On 17 February 2025, the MHI RJ Aviation Group. CL-600-2D24 aircraft (CRJ-900LR) (registration N932XJ, serial number 15194) was operating as Endeavor Air flight EDV4819 from Minneapolis-Saint Paul International/Wold-Chamberlain Airport (KMSP), Minnesota, United States, to Toronto/Lester B. Pearson International Airport (CYYZ), Ontario.
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 Runway 15L. Aircraft rescue and fire fighting responded, and all passengers and crew evacuated.
- During the landing on Runway 23, the MHI RJ Aviation Group. CL-600-2D24 aircraft (CRJ 900LR) 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 Runway 15L of Pearson International Airport (CYYZ), Ontario.
- 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 first officer has worked for Endeavor Air since January 2024. She holds an airline transport pilot certificate issued by the FAA. At the time of the occurrence, she had accumulated 1422.3 hours total flight time, including 418.7 hours on the aircraft type.
- At the time of the occurrence, captain had accumulated about 3570 hours total flight time, including 764 hours on the aircraft type.
- During approach, at 1412:42 (1.6 seconds before touchdown), the aircraft’s indicated airspeed was 136 knots, and its ground speed was 111 knots.
- 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 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 right wing, including the right MLG, became fully detached from the aircraft and slid approximately 215 feet further along Runway 23.
- The flaps and slats were fully deployed at the time of the occurrence. The flap jackscrew threads were measured to be 10 inches for both the left and right inboard flap actuators (4 locations), which corresponds to 45° of flaps. Based on measurements taken from the left slat, the slats were in a 25° position.
- The aircraft was a CL-600-2D24 (Regional Jet Series 900) manufactured by Bombardier Inc. in 2008 and registered to Delta Air Lines, Inc. on 31 December 2009.
- The occurrence landing weight was approximately 73 000 pounds, and there was about 6000 pounds of fuel remaining at the time of landing.
- The aircraft came to rest inverted; as a result, passengers were hanging upside down in their seats, suspended by their safety belts, and many of the carry-on baggage and other items ended up on the aircraft ceiling (Figure 8).
- Some passengers had difficulty releasing the buckles on their safety belts due to being inverted. Some of the injuries sustained by the passengers occurred when they unbuckled their safety belts and fell to the ceiling.
-After the passengers and crew evacuated, ARFF personnel entered the fuselage. Shortly thereafter, an explosion occurred outside the aircraft in the area of the left wing root. The cause of this explosion has yet to be determined.
