Narrative:

I was hand-flying the aircraft up to FL230. I thought we were cleared up to our cruise flight level of FL330, but actually were told to expect FL330. Shortly upon our checking in with the center frequency, I climbed up to 23300' when the altitude alert sounded, at which time I returned to FL230. The lack of crew coordination on my part with my first officer would have avoided this deviation. If I would have questioned the clearance with him, I would have understood the altitude restriction.

Title: FLT CREW OF MLG IN CLIMB OVERSHOT ASSIGNED ALT.

Narrative: I WAS HAND-FLYING THE ACFT UP TO FL230. I THOUGHT WE WERE CLRED UP TO OUR CRUISE FLT LEVEL OF FL330, BUT ACTUALLY WERE TOLD TO EXPECT FL330. SHORTLY UPON OUR CHKING IN WITH THE CENTER FREQ, I CLBED UP TO 23300' WHEN THE ALT ALERT SOUNDED, AT WHICH TIME I RETURNED TO FL230. THE LACK OF CREW COORD ON MY PART WITH MY F/O WOULD HAVE AVOIDED THIS DEVIATION. IF I WOULD HAVE QUESTIONED THE CLRNC WITH HIM, I WOULD HAVE UNDERSTOOD THE ALT RESTRICTION.
