Rotable Exchange, Component Pooling & Inventory Management

Rather than buying a part outright, operators increasingly access rotable line-replaceable units (LRUs) through exchange, pooling, loan and consignment programmes managed by asset and component-management houses. The provider owns and manages a shared pool of overhauled rotables, swaps a serviceable unit for the operator's removed unit, manages the repair loop and certification, and bills per-event or per-flight-hour. The buyer's decision turns on pool coverage for the fleet type, guaranteed turn time, certification on every exchange and total-cost-of-ownership versus owned stock. Distinct from outright trading (USM/new) because the transaction is access-and-return, not purchase, and tightly coupled to repair-management of the returned core.
