The global supply chain is causing major disruptions in the private aircraft manufacturing sector. Planemakers are struggling to meet demands for parts, driving up costs for aircraft that are already quite expensive. Private aviation traffic is exceeding 2019 levels, leading suppliers and manufacturers to raise concerns about this issue at a business jet show in Las Vegas this week. Commercial giant Airbus has already noted its concern regarding supply chain issues, while its main competitor Boeing ($BA@US) produces fewer jets than before the pandemic. Meanwhile, planes from Cessna partner Textron ($TXT@US) are flying 20% more than in 2019. Bombardier ($BDRBF@US) stock rose almost 2% in early trading, Lear ($LEA@US) stock rose over 2 and a half percent, and Textron stock rose over 2 and a quarter percent in early trading.
