Narrative:
The event occurred during descent into msp airport. On the descent from cruise altitude, the wrong altimeter setting was entered passing through FL180. The error resulted in the aircraft being 1000 ft lower than indicated. This error was not picked up by ATC until we were told to level off at 4000 ft MSL. Msp approach questioned us as we passed through 5000 ft indicated (4000 ft actual altitude) and asked us to check our altimeter setting and restated the current altimeter. He then immediately cleared us to 3000 ft as we corrected the altimeter setting.

Title: CL65 FLC MISTAKENLY SET THE WRONG ALTIMETER SETTING DSNDING THROUGH FL180 CAUSING THEM TO BE 1000 FT LOWER THAN ASSIGNED. APCH CTLR NOTICED THE ACFT DSNDING THROUGH THE ASSIGNED ALT AND ALERTED THEM WITH THE CORRECT ALTIMETER SETTING.
Narrative: THE EVENT OCCURRED DURING DSCNT INTO MSP ARPT. ON THE DSCNT FROM CRUISE ALT, THE WRONG ALTIMETER SETTING WAS ENTERED PASSING THROUGH FL180. THE ERROR RESULTED IN THE ACFT BEING 1000 FT LOWER THAN INDICATED. THIS ERROR WAS NOT PICKED UP BY ATC UNTIL WE WERE TOLD TO LEVEL OFF AT 4000 FT MSL. MSP APCH QUESTIONED US AS WE PASSED THROUGH 5000 FT INDICATED (4000 FT ACTUAL ALT) AND ASKED US TO CHK OUR ALTIMETER SETTING AND RESTATED THE CURRENT ALTIMETER. HE THEN IMMEDIATELY CLRED US TO 3000 FT AS WE CORRECTED THE ALTIMETER SETTING.
