Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 767-300 and -400ER series airplanes. This proposed AD would require 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 proposed 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 proposing 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.
