Rotable
A rotable is an aircraft part that can be repeatedly removed, overhauled, and returned to service, such as landing gear, hydraulic pumps, or avionics units. Rotables carry a serial number and a full service history, and they hold most of the value in an aftermarket inventory. They contrast with expendables, which are replaced rather than repaired, and consumables like seals or fasteners, which are used up in a single installation.
