Air Canada Express jet collides with fire truck at LaGuardia, killing two pilots

An Air Canada Express regional jet collided with a fire truck while landing at New York’s LaGuardia Airport at 11:45 p.m. EDT on Sunday, March 22, 2026, killing both pilots and hospitalizing 41–43 passengers and crew. The impact severed the cockpit from the fuselage. Air traffic control audio confirms the controller cleared the fire truck to cross Runway 4, then frantically ordered it to stop seconds before collision — the controller later stated, “I messed up.” Runway 4 remains closed through Friday, March 27, cutting LaGuardia’s capacity by roughly 40%.

The NTSB has retrieved both black boxes and confirmed the cockpit voice recorder is undamaged. Flight data recorder examination begins Tuesday, March 25. This is LaGuardia’s first fatal crash in 30 years, and the runway closure is forcing cascading cancellations across all carriers using the airport — not just Air Canada.

Air Canada Express Flight 8646, a CRJ 900 carrying 72 passengers and 4 crew from Montreal, struck a Port Authority fire truck on Runway 4 at LaGuardia while landing just before midnight Sunday. The aircraft was traveling between 93–105 mph at impact.

Both pilots — Canadian nationals — were killed instantly. The collision severed the cockpit and tore open the fuselage, ejecting a flight attendant through the opening while she was still strapped to her seat. She survived with serious injuries. 41 to 43 people were hospitalized with injuries ranging from broken bones to one brain bleed.

The fire truck had been cleared to cross the runway to respond to a separate emergency — United Airlines Flight 2384 had aborted takeoff due to an anti-ice warning and cabin odor. Air traffic control audio captures the controller frantically ordering the truck to stop: “Stop, stop, stop, Truck 1.” Seconds later, the collision occurred. Roughly 20 minutes after the crash, the same controller can be heard saying, “I was dealing with an emergency earlier and I messed up.”

Runway 4 is closed through 5 a.m. Friday, March 27. LaGuardia reopened one runway Monday afternoon, but the airport is operating at roughly 60% capacity. All carriers using LaGuardia — United, American, Delta, Southwest, JetBlue, and Air Canada — face multi-day delays and cancellations as aircraft and crews are repositioned.

NTSB investigation confirms controller error, black boxes retrieved

The National Transportation Safety Board arrived on-site within hours and has taken custody of the cockpit voice recorder and flight data recorder. The CVR is confirmed undamaged and has been transported to NTSB labs in Washington, D.C. Flight data recorder examination begins Tuesday, March 25, with preliminary findings expected within 30 days.

Transport Canada and representatives from Air Canada and Jazz Aviation (the regional carrier operating the flight) are also participating in the investigation. The focus is on air traffic control clearance protocols and whether staffing levels or procedural gaps contributed to the collision.

This is LaGuardia’s first fatal accident in 30 years. Runway incursions — when aircraft, vehicles, or people enter an active runway without clearance — are tracked by the FAA, but catastrophic outcomes like this are rare. Most are resolved through pilot awareness or controller intervention before impact occurs.

How air traffic control protocols failed

Air traffic controllers manage runway crossings through a strict clearance sequence: vehicles request permission, controllers verify no conflicting aircraft movements, then issue explicit clearance with the runway number and crossing point. The system depends on controllers maintaining situational awareness across multiple simultaneous events.

In this case, the controller was managing two emergencies — the United Airlines aborted takeoff and the incoming Air Canada flight. Audio recordings suggest the controller cleared the fire truck to cross Runway 4, then realized the conflict seconds too late. The frantic “stop” commands came after the truck had already entered the runway, and the aircraft was on final approach at over 90 mph — too fast and too close to abort the landing.

The FAA mandates runway incursion prevention systems at major airports, including ground radar and conflict alert software. LaGuardia has these systems, but they depend on controllers acting on the alerts. If the NTSB finds the controller ignored or missed a system warning, expect immediate FAA mandates for enhanced training and potentially automated runway closure protocols when conflicts are detected.

What to do if your flight is affected

LaGuardia’s capacity constraints through Friday mean proactive action is required — waiting for the airline to contact you wastes rebooking options.

• Contact your airline immediately — Air Canada: 1-888-247-2262, United: 1-800-864-8331, American: 1-800-433-7300, Delta: 1-800-221-1212. Request rebooking to JFK or Newark, or a full refund if no acceptable alternative exists within 24 hours.
• Check alternate airports now — JFK and Newark are absorbing displaced traffic, but capacity is finite. If your airline offers a same-day reroute, take it — tomorrow’s options will be worse.
• Invoke passenger rights — Canadian APPR applies to Montreal-origin flights (rebooking at no cost, meals/accommodation if delay exceeds 3 hours). US DOT rules apply to US-origin flights (rebooking required, but compensation not mandated for extraordinary circumstances).

• Document everything — Save all rebooking confirmations, receipts for meals/hotels, and communication with the airline. If you’re forced to purchase a new ticket on another carrier, keep the receipt — some credit cards cover this under trip delay insurance.

Watch: NTSB preliminary findings expected within 30 days. If the investigation confirms air traffic control staffing gaps or procedural failures, the FAA may mandate immediate controller augmentation and runway incursion prevention system upgrades — which could extend delays beyond March 27.
