one-timeAirworthiness Directives; Rolls-Royce Deutschland (RRD) (Formerly Rolls-Royce, plc) TAY 611-8, TAY 620-15, TAY 650-15, and TAY 651-54 Series Turbofan Engines; Correction
What this AD requires
This document makes a correction to Airworthiness Directive (AD) 2004-05-22. That AD applies to certain RRD TAY 611-8, TAY 620-15, TAY 650-15, and TAY 651-54 series turbofan engines with ice-impact panels installed in the low pressure (LP) compressor case. We published AD 2004-05-22 in the Federal Register on March 10, 2004, (69 FR 11305). The AD number in the Amendatory Language is incorrect. This document corrects that AD number. In all other respects, the original document remains the same.
Which aircraft AD 04-6577 applies to
certain
Whether AD 04-6577 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:
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.
