I rather think that under EASA at least it's the NAA that issues the Type Rating, not a manufacturer, but I could be wrong.
So far as experience requiorements go...with due credit to ELGD..........................
Part-66 requires that a satisfactory amount of
experience is required for an aircraft rating, in addition
to the training. As a guide, 4 months is considered to be
acceptable although the experience required will
largely depend on the licence(s) and rating(s) already
held. Where a similar aircraft type is held to that which
is being applied for, experience can be reduced
however, the experience should not be less than two
weeks.
For each application, the CAA will need to satisfy itself
that the practical training is of sufficient duration before
adding a type rating.
There are also the tasks that must be signed off before a rating can be applied for. Fewer for those with proven relevant experience.
So it's not quite as bad as it might seem. And you can get dreadfully seasick on a ferry.
None of the above applies to the B3 AMEL, as far as I know, if such a thing actually exists yet.
