ACCOMPLISHMENT INSTRUCTIONS Task 525020-832-848-001 - Inspection WARNING : MAKE SURE THAT YOU OBEY ALL THE WARNINGS AND ALL THE CAUTIONS INCLUDED IN THE REFERENCED PROCEDURES. CAUTION : ALWAYS OBEY THE PRECAUTIONS THAT FOLLOW TO KEEP ELECTRICAL WIRING IN A SATISFACTORY CONDITION (ELECTRICALLY AND MECHANICALLY SERVICEABLE) . WHEN YOU DO MAINTENANCE WORK, REPAIRS OR MODIFICATIONS, ALWAYS KEEP ELECTRICAL WIRING, COMPONENTS AND THE WORK AREA AS CLEAN AS POSSIBLE. TO DO THIS: - PUT PROTECTION, SUCH AS PLASTIC SHEETING, CLOTHS, ETC; AS NECESSARY ON WIRING AND COMPONENTS - REGULARLY REMOVE ALL SHAVINGS, UNWANTED MATERIAL AND OTHER CONTAMINATION. THESE PRECAUTIONS WILL DECREASE THE RISK OF CONTAMINATION AND DAMAGE TO THE ELECTRICAL WIRING INSTALLATION. IF THERE IS CONTAMINATION, REFER TO ESPM 20-55-00. CAUTION : IF A BUSH REPAIR HAS BEEN DONE ON A FRAME FORK THERE IS A LIFETIME LIMITATION. IF THE LIFETIME LIMITATION IS EXCEEDED, REPLACE THE FRAME FORK OR CARGO COMPARTMENT DOOR, REFER TO Fig. A-GBUAA Sheet 01 . NOTE : The accomplishment instructions of this Service Bulletin refer to procedures included in other AIRBUS documents. When the words ’refer to’ are used and the operator has an accepted alternative procedure, the accepted alternative procedure can be used. When the words ’in accordance with’ are included in the instruction, the procedure in the AIRBUS document must be used. NOTE : The access and close-up instructions, not comprising return to service tests, in this Service Bulletin do not constitute or affect the technical intent of the Service Bulletin. Operators can therefore, as deemed necessary, omit or add access and/or close-up steps to add flexibility to their maintenance operations as long as the technical intent of the Service Bulletin is met within the set parameters. NOTE : Manual titles given in the accomplishment instructions are referred to by acronyms. Refer to paragraph 1.J., References, for the definition of acronyms. NOTE : This Service Bulletin is classified mandatory or expected to be classified mandatory by an Airworthiness Directive (AD).

PROCEDURE NOTE : Paint peeling at fasteners head is an indicator of potential loose fasteners. Before reporting as loose, check as per SRM 51-42-11. During the cargo door inspection, it is necessary to look for loose, sheared or missing fasteners as an indicator of fatigue. Sheared or missing fasteners can be quickly identified as the result of the detailed inspection form outside, for the loose fasteners however it could be more difficult. In particular, based on the in-service experience, some fasteners affected by paint peeling can be wrongly considered loose due to the black marks around the fastener head, the so called "fastener rash" phenomenon. Recommendation to detect loose fasteners: - Paint chipping of fastener head detected form outside is a good indicator, but must not be the only evidence. - Check for abnormal gap under the fastener heads on both side. - Fastener movement (play) confirm the fastener is loose. However, sometimes the fastener can be loose and stuck (between skin and frame), that is why it is necessary to check on both side of the cargo door. **CONF 001 (1) Subtask 525020-210-202-001 - Identify the Part Number of the FWD Cargo Compartment Door Manpower Resources Manhours 0.50 Minimum number of person 1 Subtask elapsed time 0.50 Skills AIRFRAME (a) Has the FWD Cargo Compartment Door already been replaced in service. 1 If no go to SUBTASK 525020-220-201 001 Do a check and if necessary adjust the FWD Cargo Compartment Door Hook Gaps (only at first inspection) DATE: Aug 29/13 SERVICE BULLETIN No.: A340-52-5020 REVISION No.: 02 - Nov 27/15 Page: 30 6 Printed in FRANCE © AIRBUS S.A.S. 2007.
