  1. H7109 — Phase VI Glove TMG RTV Vacuum Thermal Bake-out for STS-109 (HST-03B) — HSWL/Tom Chase
  2. This CCBD requests implementation of GSFC HST requirements for thermal vacuum bake-out for eight pairs of EMU Phase VI glove TMG’s for use on HST-03B. These eight pairs of TMG’s will be removed from production at the point just before installation of the 12-volt electrical heater harness, shipped to JSC to perform the bake-out, then returned to ILC-Dover for completion of the manufacturing process. The eight pairs of Phase VI glove TMG’s will be delivered to USA consisting of four flight TMG’s and four backup TMG’s. Each TMG will be identified as having been baked-out so that no RTV is added during processing or fabrication subsequent to the bake-out.

    Decision: Approve.

  3. H-0967 — STS-100 (6A) Open Tool-to-Tool Fitchecks — HSMS/A. Hall

This CCBD requests EHB concurrence on accepting the risk of not performing all tool-to-tool fitchecks for STS-100. Open payload bay fitchecks and TSA fitchecks remain on the MMWS RH Swingarm S/N 1004 and 1005. A total of 34 fitchecks will remain open for STS-100.
