ATA SYSTEM : 57 TITLE : WINGS - MAIN LANDING GEAR ATTACHMENT - INSPECTION OF THE MLG RIB 5 AFT BEARING FORWARD LUG MODIFICATION No. : None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES During routine maintenance, a crack has been found visually in the forward lug of the MLG rib 5 aft bearing attachment on two A310 in-service aircraft. The concerned aircraft had accumulated 24,000 Flight Cycles (FC) and 27,000 FC at the time of finding (Refer to OIT 999.0115/06). In both cases the cracks extended through the entire thickness of the forward lug. The examination of the cracked ribs has confirmed that the crack originated due to the presence of pitting corrosion in the forward lug holes. Other small corner crack sites were also identified within the corroded region adjacent to the crack. Also on both aircraft medium to heavy corrosion was found in the forward lugs on the opposite wing after removal of the bushes. As an interim measure the Alert Service Bulletin (ASB) A300-57A6105 was issued to introduce a repetitive Detailed Visual Inspection (DVI) of the forward lug of the MLG Rib 5 aft bearing attachment. This Inspection Service Bulletin introduces a repetitive inspection program to detect a crack in the forward lug of the RH and LH MLG Rib 5 aft bearing attachment. Operators now have the choice to perform an ultrasonic inspection or a DVI. The ultrasonic inspection will detect any crack at an early stage and limit the risk of extensive repairs. This earlier crack detection is not possible with the DVI. If no crack is found the operator has the option to embody the modification Service Bulletin A300-57-6106 (Mod No. 13348H5689) or to perform repeat inspections. The embodiment of Service Bulletin A300-57-6106 (Mod No. 13348H5689) is strongly recommended and will cancel the inspection requirements of this Service Bulletin.

NOTE : Aircraft which have had Service Bulletin A300-57-6106 (Mod No. 13348H5689) embodied or which have had oversized interference fit bushes installed in the LH and/or RH MLG rib 5 aft bearing forward lugs as per Repair R57240221 are not affected by this Service Bulletin. If oversized interference fit bushes have been installed as per Repair R57240221 on one wing only, then the opposite wing must be inspected. The repeat inspections will make sure that any crack in the inspection area on the forward lug of the MLG rib 5 aft bearing attachment will be identified.

(3) Advantages The repeat inspections will make sure that any crack in the inspection area on the forward lug of the MLG rib 5 aft bearing attachment will be identified. (4) Operational/Maintenance Consequences None D. DESCRIPTION To accomplish this Service Bulletin it is necessary to : (1) Config. 01 (a) Make the work area safe. (b) Get access to the forward lugs of the LH and RH MLG rib 5 aft bearing attachment. (c) Do a DVI or an ultrasonic inspection. (d) Close up and complete the documentation. E. COMPLIANCE (1) Classification Mandatory (2) Accomplishment Timescale (a) A DVI or Ultrasonic Inspection of the MLG Rib 5 is mandatory before accumulation of 12,000 FC from new or from the MLG Rib 5 replacement when applicable. If a MLG Rib 5 has been changed on one side only then the RH and LH should be considered separately. If the 12,000 FC threshold has been exceeded then the first inspection is mandatory within 10 calendar days from receipt of this Service Bulletin. 1 If there are no findings, a repeat inspection is required until accomplishment of Service Bulletin A300-57-6106 (Mod No. 13348H5689) at the intervals that follow : — DVI every 100 FC — Ultrasonic Inspection every 675 FC.

DATE : Aug 08/07 SERVICE BULLETIN No. : A300—57—6107 REVISION No. : 00 — Page : Printed in FRANCE © AIRBUS, 2007 All rights reserved NOTE : If the ASB A300-57A6105 has been accomplished then the next DVI should be 100 FC from the last inspection accomplished by ASB A300-57A6105. 2 In case of findings per the visual inspection, the MLG Rib 5 fitting will have to be replaced before the next flight. 3 In case of findings per the ultrasonic inspection and if no crack is visible, aircraft can continue operation up to the accomplishment of the Repair Instruction R57240221, providing a repeat visual inspection is performed every 36 calendar hours with no findings. In case of findings from the visual inspection, the fitting will have to be replaced before the next flight. NOTE : The ultrasonic inspection will detect any crack at an early stage and limit the risk of extensive repairs. This earlier crack detection is not possible with the DVI. NOTE : Aircraft which have had Service Bulletin A300-57-6106 (Mod No. 13348H5689) embodied or which have had oversized interference fit bushes installed in the LH and/or RH MLG rib 5 aft bearing forward lugs as per Repair R57240221 are not effected by this Service Bulletin. If oversized interference fit bushes have been installed as per Repair R57240221 on one wing only, then the opposite wing must be inspected. (b) Accomplishment of this Service Bulletin is expected to be rendered mandatory by the issue of an Airworthiness Directive (AD) published by the European Aviation Safety Agency (EASA). It is anticipated that the AD will confirm the (thresholds and/or intervals and/or date) given above but reference should be made to the AD for confirmation of the mandated accomplishment timescale. F. APPROVAL Approved under EASA 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. The estimates do not include the time to prepare, plan or inspect the work. Manufacture and
