According to the Federal Aviation Administration, some users of Pratt & Whitney’s geared turbofan engine will be required to undertake inspections within 30 days in order to prevent a part failure that could harm the aircraft.
A “rare condition” in powdered metal required 1,200 of the more than 3,000 engines constructed for the twin-engined Airbus A320neo between 2015 and 2021 to be removed and checked for microcracks, according to a July announcement by Pratt & Whitney parent RTX Corp.
According to the report, the FAA said it will mandate an ultrasonic check of the first- and second-stage high-pressure turbine discs within 30 days in an airworthiness regulation that was published on Friday. According to the organization, if the discs exhibit signs of damage, they must be changed before the next trip. The instruction goes into effect right away. Twenty engines on U.S.-registered aircraft and 202 engines globally are impacted by the FAA’s decision.
As a result of contaminated powder metal used in the manufacturing process, Pratt expects that 1,200 engines will need to be taken out of aircraft and evaluated during the next nine to twelve months.
The FAA claimed that its action came as a result of an additional investigation into the engine failure that forced an Airbus A320neo’s pilots to cancel a takeoff in December. Neither the agency nor Pratt would name the airline.
