Online Community of Zenith Builders and Flyers
The plans have no information to guide the installation of the optional fiberglass doors.
The builder resources on Zenith's website have an aged photo assembly guide that leaves out a key piece of info...The upper door sills must be trimmed 20 mm ( from 80 to 60mm in height). Otherwise the door hinges will not align with the door's upper flange, instead they will want to align on the plexiglass.
I confirmed my findings with another builder's experience here:
The photo assembly guide gives one the impression that the fiberglass doors are retrofittable to aircraft with original doors as was done on the factory 701. The new doors must be taller than those shown.
