Incident
On the takeoff roll at Arkhangelsk-Talagi Airport, the aircraft reached a speed of 160 km/h when the captain initiated rotation. The aircraft, however, did not respond and failed to become airborne. Instead of aborting the takeoff, the captain asked the copilot to investigate the issue. The aircraft continued along the runway for 2,250 meters before overrunning the end.
Sequence of Events
After leaving the runway, the aircraft traveled through bushes for 314 meters. It then struck a localizer antenna and a small building located 116 meters further. The aircraft, now out of control, continued for another 55 meters before colliding with a concrete pillar. It came to rest engulfed in flames.
Aftermath
The copilot was killed in the accident. The captain, flight engineer, and 11 passengers sustained injuries, while the remaining 17 occupants were unharmed. The aircraft was destroyed by the impact forces and the subsequent fire.
Probable Cause
The official investigation determined that an electrical problem from an unknown source occurred on the elevators locking system, causing the elevators to be jammed during the takeoff procedure. The reaction of the captain was inadequate as he failed to abandon the takeoff manoeuvre when the problem was detected.
