What happened
During a flight at an altitude of approximately 150 meters, the aircraft experienced a sudden loss of engine power. Although the pilot managed to successfully restart the engine, the plane could not maintain its altitude. The aircraft type descended into a forested region in Sikmarö, striking trees before coming to a complete stop. The impact resulted in the total destruction of the airframe. There were four injuries reported among the occupants, consisting of the pilot, a signaller, and two passengers.
Findings
Investigations into the accident revealed that the engine failure was a direct result of fuel exhaustion. While the aircraft still possessed adequate fuel in a secondary tank, the fuel selector valve had been left connected to an empty tank. The investigation concluded that the pilot failed to switch the fuel selector to the remaining fuel source in a timely manner.
