Poor Visibility, Cloud Cover, Runway Lapse… What Actually Triggered The LaGuardia Collision?

New Delhi: LaGuardia Airport in New York became the scene of a rare and serious runway incident late on Sunday night. An Air Canada Express CRJ-900, operated by Jazz Aviation, arriving from Montreal as flight AC8646, collided with an Airport Rescue and Fire Fighting (ARFF) vehicle while rolling down Runway 4 after landing. 

How the Incident Unfolded 

According to flight tracking data from Flightradar24, the aircraft touched down normally and began decelerating along the runway. At the same time, ATC audio captured by LiveATC.net revealed that the ARFF truck had been cleared to cross Runway 4 at taxiway D. The tower controller can be heard urgently instructing “Truck 1” to stop multiple times, but the vehicle continued across the runway. Within seconds, the aircraft struck the truck at a ground speed of roughly 24 miles per hour (39 km/h). 

Immediate Aftermath 

The collision caused visible damage to the nose of the aircraft, as shown in unverified footage circulating on social media. Emergency response teams rushed to the scene, and the Federal Aviation Administration (FAA) issued an immediate ground stop at LaGuardia. Initially set until 0530 GMT, the halt was later extended, with advisories suggesting the airport could remain closed until 1800 GMT. The shutdown disrupted operations at one of New York’s busiest airports. 

Authorities said the incident happened around 11:40 p.m. when Flight AC8646, a Jazz Aviation service operating for Air Canada, landed on Runway 4 after departing Montréal-Pierre Elliott Trudeau International Airport. The plane, carrying 72 passengers and four crew members, collided with a Port Authority Aircraft Rescue and Firefighting vehicle that was responding to a separate emergency.

The Port Authority confirmed its police department, chairman, and executive director were on site as investigators worked to secure the runway. LaGuardia was closed immediately following the crash, with operations suspended while officials assessed the damage and safety conditions.

Air Canada and Jazz Aviation issued statements acknowledging the accident, noting that passenger and crew counts were preliminary and subject to confirmation. No official word was given on injuries or fatalities.

Images and videos posted on social media showed the jet’s nose severely damaged, illuminated by floodlights as emergency vehicles surrounded the aircraft. The wreckage scene underscored the seriousness of the collision, which disrupted one of New York City’s busiest airports.

Aircraft and Crew 

The aircraft involved was a CRJ-900LR registered C-GNJZ, delivered new to Jazz Aviation in 2005. While details on injuries have not yet been confirmed, reports suggest that several people have sustained injuries and there are reports of fatalities. 

Authorities are assessing the extent of the damage and investigating how a rescue vehicle ended up crossing an active runway during landing operations. 

The FAA, Air Canada, and New York Fire Department have yet to issue detailed statements, but investigators will be looking closely at communication protocols and procedural lapses. 

The Bigger Picture 

LaGuardia is a vital hub for domestic flights, and any prolonged closure has cascading effects across the US air travel system. For passengers, the incident meant delays and diversions and for aviation authorities, it is a stark reminder of how quickly routine operations can turn into emergencies.
