AN INCORRECTLY SET ALTIMETER RESULTS IN AN ALT OVERSHOOT DURING DSCNT.

Narrative

I WAS ACTING AS THE PNF IN A 3 MAN CREW CARGO FLT. APPROX 100 MI FROM OUR DEST THE CAPT BEGAN THE DSCNT FROM OUR CRUISE ALT. A FEW MINS INTO OUR DSCNT WE PASSED THROUGH FL180 AND SET OUR ALTIMETERS TO 29.89 ACCORDING TO THE LNDG PERFORMANCE CARD THAT WAS FILLED OUT BY OUR FE AFTER HE LISTENED TO THE DEST ATIS. WE LEVELED OUT AT OUR ASSIGNED ALT OF 10000 FT AT WHICH TIME THE CTLR INFORMED US THAT HE SHOWED US AT 9500 FT. HE TOLD US THE CORRECT ALTIMETER SETTING WAS 29.52 NOT 29.89. WE RESET OUR ALTIMETERS AND IMMEDIATELY ADJUSTED OUR ALT. NO CONFLICT OCCURRED; AND WE CONTINUED TO OUR DEST WITHOUT INCIDENT. THE FE LATER STATED THE ATIS WAS VERY WEAK AND HARD TO UNDERSTAND. IT SEEMS TO ME THAT FATIGUE WAS A PARTIAL FACTOR IN OUR SIT. WE WERE FLYING NIGHT CARGO AND HAD ALL BEEN UP IN EXCESS OF 16 HRS. THE CTR CTLR GAVE US AN ALTIMETER WITH OUR DSCNT CLRNC FOR BUF. OUR DEST WAS ROC; SO I REMEMBER THINKING WE SHOULD USE THE ONE FROM THE ATIS IN ROC. NOT ONE OF US WAS ALERT ENOUGH TO CATCH THIS DISCREPANCY!
