NTSB narrative
The pilot receiving instruction was flying the airplane from the right seat. He made four touch-and-go landings. The fifth approach was normal, with a flap setting of 30 degrees, but the flare was too high and the airplane landed hard and bounced. The pilot added full power and began to fly down the runway for a go-around. The instructor "adjusted the flap position and the airplane lost all lift and fell to the runway." The airplane slid across a grassy area and came to a halt on the taxiway.
Probable cause
the instructor's inadequate supervision of the flight and his premature raising of the flaps, resulting in a hard landing.

- 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.
