## Probable cause

THE PREMATURE ROTATIION AND LIFTOFF BY THE PILOT, WHICH RESULTED IN AN INADVERTENT STALL.   A FACTOR RELATED TO THE ACCIDENT WAS:  THE TAILWIND.

## 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
  - weather condition - tailwind (contributing factor)
  - rotation - premature, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, takeoff

## Analysis

THE PILOT BEGAN TO TAKEOFF WITH A TAILWIND. JUST AFTER LIFT-OFF, THE AIRCRAFT ROLLED LEFT AND IMPACTED THE GROUND BESIDE THE RUNWAY.  NO PREIMPACT MECHANICAL FAILURE OR MALFUNCTION OF THE AIRCRAFT OR ENGINE WAS FOUND DURING THE INVESTIGATION.
