Narrative:

Clearance to maintain runway heading vectors to 092 of mfd maintain 4000'. After takeoff we were cleared to turn left to 260 degrees, intercept 092 of mfd on course and climb and maintain 10000' which I read back. At 9000' on a 260 degree heading and 250 KTS departure said, 'you were only cleared to 8000', turn left to 230 degrees, and descend immediately to 8000',' which we did, and I replied. I read back 10000'. Departure control discovered the problem. We turned left and descended to 8000'. There was no severe evasive action. Communication breakdown on the readback.

Title: ACR MLG OVERSHOT ALT ON CLIMB.

Narrative: CLRNC TO MAINTAIN RWY HDG VECTORS TO 092 OF MFD MAINTAIN 4000'. AFTER TKOF WE WERE CLRED TO TURN LEFT TO 260 DEGS, INTERCEPT 092 OF MFD ON COURSE AND CLB AND MAINTAIN 10000' WHICH I READ BACK. AT 9000' ON A 260 DEG HDG AND 250 KTS DEP SAID, 'YOU WERE ONLY CLRED TO 8000', TURN LEFT TO 230 DEGS, AND DSND IMMEDIATELY TO 8000',' WHICH WE DID, AND I REPLIED. I READ BACK 10000'. DEP CTL DISCOVERED THE PROB. WE TURNED LEFT AND DSNDED TO 8000'. THERE WAS NO SEVERE EVASIVE ACTION. COM BREAKDOWN ON THE READBACK.
