An Air Canada Express regional jet collided with a Port Authority Aircraft Rescue and Firefighting vehicle on a runway at New York’s LaGuardia Airport late on Sunday, March 23, 2026, killing both pilots and injuring dozens of passengers, crew, and airport personnel. The collision forced the immediate closure of LaGuardia Airport, New York City’s third-busiest aviation hub, and triggered a joint investigation by United States and Canadian transportation safety authorities.
Air Canada Flight 8646, operated by Jazz Aviation under the Air Canada Express brand, was carrying 72 passengers and four crew members on a route from Montreal Trudeau International Airport in Canada. The aircraft, an Air Canada Express CRJ-900, touched down at LaGuardia Airport at approximately 11:40 p.m. Eastern Time and struck the Port Authority emergency vehicle moments after landing on Runway 4. Preliminary data from flight tracking service FlightRadar24 indicates the jet was travelling at between 93 and 105 miles per hour at the time of impact with the fire truck.
Port Authority of New York and New Jersey Executive Director Kathryn Garcia confirmed at a press conference held in the early hours of Monday, March 23, 2026 that the pilot and first officer of Air Canada Flight 8646 were both killed in the collision. Garcia said that 41 passengers and crew members were transported to local hospitals following the incident. Of those hospitalised, 32 had subsequently been released, though Garcia noted that some passengers sustained serious injuries. Two Port Authority officers aboard the fire rescue vehicle suffered broken bones but were expected to survive, according to officials.
Air traffic control audio recordings reviewed by multiple news organisations revealed the sequence of events that led to the collision. A separate aircraft, United Flight 2384, had aborted a takeoff on the other side of LaGuardia Airport after a warning light activated and the pilots reported an unusual odour in the cabin that had made flight attendants ill. The Port Authority Aircraft Rescue and Firefighting vehicle was dispatched from the airport fire station to respond to the United Airlines emergency and was granted permission by air traffic control to cross Runway 4. Seconds before the collision, an air traffic controller issued an urgent order for the fire truck to stop before declaring that a collision had occurred on the airfield.
A flight attendant aboard Air Canada Flight 8646 was found outside the aircraft, still strapped into her seat, having been ejected by the force of the collision. Her condition was not immediately confirmed by officials. Photographs and video footage from the scene showed severe structural damage to the nose section of the CRJ-900 regional jet. Passengers were observed standing on the wing of the aircraft in the aftermath of the collision, and passenger accounts described a chaotic evacuation conducted without guidance from either pilot, both of whom had died in the impact. One passenger, Jack Cabot, told media that several people around him were bleeding from head injuries sustained in the collision.
The Federal Aviation Administration issued a ground stop at LaGuardia Airport immediately after the collision, citing an aircraft emergency. The airport was declared closed until at least 2:00 p.m. Eastern Time on Monday, March 23, 2026, to allow for emergency response operations and the commencement of a formal aviation safety investigation. LaGuardia Airport is the third-busiest airport serving the New York metropolitan area and recorded approximately 900 inbound and outbound flights per day in January 2026, according to Port Authority operational data. The airport’s temporary closure compounded existing disruptions to United States air travel caused by a partial government shutdown affecting the Department of Homeland Security, which had left Transportation Security Administration officers working without pay for six consecutive weeks.
What caused the Air Canada Flight 8646 collision with the Port Authority fire truck at LaGuardia Airport?
Based on information available from air traffic control audio and preliminary statements from the Port Authority of New York and New Jersey, the fire truck involved in the collision had been formally cleared by an air traffic controller to cross Runway 4 while responding to the separate United Airlines emergency. Aviation safety analysts noted that runway incursions involving ground vehicles, while not unprecedented, are a rare occurrence at major commercial airports. Jeff Guzzetti, a retired aviation accident investigator and NBC News aviation analyst, described the incident as likely an operational issue involving the controller, the vehicle operator, or both, and said he could not recall a previous runway collision between a commercial aircraft and a ground vehicle that resulted in critical casualties. The National Transportation Safety Board is leading the United States investigation, while Canadian authorities are participating as a party to the inquiry given that the aircraft was operated by a Canadian carrier.
How did United States and Canadian government officials respond to the LaGuardia Airport runway collision on March 23, 2026?
United States Transportation Secretary Sean Duffy stated on social media platform X that he was travelling to LaGuardia Airport in response to what he described as a horrific crash and confirmed that the Federal Aviation Administration and the National Transportation Safety Board were working closely on the investigation. Duffy shared imagery of the aircraft wreckage at the scene.
Canadian Prime Minister Mark Carney issued a public statement describing the collision as deeply saddening and confirmed that Canadian transportation safety officials were working in close coordination with their United States counterparts at the LaGuardia Airport site. Carney expressed condolences to the families of the victims and all those affected by the incident. Both the United States National Transportation Safety Board and the Transportation Safety Board of Canada dispatched investigative teams to the scene.
United States President Donald Trump, speaking to reporters before boarding Air Force One at Palm Beach International Airport in West Palm Beach, Florida, commented briefly on the collision, calling it terrible and stating that a mistake had been made. New York Governor Kathy Hochul described the incident as heartbreaking and expressed condolences to affected families. New York City Mayor Zohran Mamdani confirmed he had been briefed and noted that the National Transportation Safety Board was investigating, adding that the city was in contact with federal, state, and local partners.
What is the role of Jazz Aviation and Air Canada Express in operating regional flights on behalf of Air Canada?
Air Canada Express is the regional aviation brand through which Air Canada markets and sells short-haul and regional flights across North America. Jazz Aviation is one of the principal regional carriers contracted to operate Air Canada Express flights under a capacity purchase agreement. Jazz Aviation operates CRJ-series regional jets, including the CRJ-900 model involved in the LaGuardia Airport collision, on routes connecting Canadian and United States cities. Air Canada Flight 8646 operated under the Air Canada brand and ticketing system but was staffed and flown by Jazz Aviation crew. Jazz Aviation issued a statement in the early hours of Monday, March 23, 2026 confirming the incident. The Air Line Pilots Association International, the union representing commercial airline pilots in the United States and Canada, issued a statement from President Captain Jason Ambrosi describing the deaths of the two crew members as a profound tragedy.
How does the LaGuardia Airport collision affect United States air travel disruption during the government shutdown in 2026?
The closure of LaGuardia Airport added significant strain to an already severely disrupted United States commercial aviation system. A partial federal government shutdown affecting Department of Homeland Security funding had entered its sixth consecutive week by March 23, 2026. Transportation Security Administration officers, required to continue working without pay under essential worker provisions, had been calling out from their posts in increasing numbers, resulting in chronic staffing shortfalls at security checkpoints across American airports. LaGuardia’s largest carrier, Delta Air Lines, warned travellers to expect significant flight disruptions as a result of the airport closure. LaGuardia is ranked as the 19th busiest airport in the United States according to Federal Aviation Administration data for 2024.
Newark Liberty International Airport in New Jersey, one of the other major airports serving the New York metropolitan area, also briefly issued a ground stop on the morning of Monday, March 23, 2026, after the air traffic control tower was evacuated due to reports of smoke, compounding delays across the regional aviation network. Air traffic controllers were not affected by the Department of Homeland Security partial shutdown, as their employment falls under a separate federal agency, unlike Transportation Security Administration personnel.
What investigative process will the National Transportation Safety Board lead following the LaGuardia runway collision?
The National Transportation Safety Board of the United States, the independent federal agency responsible for investigating civil transportation accidents, dispatched a go-team to LaGuardia Airport on Sunday night following notification of the collision. The NTSB is leading the investigation given that the accident occurred on United States soil. The Transportation Safety Board of Canada is participating in the investigation as a party, as is consistent with international aviation accident investigation conventions when a foreign-registered aircraft is involved in an accident in another country.
Teams from both Air Canada and Jazz Aviation were also dispatched to LaGuardia Airport to cooperate with investigators. The Federal Bureau of Investigation’s Joint Terrorism Task Force responded to the scene on Sunday night as a precautionary measure, but agents departed after aviation officials confirmed the collision was not a criminal act or terrorist incident. The identities of the two pilots killed in the collision had not been publicly released as of Monday morning, though Port Authority Executive Director Kathryn Garcia confirmed they were both based in Canada. All 72 passengers aboard the flight had been accounted for, Garcia confirmed, and an unaccompanied minor on the aircraft was reunited with their family.
