The Federal Aviation Administration is pursuing the termination of air traffic controllers involved in the March 22 runway collision at LaGuardia Airport that killed both pilots of an Air Canada regional jet, ABC News reported, citing sources familiar with the matter.
The move signals that federal officials have concluded the controllers bore direct responsibility for clearing an airport rescue vehicle onto an active runway while Jazz Aviation Flight 646 was seconds from touchdown. The crash, which occurred at 11:37 p.m. on a Saturday night, killed both pilots and injured dozens of passengers aboard the Air Canada-branded flight.
If the firings go through, they would mark one of the most severe personnel actions the FAA has taken against controllers in recent memory and raise pointed questions about whether the agency's chronic staffing crisis helped set the stage for the disaster.
The National Transportation Safety Board's preliminary report laid out a grim sequence. A controller cleared the rescue vehicle to cross the active runway while the inbound aircraft was roughly a quarter-mile away and just 130 feet above the ground. At that distance and altitude, the crew had almost no time to react.
The collision destroyed the cockpit and forward fuselage. The passenger cabin, however, remained largely intact, and survivors were able to evacuate in an orderly fashion despite catastrophic structural damage to the front of the plane.
Seven airport rescue vehicles were on the runway environment at the time. The airport's surface detection system, known as ASDE-X, failed to display all of them. Worse, the system created no aural or visual conflict alert to warn controllers in the tower of the looming collision, the NTSB found.
The fire truck that was struck lacked a transponder, which rendered it invisible to the ground radar system. Without that electronic signature, the ASDE-X treated the vehicle as if it did not exist.
The tower was not managing a quiet overnight shift. Controllers were simultaneously handling a United Airlines emergency involving aborted takeoffs and reports of odors that had made flight attendants ill. That situation unfolded at the same time the Air Canada jet was on final approach.
Roughly 20 minutes after the collision, a controller transmitted on the radio frequency with a stark admission.
"We were dealing with an emergency and I messed up."
That transmission, captured on recorded communications, has become a central piece of evidence for both the NTSB investigation and the FAA's internal review.
The NTSB preliminary report also documented what the turret operator aboard the struck fire truck recalled hearing in the final moments.
"The turret operator in Truck 1 recalled hearing the words stop stop stop on the tower frequency radio, but he did not know who that transmission was intended for."
By the time anyone said "stop," the geometry of the collision was already locked in.
Investigators are also examining whether one of the controllers briefly stepped away from the console to answer a "crash phone," a dedicated emergency hotline, in the moments before the collision. The New York Post reported that this question is a live line of inquiry for the NTSB.
Two controllers were on duty in the tower at the time. NTSB Chair Jennifer Homendy confirmed that number represents the standard overnight staffing level at LaGuardia and at towers across the country. But investigators are also scrutinizing whether controller roles may have been improperly combined before midnight due to staffing shortages, effectively asking fewer people to do more jobs during a period when an active emergency was already stretching their attention.
The ASDE-X system exists for one reason: to prevent ground collisions at busy airports. It is supposed to track vehicles and aircraft on runways and taxiways and alert controllers when a conflict develops. On March 22, it did neither.
The FAA's own post-crash review of the ASDE-X data confirmed the system failure. The fire truck's missing transponder was one factor. But the system also failed to display all seven rescue vehicles operating on the airport surface, a gap that went beyond a single missing transponder.
The NTSB's preliminary findings make clear that the crash did not result from one isolated mistake. It emerged from a cascade of overlapping failures across human judgment, communication, and automated safety systems that were supposed to serve as backstops when human judgment faltered.
The collision has intensified scrutiny of the FAA's well-documented staffing crisis. The agency is currently short roughly 3,000 air traffic controllers nationwide. LaGuardia itself had 33 controllers assigned against a target of 37, a gap of more than ten percent at one of the busiest airports in the northeastern corridor.
Former federal crash investigator Alan Diehl framed the broader pressure plainly.
"In the best of times, air traffic controls and air traffic controllers are under a great deal of stress."
John Cox, CEO of Safety Operating Systems, said investigators will need to determine whether staffing levels or fatigue played a role. "The staffing issue and the controller's work schedule will certainly be something that they look at and only then can we determine if it's a staffing or fatigue issue," Cox told AP News.
The staffing shortage is not new. Controllers and their unions have warned for years that the workforce is stretched thin, that overtime is routine, and that the margin for error shrinks with every unfilled position. Government shutdowns have compounded the problem by disrupting training pipelines and forcing experienced controllers to absorb additional shifts.
The FAA's decision to pursue firings puts the agency in a difficult position. On one hand, the controller's own radio admission and the NTSB's factual findings point to a clearance that should never have been issued. On the other, the systemic failures surrounding that clearance raise the question of whether individual terminations address the actual problem or simply assign blame to the people closest to the disaster.
Authorities have not publicly confirmed the identities of the controllers facing termination. The NTSB's full investigation remains ongoing, and the board's final report will examine the complete chain of events, including systemic factors, before issuing formal probable cause findings and safety recommendations.
Investigators will need to determine whether the ASDE-X failures at LaGuardia reflect a localized maintenance issue or a broader vulnerability in the system's deployment at airports nationwide. They will also need to assess whether overnight staffing standards, set at two controllers for a facility handling the complexity of LaGuardia, are adequate for periods when simultaneous emergencies arise.
The FAA has not publicly detailed the administrative process for the proposed terminations, including whether the controllers will have the opportunity to appeal. Federal employees generally have civil service protections that allow them to contest firings, and the controllers' union can be expected to scrutinize whether the agency is scapegoating individuals for institutional failures.
The NTSB investigation will continue on a separate track. The board does not assign blame or determine liability. Its mandate is to establish probable cause and issue recommendations designed to prevent recurrence. Those recommendations, when they come, will likely address the ASDE-X system failures, transponder requirements for ground vehicles, and tower staffing standards.
Two pilots are dead because a fire truck was cleared onto a runway in the path of a landing jet. Every safety system that should have caught the error failed to catch it. Firing the controllers may satisfy the demand for accountability, but it will not fix the radars, fill the empty chairs in the tower, or bring back the margin of safety that vanished long before March 22.
