According to his written statement, the pilot stated that his airspeed did not increase above 40 knots and he elected to abort the takeoff. The pilot stated that he pulled back on the yoke to decelerate and applied the brakes. He stated that the airplane bounced off of the ground two or three times. During the impact with the runway the landing gear collapsed and the propeller struck the runway resulting in substantial damage. Witnesses interviewed by a Federal Aviation Administration (FAA)inspector said that the airplane was approximately 30 to 40 feet above the ground before it descended back to the runway and bounced three times. The FAA inspector calculated the density altitude to be 7,700 feet and the weight of the airplane to be near its maximum takeoff weight. The FAA inspector confirmed that there were no mechanical anomalies or failures with the airplane, engine, or related systems prior to the accident.
