NMAC OF 2 SMA'S IN TFC PATTERN.

Narrative

ACTIVE RWY 22; 2500 FT LONG; L TFC; MOUNTAINS 1 MI S OF ARPT RISING TO OVER 4000 FT; TFC PATTERN ALT 800 FT (ABOUT 600 FT AGL); 5 TO 6 OTHER ACFT IN PATTERN. FIRST TIME FLOWN TO THIS ARPT. 'GAR' FOLLOWING UNSATISFACTORY SIDEWAYS DRIFT OFF RWY SHORTLY BEFORE TOUCHDOWN. REACHED ALT OF 1200 FT MSL IN XWIND LEG AND TURNED XWIND TO DOWNWIND LEG ABOUT 1/2 MI FROM MOUNTAINS AND COMMENCED DSCNT BACK DOWN TO TPA ON COMPLETION OF TURN. 'NEAR MISS' MUST HAVE OCCURRED EITHER DURING THE TURN FROM XWIND TO DOWNWIND OR SHORTLY AFTER. DID NOT SEE THE OTHER ACFT THEN NOR HEAR A RADIO CALL. ONLY HINT THAT A NEAR MISS MIGHT HAVE OCCURRED AT THE TIME WAS SEEING OTHER ACFT (CESSNA 172) OUT OF CORNER OF MY EYE TO THE R JUST AS I TURNED BASE. OTHER ACFT FOLLOWED ME TO LAND SHORTLY AFTER. DO NOT RECALL HEARING ANY RADIO CALL FROM THAT ACFT ANYTIME IN THE PATTERN - WOULD HAVE BEEN OBVIOUS AS IT WAS ONLY CESSNA IN PATTERN AT THE TIME. ONLY LEARNED OF NEAR MISS AFTER LNDG FROM EYE WITNESS ON GND AND THREATS OF PHYSICAL VIOLENCE FROM OTHER PLT. LESSONS LEARNED: BEWARE OF HIGH WING ACFT BELOW LOW WING ACFT. EXTRA VIGILANCE IN BUSY NON-CTLED ARPT. BALANCE ATTN BTWN FLYING ACFT; WATCHING FOR TFC AND TERRAIN AVOIDANCE.
