Event Location
Probable Cause
The pilot's inadvertent contact with the engine control unit toggle switch during flight, which resulted in the engine shutting down.
Full Narrative
The pilot reported that while on final approach, after passing over the airport perimeter fence, the engine lost power. The airplane had a high rate of descent, impacted the ground about 100 ft from the approach end of the runway, and slid to a stop about three feet from the runway threshold.
During the postaccident examination, it was found that the instrument panel layout had the flap position buttons adjacent to the unguarded engine control switches. The pilot reported that while on final approach, he inadvertently made contact with the engine control unit (ECU) toggle switch while he was positioning the flaps, which shut the engine down. Engine download data indicated that the ECU was turned off while on short final.
The fuselage and inboard wing spar structure were substantially damaged.
The pilot reported that there were no pre-accident mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
