The 2007 Nall Report is out:

But I'm having a hard time believing the numbers presented in Figure 35 on
page 24 (which is explained in the first paragraph on page 25). I'm pretty
confident that there are more than 2,972 registered experimental aircraft
in 2005. (Unless they mean the total registered in just that year and not
the total of all active registrations. But I'm not sure the former number
is meaningful or useful in the context of their statistics.)


I download the FAA Registration database every January. Here's the summary of
Experimental/Amateur-Built aircraft by date of download:

1/9/2004 26593
1/9/2005 27614
1/7/2006 28539
1/8/2007 29427

I suspect a digit got dropped on the Nall Report. The net increase in
homebuilts is about 1,000 per year, but the actual increase is closer to 1,300.
