Page __ _ of SA02700SE Limitations and Conditions: (cont’d)

This aircraft 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 may require a re-evaluation by an FAA aircraft certification office.

Installation of this NVIS system does not authorize the operator to use NVGs. If the type of operation requires an operational authorization, the operator must coordinate with the FAA or with the responsible aviation authority to obtain this authorization. A copy of this certificate, the MDL, the ICA, and the AFMS, must be maintained as part of the permanent records for the modified aircraft.

If the holder agrees to permit another person to use this certificate to alter the product, the holder shall give the other person written evidence of that permission.

Certification Basis:

Model 500S: The certification basis for this modification is based upon 14 CFR, Part 23, Amendment Level 23-0, except for §23.1309 which was demonstrated at Amendment Level 23-14, and §23.1529 which was demonstrated at Amendment Level

23-8.
