Delta plane that crashed at Pearson airport was travelling at high rate of descent, prelim report suggests | CBC News

A warning system on the Delta Air Lines flight that crashed at Pearson airport last month sent an alert indicating a high rate of descent less than three seconds before the plane touched down, according to a preliminary report.

Darn it - no link to the actual report and I hate newspaper and ambulance chaser interpretations of any report. I will see if I can find it tomorrow - too tired now.

View preliminary reportThe occurrenceOn 17 February 2025, a CRJ-900 aircraft, manufactured by Bombardier, operated by Delta Endeavor Air, was conducting a flight from Minneapolis–Saint Paul International Airport, Minnesota, to Toronto/Lester B. Pearson International Airport (CYYZ), Ontario.

But their web design is practically falling apart. Going off what I could see from the assets that loaded, the rate of descent was too fast and the right gear collapsed.

A Admiral Beez and cammerjeff (and myself) were right about the rate of descent being too fast. But certainly there were other conditions which caused the collapse of the landing gear. Ice and snowy conditions are known to specifically make landing more problematic because they can lead to faster descent rates.

Accidental double post sorry guys

Thanks for the link. An excellent prelim report. Why they were landing at 150% of max decent rate with one wing low is yet to come. I am thinking that if they had landed on both mains simultaneously it is possible there would not have been any survivors.

Good video thank you for sharing! The comments are brutalizing the pilot and co-pilot, but I wonder what came out of their debriefings because as said in the video, their instrumentation may or may not have given accurate readings.

The only real critique to me was the crew's missing the sink-rate issue, because Lemoine praised their performance otherwise. And I think missing +500' sink rate on an approach is fair to critique.

Instrumentation should not be an issue as the critical instruments are duplicated and totally independent as in what the Capt sees and the FO sees come from two different sources. That way if one source fails the crew should quickly pick that variation in readings up and then follow the appropriate checklist. In an aircraft this modern the BITE system should throw an alert if the instruments are out by more than a minor amount.
