Narrative:

We had a new hire first officer who was going to ride jump seat with us for observation purposes. He met us on the airplane so I told him to stay with my senior first officer and observe his preflight duties while I went into operations to pick up my dispatch release and his jump seat pass. I picked up my dispatch release out of its cubby hole, looked it over, and signed it. Then I called flight control to request a jump seat pass. Dispatch told me not to use my old release but rather they would send me a new one with the jump seat rider listed on it. Usually we jointly amend the release and pin the jump seat rider's name, so I waited for my new release. One was put in my destination's cubby hole. I picked it up, checked it for my jump seat rider's name, signed, and off I went. I threw my original release away. About 5 mins into the flight, I realized I had signed a release with the wrong flight number and captain, same city and fuel and with my jump seat rider's name. The dispatcher had sent me the wrong release with the right jump seater's name, and correct city, fuel, and route. When I arrived at my destination, I requested an amended release for the return flight home. Factors: 1) fatigue -- 12 leg trip with a scheduled reduced rest remain overnight of 8 hours 20 mins. This was the last round trip. The previous trip was also a two day trip with 12 legs! 2) hurry -- we had a quick turn time because of ATC, WX delays, and short scheduled turn time. This was a factor because I checked my first release 'carefully,' but didn't spend the time to check my second release except for the jump seat rider. Also, dispatch puts 2 or 3 releases for the same city, different times, in the same cubby hole. It's easy to pick up a release for your city, but later on that day, especially when you are hurrying. 3) distrs -- as I waited for my new release, several pilots came up to me and started general conversation. This wasted some valuable time I could have been studying my new dispatch release. I strive to have a consistent pattern of checking my releases and MEL items, however, this time there was an abnormal situation and compounded with the above three factors I made an error. The series of backup checks failed to catch it.

Title: A COMMERCIAL FIXED WING LTT WAS DISPATCHED WITH THE WRONG AND INCORRECT DISPATCH RELEASE.

Narrative: WE HAD A NEW HIRE FO WHO WAS GOING TO RIDE JUMP SEAT WITH US FOR OBSERVATION PURPOSES. HE MET US ON THE AIRPLANE SO I TOLD HIM TO STAY WITH MY SENIOR FO AND OBSERVE HIS PREFLT DUTIES WHILE I WENT INTO OPS TO PICK UP MY DISPATCH RELEASE AND HIS JUMP SEAT PASS. I PICKED UP MY DISPATCH RELEASE OUT OF ITS CUBBY HOLE, LOOKED IT OVER, AND SIGNED IT. THEN I CALLED FLT CTL TO REQUEST A JUMP SEAT PASS. DISPATCH TOLD ME NOT TO USE MY OLD RELEASE BUT RATHER THEY WOULD SEND ME A NEW ONE WITH THE JUMP SEAT RIDER LISTED ON IT. USUALLY WE JOINTLY AMEND THE RELEASE AND PIN THE JUMP SEAT RIDER'S NAME, SO I WAITED FOR MY NEW RELEASE. ONE WAS PUT IN MY DEST'S CUBBY HOLE. I PICKED IT UP, CHKED IT FOR MY JUMP SEAT RIDER'S NAME, SIGNED, AND OFF I WENT. I THREW MY ORIGINAL RELEASE AWAY. ABOUT 5 MINS INTO THE FLT, I REALIZED I HAD SIGNED A RELEASE WITH THE WRONG FLT NUMBER AND CAPT, SAME CITY AND FUEL AND WITH MY JUMP SEAT RIDER'S NAME. THE DISPATCHER HAD SENT ME THE WRONG RELEASE WITH THE RIGHT JUMP SEATER'S NAME, AND CORRECT CITY, FUEL, AND RTE. WHEN I ARRIVED AT MY DEST, I REQUESTED AN AMENDED RELEASE FOR THE RETURN FLT HOME. FACTORS: 1) FATIGUE -- 12 LEG TRIP WITH A SCHEDULED REDUCED REST REMAIN OVERNIGHT OF 8 HRS 20 MINS. THIS WAS THE LAST ROUND TRIP. THE PREVIOUS TRIP WAS ALSO A TWO DAY TRIP WITH 12 LEGS! 2) HURRY -- WE HAD A QUICK TURN TIME BECAUSE OF ATC, WX DELAYS, AND SHORT SCHEDULED TURN TIME. THIS WAS A FACTOR BECAUSE I CHKED MY FIRST RELEASE 'CAREFULLY,' BUT DIDN'T SPEND THE TIME TO CHECK MY SECOND RELEASE EXCEPT FOR THE JUMP SEAT RIDER. ALSO, DISPATCH PUTS 2 OR 3 RELEASES FOR THE SAME CITY, DIFFERENT TIMES, IN THE SAME CUBBY HOLE. IT'S EASY TO PICK UP A RELEASE FOR YOUR CITY, BUT LATER ON THAT DAY, ESPECIALLY WHEN YOU ARE HURRYING. 3) DISTRS -- AS I WAITED FOR MY NEW RELEASE, SEVERAL PLTS CAME UP TO ME AND STARTED GENERAL CONVERSATION. THIS WASTED SOME VALUABLE TIME I COULD HAVE BEEN STUDYING MY NEW DISPATCH RELEASE. I STRIVE TO HAVE A CONSISTENT PATTERN OF CHKING MY RELEASES AND MEL ITEMS, HOWEVER, THIS TIME THERE WAS AN ABNORMAL SIT AND COMPOUNDED WITH THE ABOVE THREE FACTORS I MADE AN ERROR. THE SERIES OF BACKUP CHKS FAILED TO CATCH IT.
