What to do
Operators must identify if their GEnx-1B or GEnx-2B engines have the affected parts listed by part and serial numbers. They are required to remove and replace these parts with eligible replacements within 600 flight cycles after January 26, 2023, or before further flight if the engine is not currently in service. Installation of the affected parts is prohibited after the effective date of the directive.
Summary
The Federal Aviation Administration's Airworthiness Directive 2022-25-20 addresses certain General Electric Company GEnx-1B and GEnx-2B model turbofan engines. It targets high-pressure turbine stage 2 disks, forward seals, and stages 6-10 compressor rotor spools suspected to contain iron inclusions due to manufacturing defects. This directive aims to prevent potential engine failures and ensure continued airworthiness of affected engines.
What changed
This new airworthiness directive requires the replacement of affected high-pressure turbine stage 2 disks, forward seals, and stages 6-10 compressor rotor spools identified by specific part and serial numbers. It introduces mandatory removal and replacement of these parts within 600 flight cycles or before further flight if the engine is not in service. The directive also prohibits installation of the affected parts after the effective date.
Why it matters
This directive is critical for aviation professionals because the affected parts may have reduced material properties leading to premature fracture and uncontained engine failure. Operators and maintenance organizations must comply to prevent potential in-flight engine damage and ensure passenger safety. Compliance with this AD helps maintain regulatory adherence and avoid costly unplanned repairs or incidents.
