Type of aircraft:
Chkalovsky – Abakan – Petropavlovsk-Kamchatsky
Crew on board:
Pax on board:
Few minutes after a night take off from Abakan Airport, while climbing, the aircraft collided with a mountain located 13,4 km from the airfield. The aircraft was totally destroyed upon impact and all 23 occupants were killed.
It appears the manifest was not reflecting the truth as it was mentioned a total weight of 30 tons, an incorrect value. The crew was performing a flight from Chkalovsky to Petropavlovsk-Kamchatsky with an intermediate stop in Abakan to refuel. Because the total weight was substantially above the MTOW, the climb gradient was insufficient, resulting in a collision with a mountain that the crew was unable to locate due to the low visibility caused by night.
