A cpr first officer on a CL601 was receiving ATIS at sdf. While off frequency, the captain received an altitude change, but did not change the altitude alerter, causing them to overshoot.

Narrative:
While approaching sdf, I (sic) went off frequency to obtain the ATIS at sdf. While I was doing this, the PIC received instructions to descend from 7000 ft to 6000 ft and a heading change. Apparently, the PIC became distraction by subsequent radio information and my airport briefing (when I returned on frequency) and neglected to reset the altitude pre-select from 7000 ft to 6000 ft. We subsequently descended to 5000 ft before realizing what had happened. The controller also informed us of this fact. We immediately returned to 6000 ft without incident. ATIS information can sometimes be time consuming to gather and is only obtainable during the highest workload periods of a flight. This was definitely the case here.
Original NASA ASRS Text
Title: A CPR FO ON A CL601 WAS RECEIVING ATIS AT SDF. WHILE OFF FREQ, THE CAPT RECEIVED AN ALT CHANGE, BUT DID NOT CHANGE THE ALT ALERTER, CAUSING THEM TO OVERSHOOT.
Narrative: WHILE APCHING SDF, I (SIC) WENT OFF FREQ TO OBTAIN THE ATIS AT SDF. WHILE I WAS DOING THIS, THE PIC RECEIVED INSTRUCTIONS TO DSND FROM 7000 FT TO 6000 FT AND A HDG CHANGE. APPARENTLY, THE PIC BECAME DISTR BY SUBSEQUENT RADIO INFO AND MY ARPT BRIEFING (WHEN I RETURNED ON FREQ) AND NEGLECTED TO RESET THE ALT PRE-SELECT FROM 7000 FT TO 6000 FT. WE SUBSEQUENTLY DSNDED TO 5000 FT BEFORE REALIZING WHAT HAD HAPPENED. THE CTLR ALSO INFORMED US OF THIS FACT. WE IMMEDIATELY RETURNED TO 6000 FT WITHOUT INCIDENT. ATIS INFO CAN SOMETIMES BE TIME CONSUMING TO GATHER AND IS ONLY OBTAINABLE DURING THE HIGHEST WORKLOAD PERIODS OF A FLT. THIS WAS DEFINITELY THE CASE HERE.
