The pilot receiving instruction’s failure to maintain directional control during the takeoff roll, resulting in a runway excursion and ground collision.
Investigator assessment
Analysis narrative
Both pilots reported that during the takeoff roll, the pilot receiving instruction lost directional control of the airplane and it veered off the runway. The airplane subsequently collided with a parked unoccupied airplane. The left horizontal stabilizer and elevator sustained substantial damaged. The flight instructor reported that the airplane was not equipped with brakes at the right seat position. Both pilots reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
