EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2010-0166 

Date: 06 August 2010 

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with 

Regulation (EC) No 216/2008 on behalf of the European Community, its Member States and 

of the European third countries that participate in the activities of EASA under Article 66 of 

that Regulation.

This AD is issued in accordance with EC 1702/2003, Part 21A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the 

continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may operate 

an aircraft to which an AD applies, except in accordance with the requirements of that AD, unless otherwise 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, Article 14(4) exemption]. 

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 2009-0215 dated 07 October 2009. 

ATA 05 Time Limits / Maintenance Checks – Airworthiness Limitations – 

Implementation 

Manufacturer(s): BAE Systems (Operations) Ltd, British Aerospace plc, British Aerospace 

(Commercial Aircraft) Ltd, British Aerospace (Operations) 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 Maintenance Manual (AMM) includes 

chapters 05-10 “Time Limits”, 05-15 “Critical 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 requirements for continued airworthiness and AD 2009-0215 

was issued to require operators to comply with those instructions. 

Since the issuance of that AD, BAE Systems (Operations) Limited has 

amended the AMM to remove the life limits on shock absorber assemblies, 

but not the individual shock absorber components, and amend the life limits 

on the different standards of Main Landing Gear (MLG) Up-Locks and MLG 

Door Up-Locks in sub-chapter 05-10-15. In addition BAE Systems has 

amended Chapter 05-10-15 of the AMM to introduce and amend life limits on 

MLG components. 

For the reasons described above, this AD amends the requirements of AD 

2009-0215, 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 100.
