Airworthiness Directives; Rolls-Royce plc Turbofan Engines

What this AD requires

We are adopting a new airworthiness directive (AD) for Rolls- Royce plc (RR) RB211-535E4-37, -535E4-B-37, -535E4-C-37, RB211Trent 768-60, 772-60, and 772B-60 turbofan engines. This AD requires removal of certain high-pressure (HP) and intermediate-pressure (IP) turbine discs before their accumulated cyclic lives have reached the revised limits. This AD was prompted by a report of an HP disc contaminated with a steel inclusion. We are issuing this AD to prevent failure of the HP or IP turbine disc, uncontained engine failure, and damage to the airplane.

Applies only to engines with the specific turbine disc part number and serial number combinations listed in Table 1 to paragraph (c) of this AD (new reduced cyclic life limits for HP/IP turbine discs): RB211-535E4 series discs P/N UL39767 (S/N LDRCZ19900, LDRCZ19903, LDRCZ19904); RB211 Trent 768/772/772B discs P/N FK26893 (S/N LDRCZ19901, LDRCZ20081, LDRCZ20082, LDRCZ20084, LDRCZ20088, LDRCZ20089, LDRCZ20090, LDRCZ20093, LDRCZ20094, LDRCZ20097, LDRCZ20099, LDRCZ20100) or P/N FK20795 or FW53118 (S/N LDREB12176 through LDREB12180).

Whether AD 2013-23-17 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 2013-23-17 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.
