POTENTIAL CONFLICT LTSS IN AN OPPOSITE DIRECTION TFC SITUATION IN PROX OF ATA.

Narrative

DURING CLBOUT ON A 'DUMBARTON L' (PAO L STANDARD DEP TO SW) DEP AT ABOUT 90 KIAS; THROUGH 1500 FT W OF HIGHWAY 101; WE (CFI STUDENT AND MYSELF; CFI) HEARD AN OLD MTR RPT INBOUND FOR LNDG OVER STANFORD UNIVERSITY WHILE ON TWR FREQ (118.6). THE TWR WAS BUSY AND DID NOT RESPOND TO THE CALL. SINCE WE WERE APCHING STANFORD (HDG ABOUT 200 DEG) AND WERE WITHIN A MI OF WHERE THE ACFT RPTED; WE IMMEDIATELY LOOKED FOR THE TFC. THE MTR WAS OVER STANFORD CAMPUS HDG STRAIGHT AT US (ON HDG 020 DEG). WE WERE CLBING THROUGH 1700 FT AND THE OTHER ACFT APPEARED TO BE DSNDING THROUGH 2000 FT. OUR DISTANCE WAS LESS THAN A MI; NOW; AND CLOSING RAPIDLY. PER AIM PROCS; WE TURNED R IMMEDIATELY AND THE OTHER ACFT TURNED L. CONTACT WAS IMMINENT. WITH LESS THAN 1/4-1/8 MI WE CUT PWR; BANKED SHARPLY (45-60 DEG) TO THE L WHILE DSNDING. THE MTR MUST HAVE FINALLY SEEN US SINCE NO CONTACT WAS MADE. WHEN WE COMPLETED A 360 DEG TURN WE SAW THE OTHER ACFT IN A L CIRCLING TURN OVER STANFORD. HE MADE A SECOND CALL TO PAO TWR AND WAS TOLD TO 'STAND BY'. I RPTED THE NEAR MISS TO TWR; IMMEDIATELY; ON 118.6; IDENTING THE OTHER ACFT AS THE MTR. THAT ACFT WAS ABOUT 2 MI 'INSIDE' PAO ATA WHEN HE FIRST CALLED IN. HE CONTINUED INBOUND WITH NO ATC ACKNOWLEDGEMENT. WE CALLED PAO GND CTL WHILE AIRBORNE OUTSIDE PAO ATA AND ASKED; AFTER THE MTR LANDED AND WAS TAXIING BACK TO THE HANGAR; TO HAVE THE PLT CALL US AT OUR FLYING CLUB. GND CTL RELAYED OUR MESSAGE TO THE PLT. THE PLT RESPONDED SARCASTICALLY; 'YEAH; RIGHT!. I RPTED THE NEAR MISS IN WAITING AT PAO TWR AND IT WAS SENT TO FSDO (SJC). THE MTR PLT IS A 'PROFESSIONAL' MLG CAPT FOR AN AIRLINE. SUPPLEMENTAL INFO FROM ACN 191586: APCHING PAO I MONITORED LCL FREQ FOR APPROX 5 MINS AND NOTICED VERY BUSY CTLR TRYING TO KEEP UP WITH VOLUME OF ACFT. SOUNDED LIKE SHE MIGHT BE A TRAINEE; CALLED IN OVER STANFORD (NORMAL RPTING POINT) AND GOT NO REPLY (TOO BUSY). CALLED IN AGAIN ENTERING THE ATA AND RECEIVING A 'STAND BY'. STILL VERY BUSY. APCHING THE STANFORD STADIUM MONITORING HOW BUSY THE PATTERN WAS; I BEGAN A RIGHT 360 DEG TURN TO ALLOW THE CTLR TIME TO SEQUENCE ME. NOTICED A HIGH WING SMA ON EITHER L XWIND DEP OR TURNING TO L DOWNWIND. DETERMINED IT WAS NO FACTOR AND CONTINUED 360. IN TURN; HEARD PLT OF OTHER ACFT SAY; 'TWR...I WANT TO RPT A NEAR MIDAIR'. TWR THEN CLRED ME TO ENTER DOWNWIND AND LAND. OTHER PLT STATED A 1/8 MI PASSING DISTANCE. NOT A NEAR MISS IN MY OPINION BUT A CONCERN OF A PLT WHO FLIES A COLLISION COURSE TO THE POINT OF A NEAR MISS IN HIS OPINION. ON THE GND HE SAID TO CTLR HE SAW ME AT 2 MI AND CONTINUED UNTIL HIS EVASIVE MANEUVER AT 1/8 MI. HE SHOULD CHANGE FLT PATH SOONER AND CTLR NOT IGNORE REPEATED XMISSION FROM INBOUND ACFT.
