Key Takeaways:

The Modernization of Special Airworthiness Certification (MOSAIC) rule, effective in 2026, replaces aircraft weight and airspeed limitations for sport pilots with performance-based standards, significantly expanding the types of aircraft they can operate, including many common legacy trainers.
While the rule is expected to increase sport pilot training, the aviation community expresses cautious optimism and highlights concerns about the potential shortage of Designated Pilot Examiners (DPEs) authorized for sport pilot check rides and the lower experience requirements for sport pilot instructors compared to traditional CFI certifications.

The impact of the Modernization of Special Airworthiness Certification (MOSAIC) rule is generating a lot of discussion in the aviation community, as many flight schools and education professionals are anticipating 2026 will see more people heading out to the airport to seek sport pilot training.

However, many of us who were instructing in 2004 when the light sport aircraft (LSA) and sport pilot (SP) certificate became a thing are wondering if we’re going to have a “Lucy holds the football for Charlie Brown moment,” as the creation of the LSA/SP rule promised smaller, therefore less expensive airplanes. We heard about the possibility of new trainers that cost less than $100,000, but that did not happen for a variety of reasons—not the least of which were manufacturing and certification expenses.
