Narrative:

While flying an unfamiliar plane with no microphone on a rough day (something which does not show good judgement), I did not allow enough sep for the aircraft on final in front of me. During my go around I was too busy flying the airplane to worry about all the other things a pilot has to worry about. At pattern altitude about midway down the runway, I heard an small transport call turning upwind, looked up, and saw that he was pealing off to his right in order to avoid me. If not for his evasive action, there would have been a mid-air. Callback conversation with reporter revealed following information. Reporter states second aircraft made a cross wind pattern entry without a call on unicom. First contact was when pilot called turning upwind which was the evasive maneuver to avoid reporter's aircraft.

Title: NMAC AT UNCONTROLLED ARPT TRAFFIC PATTERN.

Narrative: WHILE FLYING AN UNFAMILIAR PLANE WITH NO MIC ON A ROUGH DAY (SOMETHING WHICH DOES NOT SHOW GOOD JUDGEMENT), I DID NOT ALLOW ENOUGH SEP FOR THE ACFT ON FINAL IN FRONT OF ME. DURING MY GO AROUND I WAS TOO BUSY FLYING THE AIRPLANE TO WORRY ABOUT ALL THE OTHER THINGS A PLT HAS TO WORRY ABOUT. AT PATTERN ALT ABOUT MIDWAY DOWN THE RWY, I HEARD AN SMT CALL TURNING UPWIND, LOOKED UP, AND SAW THAT HE WAS PEALING OFF TO HIS RIGHT IN ORDER TO AVOID ME. IF NOT FOR HIS EVASIVE ACTION, THERE WOULD HAVE BEEN A MID-AIR. CALLBACK CONVERSATION WITH RPTR REVEALED FOLLOWING INFO. RPTR STATES SECOND ACFT MADE A CROSS WIND PATTERN ENTRY WITHOUT A CALL ON UNICOM. FIRST CONTACT WAS WHEN PLT CALLED TURNING UPWIND WHICH WAS THE EVASIVE MANEUVER TO AVOID RPTR'S ACFT.
