### TITLE: NACELLES/PYLONS - INSPECT RIB 5 IN THE PYLON BOX **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES Two operators of A300 A/C fitted with GE engine pylons have reported cracks on the lower side of rib 5 in the pylon box. The concerned area is similar on A300/600 A/C fitted with GE engine pylons. The cracks were encountered on aircraft which have logged between 16,000 and 27,000 flight hours approximately. Investigations disclosed that these cracks are due to the stresses resulting from the pressure applied by the thrust reverser cowl bumpers. This Service Bulletin requested: - an High Frequency Eddy Current (HFEC) inspection and a detailed visual inspection on the lower side of rib 5. - in the event of crack findings, replacement of the stiffeners made out of bent extrusion by new thicker machined stiffeners as per Service bulletin No. A300-54-6031 (modification No. 11109S20987). Accomplishment of this Service Bulletin enables detection of cracks on the lower side of rib 5. The replacement of the stiffeners by Service bulletin No. A300-54-6031 (modification No. 11109S20987) cancels this inspection Service Bulletin. Accomplishment of this Service Bulletin is requested on GE CF6-80C pylons at 15,000 flight hours and subsequent inspections every 15,000 flight hours. For aircraft which have logged 15,000 flight hours, the inspection should be carried within 6,000 Flight Hours (FH) from Service Bulletin issuance.

F. APPROVAL The technical content of this document is approved under the authority of Design Organisation Approval No. EASA.21J.031. If an aircraft listed in the effectivity has a modification or repair embodied that is not of AIRBUS origin, and which affects the content of this Service Bulletin, the operator is responsible for obtaining approval by its airworthiness authority for any adaptation necessary before incorporation of the Service Bulletin. G. MANPOWER The manpower estimates given in this Service Bulletin are based on the direct labor cost to do the work. These estimates assume that the work will be done by experienced personnel, and may need to be revised upwards to suit operator’s circumstances.
