EASA AD CF-2023-30
Engine — High Pressure Turbine 1st / 2nd Stage Disks - Suspected Material Defect
Canadian Airworthiness Directive CF-2023-30 addresses suspected material defects in the high pressure turbine (HPT) 1st and 2nd stage disks of Pratt & Whitney Canada PW307A and PW307D engines. This directive follows an uncontained HPT disk failure event in an Airbus A321-231 powered by a related engine model. It mandates removal and replacement of specific affected HPT disks to prevent potential engine damage and ensure continued airworthiness.
