What happened
The pilot reported that shortly after takeoff, an electrical fire broke out beneath the passenger's seat. The crew initiated an emergency landing procedure to address the immediate threat. Upon landing, the airplane sustained damage. A fire ignited after the aircraft came to rest, resulting in the total destruction of the airframe.
The investigation
Post-accident examination of the wreckage revealed the root cause of the electrical failure. The airplane had been started using a 24-volt booster instead of the required 12-volt booster. This voltage mismatch caused the wires to melt, leading to a short circuit and the subsequent fire.
Findings
The use of an incorrect 24-volt booster during engine start led to melted wiring. This electrical failure resulted in a fire that destroyed the aircraft.
