28-26-04 Fuel Boost Pump - Removal / Installation

READ THE MATERIAL SAFETY DATA SHEETS FOR ALL MATERIALS. THE USER HAS THE RESPONSIBILITY FOR PROTECTION FROM INJURY AND EXPOSURE TO MATERIALS. THE USER HAS THE RESPONSIBILITY FOR COMPLIANCE WITH NATIONAL, FEDERAL, STATE AND LOCAL REQUIREMENTS FOR THE MATERIALS THAT ARE SPECIFIED. TO PREVENT A FIRE HAZARD FROM A FUEL SPILL, MAKE SURE THAT AN APPROVED CONTAINER IS AVAILABLE TO CATCH SPILLED FUEL BEFORE ALL FASTENERS ARE REMOVED. DO NOT ALLOW THE DRAINED FUEL TO STAY ON THE SKIN. WASH THE FUEL FROM THE SKIN WITH WATER. THE FUEL IS POISONOUS AND CAN BE ABSORBED INTO THE BODY. Procedure CAUTION PUT A TAG ON ALL ELECTRICAL CONNECTORS BEFORE THEY ARE DISCONNECTED TO PREVENT DAMAGE TO THE SYSTEM. NOTE Use the numbers in parentheses ( ) in connection with Figure 2. Fuel Boost Pump. 1 Disconnect the electrical connector (5) from the pump (4). 2 Remove the sealant from the bolts (1). 3 If necessary, position the Form-A-Funnel flexible draining tool below the pump (4). 28-26-04 Fuel Boost Pump - Removal / Installation August 31/20 Page 6 MAINTENANCE MANUAL NOTE The Form-A-Funnel flexible draining tool is used to block the wind from the fuel being drained and to prevent the fuel from draining into the Wing-to-Body Fairing (WTBF). 4 Remove the inner row of bolts (1) and washers (2) that attach the pump (4) to the canister (6). 5 Use two of the bolts (1) and put into the threaded hole locators (3) of the pump (4). 6 Alternately, tighten the bolts (1) in 1/2 turn increments until the pump (4) can be pulled straight out of the canister (6). CAUTION BEFORE THE FUEL BOOST PUMP IS REMOVED, PLACE THE CONTAINER UNDER THE BOOST PUMP TO CATCH THE SPILLED FUEL. THE FUEL BOOST PUMP AND CANISTER CONTAIN APPROXIMATELY 1/2 - 1 CUP OF FUEL. WHEN THE PUMP IS INITIALLY REMOVED THE FUEL CAN SPILL INTO THE REAR BEAM AREA AND LEAK INTO THE WING TO BODY FAIRING AREA. 7 Position the container under the pump and allow the fuel to drain from the pump. 8 Remove the O-rings (7) from the pump. 9 Discard the O-rings. CAUTION INSTALL THE CORRECT PROTECTIVE CAPS AND PLUGS ON THE ELECTRICAL CONNECTORS, LINES, TUBES, PORTS AND FITTINGS TO PREVENT EQUIPMENT DAMAGE. 10 Install protective caps and plugs on all open the ports and electrical connectors. 11 Remove the two bolts (1) from the pump (4) that were used in Step 5. Requirements After Job Completion Inspect the work area for foreign objects and damage. Record all maintenance in compliance with the National Aviation Authority Regulations. 28-26-04 Fuel Boost Pump - Removal / Installation August 31/20 Page 7 MAINTENANCE MANUAL 59734-TIL026013-001-73 A A A B 7 7 6 REF 3 3 2 1 5 4 REF B 6 4 Fuel Boost Pump Figure 2 28-26-04 Fuel Boost Pump - Removal / Installation August 31/20 Page 8 MAINTENANCE MANUAL Fuel Boost Pump – Installation Safety Conditions WARNING THIS MAINTENANCE PROCEDURE IS RELATED TO A CRITICAL DESIGN CONFIGURATION CONTROL LIMITATION (CDCCL) INTENDED TO PREVENT DEVELOPMENT OF IGNITION SOURCES IN OR ADJACENT TO THE FUEL TANK. DO THIS MAINTENANCE PROCEDURE CORRECTLY AND MAKE SURE THAT APPROVED PARTS AND MATERIALS ARE USED. IF THIS IS NOT DONE, IT CAN RESULT IN A FAILURE, MALFUNCTION OR DEFECT THAT ENDANGERS THE SAFE OPERATION OF THE AIRPLANE. MAKE SURE THAT ALL LANDING GEAR AND LANDING GEAR DOOR SAFETY DEVICES ARE INSTALLED BEFORE WORK IS DONE IN A WHEEL WELL OR IT CAN RESULT IN SERIOUS INJURY OR DEATH. SOME OF THE NECESSARY MATERIALS HAVE SAFETY, HEALTH AND ENVIRONMENTAL REQUIREMENTS. READ THE MATERIAL SAFETY DATA SHEETS FOR ALL MATERIALS.

TO PREVENT A FIRE HAZARD FROM A FUEL SPILL, MAKE SURE AN APPROVED CONTAINER IS AVAILABLE TO CATCH SPILLED FUEL. DO NOT ALLOW DRAINED FUEL TO STAY ON THE SKIN. WASH THE FUEL FROM THE SKIN WITH WATER. THE FUEL IS POISONOUS AND MAY BE ABSORBED INTO THE BODY. Procedure NOTE For the initial installation of the fuel pump, make sure that the pump liquid ring has been primed per the manufacturers instructions before installation. Failure to prime the liquid ring can result in the pump not priming and producing pressure. Use the numbers in parentheses ( ) in connection with Figure 3. Fuel Boost Pump. 1 Apply a thin layer of lubricant to the O-rings (7). NOTE A buildup of lubricant in the O-ring groove can prevent the O-ring from sealing properly. 2 Remove the protective caps and plugs from the ports. 3 Install the O-rings (7) on the pump (4). 28-26-04 Fuel Boost Pump - Removal / Installation August 31/20 Page 9 MAINTENANCE MANUAL CAUTION ONCE THE FUEL BOOST PUMP HAS BEEN INSERTED INTO THE FUEL BOOST PUMP CANISTER, THE CANISTER WILL BE FILLED WITH FUEL. IF IT IS NECESSARY TO PULL THE FUEL BOOST PUMP OUT OF THE FUEL BOOST PUMP CANISTER ONCE IT HAS BEEN INSERTED, PLACE A CONTAINER UNDER THE FUEL BOOST PUMP TO CATCH SPILLED FUEL. THE BURNISHED MATING SURFACES ON THE PUMP AND CANISTER MUST BE CLEAR OF ALL CONTAMINANTS OR LUBRICANTS SO THAT A ROBUST BONDING SURFACE IS MAINTAINED. 4 Install the pump (4) fully into the canister (6). The bolt hole pattern is not symmetrical. Make sure that the proper orientation of the pump with the canister before the pump is inserted into the canister. NOTE When the pump is pressed into the canister, there will be some resistance on the pump. 5 Hold the pump firmly and attach the pump (4) with the bolts (1) and washers (2). 6 Torque the bolts (1) to 40 - 50 inch-pounds (4.5 - 5.6 Nm). TECH _____ INSP _____ 7 Use the digital low resistance ohmmeter to do the test for electrical bond across the pump (4) and canister (6). Make sure that the resistance is no more than 0.0025 ohms. Refer to Electrical Bonding - General Maintenance, 20-24-01. 8 Fillet seal the attachment bolts (1) and washers (2) with sealant. Refer to Sealing Standard Practices - General Maintenance, 20-42-01. 9 Remove the protective caps and plugs from the electrical connectors. 10 Connect the electrical connector (5) to the pump (4). 11 If necessary, remove the Form-A-Funnel flexible draining tool from the aircraft. Requirements After Job Completion Inspect the work area for foreign objects and damage. Record all maintenance in compliance with the National Aviation Authority Regulations. 28-26-04 Fuel Boost Pump - Removal / Installation August 31/20 Page 10 MAINTENANCE MANUAL 59734-TIL026013-001-73 A A A B 7 7 6 REF 3 3 2 1 5 4 REF B 6 4 Fuel Boost Pump Figure 3 28-26-04 Fuel Boost Pump - Removal / Installation August 31/20 Page 11 MAINTENANCE MANUAL Fuel Boost Pump – Follow-on Maintenance Safety Conditions WARNING MAKE SURE THAT ALL LANDING GEAR AND LANDING GEAR DOOR SAFETY DEVICES ARE INSTALLED BEFORE WORK IS DONE IN A WHEEL WELL OR IT CAN RESULT IN SERIOUS INJURY OR DEATH.
