1.0 Scope

The National Aeronautics and Space Administration (NASA) completed structural modifications on a Gulfstream V (GV) aircraft (S/N 672) in 2018 – 2019 in which two nadir (down) looking optical viewports were installed, including necessary aircraft system relocations, to support the Airborne Science Program (ASP).

ASP recently purchased, in conjunction with NASA Armstrong Flight Research Center (AFRC), a GV (S/N 570) that requires the identical viewport modification. See Figure 1-1. The intent of this Statement of Work (SOW) is to use the existing GV S/N 672 modification technical data as the baseline for a nadir viewport modification with minimal design deviations to account for GV S/N 570 differences. Repairs (Minor/Major) and Alterations (modifications) shall meet Federal Aviation Administration (FAA) Code of Federal Regulation (CFR) 14 certification.
