Narrative:

At AB20 am apr/thu/97, I, the pilot of a twin beech hauling night freight outclbed my altitude by 1000 ft. I was assigned and filed for 7000 ft and climbed to 8000 ft with approach. I was then handed off to center. At this time I was alerted of my condition as I also noticed. I fly this run 4 nights a week and fly down at 8000 ft and typically return at 7000 ft. I was almost empty at the time and had a much higher climb rate coming out of dfw than usual. Although there is no excuse, they say that AB00 am to AD00 am is a bad time for fatigue related incidents. Communications on company frequency may have also cluttered the cockpit with distraction.

I WAS THEN HANDED OFF TO CTR. AT THIS TIME I WAS ALERTED OF MY CONDITION AS I ALSO NOTICED. I FLY THIS RUN 4 NIGHTS A WK AND FLY DOWN AT 8000 FT AND TYPICALLY RETURN AT 7000 FT. I WAS ALMOST EMPTY AT THE TIME AND HAD A MUCH HIGHER CLB RATE COMING OUT OF DFW THAN USUAL. ALTHOUGH THERE IS NO EXCUSE, THEY SAY THAT AB00 AM TO AD00 AM IS A BAD TIME FOR FATIGUE RELATED INCIDENTS.
