NTSB narrative
The airplane sustained substantial damage on impact with terrain when the airplane exited the runway during an aborted landing. The instructor reported, "The aircraft turned final and flew a slightly low and fast approach to the runway. The aircraft touched down flat on the runway and because of the excess speed the aircraft bounced into the air a considerable amount. At this point the landing was aborted. As the power was advanced the aircraft began a left turn and drifted off the runway. At this point the instructor called for complete control of the aircraft and returned to wings level pitch attitude; however, despite the application of full power the aircraft refused to climb and touched down right main first on the grass to the north side of the runway. The aircraft then swung nose right shearing off the nose gear and left main gear causing the propeller to strike the ground." The pilot reported no mechanical malfunctions associated with the airplane in reference to the flight. An examination of the wreckage revealed that the flight controls were operational and correct and that the engine controls were operational.
Probable cause
The dual student pilot not maintaining airplane control during the go-around and the flight instructor pilot's inadequate remedial action resulting in the airplane's uncontrolled descent.

- 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, coordinates. 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.
