Airworthiness Directives; General Electric Company Turbofan Engines

FAA / Federal Register · 2022-16011

The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) CF34-8C and CF34-8E model turbofan engines. This proposed AD was prompted by a report of a crack found on the low-pressure turbine (LPT) stage 5 disk at the forward arm area. This proposed AD would require the removal of the affected LPT stage 5 disk and replacement with a part eligible for installation. The FAA is proposing this AD to address the unsafe condition on these products.
