DECATUR, TX, JUNE 17, 2008: United Rotorcraft Solutions (URS), and partner Ahlers Aerospace, were recently awarded FAA Supplemental Type Certificates for their Night Vision Lighting modifications for the Bell 206 Series and the Eurocopter AS350B2/B3.
Using new filter material that greatly improves day light readability, United Rotorcraft Solutions and Ahlers Aerospace have designed a modification utilizing external NVIS White filters of glass or poly carbon applied to both instruments and displays. Filter selection is predicated on the light source, whether incandescent, florescent, LCD or LED.
The filters are generally mounted in an aluminum frame and affixed over the instrument’s bezel utilizing the existing instrument mounting screws. Mechanical and/or electrical modification to the cockpit or airframe is minimized reducing installation charges. The external filters allow the modified component to remain generic thus retaining the advantages of local repair and/or overhaul.
STCs are pending for the Bell 412 and the Eurocopter EC120, EC130, EC135, EC145 and BK117 series model helicopters with award expected in the near future.
United Rotorcraft Solutions, FAA Repair Station UX9R241Y, provides aircraft completions and refurbishment services, systems integration, maintenance, component overhaul, customized interior installations and unsurpassed exterior finishing on most model helicopters and some fixed wing aircraft. They also offer FAA approved NVG compatible lighting systems for many models.
