Compliance required as indicated.
As a result of several propeller blade failures the following inspections are required:

If no cracks are found blades may be returned to service. Any blades showing evidence of cracks are not eligible for repair and shall not be used again in certificated aircraft.
The repetitive inspections required on Pratt and Whitney R-985 engines in this AD are no longer necessary when the engine crankshaft flyweight and flyweight liners have been reworked or replaced at each overhaul period as detailed in AD 65-07-02.
