Is AD 2011-4831 a recurring Airworthiness Directive?

No — AD 2011-4831 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2011-4831 apply to?

AD 2011-4831 applies to Rolls-Royce — models RB211-Trent 768, RB211-Trent 772, RB211-Trent 772B, RB211. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

We are rescinding an existing airworthiness directive (AD) for the products listed above. The existing AD, AD 98-09-27, resulted from aircraft certification testing which revealed that stresses on the thrust reverser hinge were higher than had been anticipated during engine certification, and the United Kingdom Civil Aviation Authority, issuing AD 008-03-97. Since we issued AD 98-09-27, we discovered that its requirements were duplicated in airplane-level AD 2001-09-14, issued by the FAA Transport Airplane Directorate. We proposed to rescind the engine-level AD.

Whether AD 2011-4831 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 2011-4831 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.
