Core Insights - The aviation industry is expected to face an increase in costs exceeding $11 billion by 2025 due to slow production speeds and supply chain bottlenecks [1][2] - The International Air Transport Association (IATA) highlights that the current supply chain issues are limiting airlines' ability to meet rising passenger demand, with a projected 10.4% increase in demand for 2024 [2][3] Cost Breakdown - Additional fuel costs are projected to account for approximately $4.2 billion, as airlines continue to operate older, less fuel-efficient aircraft due to delays in new aircraft deliveries [1][2] - Extra maintenance costs are estimated at $3.1 billion, driven by the aging fleet requiring more frequent and costly maintenance [2] - Engine leasing costs are expected to rise by $2.6 billion, as longer maintenance periods for aircraft lead to increased engine rentals, with leasing rates having increased by 20% to 30% since 2019 [2] - Inventory holding costs are projected to increase by $1.4 billion due to airlines stocking more spare parts to mitigate supply chain uncertainties [2] Supply Chain Challenges - The backlog of global commercial aircraft orders has reached a historic high of over 17,000 units, significantly above the average backlog of approximately 13,000 units from 2010 to 2019 [1] - The IATA identifies several root causes for the supply chain challenges, including the current economic model of the aviation manufacturing industry, geopolitical instability, raw material shortages, and a tight labor market [2][3] Proposed Solutions - The IATA suggests that opening the aftermarket could provide airlines with more options for parts and services, thereby alleviating some supply chain pressures [3] - Enhancing supply chain transparency is recommended to help airlines plan for bottlenecks and assist original equipment manufacturers (OEMs) in mitigating potential issues [3] - The report advocates for collaborative strategies among all stakeholders in the aviation manufacturing industry to address complex challenges and improve production and maintenance capabilities [4]
