Investigator assessment
Analysis narrative
The student pilot was performing his seventh solo takeoff, when the tower controller cleared him for takeoff and told him to expedite due to other traffic. He added full throttle and looked down to check his airspeed; however, when he looked back up to the runway the airplane was left of the runway centerline. The student pilot applied right rudder and the airplane veered to the right. He then removed the right rudder input and the airplane “darted” to the left, exited the runway, and impacted a ditch and a runway sign. The airplane came to rest in the grass alongside of the runway. The airplane sustained substantial damage to the left and right wings. The student pilot reported no preaccident mechanical failures or malfunctions that would have precluded normal operation.
