APPLICATION OF SOLID PAINT COATING ON AIRCRAFT

Abstract

Applying solid paint is a procedure used in practice to cover an aircraft skin with a coat of chromatic lacquer which possesses anti-corrosion properties. Additionally, this coat improves aerodynamic characteristics of a/c skin. Solid paint is applied as a preventive maintenance of the material the skin is made of to protect it against atmospheric exposure factors and it is conducted before an a/c is certified airworthy or when a given assembly requires separate maintenance or repair , and even in case of faults removal of skin coating fragment during scheduled maintenance. Painting process is conducted in a specially designated room which needs to meet a number of requirements and occupational safety regulations. The most important factor which the painting shop must meet is an appropriate room temperature, air-conditioning system and fire extinguishing equipment. The process of applying solid paint is timeconsuming and requires precision. The author presents chosen methods of applying solid paint on aircraft construction elements as well as painting process preparatory maintenance. The article presents specificity of the preparatory process starting with appropriately prepared room, protective clothing and equipment suitable for solid paint application and ending with appropriate humidity parameters. The contents of the article depicts conditions which have to be met so that the process is accomplished in a safe manner and according to technological procedures. Subsequent stages of the paint application process show complex technology and influence of many factors which guarantee correct and safe task execution. Correct and technologically appropriate removal of the old lacquer layer, aircraft washing and finally outer layers application guarantee high quality, durability and safety of air crews and passengers.
