United Boeing 777 Has Engine Failure, Causing Dulles Airport Brush Fire

Aircraft engine failures happen pretty frequently, and they’re not a huge deal. However, here’s an example of one that looked much worse than it was, given that it started a small fire on the ground.

United flight from Washington to Tokyo suffers engine failure

This incident happened on Saturday, December 13, 2025, and involves United Airlines flight UA803, operating from Washington Dulles (IAD) to Tokyo Haneda (HND). The flight was operated by a 27-year-old Boeing 777-200ER with the registration code N78004, and it had 290 people onboard, including 275 passengers and 15 crew members.

Shortly after taking off from runway 01C, at around 12:35PM, the crew declared a “mayday,” as they lost power in the left hand engine, and part of the engine cover also separated from the aircraft. The plane continued its climb to 5,000 feet, entered a holding pattern, and then dumped fuel, to lower its landing weight.

The plane then landed back at the airport around 45 minutes after the initial departure.

United flight UA803 returned to Washington Dulles

Following the incident, United released the following statement:

“Shortly after takeoff, United flight 803 returned to Washington Dulles and landed safely to address the loss of power in one engine. There were no reported injuries. We’ve temporarily closed a United Club lounge at Dulles to help assist our customers and work to get them to their destinations. United is grateful to our crews and to the teams at Washington Dulles for their quick work to help ensure the safety of everyone involved.”

Impressively, United managed to rebook all passengers for a flight on the same day, so the airline got a spare aircraft and crew pretty quickly (since the initial crew timed out). The replacement flight ended up taking off at 7:15PM, around seven hours behind schedule. It’s scheduled to land in Tokyo a little before 11PM, around six hours behind schedule. That’s not bad, all things considered!

This engine failure started a brush fire near the airport

I think the most interesting aspect of this story is that the plane’s engine failure somehow sparked a brush fire on the ground right by the airport. Obviously any sort of smoke coming from an airport is scary, given fears that the smoke may involve the aircraft as such.

It would appear that what happened is that a piece of the engine cover separated from the plane and caught fire, sparking a brush fire on the ground. Transportation Secretary Sean Duffy took to social media to write about this, and about how he was briefed on the situation.

That of course sounds a little dramatic for a basic engine failure, but given the optics of smoke coming from near an airport, I can understand why this was addressed.

Bottom line

A United Boeing 777 flying departing Washington for Tokyo had an engine failure shortly after takeoff. That’s not a huge story in and of itself, except for the fact that part of the engine cover separated from the aircraft, and it caused a brush fire on the ground.

All-in-all, United handled this situation really well, with no one being injured, and passengers getting to Tokyo with a delay of around six hours.

What do you make of this United engine failure with a twist?

No one cares about what goes on in Seppoland anyway.

Sounds familiar!! I was on this same flight in June and we had to return to Dulles after an hour of circling around West Virginia due to one engine sensor reading as very hot (the engine was hot-not a sensor malfunctioning.) Pretty hard landing with lots of fuel on board and firetrucks had to spray down the breaks after landing. We were sent to a lounge before boarding a new plane with a new crew...6 hours later.

Why are engines always called "left hand" and not just "left" ? And is that as you board, or as you are seated?

Hunh. I'm used to United having lots of maintenance delays and last minute equipment failures, but I always thought that once we actually took off we were in good shape. Has anyone who knows the industry scrutinized United's maintenance stats? My subjective experience, which is that their planes are broken a shocking amount of the time, is too small a dataset for a conclusion, but enough to make me ask the question. Are they maintaining their planes adequately?

It's not right to say that Aircraft engine failures happen "pretty frequently." It's pretty rare in my experience - non-existent in fact. Retired airlline pilot.
