COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Image unavailable in extracted text
Boeing 727 Series Aeroplanes
AD/B727/139 Cargo Door Latch Lockpin 3/92
Applicability: Model 727 and 727-100 series; equipped with a main cargo door installed in accordance with STC SA 1368 SO.
Requirement: Action IAW the technical requirements of FAA AD 92-02-03 Amdt 39-8139. Compliance: As specified in the Requirement Document with a revised effective date of 6 March
Background: This Directive is prompted by the results of an FAA audit of the cargo door installation which revealed that a revision to the STC allowed for as many as three cargo door latch lockpins to be inoperative during flight. The actions specified in this AD are intended to prevent an inadvertent in-flight opening of the main deck cargo door, with resultant major structural damage and possible reduced controllability of the aircraft. The effective date required by the FAA is extended approximately two months.
