I would like to get a new bubble windshield and all the other glass in a dark grey tint. Does anyone know where I can find them?
Hi Guys,
I'm admittedly ignorant of such authority as one might incorporate by reference on a 337 (or other means) to substitute Lexan for Plexiglas, etc. materials as originally proposed, presumably CAA/FAA approved, specified and installed in production aircraft of specific certificated design? (i.e., what makes such substitution "legal" so as not to invalidate the bird's airworthiness certificate and, thereby, insurance?)
The optical characteristics of these materials do differ, although such would be of much more significance in thicker material used for a bubble windshield than that normally used for rear windows and sidescreens. Lexan IS much more forgiving to work with, no argument.
If the "owner-fabricated" parts permission relates, is there not still a requirement that materials and methods used on certificated aircraft conform to those "approved by the administrator"? Is Lexan such a material, and installation of same on a certificated aircraft such a method?
Does anyone know of any "legal" home-brew bubble windshields (flat would be much easier) of Lexan actually installed out there?
Has anyone had clear panels tinted by automotive professionals and subsequently been successful in getting the installation signed off by appropriate authority? There does seem to be some precedent to using removable tint films, although a professional-appearing application to the inside contour of a bubble windshield would seem unattainable given the fact that butted seams will separate 1/16"+ over time.
Merry New Year to One and All!
