    2021 EAB Aircraft Registration Summary

    As usual, I've downloaded the end-of-year FAA registration database and run my various processes to examine the trends for a number of homebuilt aircraft types. Note that these count only aircraft registered as Experimental Amateur-Built. It does not count aircraft that do not list a certification type (about 5,000 aircraft with homebuilt-like names) nor aircraft registered as Special Light Sport or Experimental Light Sport (e.g., SLSA or ELSA RV-12s).

    Thank you!

    I really like the service you provide with the community, as it gives a window into where the E-AB community's head is. Some planes have gone down in popularity (as some fall off, there's not much to replace them), some have risen.

    And a few remain steady over the time. The Pietenpol is the antithesis of C&C cut aluminum sheets with pre-drilled holes, yet it's numbers remain relatively unchanged since 2013.
    The opinions and statements of this poster are largely based on facts and portray a possible version of the actual events.

    It's even more interesting in that the figures I post are the *net* aircraft. In the nine-year period covered here, about 250 Pietenpols were removed from the FAA registry. The net has only dropped by 25 aircraft or so...that means that about 225 airplanes were added! Some of them are probably previously-deregistered aircraft, but that's still pretty good.

    That's nothing, I'm waiting for an RVer to complain "Why do you show only 6940 EAB RVs on the FAA registry, and Van's says 11,000 have been completed!"

    The one that comes as a surprise is Velocity. The baseline number of airplanes is relatively small, the factory is still in operation, yet the number of registered aircraft ain't moving.

    Well, you are looking at the net change. During 2021, four EAB Velocities were removed from the registry. So four new ones were added to keep the net at 228. Still, that's not a lot....

    While I appreciate the work done in reporting this, and I understand the issues with searching the FAA's database when anyone can call their aircraft anything they want and the plethora of typo's, I also have to protest the glaring absence of the Breezys, Woody's Pushers, and certainly all the Wittman aircraft, Tailwinds in particular.

    And every year, people complain of the lack of Dyke Deltas, Polywagons, VariViggens, Stits Playmates, Windwagons, etc. Inclusion on the list above is not a reflection of how important I feel the designs are, though I make an effort to include the most-numerous examples. The less-numerous designs are often included due to curiosity or the fact that I *know* someone who owns a particular design (this started as an EAA Chapter presentation). The Benson Gyrocopter had the *highest number of registrations*, back when I first started running these analyses back in 1998. That's why it's still included. In any case, it really highlights how the FAA's re-registration process has hammered homebuilt totals.

    If you add up the totals for the aircraft types for 2021 in the above table, you get 18,318 aircraft. Yet the total fleet size, as shown on the last line, is 27,117. So yes, there are about 9,000 homebuilts of other types that are not individually split out.

    As you mention, the homebuilt's make/model are up to the builder's whim, as are the actual spelling of the names. That's what gets fun when trying to identify aircraft. I mean that literally; it's kind of a detective story.

    Take Breezies, for instance. I first ran a Model name search for "*Breezy*". Then I noticed that a lot of the Breezies have a "RLU-1" designation. So then I add "*RLU*" to the filter, and get eight additional registrations that *don't* have "Breezy" in the name. It doesn't catch the one called "R.L.U.-1" (the periods throw it off), but that one also already had "Breezy" in the name anyway.

    But there's still a lot of uncertainty. Is a "GE-1 Breezy" the same aircraft? What about a "Naked Angel Breezy" (N11DD)? I'm guessing they are...but with the total "hits" on the filter only coming to 80 or so, the accuracy of the tally comes into question. And, of course, the same filters have to be applied to the "Make" entry, too, because some people put "Breezy" into the "Make," not the "Model".

    There's LESS worry about more-numerous types such as the RV-6. I still have to search for "RV-6", "RV6", "RV 6" and even "VANS SIX" (with wildcards of course), but almost all builders put a variation of "RV" and "6" in the model name. Still some misses, still some OTHER types of aircraft, but when you've got nearly 2,000 airplanes, the false hits and the misses have less impact.

    The table above is the result of building about sixty such filter sets, and running them against a each year's FAA registry. Once the filters have been developed, they're added to a macro I've generated. With the macros, generating the above table takes only a few minutes.

    I have added types to the automated processors. A year or two back I realized that the Carbon Cub was giving some of the RV models a run for their money, and added the type. Where the effort comes in is the need to run the same effort against the individual databases running back to 2008 (I post only back to 2013 because of the forum's posting-size limit). THAT is time-consuming, as the appropriate filters have to be copied to each individual registration year and, sometimes, updated to reflect the older versions of the registry.

    Anyway, now you know.

    Speaking of the FAA's Re-Registration process (started in 2010), this table shows the homebuilt types that lost 50% or more of their registrations since 2008.
