Limitations and Conditions: This rotorcraft employs Night Vision Imaging System lighting, commonly named NVIS, that has been certified to ensure the aircraft is compatible with Night Vision Goggles (NVG). For this reason, interior and exterior modifications that add or change systems that emit or reflect light have the potential to alter or change the NVIS lighting vs. NVG compatibility. Compatibility of this design with subsequent modifications must be determined by the installer. The determination of compatibility with modifications that emit or reflect light must include an engineering compatibility evaluation approved by an aircraft certification authority. A copy of this certificate and the FAA-approved Rotorcraft Flight Manual Supplement (RFMS), FMS-A1097273-6, approved August 18, 2008, must be maintained as part of the permanent records for the modified aircraft. Note: The holder cannot use the descriptive data about this design to duplicate other products. This approval is limited to only the installation made in an Agusta, Model A109AII, serial number 7273. This STC does not permit manufacturing of parts for multiple installations.
