Airworthiness Directives; Rolls-Royce RB211 Series Turbofan Engines; Correction

What this AD requires

This document makes a correction to Airworthiness Directive (AD) 2003-12-15 that applies to Rolls-Royce (RR) plc RB211-535E4-37, RB211-535E4-B-37, and RB211-535E4-B-75 series turbofan engines that was published in the Federal Register on June 25, 2003. A service bulletin was incorrectly identified by revision number and revision date in the Compliance section, paragraph (a) and the Optional Terminating Action section, paragraph (f). This document corrects these items. In all other respects, the original document remains the same.

Which aircraft AD 03-21412 applies to

Whether AD 03-21412 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 03-21412 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.
