The first AD's mandated that information be sent to the Mfg.

I have not heard of any response from the Mfg.

I think they can figure out from their various dealers, plus the on-
line registries of the FAA and other countries related government
agencies, how many are in service (A LOT, IMO) and they know how many
they built!

For now, let's put some more comments on the FAA website! Of the
thousands that have flown Blaniks in the USA, I can't believe only
less than 20 have done so!
