### TITLE: FUEL - VENTING SYSTEM - INSPECTION OF FUEL VENT PROTECTOR **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES The Fuel Vent Protector PN 786073-1-0 FIN 194QM (195QM) is part of the stack pipe connected to the National Advisory Committee for Aeronautics (NACA) Vent Intake Assembly. If a ground fire occurs, it prevents the ignition of the fuel vapour in the surge tank (and therefore, the venting system). It also allows air to flow freely through it in two directions and prevents ice formation. The Fuel Vent Protector consists of an ice protector cartridge and a flame arrestor cartridge within a metal body. A circlip holds the ice protector and flame arrestor cartridges in position. More than one circlip out of a batch of 400 produced by the vendor Intertechnique in August 2012, were found corroded. Several circlips have been found to be corroded due to a surface treatment (shot peening) operation being omitted during manufacture. Two suspect circlips have been inspected and the presence of corrosion has been confirmed. Fuel Vent Protector FIN 48QM (49QM) are not affected by this Service Bulletin. This Inspection Service Bulletin introduces a one-time Detailed Inspection of the Fuel Vent Protector. If the Part Number (PN) and Serial Number (SN) of the Fuel Vent Protector are found to be part of the affected batch, the Fuel Vent Protector (containing the circlip) must be replaced. This one-time inspection will detect affected units and prevent possible future in-service issues.

3. ACCOMPLISHMENT INSTRUCTIONS Task 281221-832-895-001 - Inspect the Fuel Vent Protector WARNING: MAKE SURE THAT YOU OBEY ALL THE WARNINGS AND ALL THE CAUTIONS INCLUDED IN THE REFERENCED PROCEDURES. WARNING: THIS INSTRUCTION IS APPLICABLE TO A CRITICAL DESIGN CONFIGURATION CONTROL LIMITATION (CDCCL) ITEM. CAREFULLY OBEY ALL GIVEN INSTRUCTIONS WHEN YOU DO THIS STEP. IF YOU DO NOT OBEY THESE INSTRUCTIONS, A DANGEROUS CONDITION CAN OCCUR THAT CAN CAUSE A POSSIBLE FUEL TANK EXPLOSION. 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. NOTE: The accomplishment instructions of this Service Bulletin include procedures given in other documents or in other sections of the Service Bulletin. When the words ’refer to’ are used and the operator has a procedure accepted by the local authority he belongs to, the accepted alternative procedure can be used. When the words ’in accordance with’ are used then the given procedure must be followed. 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). The paragraphs 3.C. and 3.D. in these accomplishment instructions are Required for Compliance (RC) and must be done to comply with the AD.
