### Sub-part 3-0 INTRODUCTION

From revision 20 and on, the content of

A330 Certification Maintenance Requirements (CMR) Document (Referenced 955.2074/93)

applicable to A330 models, has been transferred to the

A330 Airworthiness 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 times for CMR task intervals are defined in paragraph 8 of this sub-section. Possible interval escalations must be justified in accordance with the procedure given in paragraph 7 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. R

### 2. APPLICABILITY

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

A330-201 A330-301

A330-202 A330-302

A330-203 A330-303

A330-223 A330-321

A330-243 A330-322

A330-223F A330-323

A330-243F A330-341

A330-342

A330-343

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

3. A330 AICRAFT SYSTEMS UTILISATION

The CMRs contained in the ALS Part 3 are valid up to the limitations published in this document which have been identified in consideration of a maximum number of Flight Hours (FH) that may be accrued by an individual aircraft, as follows:

Aircraft Series Flight Hours (FH)

R A330-200 series PRE 49144 PRE 200103 0 60000 FH

R A330-200 series PRE 49144 POST 200103 100000 FH

R A330-200 series POST 49144 100000 FH

R A330-30x series PRE 49144 PRE 58269 0 60000 FH

R A330-30x series PRE 49144 POST 58269 0 80000 FH

R A330-30x series PRE 49144 POST 200103 100000 FH

R A330-32x & A330-34x series PRE 49144 PRE 200103 0 60000 FH

R A330-32x & A330-34x series PRE 49144 POST 200103 100000 FH

R A330-300 series POST 49144 100000 FH

R A330-200F series 100000 FH

Depending on fleet leader operation, the impact of a greater aircraft accumulated FH/FC value may subsequently be investigated and might demonstrate a need for new or revised limitations. As a consequence, should any operator envisage future aircraft operations beyond the quoted values, they must first contact Airbus for advice.

Note:

(1) Within the context of ALS Part 3, MOD 49144 is used to identify WV050 series and WV060 series aircraft (Enhanced aircraft) since this modification cannot be retrofitted on WV000, WV010 and WV020 series aircraft.

(2) MOD 58269 refers to Design Service Goal (DSG) extension of A330-30x (i.e. A330-300 with GE engines) from 60000 FH up to 80000 FH. N

4. MODIFICATIONS/REPAIRS NOT DEVELOPED 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.

5. 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.

6. 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 systems utilisation values in the paragraph 3,

 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.

7. 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). R

R

 AIRBUS SAS 2013. All rights reserved. Confidential and proprietary document. 

### 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). 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.

8. 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.

9. 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.

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. D

### 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 performs within specified limits.

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.

10. EXCEPTIONAL SHORT-TERM EXTENSIONS

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.

### A330 AIRWORTHINESS LIMITATIONS SECTION

ISSUE: AUG 27/13 ALS PART 3-0 PAGE: 6

 AIRBUS SAS 2013. All rights reserved. Confidential and proprietary document. 

### 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. 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

 Following wording modifications have been performed:

 From revision 20 and on, the content of A330 Certification Maintenance Requirements (CMR) Document (Referenced 955.2074/93) applicable to A330 models, has been transferred to the A330 Ai rworthiness 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 Part 3 has been established with the following

rules:

 §1: Addition of the following sentences:

 “Though not addressed by the paragraph 25.4 of JAR 25 appendix H, CMR’s may be considered as the systems equival ent to the structural Airworthiness Limitation Items. For this reason, it is considered appropriate to identify them as part of the ALS.”.

 “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.”.

 §1: Change “Non-compliance suspends the validity of the Airworthiness Certificate” into “Non-compliance could suspend the validity of the Airworthiness Certificate.”.

 §1: The sentence: “This document does not take into account Airworthiness Directives (Consigne de Navigabilité) which, if issued against a CMR, supersede the specific requirement given in this document.” Has been reworded into “Airworthiness Directives dedicated to specific concerns may override the specific requirement(s) given in this document”.

 §1: “agreed” added in the sentence “The identification of CMR...”.

 §1: “his national authorities” replaced by “the Authority of the State of aircraft registry”.
