## Probable cause

THE PILOT'S FAILURE TO MAINTAIN AIRCRAFT CONTROL.  A FACTOR IN THE ACCIDENT WAS THE PILOT'S LACK OF EXPERIENCE IN AIRCRAFT TYPE.

## 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
  - terrain condition - loose gravel/sandy
  - aircraft control - not maintained, pilot in command (cause)
  - lack of total experience in type of aircraft, pilot in command (contributing factor)

## Analysis

A TAILWHEEL AIRPLANE GROUNDLOOPED DURING TAKEOFF FROM A GRAVEL ROAD.  THE PRIVATE PILOT STATED A MAIN GEAR HIT A BUMP NEAR LIFTOFF SPEED, AND HE LOST CONTROL.  THE PILOT CHECKED OUT IN TYPE A YEAR EARLIER ON A ONE HOUR FLIGHT AND HAD ABOUT TWO HOURS IN TYPE SINCE THEN.
