      2. Perform inspections of the parts listed in Table 1 of this AD in accordance with the instructions provided in the applicable manual provisions.

      Definition:

   For the purposes of these mandatory inspections, piece-part opportunity means:

        a) The part is considered completely disassembled when accomplished in accordance with the disassembly instructions in the manufacturer's engine manual; and

        b) The part has accumulated more than 100 cycles-in-service since the last piece-part opportunity inspection, provided that the part was not damaged or related to the cause for its removal from the engine.

      The parts
