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.
