THE FLT HAD DEPARTED THE NORTH CAROLINA BAPTIST HOSPITAL IN WINSTON SALEM. IT ARRIVED FROM THE NE AND WAS VECTORED FOR THE ILS RWY 23 APCH. THE LAST VECTOR WAS 240 DEG, WHICH WAS INADEQUATE TO INTERCEPT THE LCLZ. THE PLT WAS CLEARED FOR AND INSTRUCTED TO MAINTAIN 7000 FT UNTIL ESTABLISHED ON THE APCH. RECORDED RADAR DATA SHOWS THE FLIGHT DID NOT INTERCEPT THE LCLZ BUT PARALLELED ON A SW COURSE, A MILE LEFT OF THE LCLZ, WHILE MAINTAINING 7000 FT. THE FLT CONTINUED THIS COURSE UNTIL ABEAM OF THE RWY DEPARTURE END, BEGAN TO DESCEND, TURNED NW, CROSSED THE EXTENDED RWY CENTLERLINE, AND THEN PROCEEDED OUTBOUND FROM THE RWY ON APRX 230 DEG COURSE UNTIL THE LAST RECORDED POSITION ABOUT 5 MI SW OF THE ARPT AT 4100 FT ALTITUDE. THE ACCIDENT SITE WAS ON A MOUNTAIN ABOUT 7.5 MI SW OF THE ARPT AT 3400 FT MSL. A WITNESS REPORTED THAT BEFORE HE HEARD THE CRASH HE COULD NOT SEE THE ACFT BECAUSE THE MOUNTAIN WAS OBSCURED BY FOG. BOTH NAV RADIOS WERE SET TO THE LCLZ FREQ. THE PUBLISHED IAP SHOWS A GLIDESLOPE INTERCEPT ALT OF 5000 FT, AND THE DH WAS 3157 FT. ACFT WAS OPERATED BY AIR METHODS CORPORATION.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

THE PILOT'S FAILURE TO INTERCEPT THE FINAL APPROACH COURSE, AND HIS IMPROPER EXECUTION OF THE INSTRUMENT APPROACH PROCEDURE. FACTORS WHICH CONTRIBUTED TO THE ACCIDENT WERE: THE WEATHER CONDITIONS, AND THE FAILURE OF THE AIR TRAFFIC CONTROLLER TO ADEQUATELY VECTOR THE FLIGHTCREW TO INTERCEPT THE FINAL APPROACH COURSE AT THE APPROACH GATE, AS SPECIFIED IN THE ATC HANDBOOK.
