NTSB narrative
THE STUDENT (A RATED PILOT) & THE INSTRUCTOR (CFI) TOOK OFF AT 1645 EST ON A FLIGHT TO PROVIDE EXPERIENCE IN COMPLEX AIRCRAFT TO THE STUDENT. THE LESSON WAS TO INCLUDE MINIMUM CONTROL AIRSPEEDS/STALLS, STEEP TURNS, AND EMERGENCY PROCEDURES. SUBSEQUENTLY, THE AIRCRAFT WAS FOUND WHERE IT HAD CRASHED ON A WOODED HILLTOP. THERE WERE NO KNOWN WITNESSES TO THE ACCIDENT. AN EXAM OF THE WRECKAGE REVEALED THE AIRCRAFT HAD CRASHED IN A STEEP DESCENT. THE ONLY DAMAGE TO TREES WAS DIRECTLY ABOVE THE WRECKAGE. CUT TREE LIMBS WERE FND IN THAT AREA. THE LEADING EDGES OF BOTH WINGS WERE COMPRESSED REARWARD, THE INSTRUMENT PANEL WAS DISPLACED FORWARD, THE BACK OF THE RIGHT FRONT SEAT WAS DISPLACED REARWARD, AND THE LEFT FRONT SEAT WAS DISPLACED TO THE RIGHT & SLIGHTLY REARWARD. NO PREIMPACT PART FAILURE OR MALFUNCTION WAS FOUND. OFFICIAL TWILIGHT WAS AT 1711 EST.
Probable cause
THE FAILURE OF THE FLIGHT INSTRUCTOR (CFI) TO ATTAIN REMEDIAL ACTION AFTER CONTROL OF THE AIRPLANE WAS LOST FOR AN UNKNOWN REASON.

- 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.
