Air Canada Express jet collides with fire truck at LaGuardia, injuring two officers
An Air Canada Express Bombardier CRJ-900 collided with a fire truck on Runway 4 at LaGuardia Airport around 11:40 p.m. ET Sunday, March 22, 2026, causing the FAA to issue a full ground stop halting all arrivals and departures. The aircraft, operating Flight 8646 from Montreal-Trudeau with over 100 passengers, sustained heavy nose damage and tilted upward after impact. At least two Port Authority officers on the fire truck were critically injured, and the airport remained closed as of early March 23 with potential reopening not before 1800 GMT.
The ground stop diverted inbound flights to JFK and Newark or forced returns to origin airports. Travelers with bookings to or from LaGuardia today face cancellations and multi-hour delays as the wreckage blocks taxiways — the 2023 JetBlue snowplow collision at the same airport took four hours to clear, suggesting a similar recovery timeline if the runway reopens by late afternoon.
A taxiing collision between an Air Canada Express regional jet and an airport fire truck shut down all operations at LaGuardia Airport late Sunday night, stranding passengers and triggering a cascade of diversions across the New York metro area.
Flight 8646, a Bombardier CRJ-900 arriving from Montreal, struck the fire truck on Runway 4 while taxiing after landing in rainy conditions. Photos from the scene show the aircraft’s nose heavily damaged and the fuselage tilted sharply upward — the kind of structural impact that grounds an aircraft for weeks.
The FAA responded with a full ground stop, halting all LaGuardia arrivals and departures. Inbound flights diverted to JFK and Newark or returned to their origin airports. The Port Authority has not confirmed when the runway will reopen, but internal communications suggest 1800 GMT March 23 as the earliest possible clearance time.
At least two Port Authority officers riding in the fire truck sustained critical injuries and were transported to local hospitals. The status of the 100+ passengers aboard the aircraft remains unclear as of early Monday morning, though initial reports suggest no passenger injuries.
What the ground stop means for flights today
LaGuardia handles roughly 1,100 flights daily, with peak morning departures between 0600 and 0900 local time. The ground stop — still active as of 0500 ET Monday — has already forced dozens of cancellations and diversions, and the ripple effect will extend well into the afternoon even if the runway reopens by midday.
The 2023 JetBlue incident at LaGuardia offers a precedent: when an A321 struck a snowplow on Taxiway B, the airport cleared the wreckage in four hours and resumed limited operations by evening. That collision involved less structural damage than Sunday’s fire truck impact, suggesting a longer recovery timeline this time.
Flights already airborne when the ground stop was issued diverted to JFK and Newark, adding 30–60 minutes to passenger travel times. Departures scheduled for late Sunday were either canceled outright or held at gates until the FAA lifts restrictions. The Times of India confirmed the ground stop remains in effect with no official end time announced.
| Metric | Impact | Comparison |
|---|---|---|
| Ground stop duration | 6+ hours (ongoing) | 2023 JetBlue: 90 min |
| Estimated cancellations | 100+ flights | Typical daily ops: 1,100 |
| Runway clearance ETA | 1800 GMT (1 p.m. ET) | 2023 precedent: 4 hours |
| Injuries | 2 critical (fire truck crew) | 2023 incident: 0 |
How this collision compares to past LaGuardia incidents
Ground vehicle collisions at major airports are rare but not unprecedented. The January 2023 JetBlue snowplow strike at LaGuardia caused a 90-minute ground stop and cleared within four hours — but that incident involved a taxiway, not an active runway, and resulted in no injuries.
Sunday’s collision is more severe: the fire truck was on Runway 4, the aircraft sustained visible structural damage, and at least two people were critically injured. The FAA’s decision to issue a full ground stop rather than a partial closure signals the extent of the disruption — emergency response vehicles, wreckage, and investigative teams all occupy the same space needed for normal operations.
The CRJ-900 involved in the collision is a regional jet operated by Air Canada Express under contract with Air Canada. The aircraft seats 76 passengers in a standard configuration, though the exact load on Flight 8646 has not been confirmed. Regional jets like the CRJ-900 are workhorses on short-haul routes between US and Canadian cities, and Montreal-LaGuardia is a high-frequency corridor with multiple daily departures.
What to do if your flight is affected
The ground stop creates immediate stakes for anyone with a LaGuardia booking in the next 12–24 hours — cancellations and diversions are already confirmed, and the backlog will take hours to clear even after the runway reopens.
- Check your flight status now: Use FlightAware or your airline’s app to confirm whether your flight is canceled, delayed, or diverted. Do not rely on email notifications — they lag real-time updates by 30+ minutes.
- Rebook proactively: If your flight is canceled, call your airline’s rebooking hotline immediately. Air Canada: 1-888-247-2262. Delta: 1-800-221-1212. American: 1-800-433-7300. Request same-day rebooking to JFK or Newark at no charge.
- Monitor the FAA NOTAM system: The official source for runway status is the FAA NOTAM search portal. Search for “KLGA” to see real-time updates on the ground stop.
- Document expenses: If you’re stranded overnight due to a cancellation, keep receipts for meals and hotels. US DOT rules do not require airlines to reimburse these costs for weather or operational disruptions, but some carriers offer goodwill vouchers.
Watch: The Port Authority’s official statement on runway clearance timing — if Runway 4 reopens before 1800 GMT, expect 1–2 hour delays. If it extends past that window, cancellations will exceed 100 flights and recovery will stretch into Tuesday morning.
Will Air Canada compensate passengers on Flight 8646?
US DOT rules require refunds for cancellations or delays exceeding three hours, but do not mandate cash compensation for operational disruptions like ground collisions. Air Canada may offer meal vouchers, hotel accommodations, or rebooking at no charge, but passengers should not expect EU261-style payouts.
How long does it typically take to clear a runway after a ground collision?
The 2023 JetBlue snowplow incident at LaGuardia cleared in four hours, but that involved less structural damage and no critical injuries. Sunday’s collision is more complex — expect 6–12 hours from impact to full operations, assuming no additional complications during wreckage removal.
Should I avoid booking LaGuardia flights this week?
If the runway reopens by Monday afternoon, normal operations should resume by Tuesday. However, if you have flexibility, JFK and Newark offer more capacity and redundancy — a single-runway closure at LaGuardia has outsized impact compared to multi-runway hubs.
