SHORTLY AFTER TAKEOFF, AS THE AIRPLANE REACHED ITS ASSIGNED CRUISE ALTITUDE, THE AIRPLANE'S ENGINE LOST TOTAL POWER. THE PILOT MADE A FORCED LANDING IN A FIELD AND DURING THE ROLLOUT COLLIDED WITH A TREE AND DITCH. POSTACCIDENT EXAMINATION OF THE ENGINE REVEALED THAT FIVE OF SIX HYDRAULIC TAPPET BODY HEADS WERE SEPARATED FROM THE TAPPET BODY. THE TAPPET HEADS WERE FOUND THROUGHOUT THE ENGINE CASE. THE REASON FOR THE TAPPET BODY HEAD FAILURES WAS NOT DETERMINED.
Probable Cause: the loss of engine power due to failure of the engine's hydraulic tappet body heads. Related factors in the accident were the restricted visual lookout, and the unsuitable terrain encountered during the forced landing.
