NTSB narrative
The student pilot was completing the last of his touch-and-go landings at a local airport. During the flare he said the airplane began to drift to the right and said he noticed the left wing getting ready to contact the ground, as if in a ground loop condition. The pilot applied full throttle in an attempt to fly away. He stated the airplane did not want to fly so he elected to close the throttle and attempted to straighten out the airplane for landing. The aircraft contacted the ground and subsequently nosed over. The gascolator was compromised during the crash, which allowed unregulated fuel to enter the engine cowling. The postcrash fire ensued which destroyed the airplane. The pilot reported that the weather conditions at the time of the crash as reported on ATIS were winds 070 at 4 knots.
Probable cause
The pilot-in-command's failure to maintain directional control. A factor in this accident was the inadvertent ground loop swerve.

- 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.
