TITLE : WINGS - INSPECT REAR SPAR FOR CRACKS AT BUILD SLOT

MODIFICATION No. : None

REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

Cracks have been found in the rear spar web between Ribs 1 and 2 on both the in-service

aircraft and the fatigue test wing. In aLL reported cases the cracks span the tip of the

buiLd sLot and the nearest adjacent fastener hoLes. The cracks are considered to

initiate at the tip of the buiLd sLot and to be the result of fatigue damage created by

high shear stress experienced during the Landing cycle.

The earliest in-service damage was found on an A300 B2 aircraft which had achieved 21,500

Flight CycLes (FC)_ The crack in the fatigue test wing was discovered at 50,000

simulated FC and monitored for a further 12,000 FC with no evidence of continued crack

growth from the hoLe.

Modification No. 11130H5404 (Service BuLLetin No. A300-57-6063) has been introduced to

enlarge the end of the build sLot and cold expand seven hoLes adjacent to the buiLd sLot.

Embodiment of Modification No 11130H5404 (Service BuLLetin No. A300-57-6063) extends the

inspection threshold.

Mandatory High Frequency Eddy Current (HFEC) inspections are required of the aft face of

the rear spar web in the area immediately adjacent to the outboard end and bottom face of

the build sLot. Inspections are required at the threshoLds and repeat intervals given in

TabLes 1, 2, 3 and 4.

Production Modification 12102H5505 has been introduced on MSN 805. However, to support

operations beyond the Design Service GoaL (DSG), aircraft post production Modification

12101H5505 will need to be inspected using this Service Bulletin.

(2) Objective/Action

To carry out High Frequency Eddy Current (HFEC) inspections of the aft

face of the rear spar web in the area immediately adjacent to the

outboard end and bottom face of the buiLd sLot.

(3) Advantages

EarLy detection of cracks can prevent the necessity for expensive and
