NTSB Probes LaGuardia Runway Collision That Killed Two Air Canada Pilots as Runway Remains Closed and Controller Workload Questioned
An Air Canada Express CRJ‑900 (Flight 8646) landing at LaGuardia around 11:45 p.m. on March 22 collided with a Port Authority Aircraft Rescue and Firefighting truck that was crossing Runway 4 to respond to a separate odor incident, killing the pilot and first officer—both Canada‑based—and injuring about 40 passengers, crew and two firefighters, most of whom have since been released from hospitals. The NTSB has recovered the flight data and cockpit voice recorders, kept the runway closed for days while wreckage was cleared, and is probing tower communications and logs, overnight controller workload and staffing practices, and why surface‑detection systems and the truck’s lack of a transponder did not prevent the collision.
📌 Key Facts
- At about 11:45 p.m. ET on March 22, 2026, Air Canada Express Flight 8646 (a Bombardier CRJ‑900 operated by Jazz Aviation from Montreal) struck a Port Authority Aircraft Rescue and Firefighting (ARFF) truck on Runway 4 at LaGuardia; both the pilot and copilot were killed.
- The two deceased pilots were identified as Capt. Antoine Forrest (Forest) and First Officer Mackenzie Gunther. About 72 passengers and four crew were aboard; roughly 39–41 passengers/crew and a small number of ARFF personnel were injured and taken to hospitals — most have since been released while several remained hospitalized in later reports.
- The ARFF truck was on the runway responding to a separate United flight that had reported a concerning odor; tower recordings indicate the vehicle was initially cleared to cross before the collision.
- Live air‑traffic‑control audio captured repeated orders of 'Stop, stop' to 'Truck 1' and a controller later saying 'I messed up.' The NTSB reported only two controllers were on duty, with at least one performing multiple roles, and has flagged workload, staffing and overnight tower practices as central issues in the investigation.
- Investigators said the lead firefighting vehicle did not have a transponder and LaGuardia’s ASDE‑X surface‑monitoring system did not generate an alert because merging movements prevented creation of a 'high confidence' track.
- Runway‑camera video shows the CRJ’s nose sheared off and the fire truck flipping multiple times in a rain‑soaked landing; crews later towed the damaged airliner off the runway and righted the truck, which has been moved to a secure location for evidence.
- The NTSB recovered the cockpit voice recorder and flight data recorder (by cutting a hole in the fuselage as needed) and transported them to its Washington lab; investigators are examining tower actions, communications and procedures and say the impacted runway will likely remain closed for days while debris and wreckage are processed.
- The FAA issued a ground stop, LaGuardia was closed after the crash and later reopened with limited operations and significant delays; the Port Authority has said it aims to have the blocked runway reopened by no later than the following Friday pending inspections. Federal and local officials have expressed condolences and are cooperating with the NTSB probe.
📊 Relevant Data
The number of air traffic controllers in the U.S. has declined by about 6% in the last decade, while there has been a 10% increase in air traffic movements.
In 2024, the FAA recorded 1,758 runway incursions across the United States, averaging just under five incidents per day.
After LaGuardia crash, focus turns to ATC staffing and near misses — Aerospace Global News
As of September 2024, over 40% of air traffic control facilities were understaffed, falling short of the FAA's 85% staffing goal for terminal air control facilities.
Records show there have been at least 11 midair collisions and five ground or runway collisions related to air traffic control in recent years, amid concerns over controller fatigue and workload.
Years of data show US air traffic control system 'straining at the seams' — InvestigateTV
The ASDE-X system, installed at 35 U.S. airports, provides alerts for potential runway conflicts but may not generate warnings if it cannot create a 'high confidence' track, such as in cases of merging movements or vehicles without transponders.

An air traffic controller was juggling extra roles during the LaGuardia plane crash
New information:
- NTSB Chair Jennifer Homendy said there were only two controllers in the LaGuardia tower at the time of the crash and that at least one was performing several controller roles.
- Homendy specified that the controller‑in‑charge was also acting as the clearance‑delivery controller and that investigators have conflicting information about whether that controller or the local controller was also serving as ground controller.
- Homendy framed the issue as a systemic midnight‑shift staffing practice—often two controllers covering several positions—and directly questioned whether that practice makes sense at a high‑traffic airport like LaGuardia.
- She reiterated longstanding NTSB concerns about fatigue and workload on the midnight shift, while noting there is currently no evidence fatigue contributed to this specific crash.
- NTSB investigator Doug Brazy provided a more detailed timeline from the cockpit voice recorder’s final three minutes, including that an unknown airport vehicle’s radio call was “stepped on” by overlapping transmissions before firefighters requested and received clearance to cross the runway in response to fumes from a United Airlines plane.

NTSB flags ‘conflicting information’ in LaGuardia tower, unclear who handled ground-control duties
New information:
- NTSB Chair Jennifer Homendy says investigators have found 'conflicting information' in LaGuardia control-tower logs, including discrepancies in dates and times.
- It remains unclear who was performing the ground-controller role before the collision, with conflicting accounts indicating either the controller-in-charge or the local controller; roles may have been combined under standard overnight procedures.
- Preliminary cockpit voice recorder summary: the fire truck requested permission to cross Runway 4 about 25 seconds before the recording ended; clearance was given at about 20 seconds remaining, a stop order was issued at 9 seconds, the aircraft’s gear sound appears at 8 seconds, control shifted to the captain at 6 seconds, and another stop order came at 4 seconds.
- The lead firefighting vehicle did not have a transponder, which limited what controllers and the airport surface detection equipment could see.
- NTSB says the ASDE-X surface monitoring system did not generate an alert because the close proximity of vehicles merging near the runway prevented creation of a 'high confidence' track.
