Narrative:

We were in right hand pattern after touch-and-go landing on runway 17R. On entering downwind leg the PIC, flying from left seat, requested clearance to land full stop. Controller approved landing. Before turning onto base leg, tower advised that we were cleared to land #2 after aircraft on short final. PIC acknowledged. (At this time PIC indicated to me he had aircraft on short final.) as PIC turned short final and was lining up for runway 17L, tower called unknown aircraft questioning whether it was landing on runway 17L. Tower then talked to a second aircraft apparently on longer final approach to runway 17L to say an aircraft cut them off and recommending they use s-turns for spacing. That pilot asked approval to go around. After we landed, tower advised PIC that he was approved for runway 17R. The PIC stated that he understood he was approved to land on runway 17L. The confusion came about because the tower controller did not specifically state which parallel runway that we were cleared for and PIC did not question the tower since he understood he was cleared for full stop landing on the long runway, runway 17L. As passenger, I was not clear about which runway we were cleared to land on. The second aircraft apparently was able to see a conflict arising and go around.

Original NASA ASRS Text

Title: PRIVATE PLT OF AN SMA SEL ACFT LANDED ON THE WRONG PARALLEL RWY DUE TO A MISUNDERSTANDING BTWN THE PLT AND THE CTLR.

Narrative: WE WERE IN R HAND PATTERN AFTER TOUCH-AND-GO LNDG ON RWY 17R. ON ENTERING DOWNWIND LEG THE PIC, FLYING FROM L SEAT, REQUESTED CLRNC TO LAND FULL STOP. CTLR APPROVED LNDG. BEFORE TURNING ONTO BASE LEG, TWR ADVISED THAT WE WERE CLRED TO LAND #2 AFTER ACFT ON SHORT FINAL. PIC ACKNOWLEDGED. (AT THIS TIME PIC INDICATED TO ME HE HAD ACFT ON SHORT FINAL.) AS PIC TURNED SHORT FINAL AND WAS LINING UP FOR RWY 17L, TWR CALLED UNKNOWN ACFT QUESTIONING WHETHER IT WAS LNDG ON RWY 17L. TWR THEN TALKED TO A SECOND ACFT APPARENTLY ON LONGER FINAL APCH TO RWY 17L TO SAY AN ACFT CUT THEM OFF AND RECOMMENDING THEY USE S-TURNS FOR SPACING. THAT PLT ASKED APPROVAL TO GAR. AFTER WE LANDED, TWR ADVISED PIC THAT HE WAS APPROVED FOR RWY 17R. THE PIC STATED THAT HE UNDERSTOOD HE WAS APPROVED TO LAND ON RWY 17L. THE CONFUSION CAME ABOUT BECAUSE THE TWR CTLR DID NOT SPECIFICALLY STATE WHICH PARALLEL RWY THAT WE WERE CLRED FOR AND PIC DID NOT QUESTION THE TWR SINCE HE UNDERSTOOD HE WAS CLRED FOR FULL STOP LNDG ON THE LONG RWY, RWY 17L. AS PAX, I WAS NOT CLEAR ABOUT WHICH RWY WE WERE CLRED TO LAND ON. THE SECOND ACFT APPARENTLY WAS ABLE TO SEE A CONFLICT ARISING AND GAR.
