The FAA Aerospace forecast that the U.S. mainline jet fleet will grow from 4,832 in 2023 to 6,894 by 2044 indicating that the push towards aftermarket services is probably growing as well.
  

Aircraft Aftermarket Parts Market Trends

• key trend in the aircraft aftermarket parts industry is predictive maintenance using AI and data analytics, which started gaining traction around the mid-2010s. This trend is accelerating because it allows airlines to predict component failures, minimize unexpected down time, and optimize maintenance schedules. The prediction maintenance trend has been facilitated by the growth of the IoT and big data, and is growing rapidly in adoption, with further growth expected at its peak in early to mid-2020s, as airlines continue to promote efficiency and minimize costs. For instance, the U.S. Department of Defense (DoD) in the Fiscal Year 2024 budget request proposed USD 1.8 billion on artificial intelligence initiatives for which predictive maintenance technologies could be included.
  
• The rapid growth of the aircraft aftermarket parts market, driven by rising global air travel and increased demand for maintenance, repair, and overhaul (MRO) services, is a key trend. This highlights the essential role of parts supply and advanced servicing in ensuring aviation operational reliability. This trend began from the early 2010s onwards when airline fleets were increasing and their fleets were aging. Airlines are exploring aftermarket solutions and products to accrue the aircraft availability and decrease their operational costs. The peak of this market to occur in the 2030s, as fleets continue to grow and complexities arise in providing the timely and efficient replacements of parts to ensure safe operations. According to ACI World and ICAO, global passenger traffic will reach 9.5 billion in 2024, exceeding pre-pandemic levels, and by 2042 will surpass 19.5 billion, twice that of 2024.
