Section 11 – PAINTING AND COATINGS
11.1. GENERAL
This Section identifies the line maintenance, minor repair, and minor alteration tasks that can be
accomplished in the aircraft Painting and Coatings by the Aircraft owner (only for ELSA), a Sport Pilot or
higher or a holder of an LSA repairman certificate with either an inspection or maintenance rating.
No heavy maintenance, major repairs, or major alterations, as outlined in ASTM F2483 Sections 7
through 9, are authorized at this time, for this ALTO aircraft fuel system.
Any heavy maintenance, major repairs, or major alterations, as outlined in ASTM F2483 Sections 7
through 9, can only be performed by Direct Fly S.R.O. or only as provided by Direct Fly‘s’ approved
engineering data.
11.2. DESCRIPTION
11.2.1. Safety rules
When working with paints, thinners and solvents follow the following safety rules:
•
it is necessary to follow safety rules for working with flammable and volatile substances
•
working area must be properly aerated
•
it is prohibited to smoke and anyway handle with free fire in a working area
•
use protective working means such as goggles, gloves, respirator, etc.
11.2.2. Recommendation for paint repairs
By applying paints weight of airplane is increased and center of gravity position is changed. Increase
in weight depends on type of coat and its thickness.
11.2.2.1.
Washing and degreasing
It is possible to use both organic solvents and solvents based on water.
(a) Organic solvents - acetone, methyethyl-ketone (MEK), benzene, toluene, BASF Glasurit 360-4
•
Applied by spraying on washed surfaces (e.g. mechanical sprayer, jet ejector) or by
wiping with wet (by pouring, not by dipping because it would contaminate the whole
volume of solvent) textile wad. After applying it, the agent is wiped off by clean absorbing
material before solvent evaporation.
•
Advantages: fast and reliable evaporation even from the corners and borders without
additional warming.
•
Disadvantages: it must be used without other dilution (expensive); not ecological
(danger of water contamination); detrimental to health (must be carried out in an aerated
area with personal protective means); waste (including dripping from the area) must be
eliminated in the incinerating plants.
•
Use: for Al-alloys surfaces, epoxy fiberglass
