NTSB narrative
THE STUDENT & INSTRUCTOR (CFI) WERE PREFLIGHTING THE ACFT TO FLY ON A COLD MORNING. TO FACILITATE BETTER ENG STARTING, THE CFI ELECTED TO TURN THE PROP WHILE THE STUDENT 'PUSHED THE PRIMER IN.' HE TOLD THE STUDENT TO CHECK THAT THE MAG & MASTER SWS WERE OFF & THE STUDENT ACKNOWLEDGED. ON THE 2ND 'TURN THROUGH,' THE ENG STARTED & RAN APRX 5 SEC. THE CFI WAS INITIALLY CLR OF THE PROP, BUT AS HE WAS BACKING AWAY, HE SLIPPED ON INCE & HIS RGT LEG WENT IN THE PATH OF THE TURNING PROP. HE WAS HOSPITALIZED WITH A SEVERE LACERATION & THE PROP WAS SLIGHTLY BENT. AN INV REVEALED THE STUDENT WAS AT THE CONTROLS WITH THE KEYS REMOVED FROM THE MAG SW. A FURTHER EXAM REVEALED THE MAG CIRCUITRY WAS NORMAL, EXCEPT THE MAGNETO KEY COULD BE REMOVED WHILE THE MAG SW WAS IN THE 'LEFT' POSITION.

- 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.
