Pearson plane crash probe reports simulator tests but cause remains undetermined

The Transportation Safety Board says simulator exercises and metallurgical testing have been done in its investigation of a Delta CRJ900 crash at Toronto Pearson, but investigators have not yet reached a definitive cause and a final report is pending.

The Transportation Safety Board (TSB) provided an update on its investigation into a Delta-operated CRJ900 crash at Toronto Pearson nearly a year after the event. Investigators have carried out simulator exercises at the operator's facility and completed metallurgical examinations of wing and landing gear components. Wreckage was moved from the accident site to a hangar at Pearson, with key pieces later sent to the TSB Engineering Laboratory in Ottawa for testing. The TSB said it is too early to make definitive determinations and that a final report will be issued when the investigation is complete. What investigators reported: - The investigation team conducted simulator exercises examining approach profile, speeds and thrust settings, and analysis of those simulations is ongoing. - A comprehensive metallurgical examination of fracture surfaces on the wing and landing gear has been completed. - The right wing, landing gear, wing box structure and other components were moved to the TSB Engineering Laboratory for further testing. - The crash on Feb. 17, 2025, involved a Delta-operated CRJ900 arriving at Pearson; parts of the aircraft separated and a post-landing fire was reported, and 21 passengers and crew were injured. Summary: The TSB has carried out both simulation work and laboratory examinations that will contribute to the investigative record. Undetermined at this time.
