AFTER MAKING A LOW PASS OVER A MOUNTAINOUS WORK SITE THE HELICOPTER STARTED A RIGHT TURN. THE PILOT SAID HE SOON REALIZED THAT THE HELICOPTER WOULD NOT BE ABLE TO OUT CLIMB THE STEEP TERRAIN, SO HE STARTED A TURN BACK TO THE LEFT. THEN THE RIGHT SKID HIT THE MOUNTAINSIDE, CAUSING THE SKID AND THE RIGHT HALF OF THE CROSSTUBES TO BE TORN FROM THE AIRFRAME. SOME ADDITIONAL DAMAGE WAS ALSO SUSTAINED BY THE FUSELAGE. THE HELICOPTER RETURNED TO ITS NEARBY BASE CAMP AND LANDED ON A MAKESHIFT SUPPORT STRUCTURE. THE PILOT SAID HE MIGHT HAVE ENCOUNTERED A DOWNDRAFT. THE PILOT AND FOUR PASSENGERS SAID THE WINDS WERE GUSTY AT THE TIME OF THE ACCIDENT.
Probable Cause: THE PILOT'S IMPROPER IN-FLIGHT PLANNING/DECISION, AND HIS DELAY IN TAKING REMEDIAL ACTION. FACTORS WERE THE MOUNTAINOUS TERRAIN AND GUSTY WINDS.
