Narrative:

The day started off somewhat normal. It had been snowing on the ground, so our saab 340 needed to be deiced. After the deice process, we departed runway 22L at dtw and proceeded on what we both thought was the course to be flown (the palace 2 departure out of dtw). The palace 2 takes you wbound out of dtw on the 281 radial until 37 DME, then inbound on jxn 094 degree radial. Our hard copy flight plan clearance read as follows: dtw...harwl...lfd...gij...J146...jot...J18...mzv. The clearance that the first officer copied was: mli...P2..rv.. Harwl...jxn...V116...leroy...bij...40...4163, so it was not as filed. When we set up our paperwork, we usually place our hard copy flight plan at eye level above the altitude preselector (folded nicely so we can read the fuel numbers and the actual routing). The actual card with the clearance we received was tucked under the first officer's yoke clip. I knew what the actual clearance was, but somehow I allowed my first officer to fly the clearance that our hard copy flight plan stated. Where I messed up was the fact that we headed for the lfd VOR instead of continuing outbound from the jackson VOR. ZOB quickly caught the mistake and handed us off to the next cleveland controller. I wound up having to call our company dispatcher over the radio in regards to an urgent PIREP in our area and our dispatcher advised us that ZOB had called our dispatch office extremely upset about the incident. I am the captain, I take 100% responsibility for our mistake. I guess the lesson here is make sure you follow your actual clearance, not the computer generated one, and not under one pilot's yoke clip (very hard for other pilot to see).

Title: AN SF340 PIC ALLOWS HIS FO, PF, TO DEVIATE FROM THE AMENDED RTE CLRNC AS HE FOLLOWS THE ORIGINAL FILED FLT PLAN FROM HARWL INTXN NEAR DET, MI.

Narrative: THE DAY STARTED OFF SOMEWHAT NORMAL. IT HAD BEEN SNOWING ON THE GND, SO OUR SAAB 340 NEEDED TO BE DEICED. AFTER THE DEICE PROCESS, WE DEPARTED RWY 22L AT DTW AND PROCEEDED ON WHAT WE BOTH THOUGHT WAS THE COURSE TO BE FLOWN (THE PALACE 2 DEP OUT OF DTW). THE PALACE 2 TAKES YOU WBOUND OUT OF DTW ON THE 281 RADIAL UNTIL 37 DME, THEN INBOUND ON JXN 094 DEG RADIAL. OUR HARD COPY FLT PLAN CLRNC READ AS FOLLOWS: DTW...HARWL...LFD...GIJ...J146...JOT...J18...MZV. THE CLRNC THAT THE FO COPIED WAS: MLI...P2..RV.. HARWL...JXN...V116...LEROY...BIJ...40...4163, SO IT WAS NOT AS FILED. WHEN WE SET UP OUR PAPERWORK, WE USUALLY PLACE OUR HARD COPY FLT PLAN AT EYE LEVEL ABOVE THE ALT PRESELECTOR (FOLDED NICELY SO WE CAN READ THE FUEL NUMBERS AND THE ACTUAL ROUTING). THE ACTUAL CARD WITH THE CLRNC WE RECEIVED WAS TUCKED UNDER THE FO'S YOKE CLIP. I KNEW WHAT THE ACTUAL CLRNC WAS, BUT SOMEHOW I ALLOWED MY FO TO FLY THE CLRNC THAT OUR HARD COPY FLT PLAN STATED. WHERE I MESSED UP WAS THE FACT THAT WE HEADED FOR THE LFD VOR INSTEAD OF CONTINUING OUTBOUND FROM THE JACKSON VOR. ZOB QUICKLY CAUGHT THE MISTAKE AND HANDED US OFF TO THE NEXT CLEVELAND CTLR. I WOUND UP HAVING TO CALL OUR COMPANY DISPATCHER OVER THE RADIO IN REGARDS TO AN URGENT PIREP IN OUR AREA AND OUR DISPATCHER ADVISED US THAT ZOB HAD CALLED OUR DISPATCH OFFICE EXTREMELY UPSET ABOUT THE INCIDENT. I AM THE CAPT, I TAKE 100% RESPONSIBILITY FOR OUR MISTAKE. I GUESS THE LESSON HERE IS MAKE SURE YOU FOLLOW YOUR ACTUAL CLRNC, NOT THE COMPUTER GENERATED ONE, AND NOT UNDER ONE PLT'S YOKE CLIP (VERY HARD FOR OTHER PLT TO SEE).
