Business Aviation remained relatively flat in 2024, as the industry has generally been since the Great Recession 2008. The industry is unlikely to recover to near those record levels in the foreseeable future. Examining the data for the 4th quarter of 2024, warning signs are on the horizon, as shipments of single-engine piston and electric, twin-engine piston, single-engine turboprops, multi-engine turboprops, and business jets all fell during the fourth quarter of 2024 when compared with 2023.  Typically, aviation is a bellwether, and that doesn’t bode well for the economy as a whole.
