THE HELICOPTER WAS OPERATED BY AIR LOGISTICS OF ALASKA INC., FAIRBANKS, ALASKA. THE COMMERCIAL CERTIFICATED PILOT, AND THE SOLE PASSENGER, WERE NOT INJURED. VISUAL METEOROLOGICAL CONDITIONS PREVAILED. A VFR FLIGHT PLAN WAS FILED. DURING A TELEPHONE CONVERSATION WITH THE NATIONAL TRANSPORTATION SAFETY BOARD (NTSB) INVESTIGATOR-IN-CHARGE (IIC), ON JULY 24, THE DIRECTOR OF OPERATIONS FOR THE OPERATOR REPORTED THE PILOT DEPARTED A SURVEY CAMP AREA KNOWN AS HAPPY VALLEY, LOCATED ABOUT 20 MILES SOUTH OF DEADHORSE ALONG THE SAGAVANIRKTOK RIVER, ON A FLIGHT TO SURVEY POTENTIAL EXPLORATION SITES.
