AD/B747/90 Amendment 1 requires operators of certain Boeing 747 series aircraft (those listed in Boeing Service Bulletin 747‑57‑2256 Revision 3) to carry out the inspections and corrective actions specified in FAA AD 2002‑23‑21 for trailing‑edge flap track bolt holes.

Amdt 1

Trailing Edge Flap Track 3/2003

Applicability: Model 747 series aircraft, as listed in Boeing Service Bulletin 747-57-2256 Revision 3, dated 21 June 2001.

Requirement: Action in accordance with the technical requirements of FAA AD 2002-23-21 Amdt 39-12965.

Note: Boeing Service Bulletins 747-57-2256, 747-57-2256 Revision 1, 747-57-2256

Revision 2, and 747-57-2256 Revision 3 refer.

Compliance: As specified in the Requirement document, with a revised effective date of 20 March 2003.

This Amendment becomes effective on 20 March 2003.

Background: The FAA received reports of missing cadmium plating, and corrosion in certain flap track fail-safe bar bolt holes. This condition, if not corrected, could result in fracture of the trailing edge flap track, separation of the flap supported by the track, and consequent reduction in controllability of the aircraft.

Amendment 1 is issued in response to a new FAA AD which was prompted by reports of corrosion and cracks found in certain bolt holes reworked to the requirements of the original issue of this Directive (existing FAA AD).

The original issue of this Airworthiness Directive became effective on 18 April 1991.

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