Airworthiness Directives; Rolls-Royce plc Turbofan Engines

What this AD requires

We are superseding airworthiness directive (AD) 2017-22-13 for certain Rolls-Royce plc (RR) RB211-Trent 900 turbofan engine models. AD 2017-22-13 required an inspection of the drains mast and the replacement or repair of the drains mast if a crack is found. This AD retains this requirement, but adds repetitive inspections and expands the population of affected RR RB211-Trent 900 turbofan engine models. This AD was prompted by RR in-service findings that indicated a need to include part number (P/N) FW29847 drains mast and additional RR RB211- Trent 900 turbofan engines to the affected population. We are issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect every 24 months. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Which aircraft AD 2019-05-02 applies to

MakesRolls-Royce Plc
ModelsRB211-Trent 970-84, RB211-Trent 972-84, Trent 900
Part-conditional — KH31996, FW29847.

Applies only to engines with a drains mast, P/N KH31996 or FW29847, installed.

Whether AD 2019-05-02 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 2019-05-02 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.
