The NTSB's narrative final · quoted from the NTSB record
The pilot reported that while in cruise flight, the propeller experienced a sudden overspeed. Power was reduced and the pilot turned toward a nearby airport. While on final approach, the engine lost power. The aircraft landed long on the runway and ran off the end and into a swampy area. During the landing roll, the aircraft collided with a tree stump. Inspection of the engine found that the oil pump drive gear separated at its joint with the oil pump drive shaft. A metallurgical examination determined that the shaft for the drive gear showed a shear separation as a result of something forced laterally with respect to its longitudinal axis.
