Circumstances:
On final approach to Moscow-Vnukovo, the flying crew was not concentrated and failed to lower the landing gear. The aircraft belly landed and slid for dozen yards before coming to rest in flames. Forty people were uninjured, 46 were wounded and 16 passengers were killed after the aircraft caught fire due to hydraulic leak and an electrical short-circuit in the cargo compartment.
Probable cause:
It was determined that the crew failed to follow the approach checklist and forgot to lower the undercarriage. The following factors were considered as contributing:
- Several propeller blades detached while contacting the runway surface, causing severe damage to the fuselage,
- A fire erupted following an electrical short-circuit in the cargo hold combined with a hydraulic leak,
- Lack of coordination on part of the cabin crew who failed to follow the safety and evacuation procedures,
- Lack of efficiency and assistance on part of the ground firefighters who arrived on the scene 15-20 minutes after the accident.
