Narrative:
We were very tired after having flown all night and a minimum stay at the field hotel. Bos was in the middle of a heavy snow storm, so our predep workload was very high. Calculation of optional v-spds for takeoff, possible clutter problem, deicing and hold-over calculations, taxi at night non snow covered txwys with little surface markings, cold WX operations, engine run-ups, clean wing check before takeoff. The SID was logan from runway 4R. We both read the departure as runway heading or as assigned. The problem was, this was for non-turbojet aircraft. We should have turned to heading of 090 degrees at 4 DME. ATC asked us about the turn about 8 DME. He was very nice about it, and after our apologies, all seemed ok. In conclusion, no matter how busy we were and how high our workload, we both should have made more time for a more thorough check and reading of the SID.

Title: A90 ALERTS B767 FLT CREW OF BOS SID TRACK DEV. UPON REVIEW, FLT CREW RECOGNIZES THEY WERE FLYING THE TURBOPROP ROUTING.
Narrative: WE WERE VERY TIRED AFTER HAVING FLOWN ALL NIGHT AND A MINIMUM STAY AT THE FIELD HOTEL. BOS WAS IN THE MIDDLE OF A HVY SNOW STORM, SO OUR PREDEP WORKLOAD WAS VERY HIGH. CALCULATION OF OPTIONAL V-SPDS FOR TKOF, POSSIBLE CLUTTER PROB, DEICING AND HOLD-OVER CALCULATIONS, TAXI AT NIGHT NON SNOW COVERED TXWYS WITH LITTLE SURFACE MARKINGS, COLD WX OPS, ENG RUN-UPS, CLEAN WING CHK BEFORE TKOF. THE SID WAS LOGAN FROM RWY 4R. WE BOTH READ THE DEP AS RWY HDG OR AS ASSIGNED. THE PROB WAS, THIS WAS FOR NON-TURBOJET ACFT. WE SHOULD HAVE TURNED TO HDG OF 090 DEGS AT 4 DME. ATC ASKED US ABOUT THE TURN ABOUT 8 DME. HE WAS VERY NICE ABOUT IT, AND AFTER OUR APOLOGIES, ALL SEEMED OK. IN CONCLUSION, NO MATTER HOW BUSY WE WERE AND HOW HIGH OUR WORKLOAD, WE BOTH SHOULD HAVE MADE MORE TIME FOR A MORE THOROUGH CHK AND READING OF THE SID.
