Maintenance
9.) Tire Care:
For maximum service from the tires, keep them inflated to the proper pressures. When
checking tire pressure, examine the tires for wear, cuts and bruises.
All wheels and tires are balanced before installation, and the relationship of tire, tube and wheel
should be maintained when servicing. Unbalanced wheels can cause extreme vibration in the
landing gear. In the installation of new components, it may be necessary to re-balance the
wheels with the tires mounted.
10.)
Lubrication:
Lubrication at regular intervals is an essential part of the maintenance of any aircraft. The
Service Manual contains charts showing lubrication points, types of lubricants to be used, and
recommended frequency of application. Refer to the Service Manual for detailed lubrication
instructions and methods.
CLEANING
1.) Windshield and Window Care:
The Plexiglas windshield and windows should be cleaned with an aircraft windshield cleaner
following directions supplied with the cleaner. If windshield cleaner is not available, the
Plexiglas can be cleaned by using water and a mild soap to remove dirt and loose particles.
After cleaning, apply a thin coat of a good commercial wax. A severe scratch or mar can be
removed with Plexiglas polish.
Oil and grease can be removed with kerosene or Stoddard solvent. Never use gasoline,
benzine, alcohol, acetone, paint or lacquer thinner, or glass cleaner to clean the Plexiglas.
These materials will attack the plastic and cause it to craze.
2.) Exterior Surfaces:
The airplane should be washed with a mild soap and water. Harsh abrasives or alkaline
detergents can cause scratches on painted and plastic surfaces or cause corrosion of metal. Oil
and grease can be removed with kerosene or Stoddard solvent. Any good auto wax may be
used to preserve painted surfaces.
3.) Interior Care:
Clean side panels, seats and carpet with a stiff-bristle brush and vacuum cleaner. Soiled
upholstery may be cleaned with a good upholstery cleaner suitable for the material. Carefully
follow the instructions supplied with the product.
