COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
 SCHEDULE OF AIRWORTHINESS DIRECTIVES

 Fokker F100 (F28 Mk 100) Series Aeroplanes

AD/F100/25 Small Cargo Door Hinge Assembly - 2 4/99

            Applicability:  F.28 Mk.0100, all serial numbers, if equipped with small cargo doors, having hinge assemblies with Part Number (P/N) A28410-405, A28410-407 and/or D28410-409 installed.

             Requirement: 1. Check the aircraft maintenance records and establish the total number of flights for each affected small cargo door hinge assembly, having either P/N A28410-405, A28410-407 or D28410-409.

             2. Perform a detailed inspection of the affected small cargo door hinge assemblies in accordance with the applicable Fokker 70/100 Non-Destructive Testing (NDT) Manual, Part 6, Procedure 52-30-01.

            If cracks are found then repair in accordance with a Fokker developed repair scheme.

            Note: RLD BLA 1996-125/2 refers.

 Compliance: 1. Prior to 22 May 1999.

             2. Inspect before each affected small cargo door hinge assembly accumulates 8,000 flight cycles since new or before 22 May 1999, whichever occurs later.

            Note: If the number of flight cycles cannot be established, then inspect before 22 May 1999.

            Thereafter inspect at intervals not exceeding 8,000 flight cycles.

            All repairs to the cargo door hinge are to be incorporated before further flight. This Airworthiness Directive becomes effective on 22 April 1999.
            Background: During scheduled visual inspections on several F.28 Mk.0100 aircraft, fatigue cracks were found in the hinges of the small cargo doors. These cracks occurred earlier than anticipated. This AD requires the introduction of a repetitive detailed inspection of the affected cargo door hinges.
