How does overhauling an engine affect its total time?

When an engine is overhauled, it involves a comprehensive inspection, repair, and replacement of components to return it to a condition that meets or exceeds its original specifications. While the act of overhauling may not change the actual runtime of the engine logged in its total time, it is essential for this work to be meticulously documented in the engine’s records.

The logging of the overhaul in the records is crucial for maintaining the engine’s maintenance history, which is necessary for regulatory compliance and ensuring the engine remains eligible for continued airworthiness. The total time is a key metric for airlines and operators, affecting maintenance schedules, operational limitations, and resale values, and, therefore, must reflect any significant work done like overhauls. This means that complete and accurate documentation of the overhaul appended to the engine's history is required, which gives a clear account of the work performed and its implications for future inspections and operations.

The other options do not accurately represent the impact or requirements associated with an engine overhaul. Resetting the total time to zero would misrepresent the lifespan of the engine and could lead to safety concerns, while the notion that an overhaul does not affect total time overlooks the importance of accurate maintenance record-keeping.
