What should you expect in the maintenance records for a zero-timed engine?

For a zero-timed engine, the expectation is to find both a new engine logbook and an appropriate entry by the manufacturer. When an engine is zero-timed, it signifies that the engine is essentially treated as a new unit, which requires a new logbook to reflect its current status. This new logbook helps to track all future maintenance and inspections from that point forward.

Additionally, an appropriate entry by the manufacturer is crucial, as it serves to validate the new status of the engine, typically indicating that it has been overhauled, rebuilt, or otherwise brought up to a new condition. This entry is a formal acknowledgment that outlines the work completed on the engine and confirms its operational readiness.

Together, these components ensure that the maintenance records are complete and accurate, thus providing a clear history of the engine's condition and maintenance activity. This is vital for regulatory compliance, operational safety, and for maintaining the value of the engine in the aviation market.
