Probable cause
The loss of engine power for reasons that could not be determined because postaccident examination of the airframe and engine did not reveal any anomalies that would have precluded normal operation.
NTSB analysis
The pilot reported that the airplane's engine stopped producing power during climb after takeoff. The airplane impacted terrain as the pilot was attempting to avoid a house during the forced landing. A postaccident examination of the airplane confirmed crankshaft and accessory system continuity. The magnetos and fuel system could not be tested due to impact damage. No preimpact anomalies were noted during the examination that would explain the loss of engine power.
