Narrative:
We were on radar vectors while descending into the denver area. We had been cleared to descend to 14000 ft MSL from 16000 ft. I was finishing up the approach checklist while the captain was flying. We were in moderate turbulence and in and out of twring cumulus and virga. I had turned around to make sure our passenger, a nurse and patient, were ok for landing. We both called out the '1000 ft to go' callout passing 15000 ft. When I turned back around, the airplane was at 13500 ft. The captain had taken his attention away from flying and was looking at the GPS. He and I realized the discrepancy at the same time and climbed back up to 14000 ft. We have both reiterated the need for attention during climbs and dscnts, and the necessity to make sure someone is always flying the airplane.

Title: DURING DSCNT INTO DEN AREA, ENCOUNTERING TURB, LJ25 FLT CREW BECOME DISTR AND OVERSHOOT ASSIGNED ALT.
Narrative: WE WERE ON RADAR VECTORS WHILE DSNDING INTO THE DENVER AREA. WE HAD BEEN CLRED TO DSND TO 14000 FT MSL FROM 16000 FT. I WAS FINISHING UP THE APCH CHKLIST WHILE THE CAPT WAS FLYING. WE WERE IN MODERATE TURB AND IN AND OUT OF TWRING CUMULUS AND VIRGA. I HAD TURNED AROUND TO MAKE SURE OUR PAX, A NURSE AND PATIENT, WERE OK FOR LNDG. WE BOTH CALLED OUT THE '1000 FT TO GO' CALLOUT PASSING 15000 FT. WHEN I TURNED BACK AROUND, THE AIRPLANE WAS AT 13500 FT. THE CAPT HAD TAKEN HIS ATTN AWAY FROM FLYING AND WAS LOOKING AT THE GPS. HE AND I REALIZED THE DISCREPANCY AT THE SAME TIME AND CLBED BACK UP TO 14000 FT. WE HAVE BOTH REITERATED THE NEED FOR ATTN DURING CLBS AND DSCNTS, AND THE NECESSITY TO MAKE SURE SOMEONE IS ALWAYS FLYING THE AIRPLANE.
