LANDING GEAR.
Before cleaning the landing gear, place a plastic cover or similar material over the wheel and brake
assembly.
1. Place a pan under the gear to catch waste.
2. Spray or brush the gear area with solvent or a mixture of solvent and degreaser, as desired. It may be
necessary to brush areas that were sprayed where heavy grease and dirt deposits have collected in order to
clean them.
3. Allow the solvent to remain on the gear from five to ten minutes, then rinse the gear with additional
solvent and allow to dry.
4. Remove the cover from the wheel and remove the catch pan.
5. Lubricate the gear per Lubrication Chart.
EXTERIOR SURFACES.
The airplane should be washed with a mild soap and water. Harsh abrasives or detergents used on painted
or plastic surfaces could make scratches or cause corrosion of metal surfaces. Cover areas where cleaning
solution could cause damage. Cover the mast of the gear back-up extender. To wash the airplane, the following
procedure may be used:
1. Flush away loose dirt with water.
2. Apply cleaning solution with a rag, sponge or soft bristle brush.
3. To remove stubborn oil and grease, use a cloth dampened with naptha.
4. Where exhaust stains exist, allow solution to remain on the surface longer.
5. Any good automotive wax may be used to preserve the painted surfaces. Soft cleaning cloths or a
chamois should be used to prevent scratches when cleaning or polishing. A heavier coating of wax on the
leading surfaces will reduce the abrasion problems in these areas.
WINDSHIELD AND WINDOWS.
1. Remove dirt, mud, etc., from exterior surfaces with clean water.
2. Wash with mild soap and warm water or an aircraft plastic cleaner using a soft cloth or sponge and a
straight rubbing motion. Do not harshly rub surfaces.
3. Remove oil and grease with a cloth moistened with kerosene.
—NOTE—
Do not use gasoline, alcohol, benzene, carbon tetrachloride,
thinner, acetone or window cleaning sprays.
4. After cleaning plastic surfaces, apply a thin coat of hard polishing wax. Rub lightly with a soft cloth.
Do not use a circular motion.
5. A severe scratch or mar in plastic can be removed by using jeweler’s rouge to rub out the scratch.
Smooth both sides and apply wax.
