    The Annual Registration Summaries

    It's the first of the year, time for me to download the FAA aircraft registration database and provide some insights.

    "All" is the total number of registrations
    "Net" is the change in the number of registrations vs. the previous year
    "New" is the total number of new aircraft registrations. This is based on the "Net" value, corrected by the number of aircraft that had been de-registered that year.

    Obviously, there was a big jump in the number of aircraft de-registered last year. Where this usually causes problems is when some bright spark tries to join two unrelated statistics...namely, the FAA registration database, the FAA estimate of annual flight hours, and the NTSB accident statistics.

    Despite a nearly 2,000-aircraft reduction in the number of registered homebuilt aircraft, the number of ACTIVE homebuilts didn't decrease by that much. But since the "official" number of homebuilts dropped by almost 7%, someone will claim that the total flight hours flown by homebuilts last year ALSO dropped by 7%. This is probably not the case.

    Plus, if someone then tries to compute fatality/100,000 flight hours, the supposed reduction in flight hours will make it APPEAR that the accident rate increased.

    Now, word is that the number of EAB accidents was at a low last year. That should help, but one should, again, keep in mind that there are some loosey-goosey (pardon my French) games being played with these numbers.

    Next step will be to extract the numbers of specific homebuilt types from the registry, and post the fleet sizes.

    OK, here's the number of registered EAB examples of a wide number of types. Note that the overall homebuilt fleet decreased by almost 2,000 airplanes last year, so most of these types took their share of the hit.

    This data includes only aircraft listed in the FAA registry as Experimental Amateur-Built. It includes (of course) only US-registered aircraft, and does not include:
    - Aircraft with homebuilt-like names that are registered in some other category or do not list a certification category in their listing
    - Aircraft that have been removed from the FAA registry, either by not renewing their registration at the scheduled time or having been manually removed by the owner or insurance company.
    - Kits that have been built and registered in other countries, or completed aircraft that have been exported to other countries.

    Ron, The Volksplane number of 48 agrees with my count. I did it the hard way, pulling up all the Volksplane possibilities, and confirming the currently registered N numbers. I have the single seat SA100 Starduster total at 22, but no number for the Starduster Too. I have 138 registered KR-2 aircraft, but this number does not include the KR2S. These were confirmed in the same fashion as the Volksplane.

    One more aircraft, this one not in your list: 36 registered Stits SA-3A Playboys.

    Thanks for this information...us number types love it!
