EASA AIRWORTHINESS DIRECTIVE

AD No.: 2015-0105R1

Date: 18 August 2015

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with 

Regulation (EC) No 216/2008 on behalf of the European Community, its Member States and 

of the European third countries that participate in the activities of EASA under Article 66 of that 

Regulation.

This AD is issued in accordance with EU 748/2012, Part 21.A.3B. In accordance with EU 1321/2014 Annex I, Part M.A.301, the 

continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may operate 

an aircraft to which an AD applies, except in accordance with the requirements of that AD, unless otherwise specified by the Agency

[EU 1321/2014 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemption].

Design Approval Holder’s Name:

ROLLS-ROYCE plc

Type/Model designation(s):

RB211 Trent 700 engines

TCDS Number: EASA.E.042

Foreign AD: Not applicable

Revision: This AD revises EASA AD 2015-0105 dated 10 June 2015, which superseded

EASA AD 2014-0168 dated 16 July 2014.

ATA 72

Engine – High / Intermediate Pressure Turbine Bearing Support

Oil Feed Tube Sealing Sleeve – Inspection / Replacement 

Manufacturer(s): Rolls-Royce plc (RR)

Applicability: RB211 Trent 768-60, 772-60, 772B-60 and 772C-60 engines, all serial 

numbers (s/n), except those that have Modification (Mod) 72-H754 applied in 

production, or have been modified in-service by RR Service Bulletin (SB)

RB.211-72-H754.

These engines are known to be installed on, but not limited to, Airbus A330 

aeroplanes.

Reason: Several occurrences were reported of high oil consumption on Trent 700 

engines, caused by fracture of the High/Intermediate Pressure (HP/IP) turbine 

support internal oil feed tube Part Number (P/N) FW46689. The oil feed tube 

threaded end adaptor and sealing sleeve P/N FW15003 are designed to form

a sliding joint which, if restrained, can compress the oil feed tube during 

thermal contraction of the turbine casing at the end of the flight cycle. On each 

subsequent flight, the thermal growth and contraction of the turbine casing 

relative to the oil tube, during the heating and cooling phases of the flight 

cycle, apply a load cycle to the tube, which may lead to low cycle fatigue 

fracture.

This condition, if not detected and corrected, could lead to fire and 

overheating of the turbine discs and, consequently, an uncontained engine 

failure, possibly resulting in damage to the aeroplane and injury to occupants 

and/or persons on the ground.

Investigation of the affected oil feed tube sealing sleeve P/N FW15003 found 

that one supplier of this part had manufactured some sealing sleeves with the

internal diameter below the drawing minimum, which can cause binding at the

sliding joint. Investigation of the supply history identified a population of 

engines which have potentially been fitted with an affected sleeve during 

manufacture, or during Module 51 rework (check, repair or higher level work 

scope) between 1 July 2009 and 31 October 2013, as identified in RR NonModification Service Bulletin (NMSB) RB.211-72-AH673.

Prompted by these findings, EASA issued AD 2014-0168 to require a 

one-time inspection of the affected engines and removal from service of all 

affected P/N FW15003 oil feed tube sealing sleeves.

Since that AD was issued, investigation results confirmed that most

occurrences were attributable to the non-conforming sealing sleeve. However, 

a more recent event of high oil consumption was reported, on an engine 

which did not have an affected sealing sleeve fitted. Investigation established 

that some oil feed adaptors P/N FW49471 have been manufactured with an

outer diameter larger than the drawing maximum.

This condition can restrain the sliding joint in a similar way as an undersized

sealing sleeve, possibly resulting in the same unsafe condition addressed by 

EASA AD 2014-0168.

Consequently, EASA issued AD 2015-0105, retaining the requirements of

EASA AD 2014-0168, which was superseded, to require a one-time inspection 

of more oil feed sealing sleeves, and, depending on findings, replacement of 

the sealing sleeves and tubes.

Since that AD was issued, it was determined that for replacement of parts, RR 

NMSB RB.211-72-AJ035 only made reference to a modification (new P/N 

parts in accordance with RR SB RB.211-72-H754) of the engine, which 

implied that the same P/N parts could no longer be installed, thereby 

contradicting the AD, which does not require a modification. RR have revised

the NMSB for clarification. In addition, it was found that EASA AD 2015-0105 

inadvertently made reference to ‘external’ parts (tubes and adaptors).

For the reasons described above, this AD is revised to confirm that engine 

modification is not required, and to remove the references to ‘external’ parts.

This AD also excludes post-Mod/SB 72-H754 engines from the Applicability, 

since the affected oil feed tube sealing sleeve P/N FW15003 is not part of that 

engine configuration.

Effective Date: Revision 1: 18 August 2015

Original issue: 24 June 2015

Required Action(s) 

and Compliance

Time(s):

Required as indicated, unless accomplished previously:

Note: Where, in this AD, reference is made to an RR Mod, SB or NMSB with 

an ‘A’ (Alert) in the number, it should be recognised that an earlier or later 

revision may not have that ‘A’. This kind of change does not effectively alter 

the publication references for the purpose of this AD.

Re-statement of the requirements of EASA AD 2014-0168:

(1) For engines s/n up to 42330 inclusive, except s/n 42310, 42311, 42312, 

42314 to 42317 inclusive, 42321 to 42327 inclusive, and 42329:

Within 6 months after 01 August 2014 [the effective date of EASA AD

2014-0168], inspect the P/N FW15003 oil feed tube sealing sleeve and, if 

it is determined that the oil feed tube sealing sleeve was manufactured by 

supplier A, as defined in RR NMSB RB211-72-AH673, and does not have 

the marking 102013, 112013 or 102013L, take a replicast and replace the 

affected oil feed tube sealing sleeve with a serviceable oil feed tube 

sealing sleeve in accordance with the instructions of RR NMSB 

RB211-72-AH673.

(2) Within 30 days after taking the replicast, as required by paragraph (1) of 

this AD, send the replicast to RR in accordance with the instructions of RR 

NMSB RB211-72-AH673.

(3) For all engines: From 01 August 2014 [the effective date of EASA AD 

2014-0168], it is allowed to install on any engine an oil feed tube sealing 

sleeve P/N FW15003 manufactured by supplier A (as defined in RR 

NMSB RB211-72-AH673), provided the part has the marking 102013, 

112013 or 102013L.

New requirements of this AD:

(4) For engines s/n up to 42330 inclusive: Within 1 600 flight cycles or 24 

months, whichever occurs first after 24 June 2015 [the effective date of the 

original issue of this AD], inspect each P/N FW15003 oil feed sealing 

sleeve to identify the marking 102013, 112013 or 102013L in accordance 

with the instructions of RR NMSB RB.211-72-AJ035.

A review of engine maintenance records is acceptable to make the 

determination as specified in this paragraph, provided those records can 

be relied upon for that purpose, and the markings on the P/N FW15003 oil 

feed sealing sleeve can be conclusively identified from that review.

(5) If, during the inspection as required by paragraph (4) of this AD, a sealing 

sleeve P/N FW15003 is found without marking 102013, 112013 or 

102013L, before next flight or (if inspected in shop) before release to 

service of the engine, as applicable, replace the affected parts with 

serviceable parts in accordance with the instructions of RR NMSB 

RB.211-72-AJ035.

(6) For all engines: From 24 June 2015 [the effective date of the original issue 

of this AD], it is allowed to install on any engine an oil feed tube sealing 

sleeve P/N FW15003, provided the part has the marking 102013, 112013 

or 102013L.
