I understand that it is not automatic. that you would have to do the
paperwork, inspections, approvals, etc. But how do people make
alterations to their Standard certification gliders? If I want to add
winglets to my LS-3a, you are saying that it cannot be done (legally, of
course)?



Confused,

If I want to do major modifications to my "Standard" aircraft (ie, wing

"Experimental"?

You can't just make the mods and assume it will be legal and
flyable as an experimental.

There are three common types of Experimental Certifications.

Amateur Built is the best known, and it's not available
unless it's amateur built it and an amateur did 51% of the
building tasks.

Exhibition and Racing is the next most common, and it's the
category in which most factory built gliders without a
standard type certificate are registered (e.g. my Ventus
C). It's my understanding that it's not available if the
aircraft ever had a standard registration.

The last is research. At least in theory, you could modify
an aircraft with a standard registration and get it into
this experimental category, but you wouldn't want to. The
requirements, paperwork and limitations on flight are
extremely onerous.
