What to do
Operators must remove the affected LPTR stage 4 disks before they exceed 3,000 cycles since new and the LPTR stage 6 disks before 5,000 cycles since new. Replacement parts must be eligible for installation, meaning they do not have the specified part and serial numbers. Requests for alternative methods of compliance can be submitted to the FAA's ECO Branch following established procedures.
Summary
The Federal Aviation Administration's Airworthiness Directive 2022-19-01 addresses certain General Electric Company GEnx-2B67/P model turbofan engines. It targets specific low-pressure turbine rotor stage 4 and stage 6 disks identified by part and serial numbers due to a detected iron inclusion that may reduce their fatigue life. This directive mandates the removal and replacement of these affected disks to ensure continued airworthiness.
What changed
This new airworthiness directive introduces mandatory removal and replacement requirements for specific LPTR stage 4 and stage 6 disks on GE GEnx-2B67/P engines. It identifies affected parts by part and serial numbers and sets compliance thresholds based on cycles since new. The directive also provides definitions for parts eligible for installation and outlines procedures for alternative methods of compliance.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk that could lead to premature disk fracture and uncontained engine debris release, potentially causing engine and aircraft damage. Operators and maintenance organizations must track affected parts and ensure timely replacement to maintain regulatory compliance and flight safety. Failure to comply could result in unsafe operating conditions and regulatory penalties.
