Airworthiness Directives; Rolls-Royce Corporation Turbofan Engines

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Rolls-Royce Corporation (RRC) AE 3007A and AE 3007C model turbofan engines. This AD was prompted by an updated analysis that lowered the life limit of fan wheels installed on the affected engines. This AD requires removal of the affected fan wheel at new, lower life limits. We are issuing this AD to address the unsafe condition on these products.

Part-conditional — 23061670.

Applies only to engines with fan wheel P/N 23061670 installed.

Whether AD 2017-27778 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 2017-27778 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.
