Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Tay 611-8, Tay 611-8C, Tay 620-15, Tay 650-15, and Tay 651-54 Turbofan Engines

What this AD requires

The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) Tay 611-8, Tay 620- 15, Tay 650-15, and Tay 651-54 turbofan engines. That AD currently requires initial and repetitive visual inspections of all ice-impact panels and fillers in the low pressure (LP) compressor case for certain conditions and replacing, as necessary, any or all panels. This AD requires the same actions, provides terminating action to those repetitive actions, and adds the Tay 611-8C turbofan engine to the applicability. This AD results from RRD introducing new LP compressor case ice-impact panels with additional retention features to these Tay turbofan engines. We are issuing this AD to prevent release of ice- impact panels due to improper bonding that can result in loss of thrust in both engines.

Repetitive inspection. Re-inspect every 3000 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Serial-conditional — narrows to serials ?–85078.
Part-conditional — TAY-72-1326.

Applies to Tay 611-8, 620-15, 650-15, and 651-54 engines that have one or more ice-impact panels installed in the LP compressor case conforming to RRD Service Bulletin No. TAY-72-1326 standard; and to Tay 611-8C engines with serial number below SN 85078.

Whether AD 2007-26-19 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 2007-26-19 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.
