8.5. CLEANING AND CARE
CAUTION
Excessive dirt deteriorates the flight performance.
8.5.1. Painted Surfaces
CAUTION
DO NOT USE ANY CLEANING AGENTS CONTAINING SILICON
BASED MATERIALS. ONCE APPLIED, SILICONE IS DIFFICULT
TO REMOVE. SILICONE MAY RESULT IN CONTAMINATED
BONDING SURFACES IF THE AIRCRAFT WERE EVER IN
NEED OF STRUCTURAL REPAIR.
To achieve the best flight characteristics for the DA20-C1, 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 results, 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.
8.5.2. Canopy
The DA20-C1 offers excellent vision through a large plexiglass canopy. It is essential that care
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.
