A CAPTAIN RECEIVING CRJ-900 INITIAL OPERATING EXPERIENCE MIS-PROGRAMMED AN ATC CROSSING RESTRICTION IN THE FMC. THE CHECK AIRMAN FLYING IN THE RIGHT SEAT MISSED THE ERROR SO THE AIRCRAFT WAS HIGH AT THE INTERSECTION. FATIGUE WAS A FACTOR.

Narrative

CTR GAVE US A XING RESTR. WE WERE AT FL190; CLRED TO CROSS 15 MI OUR SIDE OF ABC INTXN AT 10000 FT. LINE CHK AIRMAN WAS PF IN THE R SEAT. CAPT WAS TRYING TO GET CAUGHT UP ON DUTIES IN PREPARATION FOR ARR AT ZZZ. CAPT ENTERED 10000 FT INTO FMS; BUT AT ABC INTXN; NOT 15 MI OUT. LINE CHK AIRMAN DID NOT CATCH MISTAKE. ATC ASKED CREW IF ABLE TO MAKE XING RESTR; AT WHICH POINT A SOMEWHAT RAPID DSCNT WAS COMMENCED. ACFT WAS PASSING THROUGH ABOUT 12000 FT AT THE 15 MI POINT; AND LEVELED OFF APPROX 12 MI FROM ABC INTXN. ATC WAS ASKED IF THERE WERE ANY CONFLICTS RESULTING FROM DEV; AND TOLD US THERE WERE NOT. SEVERAL FACTORS. BOTH PLTS WERE FATIGUED FROM A ROUGH WK OF OPERATIONAL EXPERIENCE. IN ADDITION; THE CAPT WAS FIGHTING A COLD. I HAD A GUT FEELING THAT BOTH PLTS' FATIGUE COMBINED WITH THE STRESS OF OPERATIONAL EXPERIENCE AND THE CAPT'S ILLNESS WOULD RESULT IN A ROUGH DAY. AS A RESULT; I WAS EXTRA VIGILANT THROUGHOUT THE DAY; BUT MISSED THE ERRONEOUS PROGRAMMING OF THE FMS. I'LL BE FOLLOWING MY GUT INSTINCT AND EITHER CALLING IN SICK MYSELF OR INSISTING THAT THE OTHER PLT DO SO IF THERE'S ANY DOUBT THAT THE FLT CAN BE COMPLETED WITHOUT INCIDENT.
