Airworthiness Directive · Amendment 39-14037 · Boeing Model 767-300 and -400ER Series Airplanes
Boeing Model 767-300 and -400ER Series Airplanes
This AD applies to Boeing Model 767-300 series airplanes as listed in Boeing Special Attention Service Bulletin 767-21-0188, dated May 27, 2004; and Boeing Model 767-400ER series airplanes, as listed in Boeing Special Attention Service Bulletin 767-21-0189, dated May 27, 2004; certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767-300 and -400ER series airplanes. This AD requires replacing the in-flight entertainment cooling card, located in the P50 card file in the main equipment center, with a new, improved cooling card. This AD is prompted by a report of an improperly designed component on the in-flight entertainment (IFE) cooling card, which may cause the IFE cooling system to incorrectly interpret signals from airplane system interfaces. We are issuing this AD to prevent failure of the IFE cooling card to configure itself correctly in response to input signals from airplane system interfaces during a forward cargo fire, which could result in the IFE cooling fan causing smoke to penetrate occupied areas of the airplane.
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 18 months after the effective date of this AD: Replace the IFE cooling card, part number (P/N) 285T1198-101, located in the P50 card file in the main equipment center, with a new, improved cooling card, P/N 285T1198-102. Do the replacement by accomplishing all of the actions specified in the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767-21-0189 (for Boeing Model 767-400ER series airplanes); or 767-21-0189 (for Boeing Model 767-400ER series airplanes); both dated May 27, 2004; as applicable. Where the service bulletins state that the replacement may be done using an “operator's equivalent procedure,” the replacement must be done according to the procedures in the chapter/subject of the applicable Boeing 767 Airplane Maintenance Manual specified in the service bulletins.
As of the effective date of this AD, no person may install an IFE cooling card, P/N 285T1198-101, on any airplane.
