Narrative:
ATC asked us to confirm our assigned altitude, it was FL290. We were climbing out of FL298, ATC cleared us to FL310. We had flown through our assigned altitude. Fuel was out of balance after takeoff. We balanced it in our climb. The PF was using the autoplt. After the fuel appeared to be balanced, he disconnected the autoplt to check trim. The autoplt was re- engaged but not the altitude capture function. I was putting up approach charts and not paying attention as the autoplt was re- engaged or to the altitude we were climbing out of. This is a 24 yr old airplane. To engage the autoplt and all its various functions requires multiple steps. Altitude capture is one of these steps. A step was missed. I was engaged putting up the approach charts and did not back up the PF as the autoplt was engaged, nor did I monitor altitude as I should have.

Title: A CLBING CPR JET OVERSHOT ITS ASSIGNED ALT WHEN THE CREW DOES NOT ADHERE TO DEFINED COCKPIT PROCS.
Narrative: ATC ASKED US TO CONFIRM OUR ASSIGNED ALT, IT WAS FL290. WE WERE CLBING OUT OF FL298, ATC CLRED US TO FL310. WE HAD FLOWN THROUGH OUR ASSIGNED ALT. FUEL WAS OUT OF BAL AFTER TKOF. WE BALANCED IT IN OUR CLB. THE PF WAS USING THE AUTOPLT. AFTER THE FUEL APPEARED TO BE BALANCED, HE DISCONNECTED THE AUTOPLT TO CHK TRIM. THE AUTOPLT WAS RE- ENGAGED BUT NOT THE ALT CAPTURE FUNCTION. I WAS PUTTING UP APCH CHARTS AND NOT PAYING ATTN AS THE AUTOPLT WAS RE- ENGAGED OR TO THE ALT WE WERE CLBING OUT OF. THIS IS A 24 YR OLD AIRPLANE. TO ENGAGE THE AUTOPLT AND ALL ITS VARIOUS FUNCTIONS REQUIRES MULTIPLE STEPS. ALT CAPTURE IS ONE OF THESE STEPS. A STEP WAS MISSED. I WAS ENGAGED PUTTING UP THE APCH CHARTS AND DID NOT BACK UP THE PF AS THE AUTOPLT WAS ENGAGED, NOR DID I MONITOR ALT AS I SHOULD HAVE.
