Sub-part 3-0 INTRODUCTION

From revision 16 and on, the content of

A340 Certification Maintenance Requirements (CMR) Document (Referenced 955.3019/92)

applicable to A340 models, has been transferred to the

A340 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-al one documents in a location dedicated to the

limitations.

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

1. SCOPE

Though not addressed by the paragraph 25.4 of Joint Aviation Requirements (JAR) 25 appendix H, CMR’s 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 constitute s 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 ag reed with the Authority of the State of aircraft registry.

This document is applicable from first delive ry of an aircraft configuration into an Operator’s fleet. The starting ti mes for CMR task intervals are defined in para 6 of this

sub-section. Possible interval escalations mu st be justified in accordance with the procedure given in paragraph 5 of this sub-section. If a more restrictive CMR is issued on an aircraft configuration already in ser vice, the requirement for existing Operators

to follow the revised ALS Part 3 will normall y be mandated by Airworthiness Directive (AD).

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

Airworthiness Directives dedicated to specific 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 th e State of aircraft registry.

### AIRWORTHINESS LIMITATIONS SECTION

2. APPLICABILITY

The document covers the following A340 models:

A340-211 A340-311 A340-541 A340-642

A340-212 A340-312 A340-542 A340-643

A340-213 A340-313

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

The CMR’s contained in the ALS Part 3 are valid up to the following Limit of Validity (LOV):

Aircraft & Weight Variant (WV) Series Flight Hours (FH)

A340-200 series 80 000FH

A340-300 series excl. WV050’s 80 000FH

A340-300 series WV050’s 100 000 FH

A340-500 series 100 000 FH

A340-600 series 100 000 FH

Note: MOD 49144 is used to identify WV050 serie s aircraft since this modification cannot be retrofitted on WV000, WV010 and WV020 series aircraft.

3. ALTERNATIVE MEANS OF COMPLIANCE

Limitations of the ALS Part 3 may be negated by in structions given in an Alternative Means Of Compliance (AMOC). When limitations evolve in a revision of the ALS Part 3 subsequent to the issuance date of the AMOC, Operators ar e requested to contact Airbus for guidance.

It is Operator’s responsibility to refer to the applicable limitations.

4. CRITERIA FOR IDENTIFICATION

CMRs are tasks arising from the Type Certifi cation 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 CMR’s:

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

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

− 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 Stat e of aircraft registry.

5. HANDLING OF CERTIFICAT ION 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 t he Primary Certification Authority (EASA). One Star CMR task intervals quoted in ALS Pa rt 3 are absolute limitations and cannot be

escalated without the concurrence of the Pr imary 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 t he 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 progra m make adjustments to their maintenance programs based on data collection and analyti cal techniques. It has been demonstrated that the use of such methods to manage a maintenance program does not give rise to

undue escalation.

6. 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 docum entation of the dedicated aircraft.

For CMR tasks whose interval is given in F light 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 docum entation of the dedicated aircraft. Considering the very low number 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 F light Cycles (FC), the starting time to be

considered is the date of the aircraft first fl ight, unless otherwise stated in the delivery

documentation of the dedicated aircraft.

7. DEFINITIONS

Calendar time (Cal.): Thresholds/interval s 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 qualit ative 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 det ermine 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.

8. EXCEPTIONAL SHORT-TERM EXTENSIONS

Since CMR intervals are based on statistical averages and reli ability rates, an exceptional short-term extension for a specific CMR interval 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-te rm extensions must

not be used for fleet CMR escalation.

Unless noted adjacent to the task, for all CM Rs (One Star and Two Star) identified in this ALS Part 3, it has been accepted by the Primary Certification Office (EA SA) 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. CMR’s controlled by Flight Hours (FH)

Extensions up to 10% or 500 FH (whi chever is the lesser) may exceptionally be granted on CMR intervals quoted in terms of Flight Hours.

B. CMR’s controlled by Flight Cycles (FC)

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

C. CMR’s 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 responsib ility to identify appropria te procedures with the Authority of the State of aircraft registry for the contro l 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 extensio ns of CMR intervals are permissible. Approval of such extensions rests with the Authority of t he State of aircraft registry in the same way as it does for any other scheduled maintenance task interval extension
