STILL MICHAEL J TITAN T-51
The pilot reported that, while on final approach, after passing over the airport perimeter fence, the engine lost power. The airplane had a high descent rate, impacted the ground about 100 ft from the approach end of the runway, and slid to a stop about 3 ft from the runway threshold. Postaccident examination revealed 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 contacted the engine control unit (ECU) toggle switch while he was positioning the flaps, which shut down the engine. 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 preaccident mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
