Airworthiness Directive · Amendment 39-14114 · 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; as identified in Boeing Alert Service Bulletin 767-26A0119, Revision 1, dated July 15, 2004.
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, and -300F series airplanes. This AD requires installing a new, improved foam seal around certain ducts in the forward cargo compartment. This AD is prompted by the detection of incorrectly installed smoke barrier seals around the electrical/ electronic equipment air supply and exhaust ducts. We are issuing this AD to prevent fire extinguishing agent from leaking out of the seals around the ducts in the forward cargo compartment in the event of an in-flight fire, which could result in failure to extinguish the fire and consequent smoke or fire extinguishing agent entering a compartment occupied by passengers or crew.
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 24 months or 8,000 flight hours after the effective date of this AD, whichever is first: Do the applicable actions required by paragraphs (f)(1) and (f)(2) of this AD by doing all the actions specified in the Accomplishment Instructions of Boeing Alert Service Bulletin 767-26A0119, Revision 1, dated July 15, 2004.
(1) For Group 1 and 2 airplanes: Install a foam seal around the four cooling air supply and exhaust ducts in the electrical/electronic equipment bay in the forward cargo compartment.
(2) For Group 2 airplanes: Install a foam seal around the avionics cooling and refrigeration unit duct in the forward cargo compartment.
Accomplishing the applicable actions before the effective date of this AD in accordance with Boeing Alert Service Bulletin 767-26A0119, dated April 19, 2001, is considered acceptable for compliance with the corresponding actions in paragraph (f)(1) of this AD.
