Narrative:

I was flying, captain was performing PNF duties. I was flying the departure by hand in accordance with flight director commands on a vector to intercept a SID. We were in initial stage of climb with a clearance to 10000 ft MSL. Upon checking in with dtw departure control, captain verified passing altitude and noted climbing to 10000 ft. Approximately 1 min later, departure directed a further right turn to approximately 110 degrees to join the SID. He also called out traffic at 10 O'clock, approximately 8000 ft. Captain acknowledged heading, clearance to SID and looking for the traffic. Due to scattered clouds we did not see the traffic. As we passed 8300 ft, departure control called and asked for our altitude. Captain replied passing 8000 and something ft for 10000 ft. Departure said that we were cleared to maintain only 7000 ft. Captain replied, sorry, we have traffic in sight now and understood still cleared to 10000 ft. He also asked if departure wanted us to descend or continue climb. Departure replied to continue to 10000 ft. Neither I nor the captain heard a new altitude clearance of 7000 ft. Traffic was a DC9 approximately 10 O'clock, 3-5 mi, approximately 8000 ft. No conflict or RA ensued. Flight was continued uneventfully. It's a busy time of flight. We were operating in the 'sterile cockpit' mode, received a clearance and traffic report in close succession, complied with the clearance. We acknowledged and looked for traffic. I don't know what else we could have done. I have no explanation for an amended altitude clearance not being received if it were indeed issued.

Title: FLC OF AN AIRBUS A319 OVERSHOT ASSIGNED INTERMEDIATE ALT DURING DEP CLB ACCORDING TO THE DEP CTLR.

Narrative: I WAS FLYING, CAPT WAS PERFORMING PNF DUTIES. I WAS FLYING THE DEP BY HAND IN ACCORDANCE WITH FLT DIRECTOR COMMANDS ON A VECTOR TO INTERCEPT A SID. WE WERE IN INITIAL STAGE OF CLB WITH A CLRNC TO 10000 FT MSL. UPON CHKING IN WITH DTW DEP CTL, CAPT VERIFIED PASSING ALT AND NOTED CLBING TO 10000 FT. APPROX 1 MIN LATER, DEP DIRECTED A FURTHER R TURN TO APPROX 110 DEGS TO JOIN THE SID. HE ALSO CALLED OUT TFC AT 10 O'CLOCK, APPROX 8000 FT. CAPT ACKNOWLEDGED HDG, CLRNC TO SID AND LOOKING FOR THE TFC. DUE TO SCATTERED CLOUDS WE DID NOT SEE THE TFC. AS WE PASSED 8300 FT, DEP CTL CALLED AND ASKED FOR OUR ALT. CAPT REPLIED PASSING 8000 AND SOMETHING FT FOR 10000 FT. DEP SAID THAT WE WERE CLRED TO MAINTAIN ONLY 7000 FT. CAPT REPLIED, SORRY, WE HAVE TFC IN SIGHT NOW AND UNDERSTOOD STILL CLRED TO 10000 FT. HE ALSO ASKED IF DEP WANTED US TO DSND OR CONTINUE CLB. DEP REPLIED TO CONTINUE TO 10000 FT. NEITHER I NOR THE CAPT HEARD A NEW ALT CLRNC OF 7000 FT. TFC WAS A DC9 APPROX 10 O'CLOCK, 3-5 MI, APPROX 8000 FT. NO CONFLICT OR RA ENSUED. FLT WAS CONTINUED UNEVENTFULLY. IT'S A BUSY TIME OF FLT. WE WERE OPERATING IN THE 'STERILE COCKPIT' MODE, RECEIVED A CLRNC AND TFC RPT IN CLOSE SUCCESSION, COMPLIED WITH THE CLRNC. WE ACKNOWLEDGED AND LOOKED FOR TFC. I DON'T KNOW WHAT ELSE WE COULD HAVE DONE. I HAVE NO EXPLANATION FOR AN AMENDED ALT CLRNC NOT BEING RECEIVED IF IT WERE INDEED ISSUED.
