MOSAIC Briefhttps://faamosaic.com/ Clear guidance for the next chapter of recreational aviation.en-us editor@faamosaic.com (Av8r Capital Group Corp) MOSAIC is in effect: what changed, who it affects, and which date applieshttps://faamosaic.com/articles/mosaic-in-effect-start-here/https://faamosaic.com/articles/mosaic-in-effect-start-here/Tue, 13 Oct 2026 05:09:24 GMTMOSAIC is the FAA’s 2025 rule on special airworthiness certification. Here is what it changes for pilots, owners, builders, manufacturers and maintenance providers, how its dates differ, and where to go next, as of October 12, 2026. Sport pilot night flying: what you need besides an endorsementhttps://faamosaic.com/articles/sport-pilot-night-flying-requirements/https://faamosaic.com/articles/sport-pilot-night-flying-requirements/Tue, 13 Oct 2026 05:09:24 GMTNight privileges under 14 CFR 61.329 take category-and-class night training, a medical basis beyond a driver’s license and an instructor endorsement, and the aircraft’s own limitations must also permit night flight. Retractable gear and manual controllable-pitch propellers: what a sport pilot needshttps://faamosaic.com/articles/sport-pilot-retractable-gear-propeller-endorsements/https://faamosaic.com/articles/sport-pilot-retractable-gear-propeller-endorsements/Tue, 13 Oct 2026 05:09:24 GMTUnder 14 CFR 61.331, a sport pilot needs training and an instructor endorsement for retractable gear and, separately, for a manual controllable-pitch propeller. The water-aircraft exception covers retractable gear only. “Kit” doesn’t tell you which kind of airplane you’re buildinghttps://faamosaic.com/articles/kit-built-eab-versus-light-sport-kit/https://faamosaic.com/articles/kit-built-eab-versus-light-sport-kit/Tue, 13 Oct 2026 05:09:24 GMTTwo kit airplanes can follow different FAA certification routes. Here is how amateur-built and light-sport kit-built aircraft differ, what the FAA’s “51-percent rule” means, and what to ask before you buy. Who can sign an E-AB condition inspection? Light-sport repairmen, builders and mechanicshttps://faamosaic.com/articles/light-sport-repairman-eab-condition-inspections/https://faamosaic.com/articles/light-sport-repairman-eab-condition-inspections/Tue, 13 Oct 2026 05:09:24 GMTA light-sport repairman can inspect an amateur-built aircraft only if the certificate, rating, ownership and the aircraft's own operating limitations all line up. Here is how builder and light-sport repairmen differ. Safety directive or airworthiness directive? What a light-sport owner must do with eachhttps://faamosaic.com/articles/light-sport-safety-directives-airworthiness-directives/https://faamosaic.com/articles/light-sport-safety-directives-airworthiness-directives/Tue, 13 Oct 2026 05:09:24 GMTA manufacturer’s safety directive and an FAA airworthiness directive carry different legal weight. Here is who issues each, which one is mandatory, and why you still have to keep the aircraft airworthy. Where to find the FAA's accepted MOSAIC consensus standards, and what the list meanshttps://faamosaic.com/articles/faa-mosaic-consensus-standards-directory/https://faamosaic.com/articles/faa-mosaic-consensus-standards-directory/Tue, 13 Oct 2026 05:09:24 GMTThe FAA's light-sport category aircraft page lists the accepted Part 22 consensus standards. Here is what they are, how to read the two lists, and why a page date is not an acceptance date. Sport pilot checkrides and the new “B” test standards: what to ask before you schedulehttps://faamosaic.com/articles/sport-pilot-pts-october-14-2026-compliance/https://faamosaic.com/articles/sport-pilot-pts-october-14-2026-compliance/Tue, 13 Oct 2026 05:09:24 GMTThe FAA’s updated sport pilot practical test standards took effect September 14, 2026, with a separate October 14, 2026 compliance date. Here is what a PTS is, what changed, and what to confirm with your examiner. “MOSAIC ready” is not a certification basis: what a statement of compliance tells youhttps://faamosaic.com/articles/light-sport-manufacturer-statement-of-compliance/https://faamosaic.com/articles/light-sport-manufacturer-statement-of-compliance/Tue, 13 Oct 2026 05:09:24 GMTCalling an aircraft “MOSAIC ready” does not establish how it was certificated. For a new light-sport aircraft or kit, ask for the manufacturer’s statement of compliance and the standards behind it; other routes need their own documents. “Sport pilot legal” is not the same as “light-sport aircraft”https://faamosaic.com/articles/sport-pilot-aircraft-eligibility-vs-certification/https://faamosaic.com/articles/sport-pilot-aircraft-eligibility-vs-certification/Tue, 13 Oct 2026 05:09:24 GMTWhether a sport pilot may fly an aircraft (14 CFR 61.316) is a different question from how the aircraft is certificated (21.190, Part 22). A four-seat airplane can be eligible without being light-sport category, and privileges do not grow with seats. What counts as an ultralight vehicle under FAA Part 103https://faamosaic.com/articles/what-counts-as-an-ultralight-vehicle-faa-part-103/https://faamosaic.com/articles/what-counts-as-an-ultralight-vehicle-faa-part-103/Tue, 13 Oct 2026 05:09:24 GMTSection 103.1 defines an ultralight vehicle: one occupant, recreation or sport only, no airworthiness certificate, plus weight limits and, if powered, fuel, speed and stall limits. Here is what that means, including fuel capacity versus fuel carried.
