STC Retrofit Kit Installation
The installation of the Citation X winglet STC Retrofit Kits are currently being performed at Textron Aiviation owned Service Centers. The owner / operator contracts directly with the Textron Aviation Service Center for installation of the winglet STC Retrofit Kit. Textron Aviation Service Center provides a five year limited materials and workmanship warranty for the installation of the winglet STC Retrofit Kit. The existing Textron Aviation limited airframe warranty is unaffected by the installation of the winglet STC, subject to the terms and conditions of that warranty.
