This podcast an in-depth look at the severe and ongoing supply chain bottlenecks, shortages, and disruptions affecting the aviation maintenance sector, with expectations that these issues will continue into 2025. Data from the International Air Transport Association (IATA) highlights negative trends, including a rising average fleet age, significant shortfalls in new aircraft deliveries, and a record backlog of unfulfilled orders, all of which compromise airline revenues and environmental performance due to less fuel-efficient operations. The podcast also examines the role of aviation asset management companies like AerFin, which are capitalising on the demand for Used Serviceable Material (USM) from strategic teardowns to provide cost-effective and available parts, especially for high-demand engine components and critical Line Replaceable Units (LRUs). Furthermore, it illustrates the financial and operational consequences for airlines through the example of Blue Islands, which faced severe scheduling problems due to delays in maintenance and parts access, and it notes the increasing market values and lease rates for current and new generation engines.
