Narrative:
While descending to 10000 controller gave us 6000 or 7000 ft. Since we wanted to level and slow at 10000 ft, we did not set in the altitude. After slowing, I asked captain what altitude to set, he responded '6000.' I did not clearly remember, but it sounded right and I set in 6000 ft. After being level at 6000 for several mins, controller called out traffic at 12 O'clock, 5 mi. A moment later, we got a TCASII RA to climb. We followed it (RA) to 6700. Captain asked for phone number to call controller on ground. After calling him, he was told we were only cleared to 7000. Moral 1) set an altitude when you receive it. 2) confirm any clearance you don't absolutely remember clearly and both agree on.
Original NASA ASRS Text
Title: MLG HAD ALTDEV IN THE MSP TCA. THE RPTING ACFT WAS 1000 FT BELOW IT'S CLRNC ALT.
Narrative: WHILE DSNDING TO 10000 CTLR GAVE US 6000 OR 7000 FT. SINCE WE WANTED TO LEVEL AND SLOW AT 10000 FT, WE DID NOT SET IN THE ALT. AFTER SLOWING, I ASKED CAPT WHAT ALT TO SET, HE RESPONDED '6000.' I DID NOT CLRLY REMEMBER, BUT IT SOUNDED RIGHT AND I SET IN 6000 FT. AFTER BEING LEVEL AT 6000 FOR SEVERAL MINS, CTLR CALLED OUT TFC AT 12 O'CLOCK, 5 MI. A MOMENT LATER, WE GOT A TCASII RA TO CLB. WE FOLLOWED IT (RA) TO 6700. CAPT ASKED FOR PHONE NUMBER TO CALL CTLR ON GND. AFTER CALLING HIM, HE WAS TOLD WE WERE ONLY CLRED TO 7000. MORAL 1) SET AN ALT WHEN YOU RECEIVE IT. 2) CONFIRM ANY CLRNC YOU DON'T ABSOLUTELY REMEMBER CLRLY AND BOTH AGREE ON.
