About this file
This document is a detailed engineering drawing for NASA's Armstrong Flight Research Center, specifically for Strongback Floor Beams (drawing number 1JYR2-FLL-HPROJ-0004). The drawing depicts two floor beam components (-101 and -103) made from steel ASTM A992/A572-50 C-Channel C15X33.9, with precise dimensional specifications and tolerances. Key technical requirements include surface finish, primer/topcoat specifications (MIL-DTL-18264), epoxy primer, polyurethane coating in OSHA Safety Blue, and human-readable identification marking per MIL-STD-130. The document is marked CUI//SP-EXPT (Controlled Unclassified Information/Special Export) and contains detailed manufacturing notes regarding machining, tolerancing, and surface roughness requirements, with the drawing controlled by A.C. Holguin from NASA's Armstrong Flight Research Center.

I believe note 1 is another way of communicating a UOS profile note.
I think I can use the example of a cast part to GD&T the channel.
