NMAC BETWEEN ACR-LGT AND MLT.

Narrative

AN MLT ON A TKOF OR GO AROUND FROM THE NW RWY AT FAIRCHILD AFB PASSED DIRECTLY UNDER MY ACFT WHILE ON A LEFT HAND VISUAL APCH TO GEG RWY 3. THIS TFC PASSED ABOUT 100' UNDER OUR FLT PATH WITH A MAX SEP OF ABOUT 300'. APCH CTL ONLY GAVE US TFC FOR GEG RWY 3 AS AN LTT WHO WOULD CIRCLE AND LAND ON RWY 25. NO MENTION OF THE MLT BY APCH OR TWR. WE TOLD THE TWR OF THE NEAR MISS AND ON THE GND TWR ADVISED US THAT EVERYONE HAD US IN SIGHT. THE LTT WAS ABSOLUTELY NO FACTOR FOR OUR APCH. I HAVE COMPLAINED IN THE PAST TO GEG APCH CTL ABOUT MIXING UP FAIRCHILD AND GEG PATTERNS AND HAVE SUGGESTED THAT ALL CIRCLING APCHS TO RWYS 3 AND 7 BE RIGHT HAND FROM THE S SIDE OF THE ARPT. THIS WAS VERY SLOPPY AND INADEQUATE ATC HANDLING AND ALMOST RESULTED IN A MAJOR DISASTER. CALLBACK CONVERSATION WITH RPTR ACN 97522: ASCERTAINED THE LGT WAS DIRECTLY OVER SKA HDG SBND ON BASE. HAD SEEN THE MLT ON APCH TO RWY 5 AT SKA BUT THEN HAD DIRECTED ATTN TO SIGHTING LTT GIVEN AS TFC TO FOLLOW. FIGURES MLT MADE MISSED APCH AND PULLED UP TOO FAST CAUSING THE NMAC ALTHOUGH TWR DID RPT MLT HAD LGT IN SIGHT. STATED GEG DOES SOMETIMES USE RIGHT DOWNWIND FOR RWY 3 OPERATION BUT NOTHING STANDARD. ASCERTAINED RPTR'S CERTIFICATES AND FLT TIME.
