                     Model                                                                                                                                                                                                                                                                                                                                                                                                                                               Special Attention Service Bulletin
                     767-300                                                                                                                                                                                                                                                                                                                                                                                                                                         767-21-0188 dated 27 May 2004
                    767-400ER                                                                                                                                                                                                                                                                                                                                                                                                                                        767-21-0189 dated 27 May 2004
Requirement:       1. Replace the in-flight entertainment (IFE) cooling card, part number (P/N) 285T1198-101, located in the P50 card file in the main equipment centre, with a new, improved cooling card, P/N 285T1198-102 in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767-21-0188 (for Boeing Model 767-300 series aeroplanes) or 767-21-0189 (for Boeing Model 767-400ER series aeroplanes); 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 Aeroplane Maintenance Manual specified in the service bulletins.
                   2. IFE cooling card, P/N 285T1198-101, may not be installed on any aeroplane as a replacement spare.
                Note:  FAA AD 2005-07-13 Amdt 39-14037 refers.
Compliance:     For Requirement 1 - Within 18 months after the effective date of this Directive.
                For Requirement 2 - As of the effective date of this Directive.
                This Airworthiness Directive becomes effective on 9 June 2005.
Background:     The United States Federal Aviation Administration (FAA) has received a report that an improperly designed component on the IFE cooling card may cause the IFE cooling system to incorrectly interpret signals from aeroplane system interfaces.

   This Directive requires replacement of the cooling card and limits the installation of the card as a replacement spare.  These measures are designed to prevent failure of the IFE cooling card to configure correctly in response to input signals from aeroplane system interfaces during a forward cargo fire, which could result in the IFE cooling fan causing smoke to penetrate occupied areas of the aeroplane.
