Boeing 767 Series Aeroplanes

AD/B767/201 Amdt 2 Body Station 955 Fail-Safe Straps 2/2009

Applicability:

Model 767-200, -300, and -300F series aircraft, line numbers 1 through 931.

Requirement:

Action in accordance with the technical requirements of FAA AD 2004-19-06 R1 Amdt 39-14313.

Corrective actions (repairs or repeat inspections) that are approved on an FAA form 8100-9 and approved by the Manager, Seattle Aircraft Certification Office or delegate as an Alternative Method of Compliance (AMOC) to the requirements of FAA AD 2004-19-06 R1, may be carried out without the need to obtain an exclusion from CASA from this airworthiness directive.

Note:  Boeing Service Bulletin 767-53A0100 original issue, or later FAA approved revision, refer.

Compliance:

As specified in the Requirement document.

This Amendment becomes effective on 12 February 2009.

Background:

The FAA received several reports of cracking in the fail-safe straps between the side fitting of the rear spar bulkhead at Body Station 955 and the fuselage skin.  Undetected fatigue cracking or corrosion of the fail-safe straps could result in cracking of adjacent structure and consequent reduced structural integrity of the fuselage.

Amendment 1, effective 22 December 2005, was issued in response to a revision of the related FAA AD, which revised applicability to reduce the number of affected aircraft.

This amendment allows the use of an FAA approved Alternative Method of Compliance (AMOC) to the requirements of this AD, without the need for the operator to continually apply for an exclusion for repairs that are already approved on a form 8100-9 as an AMOC by an FAA delegate.

The original issue of this AD became effective 25 November 2004.
