### Sub-part 3-0 INTRODUCTION

From revision 24 and on, the content of:

A318/A319/A320/A321 Certification Maintenance Requirements (CMR) Document (EASA version) (Referenced AI/ST4/993.436/88)

applicable to all A318/A319/A320/A321 models, has been transferred to the

A318/A319/A320/A321 Airworthiness Limitations Section (ALS)

Part 3 Certification Maintenance Requirements (CMR)

From revision 18 and on, the content of:

A318/A319/A320/A321 Certification Maintenance Requirements (CMR) Document (FAA version) (Referenced AI/ST4/995.061/89)

applicable to all A318/A319/A320/A321 models operated under FAA regulations, has been

transferred to the

A318/A319/A320/A321Airworthiness Limitations Section (ALS)

Part 3 Certification Maintenance Requirements (CMR)

This change is part of a process to provide Operators and Maintenance, Repair and Overhaul Organizations (MRO) with a series of stand-alone documents in a location dedicated to the

limitations.

The data provided under ALS Part 3 has been established with the following rules:

1. SCOPE

Though not addressed by the paragraph H25.4 of Joint Aviation Requirements (JAR) 25 Appendix H, CMRs may be considered as the systems equivalent to the structural Airworthiness Limitation Items. For this reason, it is considered appropriate to identify them as part of the ALS. This document constitutes the ALS Part 3 - Certification Maintenance Requirements.

Compliance with the requirements stated in this document is mandatory. No person may operate an aircraft to which an ALS applies except in accordance with the requirements of that ALS, unless otherwise agreed with the Authority of the State of aircraft registry.

This document is applicable from first delivery of an aircraft configuration into an Operator’s fleet. The starting time for CMR task intervals are defined in para 7 of this sub-section. Possible interval escalations must be justified in accordance with the procedure given in paragraph 6 of this sub-section. If a more restrictive CMR is issued on an aircraft configuration already in service, the requirement for existing Operators to follow the revised ALS Part 3 will normally be mandated by Airworthiness Directive (AD).

Non-compliance could suspend the validity of the Airworthiness Certificate.

### Airworthiness Directives dedicated to spec ific concerns may override the specific requirement(s) given in this document.

The identification of CMR tasks in no way diminishes the importance of non-CMR tasks and changes to these are subject to normal practices and procedures agreed between the Operator and the Authority of the State of aircraft registry.

2. APPLICABILITY

The applicability of this ALS Part 3 revision is restricted to the aircraft models listed below:

A318-111 A319-111 A320-111 A321-111

A318-112 A319-112 A320-211 A321-112

A318-121 A319-113 A320-212 A321-131

A318-122 A319-114 A320-214 A321-211

A319-115 A320-215 A321-212

A319-131 A320-216 A321-213

A319-132 A320-231 A321-231

A319-133 A320-232 A321-232

A320-233

Note: The engine Time Limits and Maintenance Checks are not included in this manual: refer to the relevant Engine Manufacturer Chapter 05 manual.

The CMRs contained in the ALS Part 3 are valid up to the following operational life applicable to A318/A319/A320/A321 systems installations:

Aircraft Series Flight Hours (FH)

A318-100 0 60000 FH A319-100 Excluding Corporate Jet Operations 0 60000 FH A319-100 Corporate Jet 0 77400 FH

A320-100 0 48000 FH

R A320-200 PRE 37734 PRE 39020 0 60000 FH

R A320-200 POST 37734 PRE 39020 0 80000 FH

N A320-200 POST 39020 120000 FH

A321-100 0 60000 FH

A321-200 0 60000 FH

Maintenance requirements and/or airworthiness limitations identified throughout ALS Part 3 may be superseded by Ageing System Maintenance requirements identified within ALS Part 4. In that case, it is Operator’s responsibility to consider the most restrictive of both requirements.

Note:

− MOD 37734 refers to Design Service Goal (DSG) extension of A320-200 aircraft from 60000 FH up to 80000 FH (Intermediate Service Goal, ISG).

− MOD 39020 refers to Design Service Goal (DSG) extension of A320-200 aircraft up to 120000 FH (Extended Service Goal 1, ESG1). N

### 3. MODIFICATIONS/REPAIRS NOT DEVELOPPED UNDER AIRBUS DOA CERTIFICATE

EASA. 21J.031

If an aircraft/a sub-assembly/a component/an item has a modification or repair embodied that has not been developed under the Design Organisation Approval (DOA) Certificate EASA. 21J. 031 (e.g. under a Supplemental Type Certificate) and which affects the content of the ALS Part 3, the Operator is responsible for obtaining approval by the relevant Airworthiness Authority for any necessary adaptations of the airworthiness limitations.

When such an aircraft/a sub-assembly/a component/an item is transferred from one Owner/Operator to another, the associated approvals and documents indicating the necessary adaptations of airworthiness limitations must be transferred as well.

4. ALTERNATIVE METHODS OF COMPLIANCE

Limitations of the ALS Part 3 may be negated by instructions given in an Alternative Method Of Compliance (AMOC). When limitations evolve in a revision of the ALS Part 3 subsequent to the issuance date of the AMOC, Operators are requested to contact Airbus for guidance. It is Operator’s responsibility to refer to the applicable limitations.

5. CRITERIA FOR IDENTIFICATION

CMRs are tasks arising from the Type Certification process, which are associated with the most significant failure conditions. These have been shown to be necessary either by System Safety Assessment (e.g. JAR 25.1309 compliance) or, in a minority of cases, by engineering judgement. These requirements are allocated to one of two categories (identified as One Star or Two Star) in accordance with the EASA agreed methodology.

Tasks associated with the following criteria are not identified as CMRs:

− Tasks associated with qualitative assessment (unless specifically requested by EASA),

− Tasks for which the maximum acceptable interval is in excess of the aircraft life,

− Tasks normally accomplished by the flight crew,

− Tasks considered being routine state of the art maintenance activity. For these, the safety reason for performing the task is considered to be immediately evident to the Operator and the Authority of the State of aircraft registry.

6. HANDLING OF CERTIFICATION MAINTENANCE REQUIREMENTS

A. One Star CMRs (*)

One Star CMRs specified in the ALS Part 3 are mandatory tasks and cannot be changed or deleted without the concurrence of the Primary Certification Authority (EASA). One Star CMR task intervals quoted in ALS Part 3 are absolute limitations and cannot be escalated without the concurrence of the Primary Certification Authority (EASA).

B. Two Star CMRs (**)

Two Star CMRs specified in the ALS Part 3 are mandatory tasks and cannot be changed or deleted without the concurrence of the Primary Certification Authority (EASA). R

### Two Star CMR task intervals may be adjusted in accordance with an Operator's approved escalation practices or an approved reliability program, but the task content may not be changed or deleted without prior Primary Certification Authority (EASA) approval.

This statement has been agreed on the basis that Operators with approved escalation practices or an approved reliability program make adjustments to their maintenance programs based on data collection and analytical techniques. It has been demonstrated that the use of such methods to manage a maintenance program does not give rise to

undue escalation.

7. STARTING TIME FOR CMR INTERVAL

This paragraph provides general rules related to the starting time to be considered for CMR interval counting according to the different usage parameters.

For CMR tasks whose interval is given in Calendar time, the starting time may be considered as the date of Transfer of Title to the first Operator of the aircraft, unless otherwise stated in the delivery documentation of the dedicated aircraft.

For CMR tasks whose interval is given in Flight Hours (FH), the starting time may be considered as the date of Transfer of Title to the first Operator of the aircraft, unless otherwise stated in the delivery documentation of the dedicated aircraft. Considering the very low number of Flight H ours performed between first flight and delivery, and the methodology used to define CMR task intervals, EASA agree to consider the date of delivery of the aircraft as the starting time for CMR tasks whose intervals are given in Flight

Hours.

For CMR tasks whose interval is given in Flight Cycles (FC), the starting time to be considered is the date of the aircraft first flight, unless otherwise stated in the delivery

documentation of the dedicated aircraft.

8. DEFINITIONS

Calendar time (Cal.): Thresholds/intervals in Years (Ye), Months (MO) etc...

Flight Cycle (FC): A complete take-off and landing sequence.

Flight Hour (FH): The accumulated time intervals between “wheels-off” and “wheelson”.

Interval: The period expressed in usage parameters like FH and/or FC and/or Calendar time between successive accomplishments of a specific task.

Operational Check: A qualitative check to determine that an item is fulfilling its intended purpose. It is a failure-finding task and does not require quantitative tolerances.

Functional Check: A quantitative check to determine if one or more functions of an item perform within specified limits.

ISSUE: JUN 15/12 ALS PART 3-0 PAGE: 5

© AIRBUS SAS 2012. All rights reserved. Confidential and proprietary document. 

### Visual check Observation to determine that an item is fulfilling its intended purpose. It is a failure finding task and does not require quantitative tolerances.

Detailed lnspection: 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.

First flight: Unless otherwise stated, the use of this term in the ALS Part 3 implies that the life accumulated before the aircraft delivery date/transfer of title date (e.g. as a result of test flights) must be

taken into account.

9. EXCEPTIONAL SHORT-TERM EXTENSION

Since CMR intervals are based on statistical averages and reliability rates, an exceptional short-term extension for a specific CMR in terval may be made on one aircraft for a limited period of time without jeopardising safety.

The term 'exceptional short-term extension' is defined as an increase in a CMR interval that may be needed to cover an uncontrollable or unexpected situation. Repeated use of such extensions, either on the same aircraft or on similar aircraft in the Operator's fleet, should not be used as a substitute for good management practices. Short-term extensions must

not be used for fleet CMR escalation.

Unless noted adjacent to the task, for all CMRs (One Star and Two Star) identified in this ALS Part 3, it has been accepted by the Primary Certification Office (EASA) that short-term extensions up to the following maximum val ues may be granted without consultation with that office. Requests for extensions in excess of these values must be submitted with full justification to the Primary Certification Office (EASA) such that approval, if granted, can be given prior to their use.

A. CMRs controlled by Flight Hours (FH)

Extensions up to 10% or 500 FH (whichever is the lesser) may exceptionally be granted on CMR intervals quoted in terms of Flight Hours. B. CMRs controlled by Flight Cycles (FC)

Extensions up to 5% or 250 FC (whichever is the lesser) may exceptionally be granted on CMR intervals quoted in terms of Flight Cycles.

C. CMRs controlled by Calendar time (MO)

Where the repeat interval is 12 months or less, extensions up to 10% or 1 month (whichever is the lesser) may exceptionally be granted on CMR intervals quoted in

terms of months. N

### Where the repeat interval is greater than 12 months, extensions up to 2 months may exceptionally be granted.

It is the Operator's responsibility to identify appropriate procedures with the Authority of the State of aircraft registry for the control and development of his maintenance program. This paragraph in the ALS Part 3 is written to confirm to the Authority of the State of aircraft registry that exceptional short-term extensi ons of CMR intervals are permissible. Approval of such extensions rests with the Authority of the State of aircraft registry in the same way as it does for any other scheduled maintenance task interval extension.

and 4. . §2: The sentence “Note: This document is applicable to A319 aircraft used in the corporate role. Since the name ‘A319CJ’ and ‘A319 Co rporate Jet’ are unofficial, CMRs specific to corporate operation are identified with app licability ‘post mod 28238’. This modification introduces provision for more than two additional center tanks and thus identifies aircraft for which a longer flight time is possible. Inte rvals for corporate operation are determined in recognition of a higher average flight time than airline operation.” has been deleted. · §4 Addition of the following sentences “Limit ations of the ALS Part 3 may be negated by instructions given in an Alternative Means Of Co mpliance (AMOC). When limitations evolve in a revision of the ALS Part 3 subsequent to the issuance date of the AMOC, Operators are requested to contact Airbus for guidance.

For these, the safety reason for performing the task is considered to be immediately evident to the Operator and the Au thority of the State of aircraft registry”. · §6.A: The sentence “The tasks and intervals specified in the CMR document are mandatory and cannot be changed, escalated or deleted without the concurrence of the Primary Certification Authority (EASA).” is replaced by “One Star CMRs specified in the ALS Part 3 are mandatory tasks and cannot be changed or deleted without the concurrence of the Primary Certification Authority (EASA). One Star CMR task intervals quoted in ALS Part 3 are absolute limitations and cannot be escalated without the concurrence of the Primary Certification Authority (EASA).”. · §6.B: The sentence “Task intervals may be adjusted in accordance with an operator's approved escalation practices or an approved reliability program, but the task content may not be changed or deleted without prior Primary Certification Authority (EASA) approval.” is replaced by “Two Star CMRs specified in the ALS Part 3 are mandatory tasks and cannot be changed or deleted without the concurrence of the Primary Certification Authority (EASA). Two Star CMR task intervals may be adjusted in accordance with an Operator's approved escalation practices or an approved reliability program, but the task content may not be changed or deleted without prior Primary Certification Authority (EASA) approval.” · §7: Addition of the following sentences “Thi s paragraph provides general rules related to the starting time to be considered for CMR inte rval counting according to the different usage parameters. For CMR tasks whose interval is given in Calendar time, the starting time may be

considered as the date of Transfer of Title to t he first Operator of the aircraft, unless otherwise stated in the delivery documentation of the dedicated aircraft. For CMR tasks whose interval is given in Flight Hours (FH), the starting time may be considered as the date of Transfer of Title to the first Operator of the aircraft, unless other wise stated in the delivery documentation of the dedicated aircraft. Considering the very low num ber of Flight Hours performed between first flight and delivery, and the methodology used to define CMR task intervals, EASA agree to consider the date of delivery of the aircraft as the starting time for CMR tasks whose intervals are given in Flight Hours. For CMR tasks whose interval is given in Flight Cycles (FC), the starting time to be considered is the date of the aircraft first flight, unless otherwise stated in the delivery documentation of the dedicated aircraft.”. · §8: Addition of the definitions of the following terms used in the document: Calendar time (Cal.), Flight Cycle (FC), Flight Hour (FH) , Interval, Operational Check, Functional Check,
