Quick summary
Air Canada Express Flight 8646 collided with a Port Authority fire truck on LaGuardia Airport’s Runway 4 at 11:47 p.m. ET on March 22, 2026, killing both pilots and injuring 43 others including passengers and firefighters. A flight attendant survived ejection from her seat during impact. The runway remains closed until 7 a.m. ET Friday, March 27, forcing LaGuardia to operate on reduced capacity with widespread delays and cancellations across all carriers.
Air Canada and major airlines have waived rebooking fees for affected passengers. The NTSB preliminary report is expected within 30 days — if air traffic control error is confirmed, expect enhanced vehicle control procedures at LaGuardia.
A CRJ-900 regional jet carrying 72 passengers from Montreal struck an airport fire truck seconds after landing at LaGuardia late Sunday night, killing the aircraft’s two pilots and turning a routine arrival into one of the deadliest U.S. airport ground collisions in years. The vehicle had been cleared to cross Runway 4 but was ordered to stop moments before the 105 mph impact.
Thirty-two injured passengers have been released from New York hospitals. Two firefighters aboard the truck survived.
The collision closed LaGuardia entirely until 2 p.m. Monday, March 23, then reopened on a single runway. Runway 4 — where the crash occurred — will not reopen until Friday morning at 7 a.m. ET, according to FAA notices. That four-day closure is forcing airlines to cancel or delay hundreds of flights as LaGuardia operates at roughly half capacity.
What happened on Runway 4
Air Canada Express Flight 8646, operated by Jazz Aviation, touched down on Runway 4 around 11:45 p.m. ET after a short hop from Montreal. The aircraft was decelerating when it struck a Port Authority Aircraft Rescue and Firefighting vehicle that had been dispatched to respond to an earlier aborted takeoff by a United Airlines flight.
Air traffic control had cleared the fire truck to cross the runway but issued a stop command seconds before impact — too late for the 30-ton vehicle to clear the path. The NTSB is investigating whether the clearance was premature or whether the vehicle crew misunderstood instructions.
Both pilots — a captain and first officer whose names have been released to families but not yet publicly — died on impact. A flight attendant was ejected from her seat during the collision but survived with serious injuries. Her daughter told Australian media the survival felt miraculous given the force of the crash.

The regulatory layer behind airport vehicle movements
The FAA certifies LaGuardia’s operations and oversees U.S. air traffic control — including the clearances given to the fire truck that night. The NTSB investigates accidents like this runway incursion and issues safety recommendations that the FAA can mandate as procedural changes.
Transport Canada certifies Air Canada and its regional partner Jazz Aviation under Canadian Aviation Regulations, with annual audits. The FAA audits foreign carriers operating in the U.S. through an IOSA-aligned process. A 2025 FAA audit rated LaGuardia “acceptable” for Aircraft Rescue and Firefighting readiness. A 2025 Transport Canada audit gave Jazz Aviation no major findings — the carrier holds current IOSA certification.
The NTSB will release a preliminary report within 30 days, followed by a full report in 12 to 24 months. Any findings trigger FAA or Transport Canada mandated fixes — typically ATC training updates or vehicle movement protocol changes.
Rebook now or wait at reduced capacity
LaGuardia operates on one runway through Thursday night — delays and cancellations will cascade across all carriers as the airport handles roughly half its normal traffic volume.
- Check flight status immediately: Use airline apps or FlightAware to confirm your departure has not been canceled. LaGuardia delays are system-wide, not limited to Air Canada.
- Use rebooking waivers: Air Canada, Delta, American, United, and JetBlue have waived change fees for LaGuardia flights through March 27. Rebook to JFK or Newark at no penalty — both airports operate at full capacity.
- Avoid positioning to LaGuardia: If you planned to connect through LaGuardia this week, reroute through JFK or Newark now. Single-runway ops mean missed connections are likely.
- Monitor the Friday reopening: If Runway 4 reopens as scheduled at 7 a.m. ET on March 27, normal operations resume immediately. Check FAA NOTAMs Thursday evening for confirmation.
Watch: The NTSB’s initial findings within 72 hours of the crash — by March 25 — will signal whether air traffic control procedures at LaGuardia face immediate changes that could slow operations further.
Questions? Answers.
Can I get a refund if my LaGuardia flight is canceled this week?
Yes. U.S. DOT rules require airlines to offer refunds for cancellations exceeding 3 hours. Contact your airline within 24 hours of notification. Air Canada and U.S. carriers have also waived change fees for rebooking to alternate airports like JFK or Newark.
Is Air Canada suspending flights to LaGuardia after this crash?
No. Air Canada has not announced any fleet-wide or route changes. The carrier operates multiple daily flights to LaGuardia from Toronto and Montreal — those flights continue on the airport’s single operational runway, though delays are expected through March 26.
What caused the fire truck to be on the runway during landing?
The truck was responding to an earlier aborted takeoff by a United Airlines flight. Air traffic control cleared the vehicle to cross Runway 4 but issued a stop command seconds before the Air Canada jet landed — too late to prevent the collision. The NTSB is investigating whether the clearance was premature or whether the vehicle crew misunderstood instructions.
How long will LaGuardia operate on one runway?
Runway 4 is scheduled to reopen at 7 a.m. ET on Friday, March 27, 2026. If the NTSB extends the closure for investigation purposes, the FAA will issue an updated NOTAM. Check airline notifications or FlightAware for real-time status.
