Narrative:

While on left downwind for runway 29L at fresno the tower asked me to report a jetstream on a 4 mi straight in for the left. Approximately downwind abeam the numbers I saw a jetstream on about a 2 mi final, I reported 'jetstream in sight.' the tower told me to follow the jetstream, #2, cleared to land on runway 29L. I turned left base behind the jetstream and was setting up for landing. About this time I noticed he was not landing on the left, but was landing on the right. Immediately I started thinking, is there another jetstream out here? I looked to the right and there was a jetstream approximately 500-1000 ft away. I made a right turn and passed to his left side. At this time the tower advised the jetstream that there was a cessna passing below and off to his left. The jetstream pilot advised, he had me in sight and was executing a map. At this time the tower told me, I was cleared to land on the left, which I did. I feel that I should have been advised that there were 2 jetstreams making straight INS for the right and left so that I could have been looking for both of them. Also I am wondering, when did the jetstream pilot see me? And why didn't he report that there was a cessna turning left base in front of him? These things happen fast!

Title: 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!
