Delta Connection 4819: the jet that flipped over at Toronto — and everyone got out

What happened

Endeavor Air flight 4819, flying as Delta Connection from Minneapolis–St. Paul, was landing on Runway 23 at Toronto Pearson at about 2:12 p.m. Winds were from the west at 28 knots gusting to 35, with blowing snow.¹

According to the TSB's preliminary data:¹

• About 3.6 seconds before touchdown, the jet was descending at roughly 1,100 feet per minute. The ground proximity warning system called "sink rate."
• The right main landing gear touched down first, with the aircraft banked 7.5° to the right. The gear's shock absorbers are designed to absorb a 720 ft/min descent at maximum landing weight.
• A gear brace (side-stay) fractured, the gear folded, the right wing separated, and released fuel caught fire. The fuselage rolled over and slid to a stop upside down beside the runway.

All 80 people got out. 21 were injured, 2 of them seriously.¹

What we know about the evacuation

• Passengers were hanging upside down in their seat belts; some were hurt when they unbuckled and fell to the ceiling. The TSB said it was not aware of any seat or belt failures.¹
• The pilots exited through the cockpit's emergency roof hatch. Passengers and cabin crew left through the right forward door and an overwing exit. Airport firefighters arrived about five minutes after the accident.^{1, 2}

How rare is this?

Airliners overturning on landing are extremely unusual. The TSB has said it is analysing similar occurrences worldwide on other aircraft types as part of the investigation.² And as the box on this page shows, accidents of any kind happen roughly once per 760,000 flights — most of them far less dramatic than this.

What's being looked at

The TSB's areas of investigation include the wing and landing-gear structure and certification, hard-landing technique and pilot training, evacuation procedures when an aircraft is inverted, the cockpit's secondary exit, and the emergency response.¹ As of its February 2026 update, metallurgical testing was complete and analysis, simulator work and report drafting were continuing.²
