Piper PA-28-161 Cherokee Warrior II, G-BYKR
The aircraft suffered a loss of engine power shortly after takeoff but the instructor pilot was able to land back on the runway. However, there was insufficient distance available in which to stop and the aircraft overran the end of the paved surface and passed through the airport boundary fence, coming to rest inverted on a public road. Although it was substantially damaged and leaking fuel, there was no fire. Examination and testing of the engine and other components did not identify any defects that could have accounted for the loss of engine power.
