Components and Line Replaceable Units

Aircraft components and LRUs from Satair

Line Replaceable Units (LRU) are modular components and usually sealed units of an aircraft, which are designed to be replaced within a short time without using very specialized tools. This means that the aircraft can quickly return to service, while the failed LRU is being tested and repaired.

A Line Maintenance Part (LMP) is a sub-component of an LRU, which may be replaced without removing the LRU from the aircraft. Depending on its complexity, an LMP can be repairable or expendable. A list of applicable LMPs can be found in the Recommended Spare Parts List (RSPL).
