The podcast examines the growing use of used serviceable material (USM) in the aviation industry, which is driven by material supply chain challenges and staff shortages lingering after the pandemic. The podcast features interviews with three companies, Vallair, VAS Aero Services, and Optima Aero, which are all involved in the USM market. These companies are using aircraft dismantling and part out to provide spare parts to airlines and MROs, which are struggling to obtain new parts from manufacturers. The podcast also explores the environmental benefits of using USM parts, which can significantly reduce the carbon footprint compared to using new parts.
