Narrative:

I was transitioning through the class D surface area from 10 mi southwest of redding municipal to enterprise. Approximately 3 mi south of enterprise I was released from the tower frequency. I changed to enterprise CTAF (122.8). After testing and scanning visually I announced a final approach to runway 34 enterprise. 1 mi out on final I observed a cessna 172 crossing my path from west to east. I aircraft was at my same altitude approximately 400 ft or less ahead. I continued my approach and landed. Attempts to contact the aircraft on 122.8 and 122.25 met with negative results. 10 mins later at my tie down I heard the 172 identify and announce a spiral approach. He said that he thought he had his radio on 122.8 but did not. I dropped the matter. On to another day of flying.

Title: SMA LNDG AT NON TWR ARPT HAS NMAC IN PATTERN, ON FINAL.

Narrative: I WAS TRANSITIONING THROUGH THE CLASS D SURFACE AREA FROM 10 MI SW OF REDDING MUNICIPAL TO ENTERPRISE. APPROX 3 MI S OF ENTERPRISE I WAS RELEASED FROM THE TWR FREQ. I CHANGED TO ENTERPRISE CTAF (122.8). AFTER TESTING AND SCANNING VISUALLY I ANNOUNCED A FINAL APCH TO RWY 34 ENTERPRISE. 1 MI OUT ON FINAL I OBSERVED A CESSNA 172 XING MY PATH FROM W TO E. I ACFT WAS AT MY SAME ALT APPROX 400 FT OR LESS AHEAD. I CONTINUED MY APCH AND LANDED. ATTEMPTS TO CONTACT THE ACFT ON 122.8 AND 122.25 MET WITH NEGATIVE RESULTS. 10 MINS LATER AT MY TIE DOWN I HEARD THE 172 IDENT AND ANNOUNCE A SPIRAL APCH. HE SAID THAT HE THOUGHT HE HAD HIS RADIO ON 122.8 BUT DID NOT. I DROPPED THE MATTER. ON TO ANOTHER DAY OF FLYING.
