Occurrence
On 22 March 2024, an incident occurred at Toronto/Lester B. Pearson International Airport, Ontario, involving two Boeing 787 aircraft. A Boeing 787-10 operated by KLM Royal Dutch Airlines was holding short at the threshold of Runway 06L. A Boeing 787-9 operated by LOT Polish Airlines was landing on the same runway.
Sequence of Events
After the LOT Polish Airlines aircraft landed, air traffic control (ATC) instructed the departing KLM aircraft to line up on Runway 06L and be ready for an immediate takeoff. The LOT aircraft appeared to be exiting onto Taxiway C5, located near the end of the runway. Based on this observation, ATC cleared the KLM aircraft for takeoff.
Shortly after the clearance, the LOT aircraft exited the runway via Taxiway C7 instead of Taxiway C5, which is adjacent to C5. In response, ATC ordered the KLM flight to abort its takeoff. The KLM aircraft had reached a speed of approximately 100 knots before slowing down and coming to a stop about 5400 feet from the LOT aircraft.
Investigation
The Transportation Safety Board of Canada (TSB) is investigating the occurrence. No further details about the investigation or any contributing factors have been released at this time.
