DL4819 - Accident: Endeavor CRJ9 at Toronto on Feb 17th 2025

An Endeavor Airlines Canadair CRJ-900 on behalf of Delta Airlines, registration N932XJ performing flight DL-4819 from Minneapolis,MN (USA) to Toronto,ON (Canada) with 76 passengers and 4 crew, landed on Toronto's runway 23 at 14:12L (19:12Z) but came to a stop on the runway inverted, both wings, both main gear and the tailplane separated from the airframe. There were no fatalities, however, one person was critically injured, 7 others received minor injuries.

Toronto Airport reported all people on board have been accounted for.

Emergency services reported one person is in critical condition, 7 others have received injuries.

The Canadian TSB reported: "TSBAir is deploying a team to investigate an aircraft accident at Toronto / Lester B. Pearson International Airport, ON. The TSB will gather information and assess the occurrence."

The NTSB reported: "The NTSB is leading a team of U.S. investigators to assist the Transportation Safety Board of Canada with their investigation of today’s accident of a Delta Air Lines Bombardier CRJ900 at Toronto Pearson International Airport. Per international protocols under the International Civil Aviation Organization's Annex 13, any information about the investigation will be released by the Transportation Safety Board of Canada."

On Feb 18th 2025 the TSB reported the aircraft impacted the runway causing parts of the aircraft to separate from the aircraft and the aircraft to turn upside down. The aircraft came to rest right of the runway. CVR and FDR have already been removed from the aircraft and have been sent to the laboratory.

On Mar 6th 2025 the TSB reported: "During the landing on Runway 23, the aircraft impacted the runway, the right wing detached and a fire ensued. The aircraft overturned, and slid down the runway inverted, coming to rest near the intersection of Runway 23 and 15L."

On Mar 18th 2025 the TSB announced: "Tomorrow (Mar 20th 2025) the TSB will be releasing a preliminary report into the Toronto Pearson airport’s Delta occurrence (A25O0021). "

On Mar 19th 2025 the TSB released their preliminary report and a video (see below) summarizing the sequence of events:

At 12471 on 17 February 2025, the MHI RJ Aviation Group. CL-600-2D24 aircraft (CRJ 900LR) operated by Endeavor Air (doing business as Delta Connection) departed Minneapolis-St. Paul International/Wold-Chamberlain Airport (KMSP), Minnesota, United States, on flight EDV4819, an instrument flight rules flight to Toronto/Lester B. Pearson International Airport (CYYZ), Ontario, with 2 flight crew members, 2 cabin crew members, and 76 passengers on board. The captain was seated in the left seat and was the pilot monitoring for the flight. The first officer was seated in the right seat and was the pilot flying (PF).

The flight proceeded uneventfully, and the crew received clearance for the instrument landing system approach to Runway 23 at CYYZ. The landing reference speed (VREF) for the approach was 139 knots.

According to Endeavor Air’s CRJ700/900 Series Company Flight Manual, “Final approach is flown at VREF+5 knots. When operating in gusty wind conditions, increase VREF by 1/2 of the gust factor not to exceed 10 KIAS [knots indicated airspeed] (top of the bug).”2 On the occurrence flight, the flight crew set the speed bug to VREF+5 knots, or 144 knots. Given the reported wind gusts, the approach was flown at 149 knots.

At 1412:01, the aircraft descended through 500 feet above ground level (AGL). The aircraft’s indicated airspeed was 150 knots, its ground speed was 121 knots, and the engine thrust was indicating approximately 64% N1.3 The rate of descent was 720 fpm, and the localizer and glide slope were centred. Five seconds later, the PF disconnected the autopilot.

At 1412:26, while the aircraft was descending through 175 feet AGL, its indicated airspeed was 144 knots, with a ground speed of 121 knots, and a rate of descent of 672 fpm. The thrust remained at approximately 64% N1.

At 1412:30, while the aircraft was descending through 153 feet AGL, its indicated airspeed increased to 154 knots whereas the ground speed did not change appreciably, consistent with a performanceincreasing wind gust. The PF pulled back the thrust levers, and as a result, over the following 5 seconds, N1 decreased from 64% to approximately 43%, where it remained until touchdown. The airspeed began to decrease.

At 1412:40 (3.6 seconds before touchdown), when the aircraft was at a height of 50 feet AGL, the indicated airspeed was 145 knots, and the ground speed was 112 knots. The rate of descent had increased to 1114 fpm. The enhanced ground proximity warning system (EGPWS) aural alert “fifty” sounded to indicate the aircraft was at 50 feet AGL, which is a standard callout.

One second later (2.6 seconds before touchdown), the EGPWS alert “sink rate” sounded, indicating a high rate of descent. The aircraft’s indicated airspeed was 136 knots, its ground speed was 111 knots, and the rate of descent had remained at about 1100 fpm. The bank angle increased to a 4.7° right bank. The engine thrust was steady at approximately 43% N1.

At 1412:42 (1.6 seconds before touchdown), the aircraft’s indicated airspeed was 136 knots, and its ground speed was 111 knots. The aircraft was slightly below the glide slope, but on the visual segment of the approach and tracking the runway centreline. The rate of descent had increased to 1072 fpm, and the bank angle was 5.9° to the right.

Less than 1 second before touchdown, the aircraft’s indicated airspeed was 134 knots, and its ground speed was 111 knots. The bank angle was 7.1° to the right, and the pitch attitude was 1° nose up. The rate of descent was recorded as 1110 fpm.

At 1412:43.6, the right main landing gear (MLG) contacted the runway. The aircraft was in a 7.5° bank to the right with 1° of nose-up pitch and 3g vertical acceleration, at a rate of descent of approximately 1098 fpm (18.3 fps).

At touchdown, the following occurred: the side-stay that is attached to the right MLG 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 exact sequence of these events is still to be determined by further examination of the fracture surfaces.

The aircraft then began to slide along the runway. The fuselage slid down Runway 23, rolling to the right until it became inverted. A large portion of the tail, including most of the vertical stabilizer and the entire horizontal stabilizer, became detached during the roll.

The aircraft went off the right side of the runway into the snow-covered grass area and came to a rest on Runway 15L, near the intersection with Runway 23, about 75 feet beyond the right edge of Runway 23 (Figure 1). The right wing, including the right MLG, became fully detached from the aircraft and slid approximately 215 feet further along Runway 23.

Once the aircraft came to a stop, an evacuation began. All occupants evacuated the aircraft. At the time of writing this preliminary report, it has been confirmed that 21 of the 80 occupants were injured; 2 of those occupants were reported to have serious injuries.
