Is AD 2003-17-15 a recurring Airworthiness Directive?

No — AD 2003-17-15 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2003-17-15 apply to?

AD 2003-17-15 applies to Rolls-Royce — models RB211-535E4, RB211-535E4-B, RB211. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

This amendment supersedes an existing airworthiness directive (AD) that applies to Rolls-Royce plc. (RR) models RB211-535E4-37, RB211- 535E4-B-37, and RB211-535E4-B-75 turbofan engines, with certain part number (P/N) low pressure (LP) turbine stage 2 discs installed. That AD currently requires establishing new reduced LP turbine stage 2 disc cyclic limits. That AD also requires removing from service affected discs that already exceed the new reduced cyclic limits, and removing other affected discs before exceeding their cyclic limits, using a drawdown schedule. This amendment requires changing certain cyclic limits, changing the effective date of certain disc cyclic lives, and would allow intermix of Flight Plan A and Flight Plan B intermix calculations. This amendment is prompted by a reassessment of the thermal and stress data from recent operational experience and comments received from operators on the current AD. We are issuing this AD to prevent LP turbine stage 2 disc failure, which could result in uncontained engine failure and possible loss of the airplane.

Applicability provision truncated in this excerpt ('each engine identified in the preceding applicability provision'); named engines (RB211-535E4, RB211-535E4-B) appear in LP turbine stage 2 disc cyclic (CSN) life-limit tables, differentiated by Flight Plan A vs. Flight Plan B operation, to prevent LP turbine stage 2 disc failure.

Whether AD 2003-17-15 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 2003-17-15 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.
