Narrative:

Air carrier X on wide right base to runway 34L at 11000 ft, heading 270 degrees. We had to make a right turn to 300 degrees to avoid terrain. We did advise ATC after which we were cleared to intercept the localizer back course. We were well west of runway centerline at this time. Approach control frequency was saturated due to numerous light aircraft attempting to land in reno for an small aircraft fly-in. After we intercepted the back course at approximately 9000 ft and 9 DME, we received a sudden TCASII RA which directed us to level off, which we did. We then acquired the small aircraft Y visually and made a left turn to avoid the traffic. Still due to approach control frequency saturation we had to switch to tower on our own and were subsequently cleared to land. We advised our operations supervisor in reno of the event and he informed us that this occurs every yr during the fly-in. It has been reported before with no noticeable effect. NOTAMS should be issued along with warning of possible inbound delays due to airspace saturation.

Title: SMA FLY-IN ACR X TCASII RA WITH SMA Y. EVASIVE ACTION TAKEN. SEE AND AVOID CONCEPT.

Narrative: ACR X ON WIDE R BASE TO RWY 34L AT 11000 FT, HDG 270 DEGS. WE HAD TO MAKE A R TURN TO 300 DEGS TO AVOID TERRAIN. WE DID ADVISE ATC AFTER WHICH WE WERE CLRED TO INTERCEPT THE LOC BACK COURSE. WE WERE WELL W OF RWY CTRLINE AT THIS TIME. APCH CTL FREQ WAS SATURATED DUE TO NUMEROUS LIGHT ACFT ATTEMPTING TO LAND IN RENO FOR AN SMA FLY-IN. AFTER WE INTERCEPTED THE BACK COURSE AT APPROX 9000 FT AND 9 DME, WE RECEIVED A SUDDEN TCASII RA WHICH DIRECTED US TO LEVEL OFF, WHICH WE DID. WE THEN ACQUIRED THE SMA Y VISUALLY AND MADE A L TURN TO AVOID THE TFC. STILL DUE TO APCH CTL FREQ SATURATION WE HAD TO SWITCH TO TWR ON OUR OWN AND WERE SUBSEQUENTLY CLRED TO LAND. WE ADVISED OUR OPS SUPVR IN RENO OF THE EVENT AND HE INFORMED US THAT THIS OCCURS EVERY YR DURING THE FLY-IN. IT HAS BEEN RPTED BEFORE WITH NO NOTICEABLE EFFECT. NOTAMS SHOULD BE ISSUED ALONG WITH WARNING OF POSSIBLE INBOUND DELAYS DUE TO AIRSPACE SATURATION.
