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.

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.

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.
