Corrosion is the gradual destruction of a metal surface due to exposure to natural elements such as moisture and humidity. In aviation, corrosion is a common problem, and if it is not handled properly, it can also become an expensive problem.
During standard aircraft operations, the high ground temperatures and low in-flight temperatures create moisture condensation, which penetrates any open, unprotected surface on the airframe. An effective corrosion prevention and control program is crucial in controlling airframe corrosion and reducing the high cost of corrosion repair and metal replacement. The application of an Ardrox AV CIC (Corrosion Inhibiting Compound) is an effective tactic for initial and on-going corrosion control.
These compounds can be applied to all internal metal surfaces of the airframe, excluding the fuel tanks. This includes leading and trailing edges, doors and door cut-outs, bulkhead, fuel tank, landing gear bays, fuselage floor area, fuselage crown area, lower structures, bilge areas, and keel-beam. Passenger and cargo doors, hull with stringers and frames, toilet area, fairings, antennas, and nose are also areas where these compounds can be applied.
The Ardrox AV product range offers a variety of corrosion inhibiting compounds with tailor-made properties.

Ardrox AV CICs are initially applied during the airframe manufacturing process but can be reapplied during the service life of the aircraft at periodic maintenance intervals. Many areas of the airframe will be inaccessible after manufacture until the first “C” or “D” check is done, which usually happens at around about a four year interval. During these overhauls, it is a good opportunity to apply Ardrox AV CICs within the normally hidden areas of the airframe. It must, of course, be applied properly and effectively to achieve the desired level of corrosion inhibition.
