Narrative:
The last 2 nights I had been released after work and got to sleep late. The next assignment required an early morning wake-up. I wasn't able to get to sleep easily because of the previous 2 nights late release. I finally fell asleep, leaving me with only 5 hours inbound to cvg. We were given a clearance from 4000 ft to 3000 ft. At 3700 ft we were told to level at 3500 ft. By the time it was set on the alerter, the autoplt was unable to capture. We went through 3500 ft by about 300 ft and climbed back up. Also, on final, the first officer was having problems with the confign and I was distraction trying to fix it. I don't clearly remember being cleared to land. Nobody said anything suggesting we weren't. It just shows how debilitating fatigue is.

Narrative: THE LAST 2 NIGHTS I HAD BEEN RELEASED AFTER WORK AND GOT TO SLEEP LATE. THE NEXT ASSIGNMENT REQUIRED AN EARLY MORNING WAKE-UP. I WASN'T ABLE TO GET TO SLEEP EASILY BECAUSE OF THE PREVIOUS 2 NIGHTS LATE RELEASE. I FINALLY FELL ASLEEP, LEAVING ME WITH ONLY 5 HRS INBOUND TO CVG. WE WERE GIVEN A CLRNC FROM 4000 FT TO 3000 FT. AT 3700 FT WE WERE TOLD TO LEVEL AT 3500 FT. BY THE TIME IT WAS SET ON THE ALERTER, THE AUTOPLT WAS UNABLE TO CAPTURE. WE WENT THROUGH 3500 FT BY ABOUT 300 FT AND CLBED BACK UP. ALSO, ON FINAL, THE FO WAS HAVING PROBS WITH THE CONFIGN AND I WAS DISTR TRYING TO FIX IT. I DON'T CLRLY REMEMBER BEING CLRED TO LAND. NOBODY SAID ANYTHING SUGGESTING WE WEREN'T. IT JUST SHOWS HOW DEBILITATING FATIGUE IS.
