Airworthiness Directives; General Electric Company (GE) GE90-76B Model Turbofan Engines

Lokale automatische vertaling · Oorspronkelijke brontaal

Samenvatting

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to General Electric Company (GE) GE90-76B model turbofan engines. This proposed AD would require reduced life limits for certain rotating components installed in GE90-76B engines. This proposal is prompted by the results of a refined life analysis performed by the manufacturer which revealed minimum calculated low cycle fatigue lives lower than the published low cycle fatigue retirement lives for certain rotating components installed in the GE90-76B engines. If not corrected, this condition could result in a low cycle fatigue failure of a rotating component and possibly an uncontained engine failure.
