Narrative:THIRTY FIVE MINUTES INTO THE DARK NIGHT VMC FLIGHT, THE ENGINE SEIZED WITH NO WARNING. THE PILOT EXECUTED A FORCED LANDING TO A GOLF COURSE AND IMPACTED A TREE JUST BEFORE LANDING. ENGINE TEARDOWN DISCLOSED THAT THE BEARING INSIDE THE GEAR AND SPRAG HOUSING WAS MISSING A NEEDLE AND WAS LOCKED IN POSITION ON THE STARTER GEAR AND SHAFT ASSEMBLY. THE MISSING NEEDLE WAS NOT FOUND. THE GEAR AND SPRAG HOUSING WOULD NOT ROTATE IN EITHER DIRECTION ON THE SHAFT ASSEMBLY. THIS RESULTED IN THE ENGINE BACK DRIVING THE STARTER.
