THE FLIGHT WAS DELAYED BECAUSE OF A FOG LAYER AT THE AIRPORT. ACCORDING TO WITNESSES AT THE AIRPORT, THE HELICOPTER DEPARTED WITHOUT INCIDENT. A MINUTE INTO THE FLIGHT THEY HEARD THE PILOT, ALSO A HELICOPTER CFI, SAY, 'HEY! I'VE GOT A...'. NO OTHER RADIO TRANSMISSIONS WERE HEARD. A WITNESS LOCATED NEAR THE ACCIDENT SITE RECALLED WATCHING THE HELICOPTER FISHTAIL, AND HEARD A SPUTTERING SOUND COMING FROM THE HELICOPTER. RADAR DATA DEPICTED THE HELICOPTER AT 700 FT MSL, FLYING IN AN EASTERLY DIRECTION, AND THEN REVERSE COURSE TO A WESTERLY HEADING, WITHIN 23 SECS OF COVERAGE. THE MAIN FUSELAGE IMPACTED THE GROUND IN A WOODED AREA; OTHER DEBRIS FROM THE HELICOPTER WAS SCATTERED OVER AN AREA 800 FEET LONG AND 100 FEET WIDE. A POST IMPACT FIRE FURTHER DAMAGED THE AIRFRAME. EXAMINATION OF THE SEPARATED TAILCONE AND FUSELAGE COMPONENTS SHOWED EVIDENCE OF INFLIGHT MAIN ROTOR BLADE CONTACT; THE WRECKAGE EXAMINATION ALSO SHOWED SIGNS OF MAST BUMPING.
Probable Cause: DIVERGENCE OF THE MAIN ROTOR FROM ITS NORMAL PLANE OF ROTATION FOR AN UNDETERMINED REASON(S) RESULTING IN ROTOR BLADE CONTACT WITH THE TAILCONE.
