Delta plane's landing gear collapsed during Toronto crash-landing, investigators say
Investigators say the Delta jet was descending at a high rate of speed

The Delta Air Lines plane that landed upside down in Toronto in February suffered a landing gear collapse as it made contact with the runway, according to a new report.

Investigators released a preliminary report on the crash on Thursday, saying the jet had descended at a high rate of speed, triggering a safety alarm to go off in the cockpit just 2.6 seconds before landing. The plane's right main landing gear collapsed on contact with the runway.

"At touchdown, the following occurred: the side-stay that is attached to the right [main landing gear] fractured, the landing gear folded into the retracted position, the wing root fractured between the fuselage and the landing gear, and the wing detached from the fuselage, releasing a cloud of jet fuel, which caught fire," the report stated.

"The exact sequence of these events is still to be determined by further examination of the fracture surfaces," it clarified.

I'd say that there is a definite need for sweeping and thorough inspections.  Any plane that doesn't pass a rigid inspection needs to be taken off the airfield, repaired and re-inspected before making another flight.

The landing gear may of collapsed because the plane was descending too fast.

'Preliminary report into the Delta CRJ-900 crash at Toronto Pearson International Airport last month says the aircraft’s alert system indicated a high rate of descent less than three seconds before touchdown.'

Not all landing gear is created equal. One of the big differences between naval and air force versions of aircraft is that the naval versions have much stronger landing gear to survive carrier landings. With civilian aircraft, I would expect some margin of safety in excess of what might be needed for landings, but all systems have their structural limits. If the rate of descent was too high (and noting that the aircraft did not appear to flare at touchdown), the structural limits of the landing gear were likely exceeded, whether or not there was any defect.
Thankfully it was a "good" landing--none died, most walked away.
Had it been a great landing, the aircraft would have been able to be re-used.
