NTSB narrative
The flight instructor stated that the accident flight was flight lesson 1 with the student and her first flight as a flight instructor. The winds were forecast to be variable at 4 knots and the flight taxied to the active runway to complete preflight tasks. After a normal engine run up, the flight was instructed to line-up and wait for a Cessna Caravan that had just departed. After being cleared for takeoff, the flight instructor initiated the takeoff roll and at 60 knots, rotated. When the flight was about 20 to 30 ft above the runway, they experienced a very strong rolling force to the left, which she attempted to correct with a considerable amount of right aileron and right rudder. She then reduced power to abort the takeoff, but the airplane impacted the runway hard and bounced twice, which resulted in substantial damage to the fuselage. She taxied off the runway and the airplane was towed to the maintenance hangar.
A pilot who had flown the airplane earlier that day reported the airplane flew “ok” with no discrepancies reported. The flight instructor reported and a post-accident examination corroborated that, there were no pre-accident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The failure of the flight instructor to maintain the proper rate of descent during the aborted takeoff.

- 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, cause areas. 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.
