The answer you seek is found in part 23, which has to do with
certification of aircraft. Most, but not all, aircraft flying today

Most light aircraft are certified under Part 23. Most serious aircraft
are
certified under Part 25.

There are many more Part 23 airplanes than Part 25 airplanes, in the US.


There are more Fords than BMWs, too. So what?
