EASA AIRWORTHINESS DIRECTIVE

AD No.: 2014-0123

Date: 15 May 2014

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 EC 2042/2003 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 [EC 

2042/2003 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):

RB211-535E4 engines

TCDS Number: EASA.E.061

Foreign AD: Not applicable

Supersedure: This AD supersedes CAA UK AD 007-10-97 dated October 1997.

ATA 73

Engine – Low Pressure Fuel Filter to High Pressure Fuel Pump 

Tube Assembly – Replacement

Manufacturer(s): Rolls-Royce plc

Applicability: RB211-535E4-37, RB211-535E4-B-37 and RB211-535E4-C-37 engines, all 

serial numbers.

These engines are known to be installed on, but not limited to, Boeing 757 

series aeroplanes.

Reason: Fuel leaks from the Low Pressure (LP) fuel tube assembly located between the 

LP fuel filter and High Pressure (HP) fuel pump were reported in service. All the 

reported leaks were from the LP fuel tube assembly to Rolls-Royce Service 

Bulletin (SB) 73-C297 standard. Embodiment of the latter was required by CAA 

UK AD 007-10-97.

This condition, if not detected early enough or if not correctly managed, could 

lead to critical fuel unbalance or in-flight fuel starvation, possibly resulting in 

reduced control of the aeroplane. 

In order to address this potential unsafe condition, as a precautionary measure 

to mitigate the risk of critical fuel unbalance and in-flight fuel starvation, this AD 

supersedes CAA UK AD 007-10-97 and requires installation of a rigid fuel tube 

between the LP fuel filter and the HP fuel pump.

This AD also prohibits, after modification of an engine, (re-)installation of earlier 

LP fuel filter to HP fuel pump tube standards.
