Airworthiness Directive · Amendment 39-14018 · Boeing Model 767-200, -300, and -300F Series Airplanes
Boeing Model 767-200, -300, and -300F Series Airplanes
This AD applies to Boeing Model 767-200, -300, and -300F series airplanes; certificated in any category; equipped with General Electric and Pratt and Whitney engines; as identified in Boeing Service Bulletin 767-54-0107, Revision 1, dated December 18, 2003.
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, and -300F series airplanes. This AD requires replacing the inboard fairing seal common to the vapor barrier seal of each strut assembly. This AD is prompted by discovery during production that a section of vapor barrier seal was missing from the spar web cavities of the upper aft struts of both wings. We are issuing this AD to prevent flammable fluids from leaking onto parts of a hot exhaust system of a shut-down engine of an airplane on the ground, which could result in ignition of the flammable fluids and an uncontained fire. This could also lead to an emergency evacuation of the airplane and possible injury to passengers.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 60 months after the effective date of this AD, replace the inboard fairing seal common to the vapor barrier seal of each strut assembly with a new inboard fairing seal in accordance with the Accomplishment Instructions of Boeing Service Bulletin 767-54-0107, Revision 1, dated December 18, 2003.
Seal installations accomplished in accordance with the Accomplishment Instructions of Boeing Service Bulletin 767-54-0107, dated January 16, 2003, are considered acceptable for compliance with the corresponding action specified in this AD.
