Wheel wells and landing gear are areas requiring extra attention for corrosion checks.

• A. Fuel tanks
• B. External skin
• C. Wheel wells and landing gear
• D. Piano hinges

Answer: (C)

Moisture retention and restricted access make wheel wells and landing gear especially vulnerable to corrosion. These bays trap water, salt, mud, and de-icing fluids, and limited drainage or ventilation means that contaminants can linger and initiate corrosion on hidden surfaces, fasteners, and seams. The landing gear is repeatedly exposed to moisture, hydraulic fluids, lubricants, and environmental debris, while the mechanical cycling and contact between dissimilar metals can accelerate galvanic corrosion. Because these areas are not easily visible or reachable during routine inspections, corrosion can start in hidden pockets and progress before it’s noticed. That combination of environmental exposure, potential fluid leakage, and inspection difficulty is why extra attention is required for corrosion checks in these zones. Other areas can corrode too, but wheel wells and landing gear pose a higher risk due to moisture retention, contaminants, and access challenges.
