### TITLE: FUSELAGE - REAR FUSELAGE - INSPECTION OF LONGITUDINAL DOUBLER AT VTP ATTACHMENT CUT OUT **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES During long life structure tests on the A340-600, damage was found in the upper shell structure between FR80 and FR86. This damage occurred between 58341 and 72891 simulated Flight Cycles (FC). Under consideration of the Design Service Goal (DSG) of 16600 FC for A340-600 aircraft, no action is required. Nevertheless, due to the higher DSG of 20000 FC and different design (e.g. doubler thickness) for A340-300 aircraft, this damage is considered relevant for these models. This Service Bulletin has been issued to inform the operator to do an eddy current high frequency inspection of the upper shell structure between FR80 and FR86. The accomplishment of this Service Bulletin will allow early detection of cracks in order to avoid possible crack propagation and will ensure the structural integrity of the upper shell structure between FR80 and FR86. Airbus strongly recommended to perform the modification at the next convenient opportunity after the first inspection to avoid large repairs especially in case of crack finding. Accomplishment of modification Service Bulletin 53-4165 cancels the inspection required by this inspection Service Bulletin up to the DSG of 20000 FC for A340-300.

D. DESCRIPTION To accomplish this Service Bulletin it is necessary to : **CONF 001 Task 534174-832-848-001: INSPECTION (1) Do a special detailed inspection of the Area A FR80, B FR84 and C FR86 for A340-300 WV020 thru WV026 and WV028 thru WV029 **CONF 002 Task 534174-832-848-001: INSPECTION (1) Do a special detailed inspection of the Area A FR80, B FR84 and C FR86 for A340-300 WV050 thru WV052. **CONF ALL E. COMPLIANCE (1) Classification MANDATORY: Service Bulletin must be accomplished. (2) Accomplishment Timescale This Service Bulletin has been classified Mandatory. It is expected that an Airworthiness Directive (AD) published by the European Aviation Safety Agency (EASA) will be issued to confirm this classification. It is anticipated that the AD will confirm the (thresholds and/or intervals and/or date) given above but reference should be made to the AD for confirmation of the mandated accomplishment timescale. NOTE: Two sets of thresholds/intervals (Short Range, Threshold/Interval (SR) and Long Range, Threshold/Interval (LR)) have been established. Both sets ensure continued airworthiness and could be used to cover any type of A/C utilization. This approach is an equivalent damage approach corresponding to trade of between FC/FH to better suit fleet utilization. As the both sets of thresholds/intervals ensure continued airworthiness and could be used any type of utilization, for 1st inspection and repetitive ones, operators may select either SR (Threshold or Interval) or LR (Threshold or Interval) (depending of the A/C utilization evolution). If a non optimal set of threshold/interval is selected, airworthiness will be ensured, but will penalize the operator because the inspection will be performed sooner than necessary as a consequence, the selection of SR or LR threshold and subsequent intervals can be change whenever. Threshold and Interval are whichever occurs first between FC and FH for selected set of threshold/interval between SR and LR. This means that the set FC/FH must be considered jointly (ie FCSR cannot be used with FHLR and vice versa).
