About 15,000 airports. Or an average of 10-20 airplanes per airport.
About 15,000 airports. Or an average of 10-20 airplanes per airport.
About 25 aircraft on our little grass field. Very little activity compared to 10 years ago. Just 3 or 4 of us are flying, most of the aircraft wasn't be flown for several years, just setting in hangers collecting dust. GA in this state is almost at a standstill. I rarely hear or see a GA airplane except from our field.
I wonder what would happen if Part 103 aircaft were included on that list?
Of the ~200 "homebuilt"* accidents investigated by the NTSB every year, 5-8 are listed as unregistered. Certainly, there are more that are unreported or that the FAA/NTSB ignores because of the Part 103 status. But one still comes out with Part 103 fleet size being significantly smaller than the homebuilt fleet.
* NTSB investigators use the "homebuilt" or "Amateur-Built" flag casually. About 10% of the "homebuilt" accidents each year aren't Experimental Amateur-Built aircraft.
As I analyze each year's registration database, I need to automate the process as much as possible. Hence, I develop standard queries for each type of homebuilt aircraft.
These queries are often more complex than one would think. Let's go through the process of finding the Cassutts.
The registration database has a "Make" and a "Model" field. "Cassutt" is a nice search term, in that it's a unique term. Homebuilts are supposed to be registered with the Make the name of the builder, and the Model, the type of aircraft. So, we plug the term "*cassutt*" into our search term for the model, and get 117 hits.
But...wait a minute, what if someone mis-spells "Cassutt"? Trying the same search term with only one "t" at the end ("*cassut*") we get an additional four hits. Just for the heck of it, try it assuming someone only uses one "s" as well. Nice thought, but there aren't any "Casut"s. Might be next year though...keep it in the query term?
All right, so we use "*Cassut*" as the search term and get 121 hits. Is that all of them?
Hmmm... while the FAA says to use the builder's name as the "Make", some folks don't do that. So let's search for "*cassut*" in the Make, too.
...and get another 26 airplanes.
So, are those all the Cassutts?
When one scrolls down the list of hits, one sees a lot of listings like "CASSUTT III M". Hmmmm....the "III M" seems to be a common model number for Cassutts. Let's add THAT to the search term.
Is the "WELNIAK-BUDDE III M" a Cassutt? Probably. But now there's that little bit of uncertaintly. One starts running the trap line of variations... "IIIM," "111M," "3M", with varying spaces and order, all with wild cards to find them when they're embedded.
And soon have 172 hits. But...a lot of them are obviously NOT Cassutts. A Mig 23M is not a Cassutt, neither is an Antares MA-33M or a Boeing 737-3M8. It's certainly possible to put some additional filters to eliminate the "Mikoyan"s and "Antares"es, but the best approach is to weed out the variations that don't seem to be very productive in resulting in actual Cassutts. So one bags the "3M" searches (while keeping the IIIM variant) and comes up with 148 aircraft.
Then the next guy steps up, and wants to know how many of HIS type of aircraft is out there. :-)
Right now, I've got about 70 different homebuilt aircraft type filters. Some of them overlap...for instance, I've got a search value for "Lancair" in general, as well as for Lancair IVs. With, roughly, 50 of them that DON'T overlap, my database can specifically identify only about 2/3rds of the homebuilt fleet. The rest are a bunch of types that have relatively few examples, or have names that are so far off the "true" that no one could figure out where they came from.
I had just wanted to point out that counting a given type is more than just typing "RV-6" into a search box. It takes effort to achieve some degree of accuracy. That's why I don't have fleet sizes available for more than a few dozen homebuilt types.
OK....here's an attempt to determine the production quantities of the aircraft added to the US registry in 2016.
Pay close attention, class... generating this table was a bit complex.
1. I started with the 3 January 2017 US registration database ("This year")
2. This database was compared to the 4 January 2016 one ("Last year")
3. A "New N-Numbers" file was generated of N-Numbers that were on this year's database, but not the last year's.
4. This "New N-Numbers" file had the aircraft model code and serial number compared to last year's database. This identified the aircraft that, themselves, were not new, but just had their N-numbers changed.
5. Aircraft on the "Changed N-Number List" were removed from the "New N-Number" list to produce a list of what should be only aircraft added to the rolls in 2016.
All the above was performed with my standard "Ignore Drones" filters... aircraft had to have one seat or more, or be lighter-than air.
The resulting list was about 6,000 aircraft long. My net computation of new aircraft (using a simpler process, posted a while back) was about 500 aircraft more. I'm inclined to think the net computation number is more accurate, and that my process may have eliminated some valid aircraft. Also, some companies use temporary US registrations for planes that are to be exported.
No matter, we still have 6,000 airplanes that were definitely new last year. The following table summarizes the number of new aircraft by manufacturer. I have eliminated all manufacturers with a production size of one; the vast majority of these will be homebuilts with the builder's name as the manufacturer. I also eliminated all "obvious" homebuilts...for instance, some builders use "VANS AIRCRAFT" for the manufacturer name, so the "VANS AIRCRAFT" tally was above my 2-plane-minimum threshold.
The list was generated based on the REGISTERED manufacturer name. You will see some companies listed multiple times; this is due to the variation of the manufacturer's names in the various registrations. The variation in "Embraer" is particularly impressive.
You will also see production values for long-dead aircraft companies...Aeronca, Stinson, Ercoupe, etc. This is probably due to previously-deregistered aircraft having their registration re-activated.

GAMA lists actual shipments. The numbers were down for 2015, according to the website. The 2016 numbers will be out in February.
I think Cessna might get a block of N numbers, but not necessarily use them for actual registrations and sales.
Also, the Cessna/Piper etc. numbers will be inflated by previously-deregistered aircraft returned to the rolls, just like the Aero Commanders/Aeroncas, etc.
I do not see one Fisher airplane. I know of three on this forum who own a registered Fisher Airplane. I am sure there are many others who own one of these registered Fisher airplanes.
