By: Bruce Peever, Technical Services Corrosion, which can be defined as the deterioration of metal by its reaction to its environment, is a process by which a metal tries to return to its natural state. For aluminum, this means corroding back to bauxite, while steel rusts to iron oxide.
Certain environmental factors are not under operator control, such as the salt-laden atmosphere in marine locations or the airborne pollutants of industrial areas. Regular inspection and corrosion prevention becomes an important variable in such circumstances.
Bombardier previously published Environmental Corrosion Control and Prevention Guidelines, an Infoservice newsletter. This newsletter is a compilation of references and information to assist maintenance crews in developing customized maintenance practices when their aircraft is exposed to harsh environments. This newsletter can be found on the myBombardier.com website.
To supplement the Bombardier Infoservice newsletter, Rolls-Royce has published a BR700 Corrosion Prevention & Control Guide, which is now available on the Rolls-Royce care website. Please refer to this document for more detailed guidance on corrosion control pertaining to the BR700 family of engines.
Information published in these documents is considered accurate. However, the information contained in Technical Manuals always takes precedence.
