Narrative:
Ict approach control instructed us to descend to 4000 ft. First officer was flying the aircraft with autoplt engaged. Captain made the '5000 ft for 4000 ft' call and went heads-up to try to find the airport (ict) visually. First officer forgot to engage the autoplt altitude capture feature, and aircraft descended to approximately 3700 ft MSL before we realized what was happening, when the altitude warning horn went off. Aircraft went to approximately 3600 ft MSL during 'recovery,' as the captain disconnected the autoplt and returned the aircraft to 4000 ft. First officer had also been heads-up during the transition through 4000 ft instead of monitoring the autoplt.

Title: A B727 FLT CREW FAILED TO SET ALT CAPTURE ON THE AUTOPLT, RESULTING IN AN ALTDEV.
Narrative: ICT APCH CTL INSTRUCTED US TO DSND TO 4000 FT. FO WAS FLYING THE ACFT WITH AUTOPLT ENGAGED. CAPT MADE THE '5000 FT FOR 4000 FT' CALL AND WENT HEADS-UP TO TRY TO FIND THE ARPT (ICT) VISUALLY. FO FORGOT TO ENGAGE THE AUTOPLT ALT CAPTURE FEATURE, AND ACFT DSNDED TO APPROX 3700 FT MSL BEFORE WE REALIZED WHAT WAS HAPPENING, WHEN THE ALT WARNING HORN WENT OFF. ACFT WENT TO APPROX 3600 FT MSL DURING 'RECOVERY,' AS THE CAPT DISCONNECTED THE AUTOPLT AND RETURNED THE ACFT TO 4000 FT. FO HAD ALSO BEEN HEADS-UP DURING THE TRANSITION THROUGH 4000 FT INSTEAD OF MONITORING THE AUTOPLT.
