The two hosts explore the growing importance of used serviceable material (USM) in the aviation industry. The first host focuses on how Maintenance, Repair and Overhaul (MRO) information technology systems are helping airlines and MROs comply with safety regulations. The second host examines the challenges of maintaining aircraft and helicopters in a post-pandemic world where supply chain issues and staff shortages persist, leading to increased demand for USM. The podcast features interviews with key players in the USM industry, including Vallair, VAS Aero Services and Optima Aero, who discuss their strategies for sourcing and supplying USM parts, as well as the growing emphasis on sustainability and carbon footprint reduction.
