Definition
An aircraft engine that has been completely disassembled, inspected, and rebuilt by the original manufacturer (or a manufacturer-approved facility) to the same tolerances and specifications as a new engine. Worn or out-of-limit parts are replaced with new or serviceable parts, and the engine is issued a new logbook with zero time since new (zero-timed). Only the original manufacturer is permitted to issue a remanufactured engine with zero-time status.
Plain English
An engine that has been taken apart, restored to factory-new condition by the company that built it, and given a fresh logbook that starts the time count over at zero.
Context Anchor
Seen in aircraft maintenance records, engine logbooks, sales listings, and discussions about engine replacement options.
Derivation
From the prefix 're-' (again) plus 'manufactured' (made). Literally means 'made again.' The word itself signals that the engine has gone back through a manufacturing process, not just a repair process — which is why a fresh, zero-time logbook is permitted.
Why Pilots Care
A remanufactured engine usually provides higher reliability assurance and better resale value than a standard field overhaul.
Intuition Check
Do not assume remanufactured simply means “used” or “recently repaired.” In this context, it means the engine was taken apart and built back up to an approved new-engine-type standard, with records to show that work.
Example Sentence 1
When the engine reached the end of its service life, the owner chose to install a remanufactured engine from the factory rather than have the existing one overhauled.
Example Sentence 2
The prebuy inspection showed the engine had been remanufactured by a factory-approved facility two years earlier.
