AOG, Rotables & Spare-Parts Supply

This cluster is the parts-and-logistics backbone that keeps maintenance moving: distribution of new, overhauled and surplus aircraft parts, rotable exchange, AOG desks that source a needed part anywhere in the world within hours, consignment and pooling stock, and fleet tear-down / parts-harvesting from retired airframes. It overlaps with maintenance because the same firms often run repair networks, but the buyer intent is procurement of a physical part, not a labour service. Providers range from global parts integrators with procurement platforms to regional rotable traders. Buyers are airline procurement, MRO providers and lessors sourcing material to close a maintenance task or recover a grounded aircraft.
