Air Canada Express Flight AC8646 Hit a Fire Truck at LaGuardia — and Lives Were Lost

A regional jet carrying 76 people collided with a fire truck on a runway at LaGuardia Airport late Sunday night — and the crash has sent shockwaves through one of the country’s busiest aviation corridors.

Air Canada Express Flight AC8646, a Bombardier CRJ-900 operated by Jazz Aviation, had just touched down from Montreal when it struck a Port Authority Aircraft Rescue and Firefighting (ARFF) vehicle on Runway 4 at approximately 11:38 p.m. ET on March 22, 2026. The aircraft was carrying 72 passengers and four crew members at the time of impact.

The collision resulted in fatalities and serious injuries, triggering an immediate emergency response and plunging New York’s air travel network into severe disruption.

What Happened on Runway 4 at LaGuardia

According to available information, the ARFF truck had been cleared to cross Runway 4 in connection with a separate emergency involving another aircraft. As the Air Canada Express jet landed, the two vehicles met on the runway.

Air traffic controllers reportedly issued urgent calls to stop the truck before impact, but the collision could not be prevented. The aircraft struck the ARFF vehicle at a ground speed of 24 mph (39 km/h) — slow by flight standards, but more than enough to cause catastrophic structural damage to a regional jet.

The ARFF truck, designed to respond to aircraft emergencies, was itself destroyed or severely damaged in the collision. The crash represents a grim irony: a vehicle built to save lives at an airport became central to one of the airport’s most serious incidents in recent memory.

Key Facts About Flight AC8646 and the Collision

• The ARFF truck had been cleared to cross the runway for a separate emergency involving another aircraft
• Air traffic controllers issued urgent instructions to stop the truck before the collision occurred
• The crash resulted in fatalities and casualties among crew and first responders
• The aircraft sustained catastrophic damage on impact

Who Was Affected — and How Badly

The human toll from this crash is significant. The full casualty count had not been completely detailed in the initial reporting, but officials described the outcome as a tragic one.

For the 72 passengers on board, the moments following the collision would have been terrifying. A nighttime runway collision at speed — even a relatively low ground speed — produces violent forces inside a regional aircraft cabin. Emergency services responded to the scene, and survivors were evacuated from the aircraft.

The Port Authority personnel operating the ARFF vehicle were also directly in the path of the collision. First responders who had been deployed to manage a separate emergency found themselves at the center of a second, far more serious one.

LaGuardia’s Travel Network Thrown Into Chaos

LaGuardia Airport is one of the most heavily trafficked aviation hubs in the United States, serving millions of passengers each year and operating as a critical gateway for business and leisure travelers moving in and out of New York City. A runway collision of this magnitude doesn’t just affect one flight — it ripples outward across an entire regional network.

Following the crash, the airport faced severe operational disruptions. Runway closures, emergency vehicle deployments, and the scale of the incident response would have halted or significantly delayed operations across the airport. Travelers with flights scheduled through LaGuardia on the night of March 22 and into March 23 faced a deeply uncertain situation.

Airlines operating connecting routes through LaGuardia — and passengers relying on the airport to reach destinations across the Northeast — were caught in cascading delays with little immediate clarity on when normal operations would resume.

What Investigators Will Be Looking At

Runway incursions — incidents where vehicles or aircraft enter a runway without proper clearance — are among the most closely studied categories of aviation safety events. In this case,

Aviation investigators will also examine the air traffic controller’s attempt to stop the truck, the timeline between that instruction and the collision, and whether any procedural failures contributed to the tragedy. Investigations of this nature typically involve the National Transportation Safety Board (NTSB), the FAA, and the operating airline.

The results of that investigation will likely have implications not just for LaGuardia, but for runway crossing procedures at busy airports across the country.
