Summary
We are superseding Emergency Airworthiness Directive (AD) 2017-21-51 for all Engine Alliance (EA) GP7200 series turbofan engines. AD 2017-21-51 was sent previously to all known U.S. owners and operators of GP7200 series turbofan engines. AD 2017-21-51 required visual inspections of all fan hubs for damage. This AD retains the same required actions as AD 2017-21-51 and clarifies the compliance requirements. This AD was prompted by the failure of a GP7200 fan hub. We are issuing this AD to address the unsafe condition on these products.
