### TITLE: WINGS - CENTER WING - INSPECTION OF THE PRESSURIZED FLOOR FITTINGS AT FRAME 36 **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES During the center fuselage fatigue test, damage was found on the pressurized floor fittings at Frame (FR) 36, below the lower surface panel. The damage (crack caused by bending) spread through the thickness and resulted in breakage fitting. In the frame of the Extended Service Goal exercise based on new fatigue tests, analyses of finding on MSN 0004 dismantling and following fleet utilization evolution, Threshold and Intervals have been revised. This Service Bulletin requires the inspection of the pressurized floor fittings at Frame FR 36 with new Threshold and Intervals. Accomplishment of this Service Bulletin will contribute to maintain the structural integrity of the fittings at FR36. Accomplishment of Service Bulletin No. A320-57-1029 (Mod. No. 21282P1497) cancels the instructions described in this Service Bulletin.
