Aircraft involved
Probable cause & findings
The pilot’s failure to maintain directional control during takeoff.
Factual narrative
The student pilot reported that he was practicing touch-and-go takeoffs and landings. The landing was uneventful; however, as the airplane accelerated for takeoff, it veered to the left. Despite his control inputs, the airplane continued to veer to the left and struck a runway sign, substantially damaging the fuselage and empennage. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
