Mosaic was a subject of intense conversations at AirVenture Oshkosh 2023. In a surprise to many of us, FAA released the Notice of Proposed Rule Making (NPRM) for Mosaic ahead of schedule. Lots of people who needed to study it were already en route to the EAA show for a week, 10 days, or more.
If you haven’t been paying attention, MOSAIC is an acronym for a regulation that affects all aircraft with Special airworthiness certificates. Aircraft built by Cessna, Piper, Cirrus, Diamond, and others instead have Standard certificates and are not touched by this Mosaic regulation. In contrast, all LSA, Experimental Amateur Built airplanes, and warbirds have Special certificates. (FYI, I stopped writing Mosaic in all-caps because it looks like shouting.)

The Clock Is Ticking…
FAA offered 90 days to comment on their proposal that started out as 318 pages of text that no one would call fun reading.
