## Probable cause

INADEQUATE PREFLIGHT BY THE PILOT BY NOT IDENTIFYING AND REMOVING THE TIE-DOWN.

## Sequence of events

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

- Roll over, takeoff
  - aircraft preflight - inadequate, pilot in command (cause)
  - tie down - not identified, pilot in command (contributing factor)

## Analysis

THE PILOT WAS ATTEMPTING A LIFTOFF FROM A TRAILER TO FLIGHT TAXI THE HELICOPTER TO THE FLIGHT LINE.  HE SAID THAT AS HE TRIED TO COME TO A HOVER, THE HELICOPTER WENT INTO A DYNAMIC ROLLOVER AND WAS THROWN TO THE GROUND.  ONE OF THE SKIDS WAS STILL ATTACHED TO THE TRAILER.
