A LANCAIR IV PLT LANDS AT A CLOSED ARPT AT PVF; CA.

Narrative

1) PLT ERROR. FLEW VFR TO PVF (AN UNCTLED LCL FIELD) FOR AN ADVERTISED PANCAKE BREAKFAST. MADE ROUTINE LNDG; AND IN ROLLOUT WAS ADVISED BY ORGANIZERS ON CTAF THAT I HAD VIOLATED FAR BY LNDG ON FIELD CLOSED BY NOTAM FOR AIRSHOW. NOTHING UNSAFE; DID NOT INTERFERE WITH ANY TFC. PRIMARY CAUSE -- PLT'S FAILURE TO READ NOTAM. LESSON LEARNED. ALWAYS READ NOTAMS. EVEN 'LCL' FIELDS. 2) ORGANIZER'S ERROR. A CONTRIBUTING FACTOR WAS FAILURE TO ADVISE ME ON CTAF THAT ARPT WAS CLOSED; OR TO WARN ME OFF AT ANY POINT IN THE LNDG PATTERN. THERE WAS AMPLE OPPORTUNITY TO DO THIS; AS I DID ASK UNICOM ON CTAF FOR LNDG ADVISORY AT 10 MI OUT AND GOT NO RESPONSE. THIS IS NOT UNUSUAL; SO I CAME IN TO READ THE WINDSOCK; CALLING ON CTAF EACH SEGMENT OF THE PATTERN. XWIND OVER MIDFIELD; DOWNWIND; BASE AND FINAL. NOT UNTIL ROLLOUT DID AN ORGANIZER ADVISE ON CTAF THAT I WAS IN VIOLATION. CONTRIBUTING CAUSE -- SHOW ORGANIZER'S FAILURE TO ADVISE ARPT WAS CLOSED. MY LNDG PATTERN WAS CONVENTIONAL; READILY VISIBLE AND WAS BEING BROADCAST ON CTAF AT ALL TIMES. SUGGESTED CORRECTIVE ACTION -- WHEN SHOW ORGANIZER'S CLOSE A FIELD AND ESTABLISH A TEMPORARY SHOW FREQ; SAFETY WOULD BE ENHANCED IF SOMEONE WERE ASSIGNED TO CONTINUOUSLY MONITOR THE CTAF TO WARN OFF DELINQUENT PLTS SUCH AS ME.
