Summary
While cruising at 2500 feet in visual conditions, the propeller suddenly detached from the engine. Because his radio had not been working well, the pilot quickly made an emergency call from his mobile telephone to the police emergency number. He then concentrated on making a forced landing onto a country road. During the landing roll, the aircraft hit a dirt bank which resulted in substantial damage. An inspection of the aircraft after the accident revealed a broken crankshaft which was the reason the propeller had detached from the engine.
