Airworthiness Directive 2016-04-13
one-timeAirworthiness Directives; Rolls-Royce plc Turbofan Engines
What this AD requires
We are superseding airworthiness directive (AD) 2015-04-03 that applies to certain Rolls-Royce plc (RR) RB211 Trent 768-60, 772- 60, and 772B-60 turbofan engines. AD 2015-04-03 required inspection of the sealing sleeve on the high-pressure/intermediate-pressure (HP/IP) turbine support internal oil feed tube and removal of those sealing sleeves affected by AD 2015-04-03. This AD requires removal of either the affected sealing sleeve only or both the affected sealing sleeve and the oil feed tube. This AD was prompted by fractures of the HP/IP turbine support internal oil feed tube. We are issuing this AD to prevent failure of the HP/IP turbine support internal oil feed tube, uncontained engine failure, and damage to the airplane.
Which aircraft AD 2016-04-13 applies to
Applies to all serial numbers of the listed engines EXCEPT those with Modification 72-H754 applied in production, or modified per RR SB RB.211-72-H754 (Supplement Revision 1 dated July 29, 2015, or initial issue dated Oct 1, 2014), or with sealing sleeve P/N FW15003 marked 102013, 112013, or 102013L installed.
Whether AD 2016-04-13 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.
