Which statement about Hot Section inspection is true?

Which statement about Hot Section inspection is true?

• A. It is performed on a fixed schedule.
• B. It is on an 'on condition basis' and can use a borescope.
• C. It cannot use borescope.
• D. It is always done separate from other inspections.

Answer: (B)

Hot Section inspection targets the turbine’s hottest components to identify damage that could lead to failure, so timing is driven by the engine’s condition rather than a fixed calendar. Technicians often use a borescope to visually inspect interior areas such as the combustor and first-stage turbine blades and nozzles, checking for cracks, wear, deposits, and heat-related damage without tearing the engine down. Because service history, current condition, and operating data determine when inspection is needed, it’s performed on condition rather than on a set schedule. It isn’t restricted to disassembly only, and it can be coordinated with other maintenance activities, rather than always being done separately. This is why the statement that it is on-condition and can use a borescope is correct.
