NTSB narrative
The purpose of the flight was to conduct a biennial flight review. The private pilot and check pilot had spent an hour in the traffic pattern reviewing takeoffs, landings, and emergency procedures. The check pilot reported that the private pilot had conducted the maneuvers satisfactorily, and he requested that the private pilot take him to the accident location to simulate engine out procedures. Once at the accident location, the check pilot reduced the power to idle and instructed the pilot to conduct the approach on a dirt road. The check pilot reported that at 50 feet agl, he was satisfied with the maneuver and instructed the pilot to go around. The private pilot stated that he applied full power to go around, but the airspeed and the aircraft were too low and the application of power could not arrest the rate of descent prior to contacting the ground. The check pilot said that the pilot did not react to his request to discontinue the maneuver and froze on the controls. The check pilot was unable to gain control of the aircraft prior to it touching down off the dirt road and striking a dirt mound in the grass. No mechanical anomalies were noted with the aircraft or engine by either of the pilots.
Probable cause
The check pilot's inadequate supervision of the flight and his failure to ensure that an adequate altitude margin existed during the maneuver.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1999-04-15.
