4632 W. Aeronca Street Boise ID 83705 23 14 CFR.

A19SW Air Tractor 802A, 602, 802 Installation of a Supplemental Lighting System manufactured and installed in accordance with Aviation Specialties Unlimited (ASU) Master Drawing List (MDL) MDL-802004-3, Revision D, dated June 7, 2019, or later Federal Aviation Administration (FAA) approved revision. Maintained in accordance with Instructions for Continued Airworthiness (ICA) ICA-AT802004-4, Revision IR, dated March 24, 2018, or later FAA-accepted revision. Operated in accordance with Flight Manual Supplement (FMS) FMS-AT802004-6, Revision B, FAA-approved June 10, 2019, or later FAA-approved revision.

This supplemental type certificate applies to the models listed above and only to the specific serial numbers as listed on the ASU MDL.

These aircraft employ 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 modification 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 modification 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.
