Key Takeaways:
A preliminary report from the National Transportation Safety Board (NTSB) on the fatal March 22 crash at LaGuardia Airport revealed that a series of communication and technology failures preceded the collision between an Air Canada Express jet and an airport firetruck that resulted in two fatalities.
The turret operator in the Oshkosh Striker 1500 firetruck told investigators he heard the air traffic controller’s calls to “stop stop stop” but did not know the transmission was for his vehicle until it had already entered the runway, according to the report. The crash killed the captain and first officer of the aircraft.
The NTSB found that the airport’s surface detection system, known as ASDE-X, did not generate an alert for controllers because the seven emergency vehicles responding to a separate incident lacked transponders. The system was “unable to establish high-confidence tracks” and displayed only two radar targets instead of seven, preventing it from correlating the truck's path with the landing airplane.
The crash involved Jazz Aviation flight 646, a CRJ-900 airplane, which was cleared to land on runway 4. At the same time, seven emergency vehicles were responding to another aircraft's emergency near terminal B. The lead firetruck, Truck 1, was cleared to cross the runway while the Air Canada flight was just 130 feet from the ground and about a quarter-mile from the intersection. Despite the controller issuing two separate "stop" commands, the truck continued onto the runway, where the collision occurred at a speed of 104 mph.
The NTSB's investigation is scrutinizing the airport's safety protocols and technology. LaGuardia is one of 20 US airports equipped with a Runway Status Light (RWSL) system, which illuminates red lights on taxiways when a runway is occupied. The lights were on as the truck approached but extinguished about three seconds before the collision, as they are designed to do when a plane is about to pass the intersection.
Investigators are also reviewing the actions of the two air traffic controllers on duty, who had 18 and 19 years of experience, respectively. The local controller was handling communications on both ground and tower frequencies as the other controller was coordinating the initial emergency.
The crash resulted in 39 people being transported to local hospitals, with six serious injuries reported in addition to the two pilot fatalities. The NTSB’s final report, which will include a probable cause, is expected in 12 to 24 months.
This incident highlights the potential for catastrophic failure when airport ground vehicles are not equipped with modern tracking technology. The lack of transponders on the LaGuardia ARFF vehicles is a critical point of investigation that could lead to new safety mandates for airports nationwide.
