NTSB narrative
The airplane rolled into a ditch during a forced landing following a partial loss of engine power. The flight instructor reported that the engine power loss occurred while climbing between 400 and 500 feet above ground level. Thereafter, the instructor reversed course, but the airplane had insufficient altitude to return to the airport, so the instructor landed on desert terrain. Upon slowing between 20 and 30 miles per hour, the airplane impacted the upslope side of a ditch. Thirty-five gallons of fuel were in the airplane's tanks when the 25-minute-long flight was initiated. The reason that the engine lost partial power was not ascertained.
Probable cause
The partial loss of engine power for undetermined reasons.

- 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.
