## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

AFTER A THOROUGH PREFLIGHT, ^PRIVACY DATA OMITTED^ AND HIS PASSENGER ^PRIVACY DATA OMITTED^ DEPARTED MARTIN STATE AIRPORT (KMTN).  ^PRIVACY DATA OMITTED^ IS NOT A CERTIFIED PILOT.

^PRIVACY DATA OMITTED^ STATED THAT HE ALLOWED HIS PASSENGER TO "RIDE ALONG" ON THE CONTROLS SO HE COULD APPRECIATE THE EXPERIENCE OF FLYING A HELICOPTER.

PRIOR TO LANDING THE PILOT SAID THE HELICOPTER BEGAN AN UNCOMMANDED CLOCKWISE TURN - ROTATING OVER 720 DEGREES BEFORE MAKING A FIRM LANDING. THE HELICOPTER THEN ROLLED ONTO ITS PORT SIDE.

POST-ACCIDENT INSPECTION REVEALED NO MECHANICAL ABNORMALITIES OTHER THAN THOSE ATTRIBUTED TO THE ACCIDENT.
