Accident Details
The accident occurred during takeoff from a 5000-foot-long asphalt runway. Conditions were calm wind with a density altitude of 8800 feet. The pilot attempted three takeoffs; the first two were aborted when the aircraft did not reach takeoff speed.
Pilot's Account
According to the pilot, prior to the first takeoff attempt, detonation occurred during the runup. She enriched the mixture and then applied full power with the mixture control out about 2 inches. The aircraft did not accelerate properly, so she aborted the takeoff. During the second attempt, the pilot stated she did not advance the throttle all the way. On the third attempt, the pilot reported that speed improved to 65 knots indicated airspeed. As the end of the runway approached, she pulled the aircraft off the ground. A stall warning horn sounded, the nose dropped, and with no additional power, the aircraft hit the ground and rolled through the grass.
Performance Data
According to the takeoff chart for this aircraft, the takeoff distance under the prevailing conditions should have been approximately 2000 feet. The actual outcome differed significantly from the charted performance.
