Which statement about Cold Section inspection is true?

• A. It is performed on a fixed schedule and cannot use a borescope.
• B. It is on an 'on condition basis' and can use a borescope.
• C. It requires no inspection after engine start.
• D. It is never performed in field.

Answer: (B)

Cold Section inspection checks non-rotating engine parts while the engine is shut down, looking for wear, damage, or other signs of deterioration in areas like the compressor and surrounding hardware. It is performed on an on-condition basis, meaning the need for inspection is driven by condition, usage, and maintenance history rather than a fixed calendar. A borescope is a common and practical tool for this inspection, allowing a detailed visual check through access ports without taking the engine apart. Because it’s adaptable and can be done with portable equipment, this inspection is routinely performed in the field when needed. The idea that it’s on a fixed schedule, cannot use a borescope, or is never done in the field doesn’t fit with how cold section checks are actually conducted.
