Plain English Summary

3/10 complexity

CASA requires operators of the listed Boeing 767-200, -300 and -300F aeroplanes to modify the aft pitch-load fitting on the nacelle strut diagonal brace, following the technical instructions of FAA AD 2004-01-02 and Boeing Alert Service Bulletin 767-54A0102. The change, effective 18 March 2004, addresses fatigue of a fuse pin that could lead to increased wing-to-strut loads and possible separation of the engine and strut.

Applicability: Model 767-200, -300, and 300F series aircraft, as listed in Boeing Alert Service Bulletin 767-54A0102, dated November 8, 2001.

Requirement: Action in accordance with the technical requirements of FAA AD 2004-01-02 Amdt 39-13415

Compliance: As specified in the Requirement document, with a revised effective date of 18 March 2004

This Airworthiness Directive becomes effective on 18 March 2004.

Background: This Directive requires modification of the aft pitch load fitting of the diagonal brace of the nacelle strut of each wing. This action is necessary to prevent loss of the fuse pin of the pitch load fitting due to fatigue caused by improper clearance between the fuse pin and bushing, which could result in increased loads in the wing-to-strut joints and consequent separation of the strut and engine from the wing.

Signature of David Villiers, Delegate of the Civil Aviation Safety Authority.
