Plain English Summary

4/10 complexity

This Airworthiness Directive requires operators of Boeing 767 aircraft (line numbers 1–62) to carry out inspections and corrective work on the nose wheel well side and top panels by following FAA AD 2002‑12‑05 and Boeing Alert Service Bulletin 767‑53A0090 Rev 1. It responds to reports of broken rivets and the risk of fatigue cracking from pressurisation loads. Operators pay for inspections and repairs; replacing rivets with bolts per Figure 5 ends the repeated inspections. CASA sets the compliance timing (effective 5 September 2002).

AD/B767/176 Nose Wheel Well Side Panels and Top Panel 9/2002

Applicability: Model 767 series aircraft, line number 1 through 62.

Requirement: Action in accordance with the technical requirements of FAA AD 2002-12-05 Amdt 39-12777.

Note: Replacement of all the rivets with bolts in accordance with Figure 5 of Boeing Alert Service Bulletin 767-53A0090 Revision 1, dated 14 September 2000, constitutes terminating action for the repetitive inspection required by paragraph (a) of the Requirement document.

Compliance: As specified in the Requirement document, with a revised effective date of 5 September 2002.

This Airworthiness Directive becomes effective on 5 September 2002.

Background: The manufacturer received a report from an operator of 155 broken rivets found in the left and right nose wheel well side panels and top panel on one aircraft. Analysis indicates that pressurisation loads on the side panel and top panel webs results in high prying loads on the rivets. Continued pressurisation cycles on aircraft with broken rivets could result in the initiation of fatigue cracks.
