While climbing through FL310 on autopilot the aircraft pitched up sharply by 20 degrees, the IAS increased by about 40 knots and the aircraft rolled 45 degrees to the right. The autopilot applied full left aileron, the aircraft rolled 30 degrees to the left, the autopilot applied full right ailerons, the VSI indicated 6000fpm climb. The IAS reduced by about 25 knots again and the aircraft levelled off at FL350, significant buffeting continued however. The aircraft continued to Edmonton for a safe landing. The Canadian TSB reported: "There were no injuries; however, 14 passengers became ill as a result of the turbulence." The crew chose to leave the autopilot engaged throughout the event. The operator reported the autopilot performed adequately, no aircraft limitations were exceeded.
