Let me do the obvious first. Mosaic has for some weeks been in what agency personnel call their “quiet period.” This is when FAA is finalizing a regulation and will no longer respond to info requests. Public comment windows are long closed.
Short take — We know only a little more than we did a few months back. Major questions remain about what license level of pilot can fly what configuration of Mosaic LSA using what medical. We have no new information on these questions. In addition, many in the LSR-M mechanic community also have many questions and concerns.
The public had a chance to comment, and lots of you did. Now, after reading every single comment, FAA rule writers are head down preparing the final version
Coming in Mid-205
Word from those who talk to FAA about other matters say the Mosaic reg is proceeding well. It is expected by “mid-2025,” though such pronouncements have often proved premature. However, since FAA has been timely with previous forecasts about Mosaic, perhaps by AirVenture 2025 (starting in late July), we will have the new rule to examine.
Finally, we will learn the answers to many questions.
Of course, all this is expected as Trump takes office next month. With his push to eliminate 10 regulations for every new one, federal rule makers may exercise added caution so as not to get in trouble with the new boss — and I don’t mean yet another new FAA administrator… I mean POTUS.
The following chart was assembled by longtime industry leader Paul Hamilton, proprietor of the Sport Aviation Center. In addition to being a flight instructor and Designated Pilot Examiner, Paul has also developed video-based courses to study for Sport Pilot licensing and more. He is a good candidate to create the information shown below.
This is about as easy to study as any literature I’ve seen.
Happy Christmastime reading!

Dan – that you for your continuing superb updates on MOSAIC. Assuming the final rule is published in July, would it likely be effective immediately or have an effective date later in the year? ~John
Assuming previous patterns, and assuming that the rule revisions are as far along as I have been told, I suspect FAA will make a grand announcement at AirVenture 2025 and the rule could be effective by September 1, 2025. It is further my expectation that leading aircraft producers will be ready with Mosaic LSA models or current LSA models with specs increased as allowed (and as their testing has confirmed). Thanks for your kind words.
Didn’t our President elect learn anything last time? His order then was to eliminate 2 rules for every new one passed. All that that did was make the agencies roll the old rules into the new one, thus creating long complex rules that were more burdensome than the ones before them. Now he wants to eliminate 10 rules for each new one? Insanity.
I have a terrible feeling that under this new administration MOSAIC will never come to be. Just my opinion.
