Narrative:

I was flying GA twin X. Was on vector 120 degree for visual approach runway 7. Saw runway and was cleared for approach and changed to tower frequency. Tower said cleared to land. As I began turn to final my two passenger in right seats yelled about traffic off to right side. I levelled wings saw aircraft Y and made hard left turn to avoid collision. Tower warned us about aircraft Y after we had already taken evasive action. Tower then said to parallel final and we would land ahead of Y. Tower also advised us of departure aircraft Z. We saw small jet Z pass about 500' below and behind us. I maintained 2000' as I thought there may be more departure aircraft where aircraft Z came from. My passenger kept aircraft Y in sight as it continued straight in for runway 7. At about two mi I told tower that we were still abeam aircraft Y, and asked how we were both to land on same runway. Aircraft Y then made first call to tower (garbled). Tower told Y to make 360 to the right and told me to land. I said I would try. At 1/4 mi and 500' I started go around and was told to make tight pattern and landed ok. I feel that small aircraft aircraft Y should not have been on final within an arsa (apparently without radio contact), that I should have looked right before making left turn to final, and that despite the heavy traffic, the tower should have been more concerned with separation and less with expediting traffic. Also I should have refused to attempt landing from 2 miles and 1900', and should have insisted on some resequencing maneuver in order to make normal approach and landing. Callback conversation with reporter has revealed the following information: reporter estimates closest proximity as less than 100' at same altitude. Did not file an FAA near midair collision report as he did not know there was such a report available. Reviewed incident with tower person who brought ASRS form to FSS for him. Does not know if aircraft Y had worked approach control into arsa, but first call tower was at 2 miles. Tower person said they saw aircraft Y on tower radar scope at about the same time as near midair collision occurred.

Title: NMAC BETWEEN GA TWIN AND SMALL GA IN ARSA AIRSPACE AND ON FINAL TO SATELLITE ARPT.

Narrative: I WAS FLYING GA TWIN X. WAS ON VECTOR 120 DEG FOR VISUAL APCH RWY 7. SAW RWY AND WAS CLRED FOR APCH AND CHANGED TO TWR FREQ. TWR SAID CLRED TO LAND. AS I BEGAN TURN TO FINAL MY TWO PAX IN R SEATS YELLED ABOUT TFC OFF TO R SIDE. I LEVELLED WINGS SAW ACFT Y AND MADE HARD L TURN TO AVOID COLLISION. TWR WARNED US ABOUT ACFT Y AFTER WE HAD ALREADY TAKEN EVASIVE ACTION. TWR THEN SAID TO PARALLEL FINAL AND WE WOULD LAND AHEAD OF Y. TWR ALSO ADVISED US OF DEP ACFT Z. WE SAW SMALL JET Z PASS ABOUT 500' BELOW AND BEHIND US. I MAINTAINED 2000' AS I THOUGHT THERE MAY BE MORE DEP ACFT WHERE ACFT Z CAME FROM. MY PAX KEPT ACFT Y IN SIGHT AS IT CONTINUED STRAIGHT IN FOR RWY 7. AT ABOUT TWO MI I TOLD TWR THAT WE WERE STILL ABEAM ACFT Y, AND ASKED HOW WE WERE BOTH TO LAND ON SAME RWY. ACFT Y THEN MADE FIRST CALL TO TWR (GARBLED). TWR TOLD Y TO MAKE 360 TO THE R AND TOLD ME TO LAND. I SAID I WOULD TRY. AT 1/4 MI AND 500' I STARTED GO AROUND AND WAS TOLD TO MAKE TIGHT PATTERN AND LANDED OK. I FEEL THAT SMA ACFT Y SHOULD NOT HAVE BEEN ON FINAL WITHIN AN ARSA (APPARENTLY WITHOUT RADIO CONTACT), THAT I SHOULD HAVE LOOKED R BEFORE MAKING L TURN TO FINAL, AND THAT DESPITE THE HEAVY TFC, THE TWR SHOULD HAVE BEEN MORE CONCERNED WITH SEPARATION AND LESS WITH EXPEDITING TFC. ALSO I SHOULD HAVE REFUSED TO ATTEMPT LNDG FROM 2 MILES AND 1900', AND SHOULD HAVE INSISTED ON SOME RESEQUENCING MANEUVER IN ORDER TO MAKE NORMAL APCH AND LNDG. CALLBACK CONVERSATION WITH RPTR HAS REVEALED THE FOLLOWING INFORMATION: REPORTER ESTIMATES CLOSEST PROX AS LESS THAN 100' AT SAME ALT. DID NOT FILE AN FAA NMAC REPORT AS HE DID NOT KNOW THERE WAS SUCH A REPORT AVAILABLE. REVIEWED INCIDENT WITH TWR PERSON WHO BROUGHT ASRS FORM TO FSS FOR HIM. DOES NOT KNOW IF ACFT Y HAD WORKED APCH CTL INTO ARSA, BUT FIRST CALL TWR WAS AT 2 MILES. TWR PERSON SAID THEY SAW ACFT Y ON TWR RADAR SCOPE AT ABOUT THE SAME TIME AS NMAC OCCURRED.
