## Probable cause

THE FAILURE OF THE PILOT TO ENSURE THE HELICOPTER HAD NO LATERAL MOTION UPON TOUCHDOWN.

## Sequence of events

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

- Loss of control - on ground/water, landing - flare/touchdown
  - rotorcraft flight controls - improper use of, pilot in command(cfi) (cause)
  - cyclic - improper use of, pilot in command(cfi) (cause)

## Analysis

THE HELICOPTER WAS APPROACHING TO LAND AT AN AIRPORT WITH RESTRICTIVE NOISE ABATEMENT PROCEDURES.  THE PILOT ARRIVED OVER THE AIRPORT, APPROXIMATELY 1000 FEET AGL AND WAS CLEARED TO A TAXIWAY.  THE PILOT DESCRIBED THE DESCENT AS STEEP AND HE MISSED HIS DESIRED LANDING AREA. THE PILOT ELECTED TO LAND IN A GRASSY AREA NEAR THE DESIGNATED LANDING AREA, HOWEVER, HE TOUCHED DOWN WITH A LEFT LATERAL MOVEMENT AND UPON TOUCHDOWN, THE HELICOPTER ROLLED OVER.
