than tying it down outside will greatly extend the airframe’s life.
CAUTION
If high pressure washing equipment is used to wash your
Sportsman, keep the stream of water away from wheel
bearings, propeller hub bearings, pitot-static ports, electrical
and avionics equipment, etc. Avoid directing the stream
toward the wings and tail surfaces from the rear where the
water can more easily enter the structure.
The Sportsman’s fiberglass composite fuselage structure is not subject
to corrosion like the aluminum portions of the airframe, but extended
exposure to the ultraviolet radiation in sunlight will cause the gel coat
to oxidize, requiring buffing to restore the original gloss. If the airplane
is to be tied down outside for an extended time, we recommend
covering the fuselage with a protective slip cover to prevent paint
oxidation.
Minor surface cracking of the composite fuselage is usually just a
cosmetic concern and not a structural problem. If surface cracks
appear in the finish in a high stress or vibration area, however, it may
indicate damage to the underlying structure. Check the fiberglass
structure below the finish by sanding down to the fiberglass laminate.
Do not sand into the laminate.
If the fiberglass structure is damaged,
it will have a white colored ridge or notch, indicating torn or
compressed fibers. If no damage has occurred to the structure, the
glass will be smooth and translucent. If damage has occurred, contact
Glasair Aviation for repair consultation.
