Accident Sequence
During the second aborted takeoff attempt, the aircraft crashed. The pilot reported that the aircraft was not accelerating properly on the first takeoff attempt. On the second attempt, the pilot stated that the engine lost power.
Witness Observations
Ground witnesses observed that the air conditioner condenser door was open and that the flaps were up during both takeoff attempts. The pilot reported that he had turned off the air conditioner and deployed 10 degrees of flaps.
Examination Findings
Examination of the wreckage revealed that the air conditioner condenser door was open, the compressor clutch was disengaged from the engine, and that the flaps were up.
Performance Calculations
Calculations indicated that the aircraft was 300 pounds over the maximum gross takeoff weight. Calculations also indicated that the aircraft would require 2,600 feet of ground roll to take off, and a total of 4,700 feet to clear a 50-foot obstacle. The runway has a published length of 4,020 feet with an additional 200 feet of overrun. There were trees at the departure end of the runway.
