NTSB narrative
THE ACFT SWERVED OFF THE RWY, COLLIDED WITH A DITCH AND NOSED OVER. THE PILOT WAS A STUDENT ON HIS 1ST SOLO AFTER OVER 42 HOURS OF DUAL INSTRUCTION. HE FLEW OVER 28 HOURS OF DUAL INSTRUCTION AND MADE ABOUT 60 LANDINGS DURING THE LAST 90 DAYS. ON THE DAY OF THE ACCIDENT THE STUDENT WAS USING RWY 16. THE WIND WAS FROM 140 DEGREES AT 4 TO 6 KTS. THIS EQUATES TO A CROSSWIND COMPONENT FROM THE LEFT OF 2 KTS. THE CFI OBSERVED THE STUDENTS FIRST SOLO LANDING. HE SAID THE ACFT DRIFTED OFF TO THE LEFT DURING THE FLARE. THE ACFT BOUNCED ON THE GRASS BESIDE THE RWY, WENT INTO A DITCH AND BOUNCED BACK INTO THE AIR WHEN IT HIT THE OPPOSITE EMBANKMENT. THEN THE ACFT LANDED ON ITS NOSE AND NOSED OVER. THE PILOT SAID HE TRIED TO CORRECT BACK TO THE RWY DURING FLARE BUT THE ACFT 'STARTED TO GO SIDEWAYS'. WHEN HE SAW THE GRASSTHE STUDENT ADDED POWER TO GO-AROUND BUT THE STALL WARNING SOUNDED AND HE PULLED THE POWER OFF BEFORE HITTING THE DITCH.

- 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.
