Contributing to the fan blade failure was the inadequate inspection of the blades, which failed to identify low-level indications of cracking, and the insufficient frequency of the manufacturer\u2019s inspection intervals, which permitted the low-level crack indications to propagate undetected and ultimately resulted in the fatigue failure. Contributing to the severity of the engine damage following the fan blade failure was the design and testing of the engine inlet, which failed to ensure that the inlet could adequately dissipate the energy of, and therefore limit further damage from, an in-flight fan blade out event. Contributing to the severity of the engine fire was the failure of the \u201cK\u201d flange following the fan blade out, which allowed hot ignition gases to enter the nacelle and imparted damage to several components that fed flammable fluids to the nacelle, which allowed the fire to propagate past the undercowl area and into the thrust reversers, where it could not be extinguished.","registration":"N772UA","state":"CO","summary":"Incident on February 20, 2021 at Broomfield, CO: no injuries, minor damage.","type":"INC"}],"num_engines":2,"other_names":"","plain_english":"N772UA is a Boeing 777-222, a fixed-wing airplane with more than one motor with turbofan engines, built in 1995.
