An Air Canada Express (operated by Jazz Aviation) CRJ-900 collided with an Airport Rescue and Fire Fighting vehicle while landing at New York’s La Guardia Airport (LGA) late Sunday, 22 March. Flight AC8646 from Montreal landed on Runway 4 and was rolling down the runway when it struck the ARFF apparatus as it crossed the runway.
The emergency vehicle reportedly was responding to a United aircraft that had reported fumes onboard.
ATC audio captured by LiveATC.net indicates the ARFF truck was cleared to cross Runway 4 at taxiway D. The tower controller can be heard telling “Truck 1” to stop multiple times before dispatching additional ARFF units on the airfield to the scene.
Granular data from the aircraft indicates a gradual deceleration on the runway until the aircraft reaches Taxiway E. At that point the aircraft’s ground speed decreases quickly and the reported track changes.
Truck lacked transponder
In their post-incident briefing, the NTSB said that the emergency vehicle involved in the collision wasn’t equipped with a transponder. While LaGuardia is equipped with ASDE-X technology, no alert was triggered for the ATC staff in the tower.
ASDE-X is a surface surveillance system that integrates radar and transponder data to track aircraft and vehicles and provide automated runway incursion alerts to air traffic controllers.
Casualties reported
Images purportedly showing what remains of the aircraft is circulating in social media. The entire front of the aircraft was demolished, suggesting a high-speed collision. The Port Authority of New York and New Jersey have confirmed that both pilots died in the accident, and that 41 people were taken to hospital.
The operator of Air Canada Express flight 8646, Jazz Aviation, has disclosed that the preliminary passenger list revealed that the aircraft carried 72 passengers and four crew members.
La Guardia remained closed for operations until 2 PM (18:00 GMT) on Monday and has since re-opened.

Flight data recorder has been found
In a press conference held in the evening (local time) of March 23rd, the National Transportation Safety Board (NTSB) stated that the flight data recorder (FDR) as well as the cockpit voice recorder (CVR) had been retrieved from the aircraft. Both units have been transported to Washington DC, and are expected to be analyzed as part of the investigation.
25 hours worth of CVR data was recorded and 80 hrs of FDR data, along with hundreds of parameters, according to the NTSB. It will be analyzed and transcribed on March 25th.
