Is AD 2003-13-12 a recurring Airworthiness Directive?

No — AD 2003-13-12 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2003-13-12 apply to?

AD 2003-13-12 applies to Rolls-Royce. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Rolls-Royce plc RB211-22B Series Turbofan Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to Rolls-Royce plc (RR) RB211-22B series turbofan engines with intermediate pressure (IP) compressor stage 6 to 7 rotor shaft assembly part number (P/N) UL37094 installed. This amendment requires removal from service of IP compressor stage 6 to 7 rotor shaft assemblies P/N UL37094 before reaching newly reduced life limits. This amendment is prompted by the discovery of corrosion during inspection and analysis of IP compressor stage 6 to 7 rotor shaft assemblies returned from the field. The actions specified by this AD are intended to prevent corrosion-induced cracking of the IP compressor stage 6 to 7 rotor shaft assembly, resulting in an uncontained engine failure and damage to the airplane.

MakesRolls-Royce

Part-conditional — UL37094.

Specific Rolls-Royce engine model not stated in retrieved applicability text (three-shaft architecture implied by 'IP compressor' terminology); addresses IP compressor stage 6 to 7 rotor shaft assembly, P/N UL37094, life-limited to 13,500 cycles-since-new (or 12,980 CSN if Rolls-Royce service bulletin 72-8700 incorporated).

Whether AD 2003-13-12 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 2003-13-12 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.
