Primary finding
Probable cause
The student pilot’s failure to maintain directional control during takeoff.
Investigator assessment
Analysis narrative
On his third solo flight, the student pilot was practicing takeoffs and landings on the 3,703-foot-long by 100-foot-wide runway, and he had successfully completed one circuit. His flight instructor, who witnessed the accident, stated that on the second takeoff attempt the aircraft swerved to the left of the runway centerline as both main tires skidded, and the airplane impacted a runway sign. The student pilot continued the takeoff and the airplane became airborne. While the airplane was in the traffic pattern, the engine seized due to damage sustained during the takeoff sequence. The flight instructor provided guidance to maintain airspeed and aircraft control over the radio, and the student pilot subsequently landed without further incident. In his statement, the student pilot explained that the left brake was sticking during his initial takeoff roll; however, examination of the airplane after the accident revealed no mechanical anomalies. The flight instructor reported that the student pilot had been instructed to “abort the takeoff by pulling the throttle to idle and applying the brakes as appropriate” if the takeoff roll was not normal.
