Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Tay 620-15 Engines

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Tay 620-15 turbofan engines. This AD was prompted by reports of low-pressure compressor (LPC) fan blade retention lug failures. This AD requires reviewing the engine maintenance records and replacing the LPC fan blade with a part eligible for installation if the dry-film lubricant (DFL) treatment limit is exceeded. We are issuing this AD to address the unsafe condition on these products.

Part-conditional — JR30649, JR31702, JR31983, JR33863, JR33864.

Applies only when low-pressure compressor (LPC) fan blades with the listed part numbers are installed.

Whether AD 2018-17-13 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.

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.
