What maintenance action can help identify potential corrosion sources?

Visual inspections are a fundamental maintenance action that plays a crucial role in identifying potential corrosion sources on aircraft. During these inspections, technicians examine various surfaces and components for signs of corrosion, such as discoloration, rust, pitting, or damage to protective coatings. Regular visual inspections can reveal hidden corrosion spots that might not be evident during routine operations, even in areas that are not easily accessible.

These inspections are typically performed at scheduled maintenance intervals or during pre-flight and post-flight checks, depending on the aircraft's operational needs. By identifying corrosion early through visual inspections, maintenance crews can take corrective measures, such as cleaning, repainting, or replacing affected parts, before the corrosion leads to more severe damage that can compromise aircraft safety and performance. This proactive approach is essential for maintaining the integrity and longevity of aircraft components and systems.
