Key Takeaways:

The MOSAIC (Modernization of Special Airworthiness Certification) proposal significantly expands Light Sport Aircraft (LSA) capabilities, removing weight limits (allowing up to 3,000 lbs), increasing stall speed, permitting four seats, retractable gear, adjustable props, higher speeds, and incorporating new propulsion types (electric, turbine) and aircraft categories (helicopters, gyroplanes).
While granting extensive aircraft upgrades, the proposed rule introduces several concerns and inconsistencies, particularly regarding pilot privileges, such as conflicting medical requirements for sport pilots flying at night or IFR, and new noise regulations seen as an unnecessary burden.
Additional issues include potential impacts on LSA owner maintenance privileges, challenges for mechanic training on new technologies, and a general perception of the NPRM being "rushed," leading to an extended comment period for stakeholders to address ambiguities.

MOSAIC (Modernization of Special Airworthiness Certification) is a regulation that affects all aircraft with special airworthiness certificates. Aircraft built by Cessna, Piper, Cirrus, Diamond, and others instead have standard certificates, and their new models remain untouched by this proposed regulation.

In contrast, all light sport aircraft (LSA), experimental amateur-built airplanes, and warbirds are issued special certificates. In my view, the rule can be divided into two main parts: airplane descriptions and capabilities, and pilot certificates, technician privileges, and operating limitations. In short, airplanes or people.
