In reference to Bill Collum's article in Soaring Magazine (Apr. 2008)
does anyone know what FAA regulations apply to retrofitting a non-
motorized glider with a turbine engine similar to the HPH-304?

Is a special turbine Type certification needed?

If there are two engines, is it then charactorized as a twin engine?

Are there extra certifications nessary for the pilot?

Is insurance readily available for a modified non-motorized glider as
a twin engine turbine?
