## Probable cause

THE FLIGHT INSTRUCTOR'S PREMATURE LIFTOFF. RELATED FACTORS ARE THE INSTRUCTOR'S LACK OF TOTAL EXPERIENCE IN THE ACCIDENT MAKE AND MODEL AIRPLANE, AND THE UNSUITABLE TERRAIN ENCOUNTERED DURING THE ROLL-OUT.

## Sequence of events

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

- Overrun, takeoff - aborted
  - terrain condition - grass
  - lift-off - premature, pilot in command
  - lack of total experience in type of aircraft, pilot in command (contributing factor)
  - terrain condition - dirt bank/rising embankment (contributing factor)
  - unsuitable terrain or takeoff/landing/taxi area - encountered, pilot in command (contributing factor)

## Analysis

THE PILOT REPORTED THE AIRPLANE '...DID NOT ACHIEVE FLYING SPEED...' BEFORE LIFT-OFF.  THERE WAS NO CLAIM OR EVIDENCE OF PRE-IMPACT MECHANICAL MALFUNCTION.  THE PILOT STATED HE HAD 270 HOURS TOTAL FLIGHT EXPERIENCE, INCLUDING 2.4 HOURS IN THE ACCIDENT MAKE AND MODEL AIRPLANE.  THE PILOT WAS TAKING OFF FROM A GRASS RUNWAY (2,540' X 260'), WITH TWO PASSENGERS, AND 32 GALLONS OF FUEL ON BOARD THE AIRCRAFT.  THE PILOT ESTIMATED THE TEMPERATURE TO BE 88 DEGREES FAHRENHEIT.
