### Type Approval Holder’s Name : BAE Systems (Operations) Ltd Type/Model designation(s) : BAe 146 and AVRO 146-RJ aeroplanes

TCDS Number : EASA.A.182

Foreign AD : Not applicable

Supersedure : This AD supersedes EASA AD 2009-0020 dated 05 February 2009.



### ATA 05 Time Limits / Maintenance Checks – Airworthiness Limitations – Implementation

Manufacturer(s): BAE Systems (Operations) Ltd, Britis h Aerospace plc, British Aerospace (Commercial Aircraft) Ltd, British Aerospace (Operations) Ltd, British Aerospace Regional Aircraft Ltd, Britis h Aerospace Regional Aircraft trading as Avro International Aerospace.
Applicability: BAe 146 and AVRO 146-RJ aeroplan es, all models, all serial numbers.

Reason: The BAe 146 / AVRO 146-RJ Aircraft Maintenance Manual (AMM) includes Chapters 05-10 “Time Limits”, 05-15 “C ritical Design Configuration Control Limitations (CDCCL) - Fuel System Description and Operation” and 05-20 “Scheduled Maintenance Checks”, some sub-chapters of which have been identified as requireme nts for continued airw orthiness and EASA AD 2009- 0020 was issued to require operators to comply with those instructions. Since the issuance of that AD, BAE Systems (Operati ons) Limited has amended the AMM to introduce life limitations on additional main landing gear shock absorber inner and outer cylinder and bolt part numbers in sub-chapter 05-10-15. In addition BAE Systems has updated and clarified the text in subchapters 05-00-00, 05-10-01, 05-20-00, 05-20-01 and 05-20-10 and changed the modification effectivity status in sub-chapters 05-10-05, 05-10-10 and 05- 20-10. Finally BAE Systems has introduce d a new sub-chapter, 05-20-05, to define the maintenance for aeroplanes in the Life Extension Programme (LEP) which have had their landings life extended. For the reasons described above, this EASA AD retains the requirements of EASA AD 2009-0020, which is superseded, and requires the implementation of the instructions, limitations, inspections and corrective measures as specified in the defined parts of Chapter 05 of the AMM at Revision 96.EASA AD No.: 2009-0215
