Aircraft
changeThe incident aircraft, N772UA, is a Boeing 777 which flies for United Airlines. It was built in November 1994 and given to United Airlines in September 1995.[4] At first, the aircraft was a part of a test to approve its entry to fly commercially.[4]
Investigation
changeAs of July 25, 2021, the National Transportation Safety Board (NTSB) is looking into the incident. Debris was collected. The NTSB found that two blades on the engine were broken and the damage done to be the same as metal fatigue.[5][6]
Notes
change- ↑ The airliner was a Boeing 777-200 model; Boeing assigns a unique code for each company that buys one of its airliners, which is applied as an infix to the model number at the time the aircraft is built, hence "777-222" designates a 777-200 built for United Airlines (customer code 22).
