Incident Sequence
While en route from Munich to Geneva at cruising altitude, the left engine of the aircraft suddenly failed. Within seconds, the right engine lost power and subsequently failed as well. The crew declared an emergency and was granted clearance to divert to Friedrichshafen Airport.
On short final approach to runway 06, the aircraft's airspeed dropped to a critically low level, causing it to stall. The aircraft then impacted a parking lot approximately 200 meters short of the runway threshold. The impact destroyed the aircraft.
Injuries and Damage
All four occupants sustained injuries. The two passengers were seriously wounded. The copilot suffered a broken foot, while the captain escaped without injury.
Probable Cause
The official investigation determined that the engine failure was a consequence of carburetor icing.
