What is the maintenance check called that assesses engine performance?

The maintenance check that assesses engine performance is referred to as an engine performance inspection. This inspection focuses specifically on evaluating how an engine operates under various conditions, measuring parameters such as thrust output, fuel efficiency, and overall operational stability. It involves a detailed analysis of engine performance data, ensuring that the engine is functioning within its specified limits and standards.

The engine performance inspection is critical for maintaining safety, efficiency, and reliability in aviation. Regular assessments help identify potential issues before they become serious problems, allowing for proactive maintenance and reducing the risk of engine failure during flight.

This inspection differs from other checks that may assess different aspects of the engine or maintenance process, such as the engine condition survey, which might focus on the physical state of the engine components, or the engine reliability test, which evaluates how consistently an engine performs over time. The engine range examination is not a standard term widely recognized in aviation maintenance.
