AN SMA ATP PLT HAS AN NMAC WITH A C172RG WITH 2 CFI'S ON BOARD AT CCB; CA.

Narrative

CABLE ARPT TFC PATTERN. UNICOM CLOSED. I HAD JUST LEFT THE POC (BRACKETT ARPT) TWR FREQ FOR A XWIND ENTRY TO CCB ARPT RWY 24. I LIKE TO MONITOR CTAF 30 MI OUT; BUT NOT POSSIBLE FROM THIS DIRECTION DUE TO POC TWR. I FLY A 'SHORT PATTERN' WHEN POSSIBLE (TFC PERMITTING) IN ORDER TO STAY WITHIN GLIDING DISTANCE OF THE LNDG RWY. (THAT IS ONE REASON FOR A PATTERN IN THE FIRST PLACE IS IT NOT?) I CALLED XWIND AND DOWNWIND AND FINAL APCH ON MY RADIO. I DID NOT HEAR ANY XMISSIONS FROM ANY OTHER ACFT AND DID NOT SEE THE C172RG UNTIL IT WAS DIRECTLY BELOW ME ON SHORT FINAL. I WENT AROUND MISSING THE C172RG BY A SMALL MARGIN. (I FLY FORMATION ON A REGULAR BASIS AND WE WERE VERY CLOSE.) I SPOKE WITH THE PLTS. BOTH CLAIMED TO BE THE PIC AND BOTH WERE FLT INSTRUCTORS (CFI'S). BOTH HEARD MY XWIND RADIO CALL AND THEN WONDERED WHERE I WAS. ONE SAID 'WE DID FLY A LARGE PATTERN.' BOTH HEARD ME GO AROUND AND THEN ASK THEM FOR A RADIO CHK SO MY RADIO AND THEIRS WERE WORKING. ONLY BETTER SEE AND AVOID EYES COULD HAVE PREVENTED THIS NEAR MISS. ALSO CLASSIC HIGH/LOW WING IN A CTAF TFC PATTERN. I JUST GOT THE BOOK 'AUDITING MIDAIR COLLISIONS.'
