Factual narrative

THE PLT REPORTED THAT THE HELICOPTER MADE AN UNCOMMANDED TURN TO THE RIGHT AND ROLLED TO THE LEFT AS SHE WAS HOVER-TAXIING AWAY FROM THE HANGAR TOWARD THE TAKEOFF AREA. THE ACFT SUBSEQUENTLY IMPACTED THE TERRAIN AND CAME TO REST ON ITS LEFT SIDE. POST-CRASH EXAM OF THE ACFT REVEALED NO EVIDENCE OF PRE-EXISTING MECHANICAL FAILURE OR MALFUNCTION. INVESTIGATION REVEALED THAT THE WIND AT THE TIME WAS BLOWING FROM 320 DEG AT 15 KTS GUSTING TO 22 KTS, AND THAT THE HELO LIFTOFF POINT WAS ON THE DOWNWIND SIDE OF THE HANGAR. THE FAA BASIC HELICOPTER HANDBOOK AC61-13B NOTES THAT TURBULENCE IS LIKELY TO BE FOUND NEAR THE GROUND OF THE DOWNWIND SIDE OF BLDGS WHENEVER THE WIND VELOCITY EXCEEDS 10 MPH (8.7 KTS).
