In this episode of the Aviation News Talk podcast, Max Trescott talks with Sean Elliott, Vice President of Advocacy and Safety at the Experimental Aircraft Association (EAA), about the FAA's groundbreaking MOSAIC final rule—and how it benefits all pilots, not just sport pilots or Light-Sport Aircraft owners.
Sean explains that MOSAIC replaces the old, restrictive Light-Sport Aircraft definition with a performance-based standard, removing the long-standing 1,320-pound maximum takeoff weight limit and focusing instead on a clean stall speed (VS1) of no more than 59 knots CAS for sport pilot privileges and a landing configuration stall speed (VSO) of no more than 61 knots for LSA certification. This single change dramatically broadens the pool of aircraft that qualify, meaning many popular legacy models—like certain Cessna 172s and even Cirrus SR20s—can now be flown by sport pilots, and private pilots can operate them under sport pilot privileges with nothing more than a valid U.S. driver's license in place of an FAA medical.
For older pilots or those with long-term medical concerns, MOSAIC is a game-changer. A private pilot who no longer maintains a Third Class or BasicMed medical can still keep flying a wide variety of capable, familiar aircraft—often including the same ones they've flown for years—so long as they meet the new stall speed limits and carry no more than one passenger. Sean and Max discuss how this provision gives seasoned aviators a safe and legal way to extend their flying years without the administrative burden or risk of renewing a medical certificate.
MOSAIC also expands sport pilot privileges beyond the original daytime, fair-weather limitations. With additional training and endorsements, sport pilots will be able to fly at night under VFR, operate aircraft with constant-speed propellers and retractable landing gear, and take advantage of higher cruise speeds—removing many of the practical barriers that once kept sport pilots from flying more capable airplanes. The rule even opens the door for certain limited commercial operations by sport pilots, including banner towing, glider towing, and pipeline or powerline patrol—tasks previously off-limits without at least a private pilot certificate.
On the aircraft side, the MOSAIC framework allows manufacturers to certify a much wider range of designs as LSAs under ASTM consensus standards. This could lead to modernized versions of classic Part 23 trainers like the Cessna 172 becoming available in factory-new LSA configurations, as well as innovative new designs in the experimental, gyroplane, and electric aircraft categories. Sean notes that this flexibility benefits the industry by encouraging innovation while keeping costs lower than traditional FAA certification pathways.
Flight schools stand to gain as well. Because many mainstream trainers now qualify as LSAs, schools can use them to train sport pilots without investing in specialized two-seat LSAs that may be less versatile for other types of training. This flexibility could help schools reach a new segment of students—especially older adults returning to flying or beginners looking for a faster, less expensive path to the cockpit.
Max and Sean also cover how MOSAIC affects aircraft maintenance. Repairman certificates for LSAs will still exist, and MOSAIC provides expanded privileges for light-sport repairman-inspectors and mechanics working on these aircraft, supporting both owner-maintenance and professional servicing.
Sean stresses that while MOSAIC dramatically broadens options, it doesn't automatically change the certification status of existing aircraft—manufacturers or owners must still pursue LSA certification through the ASTM process. That means pilots should verify whether a particular aircraft is LSA-certified or qualifies for operation under sport pilot rules before assuming they can fly it without a medical.
The conversation closes with EAA's commitment to supporting pilots, flight schools, and manufacturers through MOSAIC's rollout. EAA will work closely with ASTM to develop the updated industry standards needed to implement the new rules, while also providing education and advocacy to ensure pilots understand their new privileges and responsibilities.
This episode is essential listening for any pilot curious about the future of general aviation under MOSAIC—whether you're a sport pilot, a private pilot considering BasicMed alternatives, a CFI planning to expand your student base, or an aircraft owner wondering if your plane might now qualify as an LSA. With expert insights from one of the country's leading aviation advocates, you'll learn exactly how MOSAIC changes the game for who can fly what, and under what conditions, for years to come.
