The NTSB's narrative final · quoted from the NTSB record
While the student pilot was conducting touch-and-go landings, about the time of power application after landing, the airplane veered left and departed the runway onto the adjacent grass. The airplane subsequently struck a sign, impacted a gopher hole, and came to rest near a berm, sustaining substantial damage to the airframe and horizontal stabilizer. Three distinct tire tracks were visible in the grass up to the gopher hole. A postaccident examination of the left main landing gear assembly revealed overstress fractures from a single loading event, which was likely the impact with the gopher hole; no preimpact mechanical malfunctions or failures that would have precluded normal operation were found. FAA guidance indicates that an abrupt application of power may result in the airplane yawing sharply to the left. It is likely that at the application of takeoff power, the student pilot failed to apply an appropriate amount of rudder correction and the airplane departed the runway. The flight instructor did not recognize the student’s failure to maintain directional control in a timely manner and failed to take appropriate remedial.
