Boeing 787 Dreamliner A United Airlines en route to Munich declared a Mayday emergency shortly after takeoff from Washington Dulles International Airport, prompting immediate action from the flight crew and air traffic control.
Engine Failure Triggers Emergency
Flight UA108, operated by a Boeing 787-8 Dreamliner, experienced a left engine failure at an altitude of approximately 5,000 feet within minutes of departure. The wide-body aircraft was scheduled for a transatlantic flight to Munich, Germany, with a full complement of passengers and crew onboard.
Upon detecting the engine malfunction, the pilots declared a Mayday and initiated standard emergency protocols to ensure passenger safety.
Emergency Procedures and Safe Landing
To reduce the aircraft’s landing weight, the crew climbed to 6,000 feet and entered a holding pattern northwest of Washington D.C., where they conducted fuel dumping for nearly 2 hours and 38 minutes. Close coordination with air traffic control (ATC) ensured safe separation from other aircraft during this extended maneuver.
The pilots then requested an Instrument Landing System (ILS) approach to Runway 19C at Dulles. The aircraft landed safely, but due to the engine failure, it was unable to taxi under its own power and was towed from the runway by ground crews.
No Injuries, But Aircraft Grounded
There were no injuries reported among passengers or crew. United Airlines confirmed that the aircraft remains grounded pending a comprehensive investigation by the airline’s maintenance division and U.S. aviation authorities.

Context: Boeing 787 Dreamliner Reliability and Market Watch
This incident draws attention to ongoing safety scrutiny of the Boeing 787 Dreamliner, a flagship aircraft in Boeing’s wide-body fleet. The Boeing 787 has seen multiple reliability concerns in recent years, particularly surrounding engine components and electrical systems.
The emergency involving UA108 follows a recent Air India Dreamliner incident, also involving an engine malfunction shortly after takeoff, raising new questions about long-haul aircraft safety protocols.
