Narrative:

We were cleared to climb to an altitude of 10000 ft. The co-captain responded 'cleared to 17000 ft' and set 17000 ft in altitude preselect. The controller did not respond that our altitude limit was 10000 ft. At 10000 ft our TCASII gave us a traffic alert at which time the co-captain asked the controller what altitude we had been cleared to. He responded 10000 ft. We stopped our climb at 10400 ft. The controller stated his altitude readout showed us above 10000 ft. We responded we were now level at 10000 ft approximately 30 seconds after he notified us of our altitude excursion.

Title: FLC CLBED THROUGH THE ASSIGNED ALT.

Narrative: WE WERE CLRED TO CLB TO AN ALT OF 10000 FT. THE CO-CAPT RESPONDED 'CLRED TO 17000 FT' AND SET 17000 FT IN ALT PRESELECT. THE CTLR DID NOT RESPOND THAT OUR ALT LIMIT WAS 10000 FT. AT 10000 FT OUR TCASII GAVE US A TFC ALERT AT WHICH TIME THE CO-CAPT ASKED THE CTLR WHAT ALT WE HAD BEEN CLRED TO. HE RESPONDED 10000 FT. WE STOPPED OUR CLB AT 10400 FT. THE CTLR STATED HIS ALT READOUT SHOWED US ABOVE 10000 FT. WE RESPONDED WE WERE NOW LEVEL AT 10000 FT APPROX 30 SECONDS AFTER HE NOTIFIED US OF OUR ALT EXCURSION.
