General Atomics AeroTec Systems (GA-ATS) is manufacturing the new Do228 NXT special mission aircraft in Germany. Many main components, including the wings, are now made in-house. Importantly, GA-ATS has introduced a new surface treatment process called tartaric sulfuric acid anodizing (TSAA) during production.
Corrosion protection is critical for aircraft. It prevents damage like rust, which can threaten structural safety. Aircraft face extreme conditions, so protecting metal parts is essential. Anodizing coatings extend service life, reduce maintenance, and ensure safety. This is why TSAA was chosen for the Do228 NXT.
Compared to its predecessor, the Do228 NG, which used chromic acid anodizing for wing coating, GA-ATS now uses TSAA. This change reflects modern manufacturing standards and compliance with the EU’s REACH chemical regulations.
TSAA offers several advantages. It provides strong corrosion protection and excellent adhesion. The process forms a thicker oxide layer, making the coating more robust and resistant to wear. Additionally, TSAA is more environmentally friendly than previous methods, aligning with sustainability goals.
Furthermore, the Do228 NXT development involved modernising many aircraft components and updating production processes. This combination of innovation and eco-conscious manufacturing highlights GA-ATS’s commitment to quality and safety.
After successfully completing TSAA test runs earlier this year, GA-ATS is now incorporating this coating into the Do228 NXT series production. This step ensures the new aircraft benefits from advanced corrosion resistance and environmentally responsible manufacturing.
GA-ATS’s adoption of TSAA marks a significant step forward. It strengthens the Do228 NXT’s durability while supporting greener production practices. This approach underlines the company’s focus on blending modern technology with sustainability and aviation safety.
