Rebuilt Aircraft Engines are used engines that has been completely disassembled, inspected, repaired as necessary, reassembled, tested, and returned to service in the same manner and to the same tolerances and limits as a new engine with either new or used parts.

Jet engines in use on today’s commercial airliners are quite reliable. It is not uncommon for engines to operate for tens of thousands of hours without difficulty before being removed from service for scheduled inspection. However, engine malfunctions or failures occasionally occur that require an engine to be shut down in flight. Since multi-engine airplanes [...]

An “uncontained” engine failure is a failure where rotating elements of the engine penetrate the case of the engine. This type of failure can be very serious because pieces from the engine exit the engine at high speeds in directions other than the normal exhaust path , posing potential danger to the aircraft structure and [...]

A “contained” engine failure is one in which components might separate inside the engine but either remain within the engine’s cases or exit the engine through the tail pipe. This is a design feature of all engines and generally should not pose an immediate flight risk.
