SMA UNAUTH PENETRATION OF CLASS C AIRSPACE HAD CONFLICT WITH ACR X EVASIVE ACTION TAKEN.

Narrative

ACR X ON A VECTOR FROM APCH CTL; SAW A MOONEY WITH A BLUE TAIL AT 10-11 O'CLOCK AT APPROX THE SAME ALT; FLYING ON A CONVERGING COURSE. THE ACFT PERFORMED WHAT APPEARED TO A 'WING-OVER' MANEUVER WHICH CAUSED HIM TO LOSE ALT FAST ENOUGH TO PASS UNDER US. I BELIEVE THE ACFT PASSED WITHIN SEVERAL 100 YARDS HORIZLY AND A FEW 100 FT VERTLY. HAD HE NOT TAKEN EVASIVE ACTION; I BELIEVE I COULD HAVE AVOIDED HIM BY MAKING A RAPID EVASIVE MANEUVER. THE ACFT APPARENTLY BELONGED TO A FLT SCHOOL WHICH IS LOCATED AT DAB. THE CTLR APPEARED TO BE SATURATED. I HAD HEARD XMISSIONS BTWN A PLT (IT SEEMED PROBABLE THAT ENGLISH WAS NOT HIS FIRST LANGUAGE) AND THE APCH CTLR WHICH INDICATED THAT THE PLT HAD BEEN DIRECTED TO STAY OUT OF THE CLASS C AIRSPACE. IT ALSO APPEARED THAT THE PLT HAD IDENTED HIMSELF AS 'MOONEY N--' AND LATER USING A FLT SCHOOL CALL SIGN. THE SAME VOICE INDICATED HE HAD MY ACFT (BY COMPANY NAME) IN SIGHT AFTER HE PASSED UNDER US. THERE IS NO DOUBT IN MY MIND THAT HAD WE HAD TCASII (EVEN TCASI) WE WOULD HAVE SEEN THIS ACFT SOONER. WE HAD COMPLETED A TURN TO A NORTHERLY HDG JUST PRIOR TO ENCOUNTERING THE ACFT.
