Narrative:

On final approach to the south to the transient parking ramp; a fast moving; climbing helicopter became visible to my 3 O'clock position from behind a hangar. I decelerated and turned right. Before I could make a radio call over the tower frequency the other pilot performed a quick-stop maneuver and reversed course. I returned to finish my approach on a slightly modified course and taxied back to the company parking area. The operator that I am employed by; the other operator; and our designated FAA poi have discussed the occurrence and made procedural changes. We hope that these changes--now in effect--will prevent a similar occurrence in the future. The new procedure includes an additional radio call to alert helicopters in take-off position of an aircraft on base turn; and a different approach course to increase visibility for one aircraft to see the other from either side of the hangar (per mccarran tower LOA; radio calls between aircraft are allowed to aid in maintaining adequate separation).
