Air Canada is at the center of renewed scrutiny after two LaGuardia Airport air traffic controllers reportedly left work early on the night an Air Canada Express jet collided with an airport fire truck, according to a source familiar with the investigation.
The revelation adds a significant new detail to the investigation into the March 22 crash, which claimed the lives of both pilots aboard Flight 8646. The aircraft had just landed at LaGuardia after a one-hour flight from Montreal when it struck the emergency vehicle crossing the taxiway.
Air Canada Crash Raises Critical Questions at LaGuardia
Flight 8646 was carrying 72 passengers and four crew members. Dozens of people were injured in the collision, which occurred as the fire truck responded to an incident elsewhere at the airport.
The two controllers were working in the airportâs control tower, the source said. Their departures were reportedly not limited to a matter of just a few minutes. The Federal Aviation Administration is now considering disciplinary action, and both controllers have been placed on leave, according to the source.
The FAA has not publicly confirmed the specific allegations or disclosed what disciplinary measures may be under consideration. In a statement, the agency said it was committed to accountability and would not compromise the safety or efficiency of the national airspace system.
FAA Review Intensifies as Controllers Remain on Leave
The reported departures are likely to draw attention because air traffic control staffing and runway coordination are central to airport safety. Controllers help manage aircraft movements, ground vehicles and emergency responses in complex, fast-moving environments.
However, investigators have not yet announced that the controllersâ early departure caused or directly contributed to the collision. The National Transportation Safety Board continues to examine the crash, including the actions of the flight crew, the fire truck and airport personnel.
The NTSBâs final report is not expected for approximately another six months. That report will include the agencyâs determination of probable cause and any contributing factors. Until then, investigators are expected to gather additional records, interview witnesses and analyze communications and airport procedures.
What the Investigation Could Reveal
The new information was first reported by The Wall Street Journal. Both the FAA and the National Air Traffic Controllers Association are parties to the NTSB investigation. That status generally limits what organizations can say publicly while an investigation remains active.
NATCA, the union representing air traffic controllers, did not confirm whether the employees were facing discipline. The union said it was âactively discussing these allegations with FAA leadershipâ and described those discussions as the appropriate forum for addressing the matter.
Transportation Secretary Sean Duffy also addressed the broader issue of accountability. He said the government would not tolerate fraud or actions that unfairly increase workloads for fellow controllers or disrupt the traveling public.
His comments come as federal officials face pressure to demonstrate that aviation safety rules are being enforced. Any disciplinary decision involving the LaGuardia controllers could become part of a larger examination of staffing, workplace conduct and oversight at major US airports.
Why the LaGuardia Collision Matters for Travelers
The collision has intensified concerns about how aircraft and emergency vehicles share airport surfaces. Runways and taxiways are carefully coordinated areas, and even a brief breakdown in communication can create serious danger.
For travelers, the case underscores the importance of layered safety procedures. Pilots, controllers, airport operations teams and emergency crews each have distinct responsibilities, but their actions must work together seamlessly.
Officials have not indicated that commercial air travel is broadly unsafe because of the incident. Still, the investigationâs findings could lead to changes in training, staffing policies or ground-movement procedures at LaGuardia and other airports.
For now, the families of the two pilots and the injured passengers continue to await a complete explanation. The NTSBâs final findings will be closely watched by aviation professionals, regulators and travelers seeking answers about what happened during the fatal Air Canada Express landing.
