LTSS -- GA PLT IS ALMOST HIT BY ANOTHER ON THE SAME AIRWAY AND AT THE SAME ALT.

Narrative

THE FOLLOWING IS A NARRATIVE OF A NMAC WITH AN ACFT FLYING AT THE SAME VFR ALT. THE RPTR OF THIS EVENT WAS FLYING A WHITE/RED CESSNA 182 WITH 2 PAX. JUST PRIOR TO ROLLING ONTO RWY 12 AT WENDOVER; UT; I HEARD A DC9 CALLING WENDOVER TFC FOR ADVISORIES. SINCE I DIDN'T HEAR HIS POS; I CALLED THE DC9 FOR A POS AND HE ADVISED ME THAT HE WAS 30 MI OUT. WE PROCEEDED TO DEPART ON RWY 12 AND JUST AFTER LIFTOFF AS WE WERE DEPARTING THE ARPT TFC PATTERN (XA15 HRS); WE HEARD A CESSNA XXX CALL 'WENDOVER TFC' ON 122.8 ADVISING HE WAS 7 MI E AT 7500 FT. WE ANNOUNCED THAT WE WERE EBOUND; CLBING THROUGH 5800 FT. WE THEN HEARD A ? TWIN CALL WENDOVER UNICOM FOR ADVISORIES; WHICH HE RECEIVED. AT THIS POINT I ADVISED MY PAX TO WATCH CAREFULLY FOR TFC; THAT 2 ACFT WERE RPTING CLOSE TO US. WE SAW THE LIGHT TWIN PASS 1/4 MI TO OUR R AND UNDER US AT ABOUT 6 NM E OF WENDOVER. (THE TWIN WAS AT ABOUT 5500 FT AND WE WERE AT 6800 FT). AFTER PASSING THE 7 NM POINT WE PROCEEDED TO CLB TO 7500 FT AND WERE LEVEL AT 7500 PASSING OVER THE BONNEVILLE VOR EBOUND ON V32. APPROX 15 NM E OF BVL VOR AT ABOUT XA28 HRS A WHITE AND RED CESSNA (182) ACFT; WBOUND AT 7500 FT TURNED FROM HIS R TO L DIRECTLY IN FRONT OF US. THE CESSNA WAS INITIALLY ABOUT 500-800 FT WHEN HE TURNED; WITH THE CLOSEST POINT BEING ABOUT 300 FT JUST AHEAD AND TO THE R OF OUR R WING. THE CESSNA SAW US FIRST; BECAUSE WE DID NOT SEE HIM UNTIL HE HAD STARTED HIS TURN IN FRONT OF US. WE HEARD THE SAME CESSNA XXX LNDG AT WENDOVER ABOUT 10 MIN LATER. MAR/XX/95: THE PLT OF XXX; CALLED ME ON MAR/XX/95 TO FIND OUT IF WE HAD SEEN HIM AND TO RPT HE HAD HEARD THE CONVERSATION BTWN US AND THE DC9; AND BEING CONCERNED ABOUT THE DC9 BEING IN THE AREA WAS DSNDING FROM 8500 FT WHEN HIS PAX OBSERVED US AND HE TOOK EVASIVE ACTION TO HIS L. THE PLT OF XXX SAID HE TURNED L BECAUSE HE WAS CLOSER TO OUR R SIDE AND THAT WAS THE QUICKEST WAY OUT. THE PLT OF XXX STATED HE AND HIS PAX WERE ALSO WATCHING FOR OUR TFC AND APOLOGIZED FOR ANY SCARE HE MAY HAVE CAUSED. HE ALSO FELT THAT HE WAS CLOSER THAN THE 300 FT WHICH I FELT WAS THE CLOSEST HE CAME TO US. MY ESTIMATE IS BASED ON XXX BEING ABOUT 10 WING SPANS FROM US AT THE CLOSEST POINT; JUST OFF OUR R WING. CORRECTIVE ACTIONS: I FEEL BOTH CREWS WERE ALERT AND WATCHING FOR THE OTHER; BUT IN RETROSPECT SHOULD HAVE TRIED TO ASCERTAIN EACH OTHER'S POS BY RADIO EVEN THOUGH THERE WAS QUITE A BIT OF RADIO TFC. I KNOW I WILL BE CALLING MORE PLTS FOR POS RPT UPDATES.
