Circumstances:
On short final in strong crosswinds, the airplane stalled and crashed within the runway threshold. There were no casualties but the aircraft was damaged beyond repair. It was reported that the fuel selector was positioned to the lower tank, which prevented the fuel to reach the engine because of the position of the aircraft on final approach.

Special thanks to Claude Rouge who shared the photos and personnel logbook from his father Frédy Rouge who was in charge of HB-FAX at that time.
