Applicability: Model 727 equipped with a main deck class B cargo compartment with a volume exceeding 5.66 cubic metres (200 cubic feet). Requirement: Action IAW the technical requirements of FAA AD 93-07-15 Amdt 39-8547. However, for the carriage of livestock, an alternative configuration which establishes an equivalent level of safety would be acceptable to the authority. Compliance: As specified in the Requirement Document with a revised effective date 22 July 1993 for Australian registered aircraft.

Note: The compliance date of this airworthiness directive remains unchanged by this amendment. This Amendment becomes effective on 29 September 2006. Background: Following the loss of a Boeing model 747-200 "Combi" aircraft that developed a major fire on the main deck cargo compartment, the FAA carried out an evaluation of fire protection requirements of such aircraft. The conclusion indicated that the fire protection requirements for Class B cargo compartments are inadequate.
