Narrative:
I was inbound from the northwest to land at skyhaven airport in small aircraft X. At 10 mi out I called for airport advisory. After 2 tries I got a very weak reply that 18 was the active. I reported entering a left upwind for 18. I was looking at runway for traffic. About that time I looked up to see an small aircraft Y above and to my left. We both made a right turn at that time. I left the pattern and called unicom to verify the pattern at sky haven airport and was told 18 has right traffic, so I reentered, landed without incident. I asked the man at the counter if he knew there were other aircraft in the pattern and he said yes, there were 2 training aircraft in the pattern without radios. The unicom operator could be a big assistance by advising approaching aircraft when 'right traffic' is in use and that 'no radio aircraft' are in the pattern.

Title: LIGHT ACFT HAS NMAC WITH ANOTHER LIGHT ACFT WHILE EXECUTING A NONSTANDARD PATTERN ENTRY AT AN UNCONTROLLED ARPT.
Narrative: I WAS INBND FROM THE NW TO LAND AT SKYHAVEN ARPT IN SMA X. AT 10 MI OUT I CALLED FOR ARPT ADVISORY. AFTER 2 TRIES I GOT A VERY WEAK REPLY THAT 18 WAS THE ACTIVE. I REPORTED ENTERING A LEFT UPWIND FOR 18. I WAS LOOKING AT RWY FOR TFC. ABOUT THAT TIME I LOOKED UP TO SEE AN SMA Y ABOVE AND TO MY LEFT. WE BOTH MADE A RIGHT TURN AT THAT TIME. I LEFT THE PATTERN AND CALLED UNICOM TO VERIFY THE PATTERN AT SKY HAVEN ARPT AND WAS TOLD 18 HAS RIGHT TFC, SO I REENTERED, LANDED WITHOUT INCIDENT. I ASKED THE MAN AT THE COUNTER IF HE KNEW THERE WERE OTHER ACFT IN THE PATTERN AND HE SAID YES, THERE WERE 2 TRAINING ACFT IN THE PATTERN WITHOUT RADIOS. THE UNICOM OPERATOR COULD BE A BIG ASSISTANCE BY ADVISING APCHING ACFT WHEN 'RIGHT TFC' IS IN USE AND THAT 'NO RADIO ACFT' ARE IN THE PATTERN.
