An AOG spare parts warehouse (AOG: Aircraft on Ground) is a certified inventory facility that holds aviation components ready for immediate dispatch whenever an aircraft is grounded due to a technical defect. Every hour an aircraft sits idle translates into significant losses for the airline—missed revenue, passenger compensation, and missed slot times. To minimize downtime, these facilities are pre-positioned at major aviation hubs worldwide and operate around the clock with response windows measured in hours. Freight forwarders handle AOG shipments via priority air freight, expedited customs clearance, and real-time tracking. Unlike standard spare parts depots, AOG warehouses must comply with strict regulatory requirements from aviation authorities such as EASA or the FAA regarding storage conditions, traceability, and documentation.
