Installation of NVIS/NVG Compatible Lighting does not include or imply approval of flight operations with NVGs. The operator must receive a determination from their civil aviation authority if an approval to operate with NVGs is required.

Any subsequent deviation to the cockpit/cabin configuration specific in the type design of this STC may affect compatibility of the NVIS and will require a re-evaluation for NVIS cockpit and NVG compatibility. The aircraft is not certificated for NVG operations until the evaluation is completed. Once the aircraft is modified with this STC, any future modification to the aircraft may also affect compatibility with NVG and may require a re-evaluation by the FAA Flight Test Branch.
