If the exhaust gas temperature exceeds limitations, what inspection is required?

When exhaust gas temperature exceeds the specified limitations, it indicates that the engine is potentially experiencing issues that could affect its performance and safety. A hot section inspection is necessary in this case because it focuses specifically on the components of the engine that operate at high temperatures, including the combustion chamber, turbine, and exhaust system.

During a hot section inspection, the technician examines these critical areas for signs of wear, damage, or malfunction that might have caused the elevated exhaust gas temperatures. This may involve checking for issues such as excessive carbon buildup, turbine blade deterioration, or any constraints in the exhaust path that could lead to overheating.

In contrast, the other options provided do not directly address the implications of high exhaust gas temperatures. A general engine inspection covers a broader scope and may not specifically target the high-temperature zones. A performance assessment evaluates engine outputs and efficiency but does not examine the physical components. Lastly, a cooling system check, while important for overall engine health, may not directly relate to the immediate concerns raised by elevated exhaust gas temperatures. Therefore, a hot section inspection is warranted to ensure the engine operates safely and efficiently.
