## EASA AIRWORTHINESS DIRECTIVE

AD No.: 2014-0071

Date: 19 March 2014

Note: This Airworthiness Directive (AD) is issued b y EASA, acting in accordance with Regulation (EC) No 216/2008 on behalf of the European Communit y, its Member States and of the European third countries that participate in the ac tivities of EASA under Article 66 of that Regulation.

This AD is issued in accordance with EU 748/2012, P art 21.A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the continuing airworthiness of an aircraft shall be en sured by accomplishing any applicable ADs. Conseque ntly, no person may operate an aircraft to which an AD applies, except in accordan ce with the requirements of that AD, unless otherwi se specified by the Agency [EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, A rticle 14(4) exemption].

TCDS Number: EASA.A.182

Foreign AD: Not applicable

Supersedure: This AD supersedes EASA AD 2012-0004 d ated 12 January 2012.

Amendment / Implementation

Manufacturer(s): BAE Systems (Operations) Ltd, Brit ish Aerospace plc, British Aerospace (Commercial Aircraft) Ltd, British Aerospace (Opera tions) Ltd, British Aerospace Regional Aircraft Ltd, British Aerospace Regional Aircraft trading as Avro International Aerospace.

Applicability: BAe 146 and AVRO 146-RJ aeroplanes, all models, all serial numbers.

Reason: The BAe 146 / AVRO 146-RJ Aircraft Maintena nce Manual (AMM) includes the Chapters as listed in Appendix 1 of this AD. Compli ance with these chapters has been identified as a mandatory action for conti nued airworthiness and EASA AD 2012-0004 was issued to require operators t o comply with those instructions. Since that AD was issued, BAE Systems (Operations) Ltd revised the AMM (Revision 107), introducing a new defined life limi t for the Fire Bottle Cartridge Firing Unit into Chapter 05-10-15. Subsequently, Re vision 108 of the AMM introduced in Chapter 05-20-00 inspection tasks for repairs applied to fatigue critical structures and also introduced a new Chapt er 05-20-07 to provide Structural Repair Manual (SRM) references for these tasks, applicable to repairs accomplished after the publication of AMM R evision 108. Finally, AMM Revision 111 introduced safe life limitations into Chapter 05-10-15 for rollers of main landing gear and door up-locks. Furthermore, Section 6 of the Maintenance Review Bo ard Report (MRBR) Document MRB 146-01, Issue 2, Revision 18 was publi shed (as referenced in Chapter 05-20-01 of the AMM) to correct discrepa ncies in inspection tasks for a number of Structurally Important Items (SIIs) .

Failure to comply with the new and more restrictive tasks and limitations referenced above could result in an unsafe conditio n. For the reasons described above, this AD retains th e requirements of EASA AD 2012-0004, which is superseded, and requires imp lementation of the maintenance tasks and/or airworthiness limitations as specified in the defined parts of Chapter 05 of the AMM at Revision 112.

Effective Date: 02 April 2014

Required Action(s) and Compliance Time(s): Required as indicated, unless accomplished previous ly: (1) From the effective date of this AD, accomplish the following actions, in accordance with the instructions as specified (or i ncluded by reference) in the chapters of BAE Systems (Operations) Limited BA e 146 / Avro 146-RJ AMM at Revision 112, as listed in Appendix 1 of this AD. (1.1) Replace each component before exceeding the a pplicable life limit. (1.2) Within the thresholds and intervals, accompli sh all applicable maintenance tasks. (1.3) Ensure the continuing airworthiness of the ae roplane by compliance with each Critical Design Configuration Control Limitations (CDCCL) – Fuel System item. (2) Compliance with the requirements of paragraph ( 1) of this AD can be demonstrated by:
(2.1) Revising as follows the approved Aircraft Mai ntenance Programme (AMP) on the basis of which the operator or the own er ensures the continuing airworthiness of each operated aeroplane : Incorporate all applicable maintenance tasks, airw orthiness limitations and CDCCL – Fuel System items as specif ied (or included by reference) in the chapters of BAE Syste ms (Operations) Limited AMM at Revision 112, as listed in Appendix 1 of this AD,
and (2.2) Complying with the approved AMP described in paragraph (2.1) of this AD.
