7. AIRPLANE CARE
The airplane is most easily and safely maneuvered during ground handling by the tow-bar attached to the nose gear. However, due to the castoring nature of the nose wheel, it may be necessary to apply weight to the rear of the aircraft in order to lift the nose wheel off the ground if it is required to move the aircraft backwards.
Proper tie-down procedure is the best precaution against damage to a parked airplane by wind. The mooring procedure is as follows:
Set parking brake and lock control stick (using seat belt)
Install the tie down fittings into the receptacles under each wing and under the tail
Tie sufficiently strong ropes to these tie-down fittings and secure each rope to the ground
Install pitot tube and LRI probe covers
Fit and secure aircraft cover
The Acrylic windshield and windows should be cleaned with an aircraft windshield cleaner. Fine scratches can be polished out using Micromesh or a commercial wax.
Never use gasoline, benzine, alcohol, acetone, carbon tetrachloride, lacquer thinners or glass cleaner to clean the Acrylic. These materials may attack the plastic and cause it to craze.
Generally, the painted surfaces can be kept bright by washing with water and mild soap, followed by a rinse with water and drying with a chamois. If desired, waxing can be done with a good automotive wax. Any touch-ups should be done before the waxing, but after washing.
Small nicks, particularly near the tips and on the leading edges should be filled and sanded as soon as possible.
Dust and loose dirt can be removed by regular cleaning with a vacuum cleaner. Soiled upholstery may be cleaned with foam-type detergent. Refrain from using any volatile solvents. Similar cleaning agents as used in the home can be used in the cockpit.
Aircraft that are not in daily flight should have the engine started and warmed at least once a week. This process replaces oil that has drained from internal surfaces while standing idle. Warm up should be in such a manner to produce oil temps in the region of 170F. Maximum CHT’s must never be exceeded in ground operation. Keep fuel tanks full to minimize condensation.
8. AIRFRAME AND SYSTEMS MAINTENANCE
Remove upper and lower cowls
Remove inspection covers under wings – outboard wing bolt, aileron, landing light Remove rear baggage bulkhead

Inspect all controls surface hinges.
Check control surface movements.
Inspect main and rear wing bolts
Inspect door hinges, and door lock mechanism
Inspect rudder pedals and brake cylinders
Check brake fluid level
Inspect brake tubing
Inspect fuel tubing, and selector valve
Landing gear:
Check brake pads for wear
Check tyres for wear, and damage
Grease wheel bearings and “H” bracket rod end
Check main castoring castle nut for security
Inspect gear legs for cracks, damage, corrosion, and bending

Check ELT battery date. Replace batteries if date expires in less than one year. When replacing the batteries mark the outside of the ELT battery case with the expiration date as indicated on the new batteries.
Check the ELT battery voltage reading
Remove and clean fuel tank screens
Check control surface hinges
Clean vacuum system air filters
As per annual, and in addition:
Functional test of altimeter
Functional test of airspeed indicator
Compass swing
Change engine air filter
