EFFECTIVITY: CIJ ALL

TASK 12-25-01-103-001

2. Clean (Water Wash) the External Surfaces of the Airplane

A. General

(1) This section includes these procedures:

(a) Remove Light Material (dust and dirt) from Smooth Surfaces

(b) Remove Moderately Heavy Material (oil and mud) from Smooth Surfaces

(c) Remove Heavy Material (grease and exhaust particles) from Smooth Surfaces

(d) Remove Material Around Sensitive Components

(e) Remove Unwanted Hydraulic Fluid

(f) Clean With Foam

NOTE: Boeing considers water pressure above 80 psi to be "high pressure".

(2) Use the Remove Material Around Sensitive Components procedure to clean the areas that contain mechanical, electrical, or hydraulic components. These areas include the wheel wells, flight control surfaces, and landing gear.

(3) When moderately heavy or heavy material removal is necessary, remove the heavier material first. Then clean the airplane with the procedure for light material removal.

(4) To clean large areas, use non-atomizing spray equipment, swabs, and brushes. To clean small areas, use rags, brushes, and sponges. Do not clean an area so large that the cleaner dries on the surface before you can flush it with water.

(5) Do not clean with water that is hotter than 160°F.

(6) To clean the windows in the flight compartment, refer to PAGEBLOCK 12-16-02/301, Flight Compartment Windows.

(7) To clean the windows in the passenger compartment (if applicable), refer to PAGEBLOCK 12-16-03/301, Passenger Windows.

EFFECTIVITY: CIJ ALL

NOTE: Be careful when you clean the airplane in very hot weather. The heated surface of the airplane can dry the cleaners before you can flush them with water. The dried cleaners can stain the surface.

SUBTASK 12-25-01-503-002

WARNING: KEEP ALL OF THE EQUIPMENT THAT YOU USE WITH FLAMMABLE SOLVENTS

AWAY FROM SOURCES OF HEAT. IF THERE IS WIND, MAKE SURE THE

SOLVENTS DO NOT FALL ON ELECTRICAL EQUIPMENT OR WARM

COMPONENTS.

(1) Move all of the equipment that you will use with flammable solvents away from sources of heat.

SUBTASK 12-25-01-863-003

(2) Statically ground the airplane (PAGEBLOCK 20-41-00/201).

SUBTASK 12-25-01-863-052

(3) Remove electrical power (PAGEBLOCK 24-22-00/201).

SUBTASK 12-25-01-843-004

(4) Close all of the passenger doors, cargo doors, emergency exits, and access doors and panels.

SUBTASK 12-25-01-843-039

WARNING: WHEN THE PITOT PROBES ARE COVERED, MAKE SURE THAT CONDITION IS

VISIBLE FROM THE GROUND. IN ADDITION, ATTACH A TAG TO THE LEFT

CONTROL WHEEL IN THE FLIGHT DECK AS A REMINDER THAT PITOT PROBES

ARE COVERED. FAILURE TO OBSERVE AND REMOVE COVERINGS OVER PITOT

PROBES BEFORE FLIGHT MAY CAUSE LARGE ERRORS IN AIRSPEED-SENSING

AND ALTITUDE-SENSING SIGNALS, WHICH MAY LEAD TO LOSS OF SAFE

FLIGHT.

CAUTION: USE COVERS, BLACK POLYETHYLENE SHEET, AND YELLOW VINYL ADHESIVE

TAPE TO KEEP LIQUIDS OUT OF AREAS THAT CONTAIN MECHANICAL,

ELECTRICAL, OR HYDRAULIC COMPONENTS. LIQUIDS WHICH ENTER THESE

AREAS CAN CAUSE CORROSION, FREEZE DURING AIRPLANE FLIGHT, OR

REMOVE NECESSARY LUBRICANTS.

CAUTION: WHENEVER AN OPENING IS COVERED, MAKE SURE THAT CONDITION IS

VISIBLE FROM THE GROUND. ENGINES SHOULD NOT BE OPERATED WITH

COVERS IN PLACE BECAUSE THE COVERS CAN COME OFF AND DAMAGE THE

ENGINES.

CAUTION: MAKE SURE THE PITOT PROBE COVERS ARE IN GOOD WORKING CONDITION

WITH NO EVIDENCE OF DAMAGE, ESPECIALLY FRAYING AROUND THE COVER

OPENING. FRAYED FIBERS FROM THE COVER COMBINED WITH OTHER

SUBSTANCES SUCH AS DIRT, GREASE AND FLUIDS CAN CAUSE OBSTRUCTION

IN THE PROBE.

(5) Put the covers on these components:

(a) Pitot probes (SeeFigure 301)

(b) Engine inlet, fan exhaust, and turbine exhaust (PAGEBLOCK 71-00-03/201)

(c) Install the probe cover, SPL-1513 on the ice detector probes.

(d) Install a angle of attack vane cover, COM-2499 on the angle-of-attack vane.

(e) Install the probe cover, COM-1519 on the total air temperature probes.

(f) Brakes

(g) Tires

(8) Use G02219 Scotch Brand No.471 tape and G02443 barricade tape that has "REMOVE BEFORE FLIGHT" printed on it in black letters to cover the alternate static ports and elevator feel static ports in the following manner (see Figure 301. See Figure 302 for illustrations of the static port cover placement procedure for alternate and elevator feel static ports):

WARNING: DO NOT PLACE 3M NO. 471 YELLOW VINYL ADHESIVE TAPE OVER THE

HOLES OF THE STATIC PORTS.

(a) Clean the area around each static port with B00316 solvent or equivalent, and a clean dry rag where you will put the 3M No. 471 yellow vinyl adhesive tape (see Figure 302).

(b) Place one end of approximately a 4-foot piece of the orange barricade tape over the holes of the static port and secure the upper edge with 5 inches of No. 471 yellow vinyl adhesive tape (see Figure 302 (Sheet 1) steps 1 and 2).

NOTE: Smooth the 3M No. 471 yellow vinyl adhesive tape on the airplane surface to make sure the bond is satisfactory.

1) Do not put vinyl adhesive tape over the holes of the static port.

(c) Put a 5-inch piece of vinyl adhesive tape on each vertical edge of the barricade tape overlapping the first strip of adhesive tape. (See Figure 302 (Sheet 1) step 3)

(b) Place one end of a 4-foot piece of the orange barricade tape over the holes of the upper primary static port and secure the upper edge with 5 inches 3M No. 471 yellow vinyl adhesive tape (see Figure 302 (Sheet 2), Steps 1 and 2).

NOTE: Smooth the 3M No. 471 yellow vinyl adhesive tape on the airplane surface to make sure the bond is satisfactory.

1) Do not put vinyl adhesive tape over the holes of the static ports.

(c) Put an 8-inch strip of 3M No. 471 yellow vinyl adhesive tape on each vertical edge of the barricade tape overlapping the first strip of adhesive tape (see Figure 302 (Sheet 2), Step 3).

(d) Put an 8-inch strip of 3M No. 471 yellow vinyl adhesive tape below the lower primary static port holes overlapping the two vertical strips of adhesive tape (see Figure 302 (Sheet 2), Step 4).
