  3. H7123 — Removal of Vacuum Water Recharge from EMU Design Specification — HSWL/D. Etter

  4. This CCBD requests revising SVHS7800, EMU Design and Performance Specification, to change the EMU water capacity design requirement of 7 hours EVA duration with 6 hours at maximum average thermal load. The removal of vacuum water recharge from the EVA checklist limits the water quantity to what is presently available in the system.

    At the request of the Chairman, HSWL will consolidate all information on EMU water recharge and release the historical perspective in an EMUM.

    Decision: Hold for release of EMUM. Anticipated date of release is the end of February 2001.

  5. H-0935 — Bearing Module Roll Ring Motor (BMRRM) Vice Clamp Contingency Tool — XA/E. Mohr
  6. During BMRRM removal and replacement, the Acme screw that activates the clamp between the beta gimbal assembly platform and the BMRRM ORU may be forced off center. If this occurs, the locking feature may not engage. This locking feature prevents the Acme screw from backing out.

    This CCBD requests rough concepts, ROM’s and schedules to build a new tool that includes a locking feature for the vice clamp. Results will be presented to ISS Management for a decision on risk vs. cost/schedule.

    Decision: Approve. Redline CCBD to include EC5 hardware inspection trip to Boeing, with concepts, ROM’s and schedules due approximately 2-3 weeks after trip completion.

  7. H-0936 — Additional OIH’s and OIH Bags for SO LTA Cable Task — XA/M. Tullar
  8. This CCBD requests 15 additional OIH’s for the SO LTA cable routing task (twelve 24", three 12"). The OIH’s will be assembled from existing inventory.

    Decision: Approve.

  9. H-0937 — Orlan SAFER Launch Restraint FSE — XA/C. Fulcher

This CCBD requests the design, development, and certification of two Class I Orlan SAFER Launch Restraints and one Class III Launch Restraint Tether.

The following action was assigned:

Action 1/24/01-1: Review Lockheed ROM and generate new cost impact.

Actionee: EC5/R. Schwarz

Due Date: 2/7/01

Decision: Route OSB after new cost impact received.

  1. H-0939 — Cut Handrail to Fit New MBS Requirements — XA/T. Jochim

This CCBD requests modifying the sidemounted handrail as requested by CSA and delivering to KSC for installation on the Mobile Base System (MBS).
