Sovetskiy

Some passengers were late and the crew apparently hurried the departure to avoid a night flight to Svetly. Doing so, the crew failed to prepare the flight properly and did not proceed to any engine runup prior to taxi and takeoff. During the taxi manoeuvre, the aircraft suffered controllability problems so the crew selected the propeller lever to the fine pitch position. The takeoff procedure was initiated without checks and the crew forgot that the propeller lever was not in the takeoff position. After liftoff, at a height of 3-5 metres, the aircraft encountered difficulties to gain height and speed. The crew attempted an emergency landing when the aircraft collided with trees and crashed in a wooded area. All 15 occupants escaped uninjured while the aircraft was damaged beyond repair.

Following an uneventful flight from Perm, the crew started the descent to Sovetskiy Airport and was informed about the weather conditions at destination with ceiling down to 80 meters and an horizontal visibility estimated to 2 kilometers, which was below minimums. Despite this situation, the crew decided to continue the approach and deliberately passed below the minimum descent altitude probably to establish a visual contact with the ground. On short final, the aircraft struck tree tops (25 meters high), banked right and crashed in a wooded area located 700 meters short of runway 30, about 250 meters to the right of its extended centerline, bursting into flames. Eight passengers were rescued while 32 other occupants were killed.

After a takeoff distance of 430 meters completed in 26 seconds, the pilot-in-command initiated the rotation at a speed of 120 km/h. The airplane continued to climb when, at a height of 10 meters, the left engine failed. The airplane continued to climb until a height of 50 meters when it banked left to an angle of 80° then stalled and crashed at a speed of 170 km/h not far from the runway end. While all six passengers were injured, all three crew members were killed.
