SUMMARY REV 00 Aug 04/20 A350-31-P039 Page 3
(1) History T wo events of engine in-flight shut down were experienced. Affected operators reported that before the event, liquid was spilled on the Integrated Control Panel (ICP) ENG START and Electronic Centralized Aircraft Monitoring (ECAM) Control Panel (ECP) (135VM). Investigations showed a susceptibility of the ICP internal connectors to liquid. This susceptibility can result in erroneous output signals. The first mitigation step consisted in installing a removal protective cover on the ICP-ENG START and ECP (135VM) in order to protect the unit against liquid spillage.
(2) Objective/Action This Service Bulletin mandates to remove protective cover (installed by Service Bulletin No. A350-31-P038 (Modification No. 116010L48610)) and to install a new ICP- ENG START and ECP (135VM) equipped with improvements (gasket, liquid collector, drains) to avoid liquid ingress inside the electronic part of the unit.
This Service Bulletin is published to advise all operators of A350 aircraft of the issue of LEONARDO S P A AIRBORNE & SPACE (A4582) VSB 727-7212-03-31-001 and VSB 727- 7312-XX-31-001 which modifies the ICPs.
(3) Advantages Accomplishment of this Service Bulletin installs a new ICP more robust to liquid ingress.
(4) Operational/Maintenance Consequences The Operational/Maintenance Consequences of this Service Bulletin are covered by the update of the affected publications detailed in "PLANNING INFORMATION".
This Service Bulletin cancels Operations Engineering Bulletin No. 9 issue 3 and Airplane Flight Manual (AFM) T emporary Revision (TR) 124.
This Modification Service Bulletin concerns the airworthiness limitations of Airworthiness Limitation Section (ALS) Part 4 which is introduced within the Aircraft (A/C) maintenance program under the operator responsibility. Please download the relevant ALS Variation on AirbusWorld.
This Service Bulletin has an impact on flight operations documentation; refer to AirbusWorld to consult the available Modification Operational Impact (MOI).

CONF ALL B. CONCURRENT REQUIREMENTS Accomplishment of this Service Bulletin requires the prior or simultaneous accomplishment of this/these Service Bulletin(s):
Service Bulletin(s) Modification(s) Ref. SB A350-31-P038 116010L48610 NOTE: Service Bulletin No. A350-31-P038 (INDICATING/RECORDING SYSTEMS -
INTEGRATED CONTROL PANELS (ICP) - DEFINE AND INSTALL REMOVABLE COVER ON ICP ENG START AND ECAM CONTROL PANEL) is a concurrent requirement if MOD No.
116010L48610 has not been embodied before delivery.
C. REASON
(1) History T wo events of engine in-flight shut down were experienced. Affected operators reported that before the event, liquid was spilled on the Integrated Control Panel (ICP) ENG START and Electronic Centralized Aircraft Monitoring (ECAM) Control Panel (ECP) (135VM). Investigations showed a susceptibility of the ICP internal connectors to liquid. This susceptibility can result in erroneous output signals. The first mitigation step consisted in installing a removal protective cover on the ICP-ENG START and ECP (135VM) in order to protect the unit against liquid spillage.
(2) Objective/Action This Service Bulletin mandates to remove protective cover (installed by Service Bulletin No. A350-31-P038 (Modification No. 116010L48610)) and to install a new ICP- ENG START and ECP (135VM) equipped with improvements (gasket, liquid collector, drains) to avoid liquid ingress inside the electronic part of the unit.
This Service Bulletin is published to advise all operators of A350 aircraft of the issue of LEONARDO S P A AIRBORNE & SPACE (A4582) VSB 727-7212-03-31-001 and VSB 727- 7312-XX-31-001 which modifies the ICPs.
(3) Advantages Accomplishment of this Service Bulletin installs a new ICP more robust to liquid ingress.
(4) Operational/Maintenance Consequences The Operational/Maintenance Consequences of this Service Bulletin are covered by the update of the affected publications detailed in "PLANNING INFORMATION".
This Service Bulletin cancels Operations Engineering Bulletin No. 9 issue 3 and Airplane Flight Manual (AFM) T emporary Revision (TR) 124.
This Modification Service Bulletin concerns the airworthiness limitations of Airworthiness Limitation Section (ALS) Part 4 which is introduced within the Aircraft (A/C) maintenance program under the operator responsibility. Please download the relevant ALS Variation on AirbusWorld.
This Service Bulletin has an impact on flight operations documentation; refer to AirbusWorld to consult the available Modification Operational Impact (MOI).
