## Probable cause

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL. A FACTOR WAS HIS ATTEMPT TO TAKEOFF WITHOUT USING ALL AVAILABLE RUNWAY.

## Sequence of events

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

- Loss of control - on ground/water, takeoff - roll/run
  - all available runway - not used, pilot in command (contributing factor)
  - directional control - not maintained, pilot in command (cause)

## Analysis

DURING A DAYLIGHT DEPARTURE FROM A PRIVATE AIRSTRIP, THE PILOT LOST CONTROL AND RAN OFF THE RUNWAY RESULTING IN THE AIRPLANE BEING DESTROYED BY IMPACT FORCES AND POST CRASH FIRE. THE PILOT HAD LANDED AT THE PRIVATE AIRSTRIP OWNED BY A LOCAL RESTAURANT WITH THE INTENT OF EATING A MEAL. A WORKER SIGNALLED BY WAVING HIS ARMS THAT THE RESTAURANT WAS CLOSED SO THE PILOT ATTEMPTED A SHORT FIELD TAKEOFF AS HAD BEEN DEMONSTRATED TO HIM BY HIS INSTRUCTOR. FULL POWER WAS APPLIED AND WHEN BRAKES WERE RELEASED THE AIRPLANE SWERVED TO THE LEFT INTO AN EMBANKMENT.
