Job Set-Up SUBTASK A WARNING: MAKE SURE THAT THE AIRCRAFT IS IN A SAFE CONDITION BEFORE YOU DO THE MAINTENANCE PROCEDURES. THIS IS TO PREVENT INJURY TO PERSONS AND/OR DAMAGE TO THE EQUIPMENT. (1) Do the procedure to make the aircraft safe for maintenance (AMM TASK A/200). CAUTION: WHEN YOU COVER AN OPENING, MAKE SURE THAT YOU HAVE A SATISFACTORY VIEW OF THE COVER FROM THE GROUND. DO NOT OPERATE THE ENGINES WITH COVERS INSTALLED BECAUSE THE COVERS CAN COME OFF AND CAUSE DAMAGE TO THE ENGINES. USE COVERS, BLACK POLYETHYLENE SHEETS, AND YELLOW VINYL ADHESIVE TAPES TO KEEP LIQUIDS OUT OF THE DRAINS OF THE AIRCRAFT AND MAKE SURE THAT YOU HAVE A SATISFACTORY VIEW OF THE COVERS FROM THE GROUND. IF YOU DO NOT REMOVE THE A/300 Page 4 of 50 Rev 20 - Nov 11/10

5 COVERS FROM DRAINS, DAMAGE TO THE STRUCTURE CAN OCCUR. USE BLACK POLYETHYLENE SHEETS AND YELLOW VINYL ADHESIVE TAPES TO KEEP LIQUIDS OUT OF THE AREAS THAT CONTAIN MECHANICAL, ELECTRICAL, OR HYDRAULIC COMPONENTS. LIQUIDS THAT GET INTO THESE AREAS CAN CAUSE CORROSION, FREEZE DURING FLIGHT, OR REMOVE NECESSARY LUBRICANTS. MAKE SURE THAT THE PITOT PROBE COVER IS IN GOOD CONDITIONS AND DOES NOT SHOW EVIDENCE OF DAMAGE, SPECIALLY FRAYING AROUND ITS OPENING. FRAYED FIBERS FROM THE COVER, COMBINED WITH OTHER SUBSTANCES SUCH AS DIRT, GREASE, AND FLUIDS CAN CAUSE OBSTRUCTION OF THE PROBE. MAKE SURE THAT THE MIXTURE OF WATER DOES NOT GET ON THE STEEL OR CARBON BRAKE HEAT SINKS. CONTAMINATION CAN CAUSE DAMAGE TO THE CARBON AND STEEL BRAKES. (2) Do the aircraft normal parking procedures (AMM TASK A/200). WARNING: WHEN THE STATIC PORT IS COVERED, MAKE SURE THAT THIS CONDITION IS VISIBLE FROM THE GROUND. ALSO, ATTACH A REMOVE- BEFORE-FLIGHT TAG TO THE LEFT CONTROL YOKE IN THE COCKPIT. IF YOU DO NOT OBEY THIS PRECAUTION, ERROR TO THE AIRSPEED AND ALTITUDE SENSING SIGNALS CAN OCCUR, WHICH CAN CAUSE LOSS OF SAFE FLIGHT CONDITION. WARNING: DO NOT SPRAY DETERGENT OR WATER DIRECTLY INTO OR AT THE STATIC PORT. IF YOU DO NOT OBEY THIS PRECAUTION, DAMAGE TO THE STATIC PORT CAN OCCUR, WHICH CAN CAUSE LOSS OF SAFE FLIGHT CONDITION. WARNING: DO NOT PLACE ADHESIVE TAPE OVER THE HOLES OF THE STATIC PORT. IF YOU DO NOT OBEY THIS PRECAUTION, ERROR TO THE ALTITUDE SENSING SIGNALS CAN OCCUR, WHICH CAN CAUSE LOSS OF SAFE FLIGHT CONDITION. (3) Cover the static port with adhesive tape MEP and an orange vinyl streamer that has REMOVE BEFORE FLIGHT printed on it in black letters, as follows (Figure 302): WARNING: ALWAYS OBEY THE MANUFACTURER'S HEALTH AND SAFETY PRECAUTIONS WHEN YOU USE METHYL ETHYL KETONE (MEK). DO NOT GET MEK ON YOUR SKIN, IN YOUR EYES OR MOUTH, AND DO NOT BREATHE ITS FUMES. KEEP MEK AWAY FROM SPARKS, FLAMES OR SOURCES OF HEAT. PUT ON APPROVED PROTECTIVE CLOTHING, GOGGLES AND GLOVES. MEK IS POISONOUS AND FLAMMABLE, AND IF YOU DO NOT OBEY THESE PRECAUTIONS, INJURIES CAN OCCUR. (d) Clean the area around the static port with MEK or equivalent, and use a lint-free wiper cloth to apply the adhesive tape. Cover the holes of the static port with the orange vinyl streamer. Apply the adhesive tape MEP to the top and vertical edges of the orange vinyl streamer. Apply the adhesive tape MEP to each vertical edge of orange vinyl streamer. Make an overlap of adhesive tape MEP with the first strip A/300 Page 5 of 50 Rev 20 - Nov 11/10

6 (e) Apply the adhesive tape MEP horizontally on the orange vinyl streamer, under the static port holes. Make an overlap of adhesive tape MEP with the vertical strips. (4) Close the direct-vision windows (AMM SDS /1). (5) Close the doors as follows: Close the FWD passenger door (AMM SDS /1) Close the aft passenger door (AMM SDS /1) Close the FWD service door (AMM SDS /1) (d) Close the aft service door (AMM SDS /1) (e) Close the FWD cargo door (AMM SDS /1) (f) Close the aft cargo door (AMM SDS /1) (6) Do the step that follows, if applicable: NOTE: This procedure is recommended to prevent the flow of the water or clean product directly to the gaps of the doors. Seal the passenger, service, and cargo doors with adhesive tape or equivalent. F. Light Dirt - Cleaning SUBTASK A CAUTION: PUT ON GLOVES AND GOGGLES TO PREVENT INJURY TO YOUR SKIN AND EYES. USE A SAFETY HARNESS WHEN YOU ARE ON WET SURFACES ABOVE THE GROUND. CAUTION: OBEY THE MANUFACTURER'S INSTRUCTIONS WHEN YOU PREPARE AND APPLY CLEANING AND DISINFECTANT SOLUTIONS.

SUBTASK A (1) Do the procedure to make the ACFT safe for maintenance (AMM TASK A/200). F. Metal Surfaces - Cleaning SUBTASK A NOTE: When you make the lint-free wiper cloth moist, do not let the cloth touch the opening of the solvent container. This can cause contamination of the solvent source. Always apply the solvent to the lint-free wiper cloth from a distance or use a dispenser can specially designed to prevent contamination. (1) Clean the metal surfaces with solvents as follows: NOTE: We recommend that you apply a corrosion inhibitor on metal surfaces independently of the cleaning material that you use. Metal surfaces are normally treated or anodized to prevent corrosion. Normal wear, and abnormal use lead to corrosion, and it always has an effect on the ACFT. Do not abrade surfaces. Corrosion protection is normally a thin layer of anodized or organic agent. Abrasion can remove the protective film or coating. Do not let solvent dry on the surface. Do not use cloth a second time because this can make contamination to the surface. Make a lint-free wiper cloth moist with the solvent. Put the solvent on the cloth. Clean the metal surfaces with the solvent. Repeat as many times as necessary to remove all dirt. NOTE: For oxidation, powdery white corrosion, use corrosion inhibitor/cleaner. Dry the parts with a lint-free wiper cloth. (2) Clean the metal surfaces with BRULIN FORMULA 815MX as follows: NOTE: Use cool water for normal dirt and dust. Use warm water for oily surfaces A/300 Page 21 of 50

22 Prepare a solution of BRULIN FORMULA 815MX with cool or warm water from 32 to 49 C ( F). Prepare a solution with 1 part of BRULIN FORMULA 815MX to 64 parts of water by volume, for light dirt. You can increase the solution up to 1 part of BRULIN FORMULA 815MX to 10 parts of water by volume. Apply the solution with a spray gun, stiff-bristle brush, sponge or lint-free wiper cloth. Rub the surface with a wet sponge or lint-free wiper cloth. Do not let unwanted solution flow off to adjacent surfaces. NOTE: You can apply the material as a spray to the surfaces and rub them with a clean sponge or stiff-bristle brush Do not let unwanted solution touch porous surfaces. (d) (e) (f) Rub the dirty area as necessary, and apply the solution as many times as necessary to remove contamination. Flush the surface with a new sponge or a lint-free wiper cloth moist with clean water to remove remaining solution. Dry the surface with a lint-free wiper cloth. (3) Clean the metal surfaces with Calla 301-A Lemon as follows: NOTE: Use cool water for normal dirt and dust. Use warm water for oily surfaces. Prepare a solution of Calla 301-A Lemon with cool or warm water from 32 to 49 C ( F). Prepare a solution with 1 part of Calla 301-A Lemon to 4-8 parts of water by volume, for normal cleaning. For concentrated dirt or stains, use full strength. (d) (e) (f) Apply the solution with a spray gun, stiff-bristle brush, sponge or lint-free wiper cloth. Apply a spray of the solution to the surface and rub it with a lint-free wiper cloth or sponge. Do not let unwanted solution flow off to adjacent surfaces. NOTE: Do not let unwanted solution touch porous surfaces. Rub the dirty area as necessary, and apply the solution as many times as necessary to remove contamination. Flush the surface with a new sponge or a lint-free wiper cloth moist with clean water to remove remaining solution. Dry the surface with a lint-free wiper cloth. G.

Make a lint-free wiper cloth or sponge moist with the solution. Apply the solution to the surface. Use circular movements. Do not let unwanted solution flow off to adjacent surfaces. Rub the dirty area as necessary, and apply the solution as many times as necessary to remove contamination. Flush the surface with a new sponge or lint-free wiper cloth moist with clean water to remove remaining solvent. Dry the surface with a lint-free wiper cloth. (2) Clean the surfaces with BRULIN FORMULA 815MX: NOTE: Use cool water for normal dirt and dust. Use warm water for oily surfaces. Prepare a solution of BRULIN FORMULA 815MX with cool or warm water from 32 to 49 C ( F). Prepare a solution with 1 part of BRULIN FORMULA 815MX to 64 parts of water by volume, for light dirt.
