STS-100 RDRs: The Phase VI Glove Heater element, Phase VI Glove Restraint abrasion, low circuit voltage on the Advanced Battery, relief valve lock nut adhesive loose on the IC Battery, and the Advanced Battery Relief Valve reseat RDRs are planned to close by 3/29/01. A new NFC is in the signature process for the RDR on loss of power indication on the Middeck Battery Charger.
STS-104 RDRs: The METOX RDR (regenerator oven solenoid did not actuate canister state indicator) will be statused at the next EMU Panel and EHB.
There are no open certification items to report for STS-100.
The are 27 open certification items for STS-104 (7A). Most will come off with ESEL revisions. The SSER cert is in work. Joint A/L stowage items cert package is in the review cycle.

Several FEMU-R-001 changes are in work. Fixes to be brought to EMU Panel.
- H7109 Phase VI Glove TMG RTV Vacuum Thermal Bake-out for STS-109 (HST-03B) HSWL/Tom Chase
- H-0967 STS-100 (6A) Open Tool-to-Tool Fitchecks HSMS/A. Hall
This CCBD requests implementation of GSFC HST requirements for thermal vacuum bake-out for eight pairs of EMU Phase VI glove TMGs for use on HST-03B. These eight pairs of TMGs 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 TMGs will be delivered to USA consisting of four flight TMGs and four backup TMGs. 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.
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.
Decision: Approve.
No further items were brought forward, and the EHB meeting adjourned.
