Narrative:
During preflight; special attention was given to making NOTAM changes to eldee 3 arrival into the FMC. The flight was uneventful until potomac approach told us to cross druzz at 15000 ft and descend via the eldee 3 arrival. After passing druzz at 15000 ft; a descent was begun. Apparently; the FMC had dropped the hard altitude restr at revue during the programming to cross druzz at 15000 ft. Potomac approach told us to recheck our altitude and comply with the eldee 3 restrs. The rest of the STAR was complied with and the flight terminated normally. The eldee 3 arrival has a history of compliance difficulties as evidenced by the lengthy NOTAMS regarding altitude changes to the published STAR arrival. These changes have not been programmed into the FMC database for at least 3 months that I know of. There were plenty of distrs on the descent. WX; IMC conditions; and reprogramming of the FMC to meet controller induced altitude restrs to mention a few. Both pilots missed the fact that the FMC did not reflect the hard crossing altitude at revue. Fatigue may have also been a contributing factor as I had been awake since XA15 CST.
Original NASA ASRS Text
Title: A B757-200 FLT CREW FAILED TO MAKE A CROSS RESTR ON THE ELDEE ARR INTO DCA.
Narrative: DURING PREFLT; SPECIAL ATTENTION WAS GIVEN TO MAKING NOTAM CHANGES TO ELDEE 3 ARR INTO THE FMC. THE FLT WAS UNEVENTFUL UNTIL POTOMAC APCH TOLD US TO CROSS DRUZZ AT 15000 FT AND DSND VIA THE ELDEE 3 ARR. AFTER PASSING DRUZZ AT 15000 FT; A DSCNT WAS BEGUN. APPARENTLY; THE FMC HAD DROPPED THE HARD ALTITUDE RESTR AT REVUE DURING THE PROGRAMMING TO CROSS DRUZZ AT 15000 FT. POTOMAC APCH TOLD US TO RECHECK OUR ALTITUDE AND COMPLY WITH THE ELDEE 3 RESTRS. THE REST OF THE STAR WAS COMPLIED WITH AND THE FLT TERMINATED NORMALLY. THE ELDEE 3 ARR HAS A HISTORY OF COMPLIANCE DIFFICULTIES AS EVIDENCED BY THE LENGTHY NOTAMS REGARDING ALTITUDE CHANGES TO THE PUBLISHED STAR ARR. THESE CHANGES HAVE NOT BEEN PROGRAMMED INTO THE FMC DATABASE FOR AT LEAST 3 MONTHS THAT I KNOW OF. THERE WERE PLENTY OF DISTRS ON THE DSCNT. WX; IMC CONDITIONS; AND REPROGRAMMING OF THE FMC TO MEET CTLR INDUCED ALTITUDE RESTRS TO MENTION A FEW. BOTH PLTS MISSED THE FACT THAT THE FMC DID NOT REFLECT THE HARD CROSSING ALTITUDE AT REVUE. FATIGUE MAY HAVE ALSO BEEN A CONTRIBUTING FACTOR AS I HAD BEEN AWAKE SINCE XA15 CST.
