The pilot reported that while he was pulling up out of a field and starting into a turn, he heard a loud bang and felt an abrupt reduction of power. During the emergency landing the airplane nosed over. The pilot reported that the entire propeller assembly was missing and that it had broken off at the crankshaft flange. A propeller blade was found over a month later. An examination of the blade revealed that it had broken off at the blade root. The pilot reported that the propeller had been leaking oil. He had sent the propeller to a propeller shop to have it inspected for leaks and cracks. He reported that the propeller shop's examination found no cracks and replaced the seals. The pilot reported that the propeller was returned to service, but after seven hours of flight the propeller failed. A metallurgical laboratory reported that, 'the propeller failed with a transverse fracture in the threads at the base of the blade.'
Probable Cause: a fatigue failure of the propeller blade, and inadequate maintenance inspection performed by the propeller shop.
