When should engine inspections be conducted more frequently than the standard intervals?

Conducting engine inspections more frequently than the standard intervals is particularly important when the engine operates under harsh conditions. Harsh operating environments can include extreme temperatures, heavy loads, high humidity, or exposure to corrosive substances, all of which can accelerate wear and tear on engine components. By increasing the frequency of inspections in these scenarios, it allows for the early detection of potential issues that could lead to engine failures, thus enhancing safety and reliability.

While other factors like indications of potential failure and operational hours exceeding limits are valid reasons for more frequent inspections, harsh operating conditions are a pervasive issue that affects the overall integrity and performance of the engine. Furthermore, incomplete maintenance records might indicate a lack of information regarding previous inspections, but this alone doesn't necessitate more frequent inspections unless linked to harsh conditions or other risk factors.
