Cover: Airframe Technology: Corrosion Control

From an OEM's perspective

Composite materials are also being evaluated as a possible remedy for the corrosion and aging issues associated with aluminum aircraft. Composites are not subject to corrosion in the same way that metallic structures are. However, if a metal is being used as a component of a composite material, corrosion could still occur. Therefore, careful considerations and insulation of metal components is a must during the design/development of composite assemblies containing metal.

In addition to its own corrosion-control efforts, Gulfstream relies on operators to share their knowledge of corrosion. The company has formed a number of teams, including a basic maintainability group, a safety review team, and a customer advisory board, to provide feedback on a host of topics, including corrosion.

When it comes to preventing corrosion, an aviation company’s work is never done.
