Circumstances:
The aircraft was completing a cargo flight from Moscow-Zhukovsky Airport to Petropavlovsk-Kamchatsky with an intermediate stop in Abakan, carrying 13 passengers, 10 crew members and a load of 30 tons of various goods. Following a night takeoff, the aircraft climbed to a height of 200 metres then encountered difficulties to climb anymore. According to published procedures, the pilot-in-command was supposed to initiate a turn after a course of 4 km but he continued a straight-in route until the aircraft struck the slope of a snow covered mountain located 13,4 km from the runway end. The aircraft disintegrated on impact and all 23 occupants were killed.
Probable cause:
It appears that the manifest was not reflecting the truth as it was mentioned a total weight of 30 tons, an incorrect value. 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. It was also reported that the crew failed to follow the published departure procedures.
