Narrative:

I was inbound from ryan field and was in radar contact and radio contact with tus TRACON inbound to tus for a full stop landing. The TRACON controller handed me off to the tower approximately 7 mi wnw of tus at a VFR chkpoint known as the 'jolly green.' I called on the assigned frequency and proceeded with the message, 'tus tower, small aircraft X jolly green, inbound at 4000', landing tus.' the controller in the tower stated on the frequency that I was on, 'small aircraft X, tus tower, proceed right traffic runway 11R at or above 4000'.' I proceeded in and as I was approaching, I heard 'X cleared for 11R.' it did sound faint, but I did acknowledge it 'X.' I began to notice that I could only hear the commercial traffic landing on 11L, but I guessed that there was no air traffic except for me. I found out after the flight that they were using another frequency for the south runway which I was going to land on. So, the TRACON assigned me to the normal tower frequency that the old system used (118.3). 119.0 is hardly ever used up until this point. I couldn't really believe that they did not even think about calling me on the frequency I was on. The tower was wrong in thinking that my radio was out. It should be remarked that in this incident, ATC was at fault and that any reasonable pilot would have performed the same way in this situation since it was unaware that there was a second frequency being used at the time.

Title: SMT PLT COMPLAINS OF IMPROPER COM PROC WHEREIN 2 TWR FREQ WERE IN USE AND HE WAS ASSIGNED THE ONE FOR THE OTHER PARALLEL RWY. LANDED UNKNOWINGLY WITHOUT CLRNC TO LAND.

Narrative: I WAS INBND FROM RYAN FIELD AND WAS IN RADAR CONTACT AND RADIO CONTACT WITH TUS TRACON INBND TO TUS FOR A FULL STOP LNDG. THE TRACON CTLR HANDED ME OFF TO THE TWR APPROX 7 MI WNW OF TUS AT A VFR CHKPOINT KNOWN AS THE 'JOLLY GREEN.' I CALLED ON THE ASSIGNED FREQ AND PROCEEDED WITH THE MESSAGE, 'TUS TWR, SMA X JOLLY GREEN, INBND AT 4000', LNDG TUS.' THE CTLR IN THE TWR STATED ON THE FREQ THAT I WAS ON, 'SMA X, TUS TWR, PROCEED RIGHT TFC RWY 11R AT OR ABOVE 4000'.' I PROCEEDED IN AND AS I WAS APCHING, I HEARD 'X CLRED FOR 11R.' IT DID SOUND FAINT, BUT I DID ACKNOWLEDGE IT 'X.' I BEGAN TO NOTICE THAT I COULD ONLY HEAR THE COMMERCIAL TFC LNDG ON 11L, BUT I GUESSED THAT THERE WAS NO AIR TFC EXCEPT FOR ME. I FOUND OUT AFTER THE FLT THAT THEY WERE USING ANOTHER FREQ FOR THE S RWY WHICH I WAS GOING TO LAND ON. SO, THE TRACON ASSIGNED ME TO THE NORMAL TWR FREQ THAT THE OLD SYS USED (118.3). 119.0 IS HARDLY EVER USED UP UNTIL THIS POINT. I COULDN'T REALLY BELIEVE THAT THEY DID NOT EVEN THINK ABOUT CALLING ME ON THE FREQ I WAS ON. THE TWR WAS WRONG IN THINKING THAT MY RADIO WAS OUT. IT SHOULD BE REMARKED THAT IN THIS INCIDENT, ATC WAS AT FAULT AND THAT ANY REASONABLE PLT WOULD HAVE PERFORMED THE SAME WAY IN THIS SITUATION SINCE IT WAS UNAWARE THAT THERE WAS A SECOND FREQ BEING USED AT THE TIME.
