How often should aircraft be subjected to corrosion inspections?

Aircraft should be subjected to corrosion inspections frequently, in accordance with maintenance schedules and taking into account environmental conditions. Corrosion can be influenced by various external factors, including humidity, temperature, and exposure to salt or chemicals, which can vary significantly based on where and how the aircraft is used.

Regular inspections help in identifying early signs of corrosion, allowing for timely remediation before it leads to more significant damage that could compromise the safety and structural integrity of the aircraft. Maintenance schedules are established based on manufacturer guidelines, regulatory requirements, and operational experience to ensure that inspections occur at appropriate intervals.

By adhering to these guidelines, crews can help extend the lifespan of the aircraft and maintain its airworthiness. This proactive approach is necessary because corrosion can develop unnoticed over time, especially in hard-to-reach areas. Regular and frequent inspections are therefore essential rather than relying on less frequent or event-based checks, which may not adequately ensure the aircraft's integrity.
