Narrative:

I was working the final day of a scheduled trip. It was a flight delayed due to a late aircraft arrival. My first officer and I had previously discussed his flight time legality issues that arose during the new bid schedule integration period. He indicated that he had several contacts with crew tracking regarding the issues. Also, he indicated that after the final contact, everything was resolved, he had checked his times, and all was well for him to finish our trip. When the aircraft called in range I collected my crew. The station operations agents requested we attempt to depart earlier than the scheduled delayed departure time for gate availability and for the approaching thunderstorms. Dispatch approved. Upon our arrival, dispatch informed me that I had the wrong first officer on the flight and that the correct first officer had arrived at the gate after we departed. I found I had overlooked a name change on my release. This was the first time I knew of the intended crew change. Also at this time, I was informed that my first officer had made incorrect calculations in the morning and had just flown over 30 hours in 7 days on this leg. After talking to the parties involved, I found that I had the last chance to catch errors in communication and calculation as I am supposed to. Apparently, there was not a clear indication to my first officer that crew tracking knew he needed to go off duty. His error along with the fact that no replacement crew was present set the stage for my error. I was obviously concerned with WX, operations concerns, and 16 hour duty day issues coming into play soon. Making as efficient a turn as possible led to my oversight. I feel our crew shortages have also led to many crew changes during trips causing many communications to be necessary. Finally, I must add that the flight (and return) went smoothly.

Title: AN ACR OPERATES IN NON COMPLIANCE WITH CREW DUTY FLT TIME REGS DUE TO A BREAKDOWN IN COM AND DUTY TIME CALCULATIONS.

Narrative: I WAS WORKING THE FINAL DAY OF A SCHEDULED TRIP. IT WAS A FLT DELAYED DUE TO A LATE ACFT ARR. MY FO AND I HAD PREVIOUSLY DISCUSSED HIS FLT TIME LEGALITY ISSUES THAT AROSE DURING THE NEW BID SCHEDULE INTEGRATION PERIOD. HE INDICATED THAT HE HAD SEVERAL CONTACTS WITH CREW TRACKING REGARDING THE ISSUES. ALSO, HE INDICATED THAT AFTER THE FINAL CONTACT, EVERYTHING WAS RESOLVED, HE HAD CHKED HIS TIMES, AND ALL WAS WELL FOR HIM TO FINISH OUR TRIP. WHEN THE ACFT CALLED IN RANGE I COLLECTED MY CREW. THE STATION OPS AGENTS REQUESTED WE ATTEMPT TO DEPART EARLIER THAN THE SCHEDULED DELAYED DEP TIME FOR GATE AVAILABILITY AND FOR THE APCHING TSTMS. DISPATCH APPROVED. UPON OUR ARR, DISPATCH INFORMED ME THAT I HAD THE WRONG FO ON THE FLT AND THAT THE CORRECT FO HAD ARRIVED AT THE GATE AFTER WE DEPARTED. I FOUND I HAD OVERLOOKED A NAME CHANGE ON MY RELEASE. THIS WAS THE FIRST TIME I KNEW OF THE INTENDED CREW CHANGE. ALSO AT THIS TIME, I WAS INFORMED THAT MY FO HAD MADE INCORRECT CALCULATIONS IN THE MORNING AND HAD JUST FLOWN OVER 30 HRS IN 7 DAYS ON THIS LEG. AFTER TALKING TO THE PARTIES INVOLVED, I FOUND THAT I HAD THE LAST CHANCE TO CATCH ERRORS IN COM AND CALCULATION AS I AM SUPPOSED TO. APPARENTLY, THERE WAS NOT A CLR INDICATION TO MY FO THAT CREW TRACKING KNEW HE NEEDED TO GO OFF DUTY. HIS ERROR ALONG WITH THE FACT THAT NO REPLACEMENT CREW WAS PRESENT SET THE STAGE FOR MY ERROR. I WAS OBVIOUSLY CONCERNED WITH WX, OPS CONCERNS, AND 16 HR DUTY DAY ISSUES COMING INTO PLAY SOON. MAKING AS EFFICIENT A TURN AS POSSIBLE LED TO MY OVERSIGHT. I FEEL OUR CREW SHORTAGES HAVE ALSO LED TO MANY CREW CHANGES DURING TRIPS CAUSING MANY COMS TO BE NECESSARY. FINALLY, I MUST ADD THAT THE FLT (AND RETURN) WENT SMOOTHLY.
