Incident Details
While descending to Zurich-Kloten Airport, the flight engineer encountered technical issues with the cabin pressure and was forced to control it manually. Focused on this problem, he failed to hear and understand the captain's instruction to lower the landing gear. In such circumstances, the aircraft landed on its belly on runway 16.
After touchdown, the airplane slid for 875 meters before coming to rest. It subsequently burst into flames.
Evacuation and Damage
All 20 occupants were quickly evacuated and uninjured. The aircraft, however, was damaged beyond repair.
Investigation revealed that the crew failed to hear the gear alarm.
Probable Cause
The official finding stated that the belly landing was caused by a crew error. The following factors were considered as contributing: poor planned approach, lack of crew coordination, and lack of crew concentration.
