Airworthiness Directive 2017-10-13
recurringAirworthiness Directives; Rolls-Royce plc Turbofan Engines
What this AD requires
We are superseding airworthiness directive (AD) 2015-17-19 for all Rolls-Royce plc (RR) RB211 Trent 768-60, 772-60, and 772B-60 turbofan engines. AD 2015-17-19 required inspection of the fan case low-pressure (LP) fuel tubes and associated clips and the fuel oil heat exchanger (FOHE) mounts and associated hardware. This AD requires an engine modification, which terminates the repetitive inspections. This AD was prompted by fractures on the LP fuel return tube at mid-span locations that were found with resulting fuel leaks. We are issuing this AD to correct the unsafe condition on these products.
Which aircraft AD 2017-10-13 applies to
Applies to engines if fitted with fuel tube, P/N FW53576, which was incorporated through RR production modification 73-F343 or which were modified in service in accordance with RR Service Bulletin (SB) RB.211-73-F343, Revision 4, dated May 26, 2011.
Whether AD 2017-10-13 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.
