## Probable cause

THE PILOT'S INADVERTENT LIFT OFF AND FAILURE TO MAINTAIN AIRCRAFT CONTROL WHICH RESULTED IN AN INADVERTENT STALL. THE PILOT'S LACK OF RECENT EXPERIENCE AND LACK OF EXPERIENCE IN TYPE OF AIRPLANE WERE FACTORS IN THE ACCIDENT.

## Sequence of events

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

- Loss of control - in flight, takeoff - initial climb
  - lack of total experience in type of aircraft, pilot in command (contributing factor)
  - lack of recent experience, pilot in command (contributing factor)
  - lift-off - inadvertent, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
