Incident at CALGARY INTL AB (CYYC)

Summary

2015-10-22: A SkyWest Airlines Bombardier CL-600 2B19 (SKW5514) from Calgary, AB (CYYC) to Denver, CO (KDEN), departing Runway 17L, was not observed in the standard instrument departure (SID) turn heading 155. The Tower asked SKW5514 if they were in the turn to heading 155; SKW5514 acknowledged. Approximately 30 seconds later, SKW5514 was observed on radar tracking slightly towards the departure path Runway 17R at the same altitude as a WestJet Boeing 737 800 (WJA179) from Calgary, AB (CYYC) to Comox, BC (CYQQ) departing Runway 17R. Spacing decreased to 1.1 miles before departure made contact with SKW5514 and turned them southeast.
2015-11-12: UPDATE: TSB#A15W0159: The SkyWest Airlines Inc. Bombardier CL-600-2B19 (CRJ200), N479CA, was operating as flight SKW5514 from Calgary, AB (CYYC) to Denver, CO (KDEN). During the departure from Runway 17L, safety was not assured as SKW5514's flight path converged towards WestJet flight WJA179, departing on Runway 17R. A faulty heading indicator led the pilot flying to turn right after takeoff, as he was following the SID procedure. The crew then received an ?EFIS Comp Mon? message and the pilot not flying asked to stop the turn. The comparator monitor (EFIS Comp Mon) is associated with the Attitude Heading and Reference System (AHRS) which continuously looks at each heading indicator for calibration and comparison between indicators. The heading indicator of the pilot not flying had the correct information, so the indicator of the pilot flying was slaved to his. SKW5514 had visual contact with the WestJet aircraft throughout the departure.
