What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2017-09-06 for all General Electric Company (GE) GEnx-1B and GEnx-2B model turbofan engines. AD 2017-09-06 required updating electronic engine control (EEC) full authority digital electronic control (FADEC) software on GEnx-1B and GEnx-2B turbofan engines and replacing a certain fan hub frame assembly part installed on GEnx-2B turbofan engines. This AD requires updating EEC software on GEnx-1B and GEnx-2B engines and replacing a certain fan hub frame assembly part installed on GEnx-2B engines. This AD was prompted by the development of a design change by GE to remove the unsafe condition. The FAA is issuing this AD to address the unsafe condition on these products.

Whether AD 2020-13-04 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 2020-13-04 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.
