Plain English Summary

4/10 complexity

This directive requires operators of Boeing 767 aircraft (line numbers 1–879) to follow FAA AD 2003-11-16: carry out a one‑time inspection of the inboard main flap aft support bolts, perform any corrective actions found, and replace existing titanium bolts with steel bolts (Requirement; Background). CASA revoked the earlier AD and set compliance timing and the effective date. The practical effect is an enforced inspection, repair and parts‑replacement program that aircraft operators must fund and schedule under CASA’s instruction.

Amdt 1

Inboard Main Flap Support Bolts 9/2003

Applicability: Model 767 series aircraft, including Model 767-400ER aircraft; line numbers 1 through 879.

Requirement: Action in accordance with the technical requirements of FAA AD 2003-11-16 Amdt 39-13175.

Note: Boeing Alert Service Bulletin 767-27A0176 Revision 1 refers.

Compliance: As specified in the Requirement document, with a revised effective date of 4 September 2003.

This Amendment becomes effective on 4 September 2003.

Background: The FAA received a report indicating that an operator found one missing bolt and two loose bolts out of four bolts at the aft attachment locations on the outboard support of the inboard main flap on a B767 series aircraft. There was evidence that the bolts were not installed tightly, though when the improper installation occurred has not been determined. The outboard support for the inboard main flap cannot carry limit load with one bolt missing in the aft attachment locations. Missing, loose, or cracked bolts at this location, if not detected, could lead to loss of the inboard main flap.

Amendment 1 is issued in response to a new FAA AD, which requires a new one- time inspection and check, corrective actions if necessary, and eventual replacement of existing titanium bolts with steel bolts.

The original issue of this Airworthiness Directive became effective on 26 December 2002.

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