The test bench was in post Mod. No. 41652S12091 (WINGS - SECTION 15/21 - MODIFY KEEL FITTING BEAM/FORWARD LOWER FUSELAGE JOINT) production solution configuration. The intention of the production solution was also proposed by Service Bulletin A330-57-3032 for retrofit. The structural analysis has led to the issue of the Inspection Service Bulletin A330-57-3081 (WINGS - CENTER WING BOX - INSPECTION OF KEEL BEAM FASTENER HOLES AT FRAME 40 (UNREPAIRED AIRCRAFT)). The Inspection Service Bulletin requires a detailed inspection on A330 aircraft pre Mod. No. 49202S16307 (FUSELAGE - CENTER FUSELAGE - REINFORCE SECTION 15/21) including mandatory and recommended thresholds and repetitive inspection intervals. This Service Bulletin recommends to modify the fasteners installation in the junction of the keel beam fitting at FR40. Accomplishment of this Service Bulletin cancels the inspection requirements of Service Bulletin A330-57-3081 for aircraft on which Mod. No. 44360S13013 (WING - CENTER WING - MODIFY FR40 and FRONT SPAR) in not embodied.
