Ground Collision At Denver International Forces Emergency Response After United Jet Strikes De-Icing Vehicle

Federal investigators have launched a probe into a serious ground collision at Denver International Airport (DEN) that left an airport contractor hospitalized and a Nashville-bound Boeing 737 significantly damaged. The incident occurred during the height of a severe winter storm on Friday morning, March 6, when a United Airlines aircraft made contact with a de-icing truck, causing the specialized vehicle to flip onto its side.

United Airlines Flight 605, a Boeing 737-800 carrying 122 passengers and six crew members, was preparing for departure to Nashville International Airport (BNA) when the accident unfolded at approximately 8:30 a.m. local time. The aircraft was operating on a central de-icing pad, a high-traffic zone designed for pre-flight fluid application, where heavy snow and limited visibility were reported at the time of the impact.

Emergency Response and Injuries

The collision centered on the aircraft's right wing, which struck the cab of the de-icing truck with enough force to overturn the vehicle. Denver Fire Department crews and paramedics were dispatched immediately to the tarmac. While no injuries were reported among the passengers or flight crew, the operator of the de-icing truck, an employee of a contracted ground-service provider, was trapped in the wreckage before being extracted.

Eyewitnesses on the aircraft described a "jolting impact" followed by the sight of emergency responders attending to the injured worker. The contractor was reportedly stabilized on a backboard and rushed to a local hospital. As of this morning, the specific condition of the worker has not been publicly updated.

Passenger Evacuation and Airline Response

Following the collision, the Boeing 737 was declared non-airworthy due to visible damage to its wingtip and winglet. Passengers were forced to deplane via mobile air stairs onto the snowy tarmac before being transported by bus back to the terminal.

United Airlines confirmed the details of the event in a statement issued shortly after the crash:

“A de-icing truck made contact with a United aircraft in Denver on Friday morning, leading to an employee of the de-icing contractor being transported to the hospital. Customers deplaned via air stairs and were bused to the terminal, and we arranged for a different aircraft to take customers to their destination.”

Travelers received automated notifications via the United mobile app shortly after the impact, which categorized the delay under maintenance:

“Your flight is departing late because we are addressing a maintenance issue on your plane. Your safety is our priotity and we're sorry for the inconvenience (returned to gate).”

FAA Investigation Underway

The Federal Aviation Administration (FAA) has officially opened an investigation to determine the sequence of events. A critical focus of the inquiry involves the movement of the aircraft relative to the de-icing truck. According to the FAA, the incident occurred in an area of the airfield where air traffic control does not have direct oversight of ground movements, placing the responsibility for separation on the flight crew and ground coordinators.

Preliminary reports suggest the aircraft may have begun to taxi before the de-icing procedure was fully completed. A passenger on the flight recounted the moments leading up to the impact to local media:

"It was just a little shocking because we were going through the de-icing process and we started moving. There were some loud noises and the plane kind of jolted."

The following data reflects the scheduled versus actual operation of the affected flight following the ground collision and subsequent aircraft swap.

*Duration includes extended taxi times due to ongoing winter weather operations at DEN.

Weather Impact on Hub Operations

The collision occurred during a "First Alert Weather Day" in Colorado, which saw up to five inches of snow accumulate across the Denver metro area. The storm caused a ripple effect across the airport’s network, resulting in over 1,200 flight delays and 150 cancellations on Friday alone. De-icing operations are standard under such conditions, but the intensity of the storm has raised questions regarding ground safety protocols during peak-demand periods.

The damaged aircraft, a Boeing 737-800 registered as N27213, remains out of service at Denver for structural inspections and repairs.
