## Narrative

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

PILOT AND PASSENGER WERE TRAVELING FROM OIL PLATFORM SS266B TO PLATFORM ST317-A.  WHILE ON A STRAIGHT IN APPROACH TO THE PLATFORM, THE AIRCRAFT BEGAN TO SPIN TO THE RIGHT.  AN EYEWITNESS SAID THE AIRCRAFT SPUN CLOCKWISE 8-10 TIMES WITH DEBRIS FALLING OUT AS IT SPUN AND HEARD A "SNAP" SOUND AS IF SOMETHING BROKE.  THE AIRCRAFT THEN "WENT SILENT AND FELL STRAIGHT DOWN" IMPACTING THE WATER AND SINKING.  THE AIRCRAFT WAS DESTROYED ON IMPACT AND BOTH PERSONNEL WERE FATALLY WOUNDED FROM BLUNT TRAUMA.  THE TAIL BOOM WAS RECOVERED FROM THE SURFACE AND THE AIRCRAFT WAS RECOVERED FROM THE OCEAN FLOOR.  THE INITIAL ACCIDENT INVESTIGATION SHOWED NO MALFUNCTION WITH THE TAIL ROTOR, THE TAIL ROTOR GEAR BOX, THE ENGINE, ENGINE ACCESSORY GEAR BOX, THE MAIN ROTOR, AND THE TRANSMISSION.  THE SAME COMPONENTS ALSO SHOWED NO SIGNS OF TORSIONAL STRESS.  THE TAIL BOOM DID SHOW SIGNS OF AT LEAST ONE MAIN ROTOR STRIKE AND SEPARATION FROM THE FUSELAGE.

THE AIRCRAFT SUFFERED EXTENSIVE DAMAGE FROM IMPACT AND WAS SCATTERED ALONG THE OCEAN FLOOR WITH ONLY A PARTIAL RECOVERY OF THE AIRCRAFT, LIMITING THE INVESTIGATION.   A SECTION OF THE TAIL BOOM AND TAIL ROTOR DRIVESHAFT COUPLINGS WERE REMOVED AND SENT OFF FOR ANALYSIS BY THE NTSB.  THE CORONER REPORT AND TOXICOLOGY REPORT ARE PENDING. THE INVESTIGATION IS ONGOING.
