NTSB narrative
During the instructional flight, the student pilot initiated the takeoff roll normally. As the airplane accelerated, it began to weave back and forth until it suddenly yawed sharply to the left. The flight instructor applied back pressure to the control yoke and the airplane became airborne. As the student pilot relinquished control of the airplane, she removed her hand from the throttle and inadvertently reduced it to the idle position. The flight instructor immediately advanced the throttle to the full open position as the airplane started to descend. Subsequently, the right main landing gear struck the runway precision approach path indicator lights and impacted the ground, resulting in structural damage to the fuselage. The flight instructor and student pilot stated that there were no anomalies with the flight control system or the engine at the time of the accident.
Probable cause
The student pilot's failure to maintain directional control during takeoff and the flight instructor's inadequate supervision of the flight and delay in remedial action.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
