EASA AIRWORTHINESS DIRECTIVE

CANCELLATION NOTICE

AD No.: 2010-0132-CN

Date: 14 October 2013

Note: This Airworthiness Directive (AD) Cancellation Notice (CN) 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.

Design Approval Holder’s Name:

AIRBUS

Type/Model designation(s):

A330 aeroplanes

TCDS Number: EASA A.004

Foreign AD: Not applicable

Cancellation: This Notice cancels EASA AD 2010-0132R1 dated 10 June 2013.

ATA 28 CANCELLED: Fuel – Main Fuel Pump System Water Scavenge 

System – Deactivation

Manufacturer(s): Airbus (formerly Airbus Industrie)

Applicability: Airbus A330-243, A330-243F, A330-341, A330-342 and A330-343 aeroplanes, 

all manufacturer serial numbers on which Airbus modification 56966H16199 

has been embodied in production or Airbus Service Bulletin A330-28-3105 has 

been embodied in service, except those on which Airbus modification 200801 

has been embodied in production.

Reason: During an in-service event, the flight crew of a Trent 700 powered A330 

aeroplane reported a temporary Engine Pressure Ratio (EPR) shortfall on 

engine 2 during the take-off phase of the flight. The ENG STALL warning was 

set. The flight crew followed the standard procedures which included reducing 

throttle to idle. The engine recovered and provided the demanded thrust level 

for the remainder of the flight. 

Data analysis confirmed a temporary fuel flow restriction and subsequent 

recovery, and indicated that also engine 1 experienced a temporary fuel flow 

restriction shortly after the initial event on engine 2, again followed by a full 

recovery. The engine 1 EPR shortfall was insufficient to trigger any associated 

warning and was only noted through analysis of the flight data. No flight crew 

action was necessary to recover normal performance on this engine. The 

remainder of the flight was uneventful. 

Based on industry-wide experience, the investigation of the event focused on 

the possibility for ice to temporarily restrict the fuel flow. While no direct fuel 

system fault was identified, the operation of the water scavenge system (WSS)

at Rib 3 was considered to have been a contributory factor.

Prompted by these findings, EASA issued Emergency AD 2010-0042-E to

require deactivation of the automatic Standby Fuel Pump Scavenge System

and to prohibit dispatch of an aeroplane with one main fuel pump inoperative.

Subsequently, EASA issued AD 2010-0132 which superseded EASA AD 2010-

0042-E, retaining its requirements, to expand the applicability to the newly 

certified model A330-243F. EASA AD 2010-0132 was later revised to remove 

the dispatch restriction with one main fuel pump inoperative.

Since EASA AD 2010-0132R1 was issued, extensive fuel system icing risk 

investigations testing was conducted by Airbus and Rolls-Royce, the results of 

which confirmed that the Rib 3 WSS operation does not induce any risk of fuel 

feed system (including the engine) blockage by ice accreted on the pipework 

and/or pump inlets. In addition, it was demonstrated that the risk of fuel flow 

restriction by ice at the Fuel Oil Heat Exchanger (FOHE) interface on 

aeroplanes equipped with Trent 700 engines is now adequately addressed by

introduction of a re-designed FOHE, more tolerant to the release of ice 

(modification 200218). The modified FOHE (incorporating enhanced anti-icing 

and de-icing performance) is required to be installed on all Trent 700 engines 

through EASA AD 2009-0257.

Previously, the operation of the WSS at Rib 3 was no longer considered as a 

main contributory factor on ice build-up and subsequent release of ice into the 

fuel system. Based on the latest information, the deactivation of the automatic 

Standby Fuel Pump Scavenge System is no longer required.

For the reasons described above, this Notice cancels EASA AD 2010-0132R1.
