SAAB SF340 Series Aeroplanes
AD/SF340/9
Amdt 1
Power Control Cable 7/88
Applicability: Model SAAB SF340A with power control cables P/No C82146-1 and/or C82146-2 installed.
Requirement: Inspect power control cables in accordance with SAAB Alert Service Bulletin No SF340-76A-024 revision 2.
Note: Swedish AD No 1-024 revision A refers.
Compliance: Unless already accomplished, initially inspect in accordance with the Requirement document and thereafter at intervals not exceeding 200 hours time in service.
Background: The manufacturer has received reports of wear in the two-pin joint of the power control cable and its end pieces, resulting in enlargement of the pin holes which could cause the pins to shear. A possibility then exists that the power lever on the PCU is unintentionally moved into the Beta Range when the power lever in the control quadrant is retarded to flight idle. This amendment is raised because field experience has shown that the original inspection criteria and intervals are not sufficient.
