NTSB narrative
THE RATED STUDENT PILOT WAS RECEIVING A MOUNTAIN FLYING CHECKOUT FROM THE PIC/FLIGHT INSTRUCTOR. TAKEOFF WAS MADE FROM A 7200 FT. RUNWAY INTO A 15 KNOT HEADWIND. TEN DEGREES OF FLAPS WERE USED AND THE DENSITY ALTITUDE WAS 10,089 FEET MSL. THE AIRPLANE CLIMBED TO APPROXIMATELY 15 FEET AGL, THEN THE AIRSPEED BEGAN TO DECAY AND THE STALL WARNING HORN SOUNDED. THE FLIGHT INSTRUCTOR APPLIED FORWARD CONTROL YOKE PRESSURE AND CALLED FOR GEAR RETRACTION. THE PILOT RECEIVING INSTRUCTION DID NOT FEEL THIS WAS PRUDENT. INSTEAD, HE RETRACTED THE FLAPS AND ABORTED THE TAKEOFF. THE AIRPLANE TOUCHED DOWN IN A FIELD LEFT OF CENTERLINE, WENT THROUGH A BARBED WIRE FENCE, AND COLLIDED WITH A DITCH.
Probable cause
THE DUAL STUDENT'S POOR TAKEOFF TECHNIQUE, HIS FAILURE TO MAINTAIN DIRECTIONAL CONTROL, AND INADEQUATE SUPERVISION BY THE PIC CFI. A FACTOR WAS: THE DUAL STUDENT'S LACK OF EXPERIENCE IN MOUNTAIN FLYING.

Source notes (4)
- 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.
- API snapshot SHA-256: 4f055009ad62171cc17bc58e35669ac6e17c4aca6e1ae4e6dc3dde6ca961d680; retrieved 2026-09-23T04:25:46.187Z.
