## Probable cause

THE INADEQUATE PREFLIGHT PLANNING AND PREPARATION BY THE PILOT, AND HIS FAILURE TO REMOVE A TIE DOWN ROPE BEFORE TAKEOFF.

## Sequence of events

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

- Loss of control - in flight, takeoff
  - preflight planning/preparation - inadequate, pilot in command (cause)
  - tie down - improper, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled
- Roll over, other

## Analysis

THE PILOT TOOK OFF TO A HOVER FROM THE PARKING RAMP, LOST CONTROL, AND THE ACFT IMPACTED THE GROUND AND ROLLED OVER. A BROKEN ACFT TIEDOWN ROPE WAS FOUND BESIDE THE WRECKAGE.
