What type of inspections are required for the ERJ's landing gear?

The correct choice emphasizes the comprehensive approach needed for ensuring the safety and functionality of the ERJ's landing gear. Visual checks are essential to identify any obvious signs of wear, damage, or corrosion on the landing gear components. These visual inspections help detect issues that might not affect functionality immediately but can compromise safety over time.

Functional tests complement the visual checks by verifying that the landing gear operates correctly under real conditions. This includes testing the retraction and extension mechanisms and the hydraulic systems involved in landing gear operation. Both types of inspections are crucial; visual checks detect potential issues before they become serious, and functional tests confirm that everything operates as intended during actual use.

This integrated method of inspection helps maintain the aircraft’s operational safety and compliance with aviation regulations, ensuring that both the condition and operation of the landing gear are thoroughly assessed.
