## 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
  - landing gear,skid assembly - movement restricted (contributing factor)
  - aircraft performance,rolling maneuvers - extraneous (cause)
  - lift-off - improper, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
- Roll over, takeoff - roll/run

## Analysis

ACFT HAD BEEN PARKED IN AN OPEN FIELD AND WHEN THE PLT RETURNED HE NOTICED THAT THE LEFT SKID HAD SUNK INTO THE MUD. AFTER ENG START AND RUN UP, THE PLT ATTEMPTED TO TAKEOFF WITH RIGHT CYCLIC APPLIED TO UN-STICK THE LEFT SKID. THE ACFT LIFTED OFF WITH A RIGHT ROLL VECTOR AND ENTERED DYNAMIC ROLL OVER. THE ROLL CONTINUED UNTIL THE MAIN ROTOR BLADES CONTACTED THE GROUND. THE ACFT CAME TO REST ON ITS RIGHT SIDE. THE PLT FLT TIME WAS NOT REPORTED.
