Actionee to coordinate with XA/G. Lutz.
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.
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, ROMs 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, ROMs and schedules due approximately 2-3 weeks after trip completion.
This CCBD requests 15 additional OIHs for the SO LTA cable routing task (twelve 24", three 12"). The OIHs will be assembled from existing inventory.
Decision: Approve.
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.
- 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).
Decision: Approve.
No further items were brought forward, and the EHB meeting adjourned.
