Airworthiness Directives; Rolls-Royce plc RB211 Trent 768-60, Trent 772-60, and Trent 772B-60 Series Turbofan Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to Rolls-Royce plc RB211 Trent 768-60, Trent 772-60, and Trent 772B-60 series turbofan engines having common nozzle assembly part number (P/N) FK16544 or FK16558. This action requires initial and repetitive visual inspections of the inner and outer skins of the common nozzle assembly and specifies allowable limits for cracks, loose rivets, and missing rivets. This action also requires repair if the common nozzle assembly damage exceeds allowable limits. This amendment is prompted by two reports of in-flight inner skin detachment. The actions specified in this AD are intended to detect cracks, loose rivets, and missing rivets, which could result in inner skin detachment, release of common nozzle assembly debris from the engine, and possible damage to the airplane control surfaces.

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

ModelsRB211
Part-conditional — FK16544, FK16558.

Applies to common nozzle assembly P/N FK16544 or FK16558; requires visual inspection for cracks, loose rivets, and missing rivets within 500 flight hours of the effective date, with repetitive inspections every 500 flight hours for assemblies exceeding 1,500 cycles-since-new, per Rolls-Royce Mandatory Service Bulletin RB.211-78-C931, Revision 1, dated June 13, 2000. Specific RB211 variant not stated in the extracted applicability text.

Whether AD 2000-24-24 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 2000-24-24 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.
