What does the symbol (C) indicate on a daily deck inspection?

The symbol (C) on a daily deck inspection signifies that the area is susceptible to corrosion. Corrosion is a significant concern in aviation and marine operations, particularly in areas exposed to the elements, such as saltwater or moisture. By indicating susceptibility to corrosion, this symbol ensures that personnel are aware of the need for regular inspection and preventive measures, such as cleaning and applying protective coatings, to mitigate the effects of corrosion on aircraft and equipment.

Understanding this symbol helps plane captains and maintenance personnel to prioritize their inspections and maintenance efforts effectively, ensuring the longevity and safety of the aircraft. Regular attention to areas marked with this symbol can prevent deterioration that may compromise the performance and safety of the aircraft.
