Collided with the terrain following a loss of control during a takeoff ground roll on runway 34 in gusty crosswind conditions. It struck a ditch and became airborne shortly until the left wing fuel tank exploded.

Probable Cause:

PROBABLE CAUSE: "Failure of the pilot-in-command (PIC) to maintain directional control of the airplane during the takeoff roll in a gusty crosswind, his failure to abort the takeoff, and failure of the copilot to adequately monitor and/or take sufficient remedial action to help avoid the occurrence. Factors relating to the accident included the gusty crosswind condition, the drainage ditch, the flight crew's inadequate preflight, the Nose Wheel Steering Control Select Switch in the "Handwheel Only" position, and the lack of standardization of the two companies' operations manuals and Interchage Agreement.
