The defining event best describes what happened. - [Landing-landing roll: Collision during takeoff/land](https://openairdocs.org/ntsb-events/490) (defining event); cases with it: [Cessna 172R, 3 cases](https://openairdocs.org/ntsb-events/490/sequence.md?model=2072401), [All aircraft, 1,309 cases](https://openairdocs.org/ntsb-events/490/sequence.md) ## Analysis The solo student pilot was performing a touch-and-go landing and touched down too far down the runway. The student pilot trimmed the airplane, raised the flaps and advanced the throttle for takeoff. He became unsure of the runway distance remaining so he reduced the throttle to idle and applied the brakes to abort the takeoff. The brakes locked up several times while he kept the airplane on the runway centerline. Realizing the airplane was not slowing enough, the student pilot lowered the airplane's flaps to 30 degrees and pushed forward on the control yoke to add drag and decrease lift. The airplane slowed, but not enough to stop it from going off the end of the runway and impacting trees. The student pilot reported that there were no mechanical malfunctions or failures with the airplane prior to the accident. ## Factual narrative The solo student pilot was performing a touch-and-go landing and touched down too far down the runway.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
