Flugzeugreparaturen Ralf Kohnen Aircraft MRO and Metal Fabrication

Today's aircraft are highly technical structures that contain many different and complex systems. For each of these systems there is a specialist. Flugzeugreparaturen Ralf Kohnen specializes in aircraft structural repair through metal fabrication. The demanding requirements of custom metal fabrication are often underestimated, particularly during accident and C / D-Check repair actions. A broad experience level coupled with craftsmanship is a prerequisite for a high-quality and lasting repair.
