C185 HAS NMAC WITH JETSTREAM ON APCH AT TWR CTLED ARPT.

Narrative

WHILE ON L DOWNWIND FOR RWY 29L AT FRESNO THE TWR ASKED ME TO RPT A JETSTREAM ON A 4 MI STRAIGHT IN FOR THE L. APPROX DOWNWIND ABEAM THE NUMBERS I SAW A JETSTREAM ON ABOUT A 2 MI FINAL; I RPTED 'JETSTREAM IN SIGHT.' THE TWR TOLD ME TO FOLLOW THE JETSTREAM; #2; CLRED TO LAND ON RWY 29L. I TURNED L BASE BEHIND THE JETSTREAM AND WAS SETTING UP FOR LNDG. ABOUT THIS TIME I NOTICED HE WAS NOT LNDG ON THE L; BUT WAS LNDG ON THE R. IMMEDIATELY I STARTED THINKING; IS THERE ANOTHER JETSTREAM OUT HERE? I LOOKED TO THE R AND THERE WAS A JETSTREAM APPROX 500-1000 FT AWAY. I MADE A R TURN AND PASSED TO HIS L SIDE. AT THIS TIME THE TWR ADVISED THE JETSTREAM THAT THERE WAS A CESSNA PASSING BELOW AND OFF TO HIS L. THE JETSTREAM PLT ADVISED; HE HAD ME IN SIGHT AND WAS EXECUTING A MAP. AT THIS TIME THE TWR TOLD ME; I WAS CLRED TO LAND ON THE L; WHICH I DID. I FEEL THAT I SHOULD HAVE BEEN ADVISED THAT THERE WERE 2 JETSTREAMS MAKING STRAIGHT INS FOR THE R AND L SO THAT I COULD HAVE BEEN LOOKING FOR BOTH OF THEM. ALSO I AM WONDERING; WHEN DID THE JETSTREAM PLT SEE ME? AND WHY DIDN'T HE RPT THAT THERE WAS A CESSNA TURNING L BASE IN FRONT OF HIM? THESE THINGS HAPPEN FAST!
