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

What this AD requires

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 767-200, -300, and -400ER series airplanes. That AD currently requires an inspection to determine if the door-mounted escape slide/rafts have certain part numbers. This new AD does not retain that requirement. This new AD continues to require an inspection for excessive tension of the firing cable, and procedures for providing slack in the firing cable or rerouting the firing cable if necessary. For certain airplanes, this new AD also requires a review of the airplane maintenance records to determine if a certain service bulletin has been incorporated, or an inspection to determine if certain door-mounted escape slide/rafts are installed. This new AD also requires modification of certain escape slide/rafts. This AD results from reports of uncommanded inflation inside the airplane of a door-mounted escape slide/raft located in the passenger compartment. We are issuing this AD to prevent injury to maintenance personnel, passengers, and crew during otherwise normal operating conditions and to prevent interference with evacuation of the airplane during an emergency, due to uncommanded inflation of a door-mounted escape slide/raft.

Applies only to airplanes identified in Boeing Alert Service Bulletin 767-25A0395, Revision 1, dated January 25, 2007, that are equipped with Goodrich door-mounted escape slide/rafts having the listed part numbers.

Whether AD 2008-21-05 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2008-21-05 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.
