I would think a Sling TSI, that I don't have to build, might fall into this sweet spot. I suspect that might be in the $400 to $500k range though.
I always thought this subject was interesting. Unviable due to up front costs, or unviable because no or limited ROI on those costs? As to legacy Part 23 costs this was known prior to the launch of LSA in 2004 and partly was the reason behind the FAA LSA move. So afterwards, they went forward with a complete rewrite of Part 23 where over 1000 prescriptive regulations were deleted and replaced by consensus standards listed in various Advisory Circulars to address those costs.It is economically unviable to bring useful new personal aircraft to market. LSA aircraft are too small, too slow, and too squirrely. Part 23 certification requirements are cost prohibitive.

Except rules do not define risk. Market does. For example, one of the new Part 23 aircraft I mentioned above took the risk on a new single turbine (and engine) whose sole market only covers about a 2000 aircraft fleet that took 30 years to build. What did the OEM see in that small defined market that they didn't see in the Part 91 private, rec market with a fleet numbering in the tens of thousands?Hopefully the new rules lower the perceived financial risk of bringing new designs to market.
No. But I see eVTOLs having an impact on MOSAIC.Do you see MOSAIC having an impact on eVTOL?
Not that I’ve seen or read. eVTOLs were barely a NASA prototype at that time. But if you dig deep into the origins of the Certification Process Study/Aviation Rulemaking Committee for the Part 23 rewrite you find discussions on a Primary Non-Commercial aircraft category. If anything, IMO, it was the P-NC discussion that was the impetus to MOSAIC.I was under the impression that was part of the impetus.
OK, but will that drop the price from $400k to $100k?What I mean is: there is nothing stopping Cessna from from killing the old part 23 172 and releasing a "172.5" that conforms to ASTM and MOSAIC post July 2026. I think you'll see Cessna, Cirrus, Van's, and other "legacy" manufacturers do this. It just makes sense for the deregulatory reasons when it comes to the airframe and maintenance alone.
I am kinda of interested, what do you believe the price difference is between a Rotax 916 and a comparable Lycoming / Continental 160 HP engine?Another way of looking at is mosaic if your a mfg and can make a plane that seats 4 same useful load same speed add on all the extras cirrus sr22 has for cost of $650-700k that’s 1/2 the cost of new cirrus with a more modern reliable motor like new rotax 916s you could steal 1/2 of there market
How many cirrus sr were sold last year?
It needs both. And one might help the other. One down...GA doesn't need MOSAIC or LSA. It needs engine that don't cost $40k to overhaul or $60k+ new. Price out a new IO-520.
Retail, a Factory new Rotax 916 IS is $51,398 and a factory new Continental O-300 (145 HP standard; ~160 HP with STC) is ~$100K and is very hard to get, (You'd most likely need to get a core somewhere and a factory overhaul as a practical matter. Not sure that would be optimum for a new plane.)I am kinda of interested, what do you believe the price difference is between a Rotax 916 and a comparable Lycoming / Continental 160 HP engine?
It’s less than 5% of the cost of a new plane.
Sure it may solve a medical issue or two, but you're not getting the 'take the family to X,Y,Z' bang for the buck.

each new MOSAIC airframe will simply cannibalize the legacy and E-AB portion.
IMO the MOSAIC target market is those of us nursing 60 year old Skyhawks and Cherokees along because a new one is half a million bucks. And also those of us willing to dedicate several years of our life to making our own plane to save $$. And those of us who bought 2 seat sport planes because that's all the law allowed.

Give me a twin 916is bird and I’ll buy it tomorrow, kit or not.
$82,000 when I checked last month, plus a core. Yes, there is a core fee for a new Lycoming., an O-360 is probably $40k,
OK, but will that drop the price from $400k to $100k?
Even a bare bones RV is still a $150k effort (with new engine an low end glass) and that's with NO labor costs.
SP is to limiting. My bad analogy is do you want to ride a motorcycle or drive a car? Sure it may solve a medical issue or two, but you're not getting the 'take the family to X,Y,Z' bang for the buck.
GA doesn't need MOSAIC or LSA. It needs engine that don't cost $40k to overhaul or $60k+ new. Price out a new IO-520.
Looks like an EAB that they plan to convert. The current kit is $160k for the airframe, add $90k for a Garmin G3x setup and a Chinese Rotax knockoff, $30k to upgrade to a 185hp modified 916iS and $70k for build assist. They are advertising 800 hours build time.Well looks like these guys are going to give it try! Like to see if they will ever make it to market

The problem here is volume, or more specifically lack of volume. There were 1,772 new piston airplanes delivered by GAMA members last year. Of those, 180 were twins. Add to that, 1000 or so E/ABs are registered each year. That wouldn't be one day's production at an auto manufacturer's engine plant.

Economies of scale. A Rotax costs $50k because they have to amortize the overhead costs over a far smaller number of units sold.I will admit I do not know much about MOASIC. But, I fail to see how it will result in new airplanes coming to market that are cheaper. It costs what it costs to build and airplane, Rotax 916 is about $50k or more, an O-360 is probably $40k, how does a manufacturer build an airplane around that and keep the cost under $250k?
Just look at the new RV15, projected kit cost I've read is about $170k, plus paint, avionics, and labor.

OK sorry, obligatory PoA-style passive-aggressive insult accomplished. /S

MOSAIC raises the performance limits of LSA. That means more capable aircraft can be produced under a less expensive regulatory framework.
Curious. What percentage of owners do think will want to fully maintain their own aircraft after a 15 day course?MOSAIC also means those 4 seat airplanes can be maintained by their owners after obtaining an LSRM. Huge cost advantage over a 172 or PA28.

hence the 15-day course.Don't they just need to know how to sign off the paperwork?![]()
For one's own aircraft, it's only a two day class. The 15 day class lets you work on other people's aircraft.Curious. What percentage of owners do think will want to fully maintain their own aircraft after a 15 day course?
I think what we're going to see is a high percentage of "hybrid" maintenance being done on 2.0 planes. Many hobby owners, like myself, might take the course in order to legally do a LOT more than one can do today as an owner. But still utilize a 3rd party LSRM or A&P for "heavy maintenance".Curious.

For an S-LSA aircraft... yes, the 2-day class allows you to perform the annual condition on your aircraft and as an owner you can perform the listed prevent mx items in the AMM. However, to perform any other maintenance the owner must have a maintenance rating, ie, the 15 day course. Been that way since day one. Hence the reason a number of S-LSAs were converted to E-LSAs. MOSAIC only expanded the LS repairman privileges to E/AB annual condition inspections with the mx rating allowing one to sign off other E/AB aircraft.For one's own aircraft, it's only a two day class. The 15 day class lets you work on other people's aircraft.
And that will be the interesting part. In some processes, the SLSA paperwork and sign off can be more complex than on a TC'd aircraft. I wonder with the new 2.0 LSA if there will still be a path to E-LSA as with the old versions? I think after a year of LSR-M rules like on a TC'd aircraft some maybe looking to go back to easier times???Don't they just need to know how to sign off the paperwork?
Well, based on my experiences with my owner-assist years, and owners performing prevent mx, I think it will be closer to 30% in the S-LSA category but not linear across all owners.More than zero, but less than 100%.
I think this is closer to the mark but will still be interesting how the "heavy" side will work out after an owner preforms "a lot more" on the aircraft. Another thing interesting is the guidance for the Part 65 previous experience requirement for LSR mechanics is a bit different than for A&P mechanics. What I see in the near future is that in addition the 15 day LSR-M rating there will be factory maintenance courses offered so you can actually perform the mx per Part 65.Many hobby owners, like myself, might take the course in order to legally do a LOT more than one can do today as an owner. But still utilize a 3rd party LSRM or A&P for "heavy maintenance".
Maybe during those 15 days I will learn that I am in over my head.More than zero, but less than 100%.
Kind of like cars, people will probably do what they think they can handle and find a shop for the rest. Billy Bob drops his transmission for the fun of it, while Mary Sue has her wiper blades replaced at the dealer.
I don't expect MOSAIC to put me into a new airplane.
Me neither. But I try to consider "me" generically in this case, not personally. I think/hope the new rules improve things for a lot of me's, especially the younger ones.
