Beschrijving:
The aircraft crashed into a soybean field shortly after takeoff from runway 22.

Probable Cause:

PROBABLE CAUSE: "The flight crew's inadequate and uncoordinated response to the No 2 engine fire warning. The flight engineer failed to correct a gradual power decay on the other engines which occurred while he was retarding the No 2 engine throttle, and the power decay went uncorrected by the pilot and co-pilot. The lack of co-ordination and the lack of corrective action may have been caused by the lack of recent flight crew experience in the L-1049 aircraft.
Contributing to the accident was the aircraft's over maximum take-off weight, the crew's use of less than full power for take-off, and the use of less than take-off cowl flaps which precluded adequate engine cooling."
