A Jazz Aviation de Havilland Dash 8-400, registration C-GGMU performing flight QK-8946 from Toronto,ON to Saint John,NB (Canada), was accelerating for takeoff from Toronto's runway 24R when the left hand engine outboard cowl door separated from the nacelle and struck the left wing leading edge causing damage to the de-icing boots. The crew remained unaware of the occurrence, there were no abnormal engine or other system indications nor were there any engine vibrations. The aircraft continued to destinaton for a safe landing.

The Canadian TSB reported the missing door was noticed only after the aircraft had parked at the terminal. The door was found on runway 24R in Toronto. The operator's maintenance had performed a pre-flight inspection of the engine including engine oil quantity checks in the area of the missing cowl. The operator is investigating.

Transport Canada's Airworthiness reported: "Another aircraft was dispatched to operate the outbound flight. Company Maintenance Personnel and a replacement Door were on the aircraft. Prior to flight, a Service Check and Oil Check were carried out by CYYZ Maintenance, the aircraft overnighted in CYYZ. The Operator inspected the door and found all latches in the locked position with no obvious damage to any of them. The door support strut was missing. CYYZ was advised about the missing strut. They confirmed they had done a full sweep and runway inspection with no sign of the strut. TSB was notified. A Service Difficulty Report (SDR) was submitted. Maintenance issued a Maintenance Safety Alert to all Maintenance Personnel. The Aircraft was returned to service following replacement of the Door and L/H Inboard Leading Edge Assembly. This is the first event of this type for this Operator; however, there have been other similar events with other operators of this aircraft Type. Additionally, Bombardier released Service Bulletin (SB) which includes installing a placard to each cowl door describing (via symbols) the procedures for properly closing the door. All Jazz aircrafts will have this SB completed if not previously done."
