Key Takeaways
• On June 12, 2025, United Airlines UA1736 had a right engine failure after takeoff from Denver International Airport.
• The Boeing 777-222ER safely landed with 354 people despite worsening weather and a one-engine rollback emergency.
• The FAA is investigating the engine malfunction; no injuries reported and no immediate policy changes announced.
On June 12, 2025, United Airlines Flight UA1736, operated by a Boeing 777-222ER, faced a serious engine problem just after taking off from Denver International Airport. The flight, which was headed to Kahului, Hawaii, had 354 people on board, including both passengers and crew. The right engine, known as engine number two, suddenly lost power and could not provide the thrust needed for flight. This situation, called a “rollback,” meant the plane had to rely on just one engine while carrying more than 121,000 pounds of fuel.
The pilots acted quickly, declaring an emergency and staying close to Denver International Airport. Despite worsening weather, including strong winds and windshear (a sudden change in wind speed or direction), the crew managed to land the plane safely on runway 26. Emergency teams checked the aircraft on the taxiway, and everyone on board was confirmed safe. No injuries were reported.
This event has drawn attention from aviation experts, passengers, and regulatory authorities. It highlights the importance of strong safety procedures and quick thinking by flight crews. Here’s a detailed look at what happened, why it matters, and what it could mean for travelers, airlines, and the future of aviation safety.
What Happened: The Emergency Landing
Who: United Airlines Flight UA1736, a Boeing 777-222ER (registration N219UA), with 354 passengers and crew
What: Critical engine failure (engine number two lost power)
When: June 12, 2025
Where: Shortly after takeoff from Denver International Airport, Colorado
Why: Engine malfunction—exact cause under investigation
How: Pilots declared an emergency, stayed near the airport, and landed safely despite bad weather
The incident began soon after takeoff. The flight crew noticed that the right engine was not working properly. When an engine “rolls back,” it means it stops producing enough power for safe flight. With only one engine working, the pilots had to act fast. They told air traffic control about the emergency and prepared to return to Denver International Airport.
At the same time, the weather was getting worse. Wind gusts and windshear made flying and landing more difficult. In fact, all other arrivals at the airport were put on hold because of the dangerous conditions. Still, the pilots managed to bring the plane in for a safe landing using a visual approach, which means they relied on what they could see rather than only on instruments.
Once the plane was on the ground, emergency crews checked it for any further problems. Passengers and crew were able to leave the plane safely after the inspection.
Step-by-Step: How the Crew Handled the Emergency
The actions of the United Airlines crew followed a clear, step-by-step process designed for emergencies like this:
- Engine Failure Detected: The pilots noticed the right engine was not working as it should.
- Emergency Declared: The crew immediately told air traffic control about the problem.
- Checklist Procedures: The pilots followed emergency checklists, which are step-by-step guides for handling engine failures.
- Weather Coordination: The crew worked with air traffic controllers to plan the safest way to land, taking into account the bad weather.
- Visual Approach and Landing: The pilots landed the plane using a visual approach, relying on their training and what they could see.
- Post-Landing Inspection: Emergency teams checked the plane on the taxiway to make sure there were no further dangers.
- Passenger Disembarkation: Everyone left the plane safely after the inspection.
This careful and professional response is being praised by aviation experts as an example of good training and teamwork.

Why This Matters: Safety, Operations, and Policy
Passenger Safety
The most important outcome is that all passengers and crew were unharmed. United Airlines is known for providing support to passengers after such events, which can include rebooking on other flights and offering counseling or compensation if needed.
Operational Impact
- The emergency landing and bad weather caused temporary disruption at Denver International Airport. Arrivals were paused, which led to delays for other flights.
- Incidents like this often lead to a closer look at airline maintenance practices and emergency procedures, especially for long-haul flights leaving from high-altitude airports like Denver.
Technical Review
- United Airlines will likely increase inspections of similar engine models on its Boeing 777 fleet.
- The airline may also review and update its emergency response protocols for flights departing from airports with challenging conditions.
Expert Analysis: What the Incident Shows
Aviation Safety Experts
Experts in aviation safety have pointed out that the crew’s response was a textbook example of how to handle a serious emergency. The pilots’ ability to stay calm, follow procedures, and work as a team made a big difference. This is especially important on twin-engine, long-haul aircraft like the Boeing 777, where losing one engine can be very serious.
Passenger Perspective
For passengers, the experience was likely frightening. However, reports suggest that United Airlines kept passengers informed and safe throughout the ordeal. The airline’s crisis response and communication protocols will likely be reviewed to see if they can be improved even further.
Regulatory Perspective
The FAA’s investigation will focus on several key areas:
- What caused the engine to fail?
- Were the maintenance records up to date?
- Did the crew follow all emergency procedures correctly?
Depending on what the investigation finds, there could be changes to how similar aircraft are maintained or operated in the future.
Background: Boeing 777 and Denver International Airport
Boeing 777 Engine Incidents
The Boeing 777 is known for its strong safety record. However, there have been rare cases of engine failures in the past. When these happen, they often lead to regulatory reviews and, in some cases, temporary groundings of certain engine models. This is done to make sure all planes are safe before they fly again.
Denver International Airport
Denver International Airport is one of the highest major airports in the United States 🇺🇸. High-altitude airports present special challenges for pilots, especially when planes are fully loaded with passengers, cargo, and fuel for long flights. The thinner air at high altitudes means engines have to work harder, and takeoff and landing require extra care.
Looking Ahead: What Happens Next?
Investigation Results
The FAA and United Airlines will continue to investigate what caused the engine failure. Once they know more, they will release their findings to the public. If they find a problem that could affect other planes, they may issue technical directives or require extra maintenance checks for similar aircraft.
Possible Policy Changes
If the investigation finds a bigger issue, the FAA could issue what’s called an Airworthiness Directive. This is an official order that requires airlines to fix or check certain parts of their planes before they can fly again. These directives are posted on the FAA’s official website, where anyone can read them.
Communication with Passengers
United Airlines is expected to keep affected passengers and the public updated as more information becomes available. The airline’s customer service team can be reached at 1-800-UNITED-1 (1-800-864-8331) for questions or concerns.
Implications for Stakeholders
For Passengers
- Safety remains the top priority. Incidents like this show that airlines and airports are prepared for emergencies.
