An engine failure was simulated during the takeoff (at V1). The yaw was corrected, and the Convair lifted off the runway. When airborne, the left wing dropped slowly, causing the aircraft to drift to the left. Power was restored to the no. 1 engine, but the left wing hit the ground and the aircraft crash-landed. The nose and right main gear collapsed.

Probable Cause:

POSSIBLE FACTORS: "a) Wind shear effect; b) Roughness on wing surfaces (ice) could have affected climb; c) The aircraft slipped to the left when power restored on left engine. The slipstream then temporarily will give yaw to the left and increase the slip; d) Banking attitude towards the 'failed' engine side caused the Vmc to increase over calculated V2."
