Narrative:

When departing on the westchester nine SID from hpn runway 16 the procedure required a right turn to 320 degree heading at 900 ft. We turned left to 320 degrees at 900 ft. We were already in the turn and almost complete when the controller asked if we had turned left. Although the SID is relatively easy, one of the contributing factors to our error was that ATC changed our initial leveloff altitude from 3000 ft to 2000 ft just before our departure. Normally I review the SID again just before departure but got distracted by setting in the new altitude. I had reviewed the SID when I had received the clearance at the gate from clearance delivery. While reading the SID I noted it was a right turn to 320 degrees, however I had to turn the 'heading set marker' to the left and somehow that 'locked' in my mind that we would turn left to 320 degrees. Additionally most sids we fly have us turning left versus right. Another contributing factor was the multiple tasks required with the departure. A leveloff at 2000 ft comes fast for our aircraft. So between accomplishing checklists, setting the climb thrust, changing radio frequencys, insuring we didn't exceed 200 KTS at 2000 ft, making the required turn at 900 ft, we were in a 'task overload mode' that helped us make the error. 2 actions I believe will avoid this in the future: 1) make sure the SID is reviewed just before takeoff regardless of other tasks at hand, and 2) put the SID on the yoke's chart holder for easy xchk. Supplemental information from acn 373153: discussed with first officer in takeoff briefing, requires right turn at 800 ft MSL to 320 degrees (almost 180 degree turn). Climbing through 1000 ft MSL, PNF mentioned 'left turn to 320 degrees' and PF started turn to left while pulling power back and starting leveloff. Controller was very courteous/professional and steered us in the correct direction. Additional factor is heading bug on CL65 was not visible due to HSI location behind control yoke.

Title: A CL65RJ FLC TURNS THE WRONG WAY FOR THEIR VECTORED SID DEP PROC AFTER TKOF FROM HPN, NY. FO ADVISED THE PIC, PF, OF 'L TURN' AT 1000 FT EVEN THOUGH THE CREW HAD BRIEFED, AT THE RAMP BEFORE DEP, A 'R TURN.'

Narrative: WHEN DEPARTING ON THE WESTCHESTER NINE SID FROM HPN RWY 16 THE PROC REQUIRED A R TURN TO 320 DEG HDG AT 900 FT. WE TURNED L TO 320 DEGS AT 900 FT. WE WERE ALREADY IN THE TURN AND ALMOST COMPLETE WHEN THE CTLR ASKED IF WE HAD TURNED L. ALTHOUGH THE SID IS RELATIVELY EASY, ONE OF THE CONTRIBUTING FACTORS TO OUR ERROR WAS THAT ATC CHANGED OUR INITIAL LEVELOFF ALT FROM 3000 FT TO 2000 FT JUST BEFORE OUR DEP. NORMALLY I REVIEW THE SID AGAIN JUST BEFORE DEP BUT GOT DISTRACTED BY SETTING IN THE NEW ALT. I HAD REVIEWED THE SID WHEN I HAD RECEIVED THE CLRNC AT THE GATE FROM CLRNC DELIVERY. WHILE READING THE SID I NOTED IT WAS A R TURN TO 320 DEGS, HOWEVER I HAD TO TURN THE 'HEADING SET MARKER' TO THE L AND SOMEHOW THAT 'LOCKED' IN MY MIND THAT WE WOULD TURN L TO 320 DEGS. ADDITIONALLY MOST SIDS WE FLY HAVE US TURNING L VERSUS R. ANOTHER CONTRIBUTING FACTOR WAS THE MULTIPLE TASKS REQUIRED WITH THE DEP. A LEVELOFF AT 2000 FT COMES FAST FOR OUR ACFT. SO BTWN ACCOMPLISHING CHKLISTS, SETTING THE CLB THRUST, CHANGING RADIO FREQS, INSURING WE DIDN'T EXCEED 200 KTS AT 2000 FT, MAKING THE REQUIRED TURN AT 900 FT, WE WERE IN A 'TASK OVERLOAD MODE' THAT HELPED US MAKE THE ERROR. 2 ACTIONS I BELIEVE WILL AVOID THIS IN THE FUTURE: 1) MAKE SURE THE SID IS REVIEWED JUST BEFORE TKOF REGARDLESS OF OTHER TASKS AT HAND, AND 2) PUT THE SID ON THE YOKE'S CHART HOLDER FOR EASY XCHK. SUPPLEMENTAL INFO FROM ACN 373153: DISCUSSED WITH FO IN TKOF BRIEFING, REQUIRES R TURN AT 800 FT MSL TO 320 DEGS (ALMOST 180 DEG TURN). CLBING THROUGH 1000 FT MSL, PNF MENTIONED 'L TURN TO 320 DEGS' AND PF STARTED TURN TO L WHILE PULLING PWR BACK AND STARTING LEVELOFF. CTLR WAS VERY COURTEOUS/PROFESSIONAL AND STEERED US IN THE CORRECT DIRECTION. ADDITIONAL FACTOR IS HEADING BUG ON CL65 WAS NOT VISIBLE DUE TO HSI LOCATION BEHIND CTL YOKE.
