A.This section gives the mandatory inspections for engine parts.
2 . Mandatory Inspection.
Subtask 05-21-00-280-001
A.You must do a fluorescent-penetrant inspection and an eddy current inspection of the parts that follow. Do the inspection as specified in the piece part sections of the engine manual at each piece part exposure. Piece part exposure is defined as follows:
(1)The part is completely disassembled as specified in the disassembly instructions in the engine manual.
(2)The part has a total of more than 100 cycles in service since the last piece part inspection, if the part was not damaged or related to the cause for its removal from the engine.
(3)The following service bulletins allow for mandatory inspections to be waived on certain components during a quick turn shop visit. Refer to TASK 72-00-00-200-805 (72-00-00, INSPECTION 001), Subtask 72-00-00-220-051, and the service bulletins listed below for details:
