Plain English Meaning

A written history of everything that has been done to the propeller — when it was installed, when it was inspected, when it was repaired or overhauled, and how many hours it has run.

Full Definition

Permanent maintenance records kept for an aircraft's propeller, documenting its installation, inspections, repairs, overhauls, time in service, and any airworthiness directives or service bulletins complied with. They are separate from the airframe and engine logbooks and travel with the propeller as part of its history.

Context Anchor

Encountered during preflight assessment when a pilot reviews aircraft maintenance records before accepting or flying an airplane.

Derivation

comes from early sea travel, where a ship's and progress were written in a record called a log. In , a logbook is still a running record, but it records the history and required of the aircraft or one of its major parts.
