Narrative:
Flight was cleared to 8000 ft. During climb we noticed unusually high itt on left engine. Both crew members became preoccupied with the itt and failed to notice aircraft climbing through assigned altitude. I believe fatigue from 12 legs and 15 hours of flying in previous 2 days combined with very early start times contributed to this event. (2 previous days with back-to-back 14 hour duty periods.)

Title: ALT OVERSHOOT. ATTN DIVERTED DUE TO FLC DISTR ACFT EQUIP PROB AND FATIGUE.
Narrative: FLT WAS CLRED TO 8000 FT. DURING CLB WE NOTICED UNUSUALLY HIGH ITT ON L ENG. BOTH CREW MEMBERS BECAME PREOCCUPIED WITH THE ITT AND FAILED TO NOTICE ACFT CLBING THROUGH ASSIGNED ALT. I BELIEVE FATIGUE FROM 12 LEGS AND 15 HRS OF FLYING IN PREVIOUS 2 DAYS COMBINED WITH VERY EARLY START TIMES CONTRIBUTED TO THIS EVENT. (2 PREVIOUS DAYS WITH BACK-TO-BACK 14 HR DUTY PERIODS.)
