CLEANING AND CARE
CAUTION
Excessive dirt deteriorates the flight performance.
8.5.1.
Painted Surfaces
To achieve the best flight characteristics for the DA20/100 KATANA, a clean external surface is most
important. For this reason it is highly recommended that the airplane, especially the leading edge of the wings
are kept clean at all times.
For best result, the cleaning is performed using a generous amount of water. If necessary, a mild cleaning
agent can be added. Excessive dirt such as insects etc. are best cleaned off immediately after flight, because
once dried they are difficult to remove.
Approximately once a year, the surface of the airplane should be treated and buffed using a
silicon free
automotive polish.
CAUTION
DO NOT use any cleaning agents containing silicon based materials.
8.5.2.
Canopy
The DA 20/100 KATANA offers excellent vision through a large plexiglass canopy. It is essential that care will
be taken while cleaning the canopy, as it is easily scratched. If scratched, the vision will be reduced.
In principal the same rules should be applied to clean the canopy as for the outside surface of the airplane. To
remove excessive dirt, plenty of water should be used; make sure to use only clean sponges and chamois.
Even the smallest dust particle can cause scratches.
In order to achieve clarity, plastic cleaners such as Permatex Part No. 403D
or Mirror Glaze
may be
used according to the manufacturer’s instructions. Do not wipe in circles, but only in one direction.
