Airworthiness Directive 2018-17704

Airworthiness Directives; Rolls-Royce Corporation Engines

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Rolls-Royce Corporation (RRC) AE 2100D2A and AE 2100D3 model turboprop engines and AE 3007A2 model turbofan engines. This AD was prompted by the possibility of a low-cycle fatigue failure on certain turbine wheels. This AD requires removing the affected turbine wheels at the next engine shop visit or before reaching the new reduced life limit, whichever occurs first, and replacing them with parts eligible for installation. We are issuing this AD to address the unsafe condition on these products.

Serial-conditional — narrows to serials MW65898–MW65898, MW68310–MW68310, MW65895–MW65895, MW65896–MW65896, MW65900–MW65900, MW65901–MW65901, MW65903–MW65903, MW68305–MW68305, MW68306–MW68306, MW68307–MW68307, MW68312–MW68312, MW68314–MW68314, MW68316–MW68316, MW68318–MW68318, MW68319–MW68319, MW65894–MW65894, MW68303–MW68303, MW68315–MW68315.
Part-conditional — 23089692, 23088906.

AE 3007A2 is a turbofan engine (not turboprop); it and the AE 2100 models are included only when the specified 1st-stage turbine wheel with the listed serial number is installed: AE 2100D2A gas generator turbine wheel P/N 23089692; AE 2100D3 gas generator turbine wheel P/N 23088906; AE 3007A2 high-pressure turbine (HPT) wheel P/N 23088906.

Whether AD 2018-17704 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 2018-17704 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.
