One of the biggest challenges aircraft operators face is the occurrence of corrosion in different forms and other areas, often not discovered until the aircraft goes in for base maintenance. Corrosion prevention is very challenging work; it is nearly impossible because corrosion is the natural phenomenon of metals.
While manufacturers take all possible measures during the design and manufacturing phases to prevent corrosion occurrences on their aircraft structures, engines, and associated components, the availability of electrolytes in different forms (atmosphere, dart deposits, moisture trap at crevices, etc.) is critical factors in the progression of the corrosion phenomenon. Hence, protecting base metals from electrolytes can help us to a great extent in preventing the occurrence of corrosion.
Corrosion Prevention & Control Programs (CPCP)
Most aircraft manufacturers have well-defined Corrosion Prevention & Control Programs (CPCP). Many aircraft and parts, including engine casings, mounts, and so on, encounter severe corrosion issues. Corrosion not only makes an aircraft un-airworthy, compromising flight safety, but operators can also incur huge unplanned costs during base and major maintenance tasks. Most importantly, the corrosion problem is not covered by the manufacturer, insurance companies, or even maintenance companies.
The Shared Responsibility for Corrosion Prevention
Technically, Corrosion Prevention is a tri-party responsibility Manufacturer, Maintenance Company, and Operator.
- Manufacturer’s Role: The Manufacturer takes all measures during the design phase & manufacturing process and issues CPCP and other advisories to prevent corrosion.
- Maintenance Agency’s Role: Maintenance agencies follow the manufacturer’s guidelines to ensure preventive measures are implemented.
- Operator’s Role: Ultimately, the operator ensures the aircraft is airworthy. This responsibility is a moral obligation and a legal one under Civil Aviation Regulations.
Proactive Maintenance Practices
Proactive and good maintenance practices, such as
- External Surface Cleaning
- Paint Protections
- Corrosion Inhibitor Compounds (CICs)
can help minimize the corrosion occurrence on aircraft & parts to a greater extent.
