A plane collided with a vehicle on the ground at LaGuardia Airport, according to emergency officials, leading to multiple injuries.

The collision occurred around 11:30 p.m. Sunday from the Queens airport, FDNY officials said. Preliminary details of an investigation showed that an Air Canada plane was nearing the end of its landing procedure when it collided with what appeared to be a Port Authority vehicle, according to police.

Two sources familiar with the matter told NBC New York the plane was travelling about 30 mph at the time it collided with the vehicle. When taxiing, planes typically travel about 5 mph.

At least four people were injured, including two Port Authority police officers, who were taken to area hospitals. The two PAPD members — a sergeant and an officer — suffered broken bones in the collision, but were expected to recover.

There were four crew members on board the plane, along with 76 passengers, according to sources. The pilot and the co-pilot were badly injured, sources said, but no further information regarding their conditions was immediately available.

No passengers were believed to have been hurt.

City officials said to expect cancellations, road closures, traffic delays and a heavy FDNY presence near LaGuardia as a result of the incident, advising those on the roads to avoid the area.

What caused the collision was not immediately clear. An investigation is ongoing.

The collision occurred following an evening featuring bands of heavy rain across the New York City area. Video footage from the scene showed water on the tarmac as a result of the rain, but it wasn’t clear whether rain or weather conditions played a role in the incident.

Nor was it clear whether staffing at the airport played any sort of role in the collision. It comes after the Department of Homeland Security said more than 400 Transportation Security Administration workers had quit since a partial government shutdown that began on Feb. 14 left them working without pay. Air traffic control unions for years have also complained of a lack of staffing.
