EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2013-0206 

Date: 09 September 2013 

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 EU 748/2012, Part 21.A.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]. 

Design Approval Holder’s Name: 

BAE SYSTEMS (OPERATIONS) LTD 

Type/Model designation(s): 

Jetstream Series 3100 and 3200 

aeroplanes

TCDS Number: EASA.A.191 

Foreign AD: Not applicable 

Supersedure: None 

ATA 32 Landing Gear – Main Landing Gear – Modification 

Manufacturer(s): British Aerospace PLC, British Aerospace (Commercial Aircraft) Ltd, British 

Aerospace Regional Aircraft Ltd, Jetstream Aircraft Ltd and British Aerospace 

(Operations) Ltd. 

Applicability: Jetstream Series 3100 and 3200 aeroplanes, all models, all serial numbers. 

Reason: An occurrence of Jetstream 3100 main landing gear (MLG) failure after landing 

was reported. The subsequent investigation revealed stress corrosion cracking 

of the MLG yoke pintle housing as a root cause of the MLG failure. Degradation 

of the surface protection by abrasion can occur when the forward face of the 

yoke pintle rotates against the pintle bearing, which introduces corrosion pits 

and, consequently, stress corrosion cracking. 

This condition, if not corrected, could lead to structural failure of the MLG 

possibly resulting in loss of control of the aeroplane during take-off or landing 

runs. 

To address this potential unsafe condition, BAE Systems (Operations) Ltd 

issued Service Bulletin (SB) 32-JM7862 to provide instruction for installation of 

a protective washer fitted at the forward spigot on both, left hand (LH) and right 

hand (RH), MLG. 

For the reasons described above, this AD requires installation of a washer to 

protect the MLG at the forward face of the yoke pintle.
