When are special inspections typically conducted?

Special inspections are typically conducted during adverse weather or aircraft incidents because these conditions can significantly impact airport operations and safety. Adverse weather, such as heavy rains, snow, or strong winds, may require specific evaluations of the airport infrastructure and equipment to ensure they are functioning correctly and safely. Similarly, aircraft incidents necessitate thorough inspections to assess any potential damage, hazards, or safety concerns that might affect subsequent operations. These inspections are crucial for maintaining safety standards and compliance with regulations during conditions that deviate from normal operations.

The other options suggest regular or routine inspection schedules, which may not adequately address the urgent need for special inspections prompted by unexpected or emergency circumstances. Regularly scheduled inspections serve a different purpose compared to the urgent nature of special inspections that arise from specific incidents or severe weather challenges.
