Preliminary NTSB Investigation Into United Flight 328 Reveals Fan Blade Damage

On February 20, 2021, United Airlines Flight 328 took off from Denver International Airport. The Boeing 777-200 operated was scheduled to land at Honolulu International Airport. Shortly after takeoff, the aircraft experienced a right engine failure. The plane landed safely at Denver International Airport, with no injuries or loss of life.

The National Transportation Safety Board (NTSB) on Monday provided an update on its investigation into United Airlines flight 328, revealing that the inlet and cowling separated from the Pratt & Whitney PW4000 turbofan aircraft engine, and that two of the engine’s fan blades were fractured. 

The current probe is being carried out by the NTSB along with the Federal Aviation Administration, United Airlines, Boeing, Pratt & Whitney, the Air Line Pilots Association and the Independent Brotherhood of Teamsters.

On Sunday, FAA Administrator Steve Dickson revealed that the agency will order “immediate or stepped-up” inspections of the Pratt & Whitney PW4000 fan blades.

​After Dickson’s announcement, United Airlines said it would be immediately removing 24 Boeing 777 airplanes from its fleet that use the Pratt & Whitney PW4000.

​On Sunday, Boeing also issued a statement addressing the incident.

Also on Monday, Egyptair announced that it would be grounding four of its Boeing 777s in response to Boeing’s investigation.

The latest incident comes after Boeing has struggled to repair its reputation after the Boeing 737 MAX 8 in March 2019 was grounded worldwide after 346 people died in two crashes: Lion Air Flight 610 and Ethiopian Airlines Flight 302. 

The aircraft’s new flight control system, the Maneuvering Characteristics Augmentation System (MCAS), was found to be the cause behind both deadly accidents. The MCAS, designed to be a safety feature, is supposed to evaluate sensor data and push the plane’s nose down to keep it from stalling in the event that the nose of the plane is too high.
