| Phase: | Take off |
| Nature: | Private |
| Departure airport: | Helena, MT (HLN) |
| Missoula, MT (MSO) | |
| Investigating agency: | NTSB |
| Confidence Rating: |  Accident investigation report completed and information captured |
The private pilot reported that a preflight inspection and engine run-up revealed no anomalies; however, during the initial climb after takeoff, the engine was not developing full power. The pilot initiated a shallow left turn back to the runway, but the airplane was not able to maintain altitude or airspeed and subsequently impacted a house.
A postaccident examination of the airframe and engine did not reveal any mechanical anomalies that would have precluded normal operation, and the reason for the loss of engine power could not be determined.
Probable Cause: Loss of engine power after takeoff for reasons that could not be determined because postaccident examination did not reveal any evidence of an anomaly that would have precluded normal operation.
