Amdt 1

Inboard Trailing Edge Flaps Collar Fittings 11/2003

Applicability: Model 767 series aircraft, with line numbers 1 through 749.

Requirement: Action in accordance with the technical requirements of FAA AD 2003-14-09 Amdt 39-13228.

Note: Boeing Alert Service Bulletins 767-57A0066 Revision 1 and 767-57A0066 Revision 3 including Appendices A and B, refer.

Compliance: As specified in the Requirement document, with a revised effective date of 30 October 2003.

This Amendment becomes effective on 30 October 2003.

Background: The FAA received a report of a complete fracture of an inboard trailing edge flap collar fitting as a result of stress corrosion cracking. The actions required by this Directive are intended to prevent separation of the inboard trailing edge flap from the wing due to fractured collar fittings.

Amendment 1 is issued in response to a new FAA AD which expands applicability, and adds repetitive inspections of the collar fittings, torque tube, and splined bushings of both inboard trailing edge flaps. It also provides follow-on and corrective actions, if necessary.

The original issue of the Airworthiness Directive became effective on 25 February 1999.

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