HELI TAXIING TO PARKING HOVERS 15 FT ABOVE DEPARTING AIR CARRIER.

Narrative

WHILE TAXIING FROM THE GLACIER PARK INTL TERMINAL FOR TKOF ON RWY 20; A HELI WAS OBSERVED APCHING THE ARPT CENTER FROM THE W AT APPROX 25 FT AGL. THE HELI TURNED SBOUND OVER THE RWY AND DISAPPEARED FROM MY FIELD OF VIEW. OUR TAXI; TKOF AND CLBOUT WAS NORMAL. WHILE ENRTE I WAS ADVISED TO CONTACT OUR RAMP IN KALISPELL UPON ARR TO DISCUSS AN INCIDENT THAT OCCURRED ON THE AND IN KALISPELL. RAMP PERSONNEL ADVISED ME THAT THE HELI THAT I HAD OBSERVED WHILE TAXIING HAD TURNED IN BEHIND MY ACFT AND HOVERED EXTREMELY CLOSE TO THE TAIL SECTION OF MY LGT. THE HELI THEN FLEW DIRECTLY OVER THE FUSELAGE AT ABOUT 15 FT ABOVE THE LGT AND HOVERED TO PARKING. THIS MANEUVER WAS UNNECESSARY AND NEEDLESSLY PLACED ACFT; PAXS; AND CREW IN DANGER. THE INCIDENT REFLECTED POOR JUDGEMENT ON THE PART OF THE HELI PLT BUT MORE IMPORTANTLY OPERATING LARGE AIRLINERS INTO UNCTLED ARPT A POOR FAA POLICY. RULES ALLOWING THESE TYPES OF OPERATION ASSUMES THAT ALL PLTS OPERATE WITH THE SAME CAUTION AND PROFESSIONALISM EXHIBITED IN THE ORDERLY PROCS FOUND IN A CTLED ENVIRONMENT. THIS IS NOT REALITY. YRS OF OPERATING IN THESE UNCTLED ARPTS HAS TAUGHT ME TO EXPECT THE UNEXPECTED AND REALIZE THAT A DISASTER IS SURE TO OCCUR DUE TO OPERATION IN THIS UNCTLED ENVIRONMENT. I RECOMMEND THAT THE FAA PLACE A CTL TWR AT ALL ARPTS SERVED BY PART 121 CARRIERS. THE PAXS PAY A TICKET TAX FOR AND DESERVE THE PROTECTION THAT A CTLED ENVIRONMENT PROVIDES.
