NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The airplane was damaged when it impacted trees and a house during a forced landing following a loss of engine power. The pilot reported losing engine power while climbing through 4,200 feet. He reported that the engine was set to 2,500 rpm during the climb, and after hearing a loud noise from the engine, the tachometer read about 1,200 rpm. He stated that the engine was running rough and would only achieve 1,500 to 1,900 rpm at full throttle. He diverted to a nearby airport and executed a forced landing. During the landing, he realized he would not be able to stop before impacting trees at the end of the runway. The pilot then attempted to clear the trees at the end of the runway and land in a clearing on the opposite side. He stated that after clearing the trees, the airspeed started to fall rapidly and the airplane struck trees and came to rest on the roof of a house that he had not seen. Subsequent to the accident, the number four exhaust valve was found to be fractured.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The loss of engine power due to failure of the engine exhaust valve. The pilot's inability to maintain clearance from obstacles, the trees, the residence and the pilot's evasive maneuver were factors in the accident.
