Narrative:

We were given a crossing restr at manes at 11000 ft MSL (pilot discretion). We were at 16000 ft MSL at the time. Center controller didn't ask if we had remembered our crossing restr. Being on duty 2 days in a row more than 12 hours. And 3RD day of a 3 day trip for more than 13 hours. Crew fatigue (tired) played a major role. We made the turn at manes intersection and realized we were still at 16000 ft MSL. We forgot the crossing and were starting down. I asked did we cause any conflicts. There was no answer from center except to contact cvg approach on 123.87, so we did and started down at 2000 FPM. To add to this, it may not be the controller's responsibility to make sure flight crew's make their altitude restrs, but when something like this happens giving the crew some feed back if there was a conflict or not would be a plus. Not to just leave the crew out of the loop.

Title: FLC FORGOT ALT RESTR.

Narrative: WE WERE GIVEN A XING RESTR AT MANES AT 11000 FT MSL (PLT DISCRETION). WE WERE AT 16000 FT MSL AT THE TIME. CTR CTLR DIDN'T ASK IF WE HAD REMEMBERED OUR XING RESTR. BEING ON DUTY 2 DAYS IN A ROW MORE THAN 12 HRS. AND 3RD DAY OF A 3 DAY TRIP FOR MORE THAN 13 HRS. CREW FATIGUE (TIRED) PLAYED A MAJOR ROLE. WE MADE THE TURN AT MANES INTXN AND REALIZED WE WERE STILL AT 16000 FT MSL. WE FORGOT THE XING AND WERE STARTING DOWN. I ASKED DID WE CAUSE ANY CONFLICTS. THERE WAS NO ANSWER FROM CTR EXCEPT TO CONTACT CVG APCH ON 123.87, SO WE DID AND STARTED DOWN AT 2000 FPM. TO ADD TO THIS, IT MAY NOT BE THE CTLR'S RESPONSIBILITY TO MAKE SURE FLC'S MAKE THEIR ALT RESTRS, BUT WHEN SOMETHING LIKE THIS HAPPENS GIVING THE CREW SOME FEED BACK IF THERE WAS A CONFLICT OR NOT WOULD BE A PLUS. NOT TO JUST LEAVE THE CREW OUT OF THE LOOP.
