### TITLE: FUEL - TANK LEVEL SENSING - NEW OUTER TANK SENSOR HARNESS INSTALLATION **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR 13671H5745 MINOR None NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics affecting the airworthiness of the product. All other changes are major changes. REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES During maintenance work on a number of A300-600 aircraft, damage to the surge tank overflow sensor harness has been reported, approximately 30.0 cm (12.0 in.) inboard of the overflow sensor RIB 27. Investigations have shown that the damage has been caused by contact of the harness against the Magnetic Fuel Level Indicator (MFLI) canister. The cause of the contact is due to incorrect installation of the harness. As the MFLI is integral to the access panel in this location any potential contact is hidden. Harness chafing against the MFLI has previously been seen in this location. Modification 04489 was introduced in production to improve the harness installation and prevent contact of the harness with the MFLI. As part of SFAR88 activities embodiment of the Modification 04489 was required by embodiment of mandatory Modification Service Bulletin A300-28-6020. The configuration of the Post-Mod 04489 installation is considered to be subject to human error, given the subsequent in-service findings leading to variability of installation and potentially resulting in contact with the MFLI canister. To avoid the possibility of incorrect harness installation, the angle brackets attached to stringer 15 between RIBS 26 and 27 are to be replaced by new brackets to provide adequate clearance of the cable from the MFLI canister. The new brackets contain error-proofing measures that ensure consistent installation.

# @A300-600 SERVICE BULLETIN SUMMARY Prior to modification, if a harness is found to be damaged during inspection, depending upon the nature and extent of the damage a repair is available within this Service Bulletin Damage that falls outside the limits identified in this Service Bulletin will require specific repair instructions from Airbus. Accomplishment of this Service Bulletin will ensure that the fuel level sensor harness is correctly routed and that adequate clearance to the MFLI canister can be maintained.

# @A300-600 SERVICE BULLETIN Harness chafing against the MFLI has previously been seen in this location. Modification 04489 was introduced in production to improve the harness installation and prevent contact of the harness with the MFLI. As part of SFAR88 activities embodiment of the Modification 04489 was required by embodiment of mandatory Modification Service Bulletin A300-28-6020. The configuration of the Post-Mod 04489 installation is considered to be subject to human error, given the subsequent in-service findings leading to variability of installation and potentially resulting in contact with the MFLI canister. (2) Objective/Action To avoid the possibility of incorrect harness installation, the angle brackets attached to stringer 15 between RIBS 26 and 27 are to be replaced by new brackets to provideadequate clearance of the cable from the MFLI canister. The new brackets contain errorproofing measures that ensure consistent installation.
