Narrative:

Clearance was issued by ATC as follows: bos to swf via wylyy 2 departure bosox V419 bdl. This clearance was reviewed and programmed into the FMS. The departure procedure was also briefed by the captain and first officer. Unfortunately the FMS was programmed direct from wylyy to bosox since there was no way to program the heading in at wylyy (235 degrees). Even though both crew members had reviewed the departure when wylyy was reached (first officer flying) the autoplt proceeded to turn toward bosox. The captain's attention was diverted at the time due to other duties and I did not note the error. ATC questioned our heading then shortly he cleared us on course. They did not advise us of any conflict. It was at this time that I noticed our error of not flying the 235 degree heading at wylyy. We had turned to about 280 degrees to go direct bosox. In the future, any time a procedure calls for a heading after a fix, I will program in a discontinuity and brief it as such. The discontinuity will remind us to fly the appropriate heading and the autoplt will not turn off the assigned course.

Title: FLC OF A CANADAIR CL65 REGIONAL JET FAILED TO TURN TO THE PUBLISHED SID DEP HDG SHORTLY AFTER TKOF CAUSING ATC INTERVENTION AND A NEW HDG TO ON COURSE. THE PROB AROSE FROM NOT PROGRAMMING THE FMS WITH THE DEP HDG.

Narrative: CLRNC WAS ISSUED BY ATC AS FOLLOWS: BOS TO SWF VIA WYLYY 2 DEP BOSOX V419 BDL. THIS CLRNC WAS REVIEWED AND PROGRAMMED INTO THE FMS. THE DEP PROC WAS ALSO BRIEFED BY THE CAPT AND FO. UNFORTUNATELY THE FMS WAS PROGRAMMED DIRECT FROM WYLYY TO BOSOX SINCE THERE WAS NO WAY TO PROGRAM THE HDG IN AT WYLYY (235 DEGS). EVEN THOUGH BOTH CREW MEMBERS HAD REVIEWED THE DEP WHEN WYLYY WAS REACHED (FO FLYING) THE AUTOPLT PROCEEDED TO TURN TOWARD BOSOX. THE CAPT'S ATTN WAS DIVERTED AT THE TIME DUE TO OTHER DUTIES AND I DID NOT NOTE THE ERROR. ATC QUESTIONED OUR HDG THEN SHORTLY HE CLRED US ON COURSE. THEY DID NOT ADVISE US OF ANY CONFLICT. IT WAS AT THIS TIME THAT I NOTICED OUR ERROR OF NOT FLYING THE 235 DEG HDG AT WYLYY. WE HAD TURNED TO ABOUT 280 DEGS TO GO DIRECT BOSOX. IN THE FUTURE, ANY TIME A PROC CALLS FOR A HDG AFTER A FIX, I WILL PROGRAM IN A DISCONTINUITY AND BRIEF IT AS SUCH. THE DISCONTINUITY WILL REMIND US TO FLY THE APPROPRIATE HDG AND THE AUTOPLT WILL NOT TURN OFF THE ASSIGNED COURSE.
