Narrative:

Operating as scheduled part 121 operator flying between atl to ict. We were being vectored for the ILS to runway 19R. I was PNF and handling the radio xmissions and helping my first officer, who was PF, setting up for approach. Approach controller gave us a final vector to intercept the localizer, and cleared us for the ILS to runway 19R (ict). Final altitude assigned was heard as 2000 ft. I read back 2000 ft and approach controller did not correct me. At this point we were 500 ft above the ground on about a 5 mi final. We had broken out of the clouds at about 2300 ft. We picked up the runway at about 5 mi and continued at 2000 ft until GS intercept. We intercepted the GS and continued uneventfully to a normal landing. At no point did approach controller or tower controller mention altitude.

Title: ALTDEV AND LOW APCH WHEN A B717 FLT CREW DSNDS 1000 FT BELOW THE PUBLISHED XING ALT FOR THE FAF WHEN RESPONDING TO AN ATC CLRNC FOR THE ILS APCH RWY 19 AT ICT, KS.

Narrative: OPERATING AS SCHEDULED PART 121 OPERATOR FLYING BTWN ATL TO ICT. WE WERE BEING VECTORED FOR THE ILS TO RWY 19R. I WAS PNF AND HANDLING THE RADIO XMISSIONS AND HELPING MY FO, WHO WAS PF, SETTING UP FOR APCH. APCH CTLR GAVE US A FINAL VECTOR TO INTERCEPT THE LOC, AND CLRED US FOR THE ILS TO RWY 19R (ICT). FINAL ALT ASSIGNED WAS HEARD AS 2000 FT. I READ BACK 2000 FT AND APCH CTLR DID NOT CORRECT ME. AT THIS POINT WE WERE 500 FT ABOVE THE GND ON ABOUT A 5 MI FINAL. WE HAD BROKEN OUT OF THE CLOUDS AT ABOUT 2300 FT. WE PICKED UP THE RWY AT ABOUT 5 MI AND CONTINUED AT 2000 FT UNTIL GS INTERCEPT. WE INTERCEPTED THE GS AND CONTINUED UNEVENTFULLY TO A NORMAL LNDG. AT NO POINT DID APCH CTLR OR TWR CTLR MENTION ALT.
