MODIFICATIONS
MODIFICATION CLASSIFICATION MAJOR None MINOR 49228S16346 58555S30640 NOTE : As per EASA IR 21, a minor change is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics affecting the airworthiness of the product. All other changes are major changes.
REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES The design of the heater of THALES Angle Of Attack (AOA) sensor PN C16291AA suffers from an ageing issue, which affects the heating efficiency of the vane The loss of AOA heating efficiency appears over a number of flight hours which depends on the operational life of the AOA sensors, especially the number of flight cycles (vibration modes), power ON/OFF sequences, handling, etc... accumulated by the vane.
At system level , consequences are a possible los s of windshear and/or al pha protection and/or spurious reversion into Alternate law.
Airbus recommends operators to perform a recurrent functional test of the AOA heating on affected AOA sensor PN C16291AA, as per Inspection Service Bulletin No. A340-34-4215 (refer to OIT ref.
SE999.0036/08/BB dated on 2nd May 2008).
In order to increase the reliability of AOA sensors and to reduce the probability of vane heating failures, the vane of THALES AOA probe PN C16291AA has been redesigned.
This Service Bulletin is published to inform all operators of A340 aircraft of the issue of THALES AVIONICS Service Bulletin No. C16291A-34-009.
This Service Bulletin proposes replacement of the three Thales AOA sensors PN 45150320 or PNC16291AA by three new THALES AOA sensors PN C16291AB.
