## 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.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Undetermined, takeoff - initial climb
  - aircraft control - improper, dual student (cause)
  - directional control - not maintained, dual student (cause)
  - lack of total experience in type operation, dual student (contributing factor)
  - remedial action - attempted, pilot in command(cfi)
  - supervision - inadequate, pilot in command(cfi) (cause)
  - aborted takeoff - performed, dual student
  - terrain condition - ditch
- Overrun, takeoff - aborted
- On ground/water collision with object, takeoff - aborted

## Analysis

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.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
