Incident Overview
A flight from Colmar to Zurich, with an intermediate stop in Basel, was concluding with a night approach to runway 28 at Zurich-Kloten Airport. As the aircraft descended, both engines lost power simultaneously. Losing altitude, the aircraft struck a three-floor building and subsequently crashed onto a second building located several dozen meters further.
Injuries and Damage
The captain sustained serious injuries, while the copilot was killed in the accident. The aircraft was destroyed upon impact with the buildings.
Probable Cause
The official investigation determined the accident resulted from a combination of factors: insufficient flight preparation, an insufficient fuel supply, and an emergency landing at night in a densely populated area following a double engine failure caused by inappropriate operation of the fuel selector switch.
