EAST HARTFORD, CONN., February 23, 2021 - The U.S. Federal Aviation Administration has issued an Airworthiness Directive requiring inspection of fan blades on the Pratt & Whitney PW4000-112' engines prior to their return to service.
The process requires the shipment of fan blades to Pratt & Whitney where Thermal Acoustic Imaging (TAI) inspection will be used to confirm airworthiness. The inspection is performed by Pratt & Whitney's FAA-authorized repair station.
Pratt & Whitney powers approximately 125 Boeing 777 aircraft with its PW4000-112' engine. The directive applies only to the PW4000-112' model, and the fan blades that are unique to this engine type.
Pratt & Whitney is coordinating all actions with Boeing, airline operators and regulators. The safe operation of the fleet is our top priority.
Pratt & Whitney commends the flight crew operating United Airlines flight 328 for their professionalism.
Further investigative updates regarding United Airlines flight 328 will be at the discretion of the NTSB.
