Narrative:
On approach to lszh, we were cleared to descend to 4000 ft, but keep the speed up (300+ KTS). I set the altitude alert to 4000 ft. The captain began to descend on autoplt. As we approached 5000 ft, I gave a call of 1000 ft to go. The captain asked me to find the miles to the airport. As I was looking down at approach plate, aircraft descended to 3000 ft in VFR conditions. We got a terrain alert and a call from ATC of 'too low.' we began a climb back to 4000 ft with no problems. Captain does not remember setting the altitude select to 3000 ft, however, the autoplt speed control knob is next to altitude select control. We were VFR on top at all times. An alert did not cause any operational problems for us.

Title: A CPR JET FLC HAS A NEAR CFIT EXPERIENCE WHEN THE PIC SETS THE ALT ALERT FOR TOO LOW AN ALT ON A HIGH SPD APCH TO LSZH, FO.
Narrative: ON APCH TO LSZH, WE WERE CLRED TO DSND TO 4000 FT, BUT KEEP THE SPD UP (300+ KTS). I SET THE ALT ALERT TO 4000 FT. THE CAPT BEGAN TO DSND ON AUTOPLT. AS WE APCHED 5000 FT, I GAVE A CALL OF 1000 FT TO GO. THE CAPT ASKED ME TO FIND THE MILES TO THE ARPT. AS I WAS LOOKING DOWN AT APCH PLATE, ACFT DSNDED TO 3000 FT IN VFR CONDITIONS. WE GOT A TERRAIN ALERT AND A CALL FROM ATC OF 'TOO LOW.' WE BEGAN A CLB BACK TO 4000 FT WITH NO PROBS. CAPT DOES NOT REMEMBER SETTING THE ALT SELECT TO 3000 FT, HOWEVER, THE AUTOPLT SPD CTL KNOB IS NEXT TO ALT SELECT CTL. WE WERE VFR ON TOP AT ALL TIMES. AN ALERT DID NOT CAUSE ANY OPERATIONAL PROBS FOR US.
