Altitude deviation. Reporter pilot's company called to fly a flight in the middle of the pilot's sleep schedule and consequently the reporter had only 3 hours sleep. Fatigue a major factor in the reporter climbing through the assigned altitude which caused a loss of separation.

Narrative:
Every night for the past 5 months I have done the same route and have become used to the same clrncs. On mar/wed/96 my company suddenly advised me to show up to work 5 1/2 hours early. This did not fit with my schedule and I lost sleep. Literally, I had 3 hours of sleep. When orl gave me a clearance, 'cleared as filed, climb and maintain 3000 ft' I believe I repeated it correctly. However, I continued climb through 3000 ft to 5000 ft creating a non critical traffic conflict. I offered to descend to 3000 ft (not knowing that is where I was supposed to be). I had the traffic in sight at all times but if I were IMC, would the controller have advised me of my error? I hope so. Fatigue and complacency are the direct problems. They go hand-in-hand to a certain point. The other factor that should be investigated is the fact that my company forced me to fly 5 1/2 hours earlier than I was prepared, leaving me physically strained. If I would've refused there are enough pilots to cover me when they fire me. Too many pilots is the main cause for lousy treatment of pilots.

Title: ALTDEV. RPTR PLT'S COMPANY CALLED TO FLY A FLT IN THE MIDDLE OF THE PLT'S SLEEP SCHEDULE AND CONSEQUENTLY THE RPTR HAD ONLY 3 HRS SLEEP. FATIGUE A MAJOR FACTOR IN THE RPTR CLBING THROUGH THE ASSIGNED ALT WHICH CAUSED A LOSS OF SEPARATION.
Narrative: EVERY NIGHT FOR THE PAST 5 MONTHS I HAVE DONE THE SAME RTE AND HAVE BECOME USED TO THE SAME CLRNCS. ON MAR/WED/96 MY COMPANY SUDDENLY ADVISED ME TO SHOW UP TO WORK 5 1/2 HRS EARLY. THIS DID NOT FIT WITH MY SCHEDULE AND I LOST SLEEP. LITERALLY, I HAD 3 HRS OF SLEEP. WHEN ORL GAVE ME A CLRNC, 'CLRED AS FILED, CLB AND MAINTAIN 3000 FT' I BELIEVE I REPEATED IT CORRECTLY. HOWEVER, I CONTINUED CLB THROUGH 3000 FT TO 5000 FT CREATING A NON CRITICAL TFC CONFLICT. I OFFERED TO DSND TO 3000 FT (NOT KNOWING THAT IS WHERE I WAS SUPPOSED TO BE). I HAD THE TFC IN SIGHT AT ALL TIMES BUT IF I WERE IMC, WOULD THE CTLR HAVE ADVISED ME OF MY ERROR? I HOPE SO. FATIGUE AND COMPLACENCY ARE THE DIRECT PROBS. THEY GO HAND-IN-HAND TO A CERTAIN POINT. THE OTHER FACTOR THAT SHOULD BE INVESTIGATED IS THE FACT THAT MY COMPANY FORCED ME TO FLY 5 1/2 HRS EARLIER THAN I WAS PREPARED, LEAVING ME PHYSICALLY STRAINED. IF I WOULD'VE REFUSED THERE ARE ENOUGH PLTS TO COVER ME WHEN THEY FIRE ME. TOO MANY PLTS IS THE MAIN CAUSE FOR LOUSY TREATMENT OF PLTS.
