IFR C172 EXPERIENCED NMAC WITH MOONEY DURING DSCNT INTO PRC DURING FREQ CHANGE FROM ZAB.

Narrative

I WAS DSNDING FROM IFR CRUISING ALT AFTER HAVING SWITCHED FROM ZAB TO PRESCOTT TWR; CLRED FOR A VISUAL APCH INTO PRC. MY ACFT WAS NO LONGER ON AN AIRWAY; AS I WAS HEADING IN THE APPROX DIRECTION OF THE ACTIVE RWY; 3L/R. AS I DSNDED; I LOOKED OUT THE R FRONT AND R PAX WINDOW; WHERE I SAW AN ACFT NOT MOVING IN THE SKY. KNOWING THAT A STILL ACFT IS ANALOGOUS TO COLLISION COURSE; I IMMEDIATELY PULLED SHARPLY UP ON MY ACFT; TRADING MY DSCNT AIRSPD FOR AS MUCH ALT AS POSSIBLE. I REDUCED MY CLB ANGLE AS THE STALL WARNING SOUNDED; AND MY AIRSPD REMAINED APPROX VX (68 MPH). MY EVASIVE MANEUVER INCLUDED A TURN TO THE L; WHICH IN HINDSIGHT SHOULD HAVE BEEN IN THE OTHER DIRECTION; HOWEVER THE MINDSET OF HAVING A COLLISION CTLED MY ACTIONS FOR THE MOST PART. AS THE SEPARATION OF OUR ACFT RESUMED A SAFE DISTANCE; I LOOKED AT THE ACFT AND NOTED THAT HE PROBABLY HAD NOT SEEN ME AT ALL; HE WAS ON THE SAME HEADING AND ALT AS HE WAS WHEN I MANEUVERED MY ACFT AWAY FROM HIM. MY PAX; A RATED PVT PLT; DID NOT NOTICE ANYTHING UNTIL I LOUDLY EXCLAIMED 'TFC' AND SOME OTHER WORDS DUE TO MY SURPRISE (WHILE I MANEUVERED). I DON'T THINK THE PLT OF THE OTHER ACFT WAS SCANNING FOR TFC; AND THOUGH I HAD MY EYES OUTSIDE OF THE WINDOW; I WASN'T ACTIVELY SEEKING TO FIND ANY TFC MYSELF. IT JUST HAPPENED THAT AS I GLANCED OVER IN THE DIRECTION OF MY R WING THAT I SAW THAT ACFT. HOWEVER; I FELT THAT MY TRAINING WAS ADEQUATE FOR THE SIT; AS EVEN WHILE WE WERE IFR; AND NEXT; VFR; I HAD MY HEAD OUTSIDE. BECAUSE THE INCIDENT HAPPENED RIGHT AFTER WE SWITCHED FROM ZAB AND WERE NOT IN DIRECT RADIO CONTACT WITH PRC TWR; I WOULD THINK THAT IT MAY HAVE BEEN A GOOD IDEA TO GO BACK TO CTR AND LET THEM KNOW WHAT HAPPENED. HOWEVER; ONCE I WAS IN RADIO CONTACT WITH PRC I INQUIRED ABOUT THE OTHER ACFT. AS FAR AS IMPROVEMENTS; I THINK PLTS SHOULD BE MORE ENCOURAGED TO AT LEAST MONITOR IF NOT BE IN RADIO CONTACT WITH THE CTLING AGENCY TO HELP WITH TFC SITS.
