Applicability*9
This AD applies to Rolls-Royce plc (RR) RB211 Trent 553-61, RB211 Trent 553A2-61, RB211 Trent 556-61, RB211 Trent 556A2-61, RB211 Trent 556B-61, RB211 Trent 556B2-61, RB211 Trent 560-61, and RB211 Trent 560A2-61 turbofan engines that have any of the following fuel tube part numbers installed: FW57605, FW17689, FW57604, FK30710, FW57578, or FK30713.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
(1) Inspect the LP fuel tubes, clips, and fuel/oil heat exchanger (FOHE) mounts of the LP fuel system of engines that are on wing within 1,600 flight hours after February 24, 2012, or before the next flight after the effective date of this AD, whichever occurs later. Use the Accomplishment Instructions, paragraph 3.A, of RR Alert Non-Modification Service Bulletin (NMSB) RB.211-73-AG948, Revision 3, dated September 9, 2016, to do the inspection. (2) At intervals not to exceed 5,000 engine flight hours (EFH), reinspect the LP fuel tubes, clips, and FOHE mounts using the Accomplishment Instructions, paragraph 3.A or 3.B, of RR Alert NMSB RB.211-73-AG948, Revision 3, dated September 9, 2016. (3) If the LP fuel system fails the inspections required by paragraphs (g)(1) and (2) of this AD, replace the part(s) that failed the inspection with hardware eligible for installation before further flight. (4) At any shop visit after the effective date of this AD, inspect the LP fuel system using the Accomplishment Instructions, paragraph 3.B, of RR Alert NMSB RB.211-73-AG948, Revision 3, dated September 9, 2016.
Unsafe condition
This AD was prompted by reports of wear found between the securing clips and the low-pressure (LP) fuel tube outer surface, which reduces the fuel tube wall thickness, leading to fracture of the fuel tube and consequent fuel leakage. We are issuing this AD to prevent engine fuel leaks, which could result in engine damage and damage to the airplane.
Affected ADs
This AD supersedes AD 2013-05-18, Amendment 39-17390 (78 FR 17297, March 21, 2013).

TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
