The defining event best describes what happened. - [Approach-VFR go-around: Loss of control in flight](https://openairdocs.org/ntsb-events/240) (defining event); cases with it: [Cessna 172S, 49 cases](https://openairdocs.org/ntsb-events/240/sequence.md?model=2072439), [All aircraft, 5,002 cases](https://openairdocs.org/ntsb-events/240/sequence.md) ## Analysis The instructor and student pilot reported the student pilot was practicing landings. During the first landing, after crossing the runway numbers, the airplane touched down and "ballooned" back up into the air. The airplane "bounced" on the runway a second time and the instructor pilot told the student to apply full power and perform a go around. The student applied full power and pulled back hard on the control yoke. The nose of the airplane pitched up, the airplane drifted to the left and stalled, subsequently impacting terrain off the left side of the runway. No mechanical malfunction/failure with the airplane that would have precluded normal airplane operation was reported. ## Factual narrative The instructor and student pilot reported the student pilot was practicing landings.

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.
