About this file
This document is a detailed engineering drawing for a NASA Armstrong Flight Research Center component called a "Strongback Cap Channel". The part is manufactured from Aluminum 6061-T6 C-Channel, measuring 15.00 x 3.40 inches, and is designed with specific manufacturing and finishing requirements. Key specifications include chemical conversion (Alodine) finish, two coats of polyurethane paint in OSHA Safety Blue, and human-readable identification marking per MIL-STD-130. The drawing includes precise dimensional tolerances, surface roughness requirements (0.125 microinches max), and is marked as CUI//SP-EXPT (Controlled Unclassified Information/Special Export) with an EAR99/NLR (No License Required) export classification. The drawing was created and reviewed by NASA personnel on September 2nd and 17th, 2025, with the part number 1JYR2-FLL-HPROJ-0005-101.

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.
