Description
During takeoff from Lensk Airport, Russia, the rear door opened. Two passengers in the rear left their seats to close the door. This caused the centre of gravity to move past the rear limit. As a result the nose pitched up, causing the plane to stall at a supercritical angle of attack. The An-2 struck the runway at descent rate of 6-8 m/s.
