In today’s highly competitive and cost-sensitive aviation environment, airlines are under constant pressure to reduce maintenance expenses without compromising safety or performance. One of the most effective strategies gaining traction across the industry is the use of Used Serviceable Material (USM). But what exactly is USM, and why are more airlines incorporating it into their maintenance programs?
Understanding USM in Aviation
Used Serviceable Material (USM) refers to aircraft components that have been removed from in-service aircraft, inspected, tested, and certified as airworthy according to stringent industry and regulatory standards. These parts can include everything from landing gear and APUs to avionics and flight controls.
