Airworthiness Directives; Engine Alliance Turbofan Engines

What this AD requires

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.

Whether AD 2017-23-03 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 2017-23-03 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
