Narrative:

Captain was flying the aircraft on 4TH leg after early get up (XA00). We were at 300 KIAS at 11000 ft and were given a descent to 9000 ft. While descending and slowing to 250 KIAS, we were given a left turn to 270 degrees (about 40 degrees). We were then told to slow to 210 KIAS. About this time, we heard the altitude alert. No one had noticed that we had gone through our assigned altitude. We immediately climbed back to our assigned altitude of 9000 ft. We were aware of no traffic conflicts, and approach control gave no indication that they noticed the deviation. More attention to basics, such as aircraft control, would have prevented this one.

Title: B727 ALTDEV DURING HIGH WORKLOAD TIME APCH TO ORD.

Narrative: CAPT WAS FLYING THE ACFT ON 4TH LEG AFTER EARLY GET UP (XA00). WE WERE AT 300 KIAS AT 11000 FT AND WERE GIVEN A DSCNT TO 9000 FT. WHILE DSNDING AND SLOWING TO 250 KIAS, WE WERE GIVEN A L TURN TO 270 DEGS (ABOUT 40 DEGS). WE WERE THEN TOLD TO SLOW TO 210 KIAS. ABOUT THIS TIME, WE HEARD THE ALT ALERT. NO ONE HAD NOTICED THAT WE HAD GONE THROUGH OUR ASSIGNED ALT. WE IMMEDIATELY CLBED BACK TO OUR ASSIGNED ALT OF 9000 FT. WE WERE AWARE OF NO TFC CONFLICTS, AND APCH CTL GAVE NO INDICATION THAT THEY NOTICED THE DEV. MORE ATTN TO BASICS, SUCH AS ACFT CTL, WOULD HAVE PREVENTED THIS ONE.
