Is this an exciting time for aviation? Have you been one of the many pilots anticipating Mosaic and the promise it brings for more capable aircraft? The new proposal is loaded with ideas we requested.
As with the SP/LSA rule of nineteen years ago, these features of Mosaic are stimulating all sorts of expectations …but also some worry.
One concern is that new four-seat mLSA with all the bells and whistles will be expensive. Well, they will be — compared to current-day LSA. Yet they will still be half the price of a roughly comparable Part 23-certified aircraft. They will also perform better while using less fuel. Plus, they will be new and nicely equipped with the latest in digital instrumentation.
Contrasting that is an entire fleet of legacy GA airplanes that many pilots have been yearning to fly using a Sport Pilot certificate (or using the no-medical feature of Sport Pilot with their higher FAA ticket).

MOSAIC NEWS — FAA Running Ahead of Schedule? Unbelievable? …Proof Here, Now!
Whenever I write about FAA’s Mosaic regulation, especially when I mentioned the date they predicted, a substantial percentage of all readers shrug this off, believing that FAA will never complete it on time.
What if I told you they were ahead of schedule? Is that an unbelievable claim? Perhaps, but the proof is right here, right now! Can’t wait? Check the link below.
Consider the following communication from the ASTM committee working on LSA standards. In case you don’t know what that is, ASTM is an industry standards group that operates privately, creating and getting agreement on standards used by FAA to accept Light-Sport Aircraft into the aviation fleet. (This is different than conventional FAA “certification.”)
BIG MOSAIC NEWS
Honestly, from almost the beginning, FAA has moved faster than most of us imagined. At EAA AirVenture Oshkosh 2022 FAA announced they would remove the drone portion of Mosaic, which was delaying the overall regulation as that community works out their issues.
Sparker to Ignite Mosaic’s Energy? New and Upgraded mLSA from TL Ultralight
At Aero Friedrichshafen 2023, visitors saw numerous aircraft that could qualify as Mosaic Light-Sport Aircraft or mLSA. In nearly every aisle of the several large halls of Aero, visitors and journalists could see entry after entry apparently made-for-Mosaic. Indeed, so many entries potentially qualify for this coming new segment that I ran out of time to examine all of them.
We are headed into an interesting period of aircraft development and the subject of this article is a perfect example. Welcome to TL Ultralight’s enhanced Sparker.
The model was introduced to the European 600 kilogram (1,320 pound) standard but over the last year it has gone through an extensive evaluation and upgrade to carry a 750 kilogram load (1,653 pounds). It was also revised to accommodate Rotax’s 915iS and 916iS engines.
With greater capacity and with 160 horsepower available, I’d call this a mLSA or Mosaic-ready Light-Sport Aircraft.
After Spring Airshows, Mosaic Questions Emerge — Here’s What We Know Before FAA’s NPRM Is Released
LAMA, the Light Aircraft Manufacturers Association, hosted a gathering of European manufacturers during last month’s Aero Friedrichshafen show. Van’s Aircraft President and Chief Engineer Rian Johnson accepted LAMA’s invitation and presented an update on Mosaic. As the leader of the ASTM committee working on LSA standards, he covered expected changes to help manufacturers prepare.
How can builders design for a regulation they haven’t seen? Thanks to the use of industry consensus standards, the lighter aircraft industry is more aware than you might expect.
Understandably, manufacturer interest is keen; it’s their business. At the same time, individual pilots increasingly raise similar questions.
Top-Four Questions
I’ll address some common inquiries before getting into specifics of the LAMA meeting. The following reflects questions I’ve often heard, along with my responses. As you read these, remember, I am merely one reporter describing discussions I’ve heard. Disclaimer: Information in this article is not official and may not reflect what FAA is planning.
Mosaic-Ready Powerplant… BRP-Rotax Surprises Sun ‘n Fun with a Powerful New Announcement
Sun ‘n Fun 2023 — Day 1
During 2023, in only three months, I’ve lost count how many airframe producers have told me a story that goes something like this…
“We (some manufacturer) offer two 100-horsepower choices: a Rotax 912ULS (carbureted) and 912iS (fuel injected), plus the new 141-horsepower 915iS (fuel injected, intercooled). Yet everyone is ordering the 915.” More power always draws interest.
As you read yesterday, BRP-Rotax has bumped up the juice on the 912iS. Paul Mather of M-Square reported, “Rotax’s latest 912iS now offers 105 horsepower.”
This increase is not particularly unusual. BRP-Rotax has long been quite conservative with their initial numbers. Before 915iS was ready for market, the Austrian manufacturer said to expect 135 horsepower. It turned out to test at 141 continuous horsepower, a 4% increase.
And Now…!
Rotax’s newest 916iS
At their Sun ‘n Fun 2023 press conference, Rotax said, “We are proud to achieve a new level of performance with the launch of our Rotax 916iS/c aircraft propulsion system, which makes it perfectly suitable for four seater planes and for high performance two seaters.” Float-equipped airplanes may embrace the more potent engine as an aid to break water faster.
6 Mosaic High Wing Light-Sport Aircraft — FAA’s Coming Rule Will Create “mLSA” Sector
Darkest before dawn? I hear growing concern about FAA’s new Mosaic regulation and what it will or won’t do. An increasing number of comments I hear are variations of these words — “FAA is never going to get this done, and if they do, it will be a crappy rule.”
Why so glum?
Maybe pilots are frustrated because FAA has delayed the release of Mosaic. This also happened almost 20 years ago with the Sport Pilot / Light-Sport Aircraft regulation. SP/LSA was anticipated for more than three years after the first announcement.
However, Mosaic is coming and this time we know more about it than most regulations. Why? Because FAA must involve ASTM committee members along the way. (More on this? See at end.*)
Earlier FAA rule writers did not reveal their work as broadly. Yet FAA is sufficiently pleased with industry consensus standards, ASTM’s work, that they will use it on the next generation of GA aircraft (think: Cessna, Cirrus, etc.).
Aero Showcase — Day Two: Was This the First Mosaic LSA Show?
As I departed DeLand airport on Saturday at the close of Aero Showcase 2022, I recalled multiple conversations with attendees regarding the airplanes on display. Over and over I was asked if one of the displayed aircraft could benefit from a higher weight under Mosaic rules.
The short answer, I told them, is yes. A good many LSA were initially designed and subsequently tested to higher weights than the 1,320 pounds permitted under present FAA rules. What will happen to these 1,320-pound LSA when higher weight Mosaic LSA come out, some asked? Will these current LSA become obsolete?
I believe they will not, because any LSA you buy today will work just as well under Mosaic. It may not carry as much or have some other attribute, but neither will current LSA cost more as will larger and better equipped Mosaic LSA.
However, many — perhaps a third, maybe half — of all LSA on the market today have actually been constructed and tested to carry somewhat higher weights.
Midwest LSA Expo 2022 Presentation — What We Know about FAA’s Mosaic Regulation, with Q&A Session
I am honored that the room was full to standing room only capacity but even that gratifying turn-out at the Midwest LSA Expo 2022 represents a fraction of pilots keen to learn more about Mosaic. I refer to a forum at the event, a talk that has been well attended since I began attempting to keep up with FAA’s latest moves on the new LSA regulation.
For the majority that could not attend in person, the entire talk is featured below. In particular, I think you may enjoy the Question & Answer portion starting at 32 minutes into the video. See the list of questions below for specific times — in case you know most of this but simply wanted to ask a certain question.
I’ve been predicting for months that if FAA was to stay on schedule — a schedule they set — the agency had to announce Mosaic at Oshkosh 2022.
While FAA Reworks Mosaic, Other Nations Are Moving Ahead — Is USA Falling Behind?
Capitalism and competition are one thing. Government policies and actions are quite another. You already know this.
Sometimes, however, these two seemingly-opposite concepts aren’t so different. What does this have to do with Light-Sport Aircraft?
American pilots, like aviators in other countries, must obey regulations in the nation where they operate their airplanes. Yet the same requirement is not necessarily true for those who produce the airplanes we enjoy. Producers, it turns out, have choices.
Under an arrangement called reciprocity, manufacturers in certain nations (Note 1; see at bottom) can meet their local regulations and FAA will then accept such aircraft without them going through the American certification system. What results is a form of competition between government regulatory agencies.
European builders may be early users and beneficiaries but American companies could use reciprocity as well.
Readers may remember that when Cessna was still promoting their ill-fated Skycatcher SLSA, they considered pursuing 1990’s-era Primary Category.
FAA’s Mosaic Rule — Delayed (a Year or More); Further Information about the New LSA Regulation
One of the most-read articles from my coverage of EAA AirVenture Oshkosh 2022 was the news that FAA missed their deadline as originally projected and will be a year or more late with the Mosaic rule. Many were upset at that result; others thought it was “par for the course.”
The good news, as I reported in the article, is that what emerges in one year will be a regulation that might actually go forward. Let me explain a little more fully.
During Oshkosh 2022, I attended three meetings where FAA spoke. I also had one-on-one discussions with several knowledgeable people. What follows is a fusion of all those conversations. While I believe this information to be accurate, the situation is changing and more questions will arise. Please consider this a snapshot in time.
The Main Question — As some commenters to the earlier article said, FAA did specify a date when the Mosaic NPRM may be released: “August 2023.” This came directly from David Boulter who was selected by the FAA Administrator to answer an audience question; the comment was made in a public forum.
