Airworthiness Directives; The Boeing Company Model 767-200, -300, -300F, and -400ER Series Airplanes

What this AD requires

We are superseding an existing airworthiness directive (AD) that applies to The Boeing Company Model 767-200, -300, and -300F series airplanes. That AD currently requires inspections to detect cracking or corrosion of the fail-safe straps between the side fitting of the rear spar bulkhead at body station 955 and the skin; and follow- on and corrective actions. This new AD expands the applicability; and adds an inspection for cracking in the fail-safe strap, and repair or replacement if necessary. This AD was prompted by additional reports of cracks in 51 fail-safe straps on 41 airplanes; we have also received a report of a crack found in the "T" fitting that connects the fail- safe strap to the outboard edge of the pressure deck. We are issuing this AD to detect and correct fatigue cracking or corrosion of the fail-safe straps and the "T" fittings, which could result in cracking of adjacent structure and consequent reduced structural integrity of the fuselage.

Applies to airplanes identified in Boeing Service Bulletin 767-53A0100, Revision 3, dated February 6, 2012. Airplanes with STC ST01920SE installed do not require a 'change in product' AMOC approval request; all other AMOC requests require approval per paragraph (o) of this AD.

Whether AD 2012-09-04 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 2012-09-04 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
