Timeline: Safety board releases final minutes of Air Canada collision at LaGuardia

Mar 24, 2026 | 3:07 PM

NEW YORK — The U.S. National Transportation Safety Board has released flight data and radio transmissions of the final three minutes of the fatal Air Canada flight at New York’s LaGuardia Airport Sunday night. The information indicates that a fire truck had been cleared to cross a runway at the busy New York airport only 20 seconds before it collided with the jet.

The crash killed the two pilots and sent more than 40 to hospital. The safety board said it will convene a group on Wednesday to review the cockpit voice recorder and produce a written transcript.

Also of note, officials said the runway warning system, known as the ASDE-X — Airport Surface Detection Equipment — had failed to generate an alert. That system allows air traffic controllers to track surface movement of aircraft and vehicles, but it didn’t work as intended because the fire truck — described as Truck 1 in the radio transmission data — did not have a transponder.

Below is a summary of the events captured by the cockpit recording, as related by the safety board. They said the information is subject to change. The timecodes reflect the minutes before the fatal collision.

3:07 — Controller instructed aircraft to contact the LaGuardia control tower.
