The Fokker aircraft became airborne after a ground run on runway 35 of approx. 3200 feet. At a height of 8-10 m the aircraft suddenly yawed left and pitched nose-down. The aircraft contacted the ground again and struck a drainage ditch, skidded, disintegrated and caught fire.
With the conditions at the time of takeoff, the aircraft should have reached rotation speed after a ground roll of 850 m(2800 feet). From the flight data recorder it was determined that the aircraft became airborne at 124 knots after a 975 m (3200-foot) roll . The speed increased to 133 knots and then dropped to 124 knots, and the aircraft veered left.
PROBABLE CAUSE: “The aircraft stalled on takeoff due to over rotation and frost accretion on the wings.”
