AD/HS 748/29 Nose Landing Gear 6/2002

Applicability: All HS748 series aircraft.

Requirement: Action in accordance with BAE Systems Mandatory Service Bulletin HS748-32-104. Compliance: At the next scheduled nose landing gear removal after 13 June 2002 or before 31 July

2005, whichever occurs first.

This Airworthiness Directive becomes effective on 13 June 2002.

Background: Failure to observe instructions for installing the nose landing gear can result in incorrect assembly. This may result in the pintle pin being unlocked so that it is free to migrate from its support housing, which may eventually lead to jamming or collapse of the gear. An additional baulking device is introduced to provide further confirmation that the pintle pin has been correctly installed.
