Unfallbericht:
The Antonov had made a refueling stop at Mukalla and was bound for Sharjah, carrying 7 tons of fish.
During takeoff from Mukalla's runway 06, at the speed 225 km/h, the nose landing gear retracted. The captain decided to abort the takeoff. He steered the plane to the left to avoid a collision with a radio-technical equipment car.
The aircraft failed to stop on the runway and ran onto rugged sand terrain, 2 m below the runway level. The aircraft hit a hill and tilted to the right as it came to rest 400m from the runway end and 30m left from extended runway center line.

Probable Cause:

Conclusions:
The reason of this occurrence is early retraction of landing gears without order of the Captain before aircraft airborne.
Actions of flight engineer in violation of technology of standard operating procedures, by fixing of landing gear switch to "retract position" after that to "neutral" without report to the Captain leaded to rise and development of occurrence.
