On Sunday, February 14, 1993, at approximately 1545 central standard time, a H. Raymond constructed Busby Mustang II home built airplane, was destroyed when it collided with vehicles and trees during an attempted aborted landing near Arlington, Texas. The airplane, owned and operated by the commercial pilot, was on a 14 CFR Part 91 local personal flight. No flight plan was filed and visual meteorological conditions prevailed in the area. The pilot, the sole occupant, was not injured. The pilot stated that after a normal landing profile, the airplane touched down and he applied normal braking. He further stated that the normal braking had "no appreciable effect" and that braking action was poor on the 1,700 foot wet sod runway. He realized that he would run off the end of the runway and aborted the landing. He stated that he applied full throttle, but felt that the engine did not develop full takeoff power. The airplane subsequently became airborne again and collided with the left wing of a Cessna 150 parked on the left side and end of the runway, then collided with a car that was parked off the end of the runway. Upon impact with the car, the airplane yawed left and collided with trees and the ground. Witnesses stated that the airplane appeared to be "hot" and landed long and that the abort was initiated with flaps fully extended. One witness stated that the airplane appeared to have landed about 3/4 of the way down the runway. The witnesses also stated that the engine sounded normal throughout the approach and abort.
