Narrative:

I was operating as PNF into atlanta. During arrival; we received a crossing restr 75 NM north of rmg VOR at FL280 to cross 40 NM north of rmg at FL240. The crossing restr was promptly loading into the FMS and altitude set in the altitude window. I then proceeded with PNF duties of preparing for approach into atlanta by obtaining local WX and setting landing data. Shortly thereafter; we were queried by ATC about meeting our restr. It was only then that I noticed we had overflown our descent restr and would not be able to comply. ATC then issued an amended descent to FL270. Later; in discussion with the captain; I found out that he was under the impression during that time that it was my leg. As a result; he subsequently was expecting me to comply with the issued crossing restr. My failure to ensure that he began the descent at the appropriate time was also a contributing factor. In order to prevent the recurrence of this event; I would maintain extra vigilance when issued crossing restrs and possibly delay accomplishing certain PNF duties until a descent to meet a restr has been initiated. Furthermore; proper workload management is important in maintaining situational awareness during busy phases of flight.

Original NASA ASRS Text

Title: CRJ200 FLT CREW MISSED THE CROSSING RESTRICTION ISSUED ON DESCENT.

Narrative: I WAS OPERATING AS PNF INTO ATLANTA. DURING ARR; WE RECEIVED A XING RESTR 75 NM N OF RMG VOR AT FL280 TO CROSS 40 NM N OF RMG AT FL240. THE XING RESTR WAS PROMPTLY LOADING INTO THE FMS AND ALT SET IN THE ALT WINDOW. I THEN PROCEEDED WITH PNF DUTIES OF PREPARING FOR APCH INTO ATLANTA BY OBTAINING LCL WX AND SETTING LNDG DATA. SHORTLY THEREAFTER; WE WERE QUERIED BY ATC ABOUT MEETING OUR RESTR. IT WAS ONLY THEN THAT I NOTICED WE HAD OVERFLOWN OUR DSCNT RESTR AND WOULD NOT BE ABLE TO COMPLY. ATC THEN ISSUED AN AMENDED DSCNT TO FL270. LATER; IN DISCUSSION WITH THE CAPT; I FOUND OUT THAT HE WAS UNDER THE IMPRESSION DURING THAT TIME THAT IT WAS MY LEG. AS A RESULT; HE SUBSEQUENTLY WAS EXPECTING ME TO COMPLY WITH THE ISSUED XING RESTR. MY FAILURE TO ENSURE THAT HE BEGAN THE DSCNT AT THE APPROPRIATE TIME WAS ALSO A CONTRIBUTING FACTOR. IN ORDER TO PREVENT THE RECURRENCE OF THIS EVENT; I WOULD MAINTAIN EXTRA VIGILANCE WHEN ISSUED XING RESTRS AND POSSIBLY DELAY ACCOMPLISHING CERTAIN PNF DUTIES UNTIL A DSCNT TO MEET A RESTR HAS BEEN INITIATED. FURTHERMORE; PROPER WORKLOAD MGMNT IS IMPORTANT IN MAINTAINING SITUATIONAL AWARENESS DURING BUSY PHASES OF FLT.
