C. REASON (1) History The THALES Angle Of Attack (AOA) sensor Part Number (PN) C16291AA, basic standard fitted on SA and LR aircraft, experience an ageing issue of the heating element, which means that after a given number of Flight Hours (FH), the vane of the AOA sensor may not be able to de-ice properly in severe icing conditions. (2) Objective/Action For aircraft on which one or more THALES PN C16291AA AOA sensors are installed, this Inspection Service Bulletin mandates the periodic a functional test of the heating of the AOA sensor and replacing the AOA sensor if the test fails. (3) Advantages Accomplishment of this Inspection Service Bulletin will allow the detection of any defective THALES PN C16291AA AOA sensors, up to the embodiment of the terminating action. The accomplishment of the Service Bulletin No. A340-34-4234 (Install THALES AOA sensors PN C16291AB) cancels this inspection requirement and cancels the Maintenance Planning Document (MPD) task 341300-02-1. (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". D. DESCRIPTION NOTE: To accomplish the repair of the affected AOA sensor(s) you have two possibilities : - either you replace them as per AMM Task 34-11-19-000-801 and AMM Task 34-11-19-400-801 in accordance with SUBTASK 344215-960-001 001 OPTION 1 - Replace the Affected AOA Sensor(s) , - or you replace them as per Service Bulletin in accordance with SUBTASK 344215-960-002 001 OPTION 2 - Replace the Affected AOA Sensors by Another PN as Terminating Action

. To accomplish this Service Bulletin it is necessary to : Task 344215-832-801-001: Inspection (1) Do a Detailed Inspection of the Three AOA Sensors (FINs 3FP1, 3FP2 and 3FP3). Task 344215-833-801-001: Repair (1) OPTION 1 - Replace the Affected AOA Sensor(s) (2) OPTION 2 - Replace the Affected AOA Sensors by Another PN as Terminating DATE: May 28/08 SERVICE BULLETIN No.: A340-34-4215 REVISION No.: 03 - Jul 27/15 Page: 4 5

# @A340 SERVICE BULLETIN
Action E. COMPLIANCE (1) Classification MANDATORY: Service Bulletin must be accomplished. (2) Accomplishment Timescale This Service Bulletin has been classified Mandatory by the issue of an Airworthiness Directive (AD) published by the European Safety Agency (EASA). Tha AD must be used as the reference document for the mandated accomplishment timescale. Accomplishment of this Inspection Service Bulletin must be done before 17,000 Flight Hours (FH), since the aircraft first flight. For the aircraft which were added in the effectivity of this Service Bulletin at revision 01 and which have exceeded this threshold, a grace period of six months has been agreed from the issue of this Inspection Service Bulletin at revision 01 for the first inspection. Repeat the inspection of each THALES AOA sensor PN C16291AA at interval not exceeding 3,800 FH. NOTE: The accomplishment of the Service Bulletin No. A340-34-4234 as terminating action cancels this inspection. F. APPROVAL The technical content of this document is approved under EASA Design Organisation Approval No. EASA.21J.031. If an aircraft listed in the effectivity has a modification or repair embodied that is not of AIRBUS origin, and which affects the content of this Service Bulletin, the operator is responsible for obtaining approval by its airworthiness authority for any adaptation necessary before incorporation of the Service Bulletin. G. MANPOWER The manpower estimates given in this Service Bulletin are based on the direct labor cost to do the work. These estimates assume that the work will be done by experienced personnel, and may need to be revised upwards to suit operator’s circumstances. The estimates do not include the time to prepare, plan or inspect the work. Manufacture and procurement of parts and tools, drying times for paints, sealants, etc., and general administration work are also not included.
