NTSB Narrative Summary Released at Completion of Accident

A 652-hour commercial pilot reported a loss of engine power during cruise flight. During a forced landing on a four-lane highway, the airplane collided with a vehicle. Examination of the engine revealed that the #2 cylinder head was fractured circumferentially between that fourth and fifth fins from the engine end of the head due to fatigue. As a result, the head was in two pieces: the engine side and the dome side. The engine side of the head remained attached to the barrel and the injector line was fractured at one of the brazed joint for one of the ferrules. The 215-horsepower engine had accumulated a total 326-hours since the last top overhaul and 887 hours since its last major overhaul.

NTSB Probable Cause Narrative

The loss of engine power due to the fatigue fracture of the #2 cylinder head. A contributing factor was the lack of suitable terrain for the forced landing.
