B757 crew misset their altimeter by 1 inch. This resulted in the aircraft being 1000 ft low.

Narrative:

On STAR approach msp, I set 29.58 in altimeter through FL180. The altimeter should have been 28.58 (lowest recorded in msp history). Received normal ATC call for 28.58. We entered, both pilots, the wrong altimeter setting. We were on the gopher 3 arrival to msp with clearance to cross ollee intersection at 11000 ft. We crossed at 10000 ft due to altimeter setting error. Perhaps an alert call 'low altimeter setting' would have prevented the error. When we switched from ZMP to msp approach, they asked us to check altimeter setting 28.58. We corrected the error, and we were given clearance to 7000 ft. No further error. We inquired with approach control if there was a problem, they told us no.

Original NASA ASRS Text

Title: B757 CREW MISSET THEIR ALTIMETER BY 1 INCH. THIS RESULTED IN THE ACFT BEING 1000 FT LOW.

Narrative: ON STAR APCH MSP, I SET 29.58 IN ALTIMETER THROUGH FL180. THE ALTIMETER SHOULD HAVE BEEN 28.58 (LOWEST RECORDED IN MSP HISTORY). RECEIVED NORMAL ATC CALL FOR 28.58. WE ENTERED, BOTH PLTS, THE WRONG ALTIMETER SETTING. WE WERE ON THE GOPHER 3 ARR TO MSP WITH CLRNC TO CROSS OLLEE INTXN AT 11000 FT. WE CROSSED AT 10000 FT DUE TO ALTIMETER SETTING ERROR. PERHAPS AN ALERT CALL 'LOW ALTIMETER SETTING' WOULD HAVE PREVENTED THE ERROR. WHEN WE SWITCHED FROM ZMP TO MSP APCH, THEY ASKED US TO CHK ALTIMETER SETTING 28.58. WE CORRECTED THE ERROR, AND WE WERE GIVEN CLRNC TO 7000 FT. NO FURTHER ERROR. WE INQUIRED WITH APCH CTL IF THERE WAS A PROB, THEY TOLD US NO.
