I reached out to Rainbow about the maint topic. They said, ya take the course, fill out the FAA form, take the course approval, and form to the FSDO and add the eab plane. There does seem to be an issue if the plane is in an LLC or not. Anyone have any info on that topic?. E.g. a repairman can't add an LLC airplane because technically the repairman doesn't own it ... I'm curious if anyone has done this with an elsa in an LLC?
