About Our Windows
API’s FAA-PMA King Air polarized aircraft window elements operate by simply rotating one of the polarizing elements (inner rotator) against the other (outer fixed). The window will then become progressively darker and darker until it is virtually black.
In addition, not only do our windows reduce the amount of glare, but they block harmful UV radiation exposure and help the interior remain cooler longer.
At API we take pride in providing the highest level of customer service, leading edge technical knowledge, and stringent quality control. Eclipse® polarized aircraft cabin window elements meet or exceed all original equipment specifications and performance criteria.
King Air FAA-PMA Applicability
Our King Air Windows are made under FAA-PMA for the following aircraft:
300 Series (Including Super King Air 350)
Non-King Air Windows
With guidance from the FAA, API can produce windows for aircraft other than Kings Airs. Non-King Air polarized aircraft cabin windows are
manufactured under FAR 21.9(a)(5) (Owner Produced Parts).
API requires an authorization letter from the owner/operator and a nonreturnable sample of the window being replaced. We then manufacture the window to the dimensional specifications of the customer provided window.
The sample window must come from the plane being serviced and the windows we make must only be installed in that plane.
As with our King Air windows, our window materials are burn tested annually to insure conformance with FAA/FAR 25.853(a) and Appendix F, Part I, paragraph (a)(1)(v), Horizontal Burn Test, as published in the Federal Register and Amendment 25-83 (effective March 6, 1995).
