Visit.. These tests are 

performed by the manufacturer and may be carried out concurrently with other maintenance activities. 

The power on/off status of the aircraft is not critical. 

Airbus is responsible for identifying appropriate aircraft and for making the initial contact with the 

operator at least four months prior to the date of the Heavy Maintenance Visit. All operators should be 

prepared to provide an aircraft for this purpose. 

Details of the A318/A319/A320/A321 HIRF/Lightning Assurance Plan are given Airbus document ref 

513.0183/99.

Rev 18 Page: APX 7. 4

6) L/HIRF task evolutions – short-term extension or variation 

Evolution of Appendix 7 tasks should be assessed in a similar way to Zonal Inspections and calendar 

related structural inspections. They are not classified as either safety or non-safety related. However, 

though intervals should be adjusted in accordance with experience the tasks shall not be deleted from 

an operators program. It is expected that escalations justified by good experience will be limited to a 

value necessary to maintain the task in the same check package. 

Short-term extensions or variations are permitted in exceptional circumstances as for other scheduled 

maintenance tasks not subject to CN/AD action. The maximum value of these one time extensions is 

in accordance with local authority agreements.

APPENDIX 9

GENERAL VISUAL INSPECTIONS COVERED BY ZONAL TASKS

1. Introduction 

This Appendix contains tables for GENERAL VISUAL INSPECTIONS COVERED BY ZONAL TASKS. All 

GVIs that are identified by the relevant MSI or SSI analyses and have been accepted for coverage by a 

Zonal Task (Section E) are listed in two tables. 

In order to ensure a two-way traceability this appendix has 2 tables: 

Table „A‟ links the Zonal task to the MSI or SSI GVIs that are covered by this Zonal Task. 

Table „B‟ links the MSI or SSI GVI to the Zonal task(s) that covers this Systems or Structures GVI. 

This Appendix 9 replaces the “ZIP REFERENCE” information in Section C and Section D as well as the 

“MSI/SSI REFERENCE” information in Section E.

For traceability reasons, Sections C and D continue to keep all GVI task references listed in MRBR Rev. 

15 that are or will be covered by Zonal tasks. The task number is kept together with the information “TASK 

COVERED BY ZIP, SEE APPENDIX 9” in the task description column. 

Structures or Systems GVIs listed in this appendix are considered adequately covered by Zonal tasks. 

Therefore dedicated inspection tasks are not required for these GVIs, if the equivalent Zonal task is 

performed at least as frequently as the Structures or Systems GVI interval.
