STS-100: As reported last week, hardware needed for the STS-98 MPLM Bench Review on 11/15/00 is at USA. This hardware will be brought back after Bench Review so a 1027 can be written to properly ship for flight.
The early de-stow issue was discussed and the Panel agreed that a process needs to be put in place as this is becoming a recurring problem with the current tight flight schedule. Per USA, there is no space for the early de-stow items. The Chairman assigned the following action:
The following actions were statused:
Action 9/25/00-5 – EC5/C. Chang: Hold splinter meeting to discuss ISS slidewire integration to slidewire carrier and review 5A MOD installation procedures.
CLOSED.

Action 9/25/00-6 – XA/J. Dutton: Conduct splinter meeting to investigate reported STS-99 anomaly on slidewire installation. Report findings to Tool Panel.
CLOSED. Findings indicate _" slack available. Installation harder on-orbit than doing fitcheck. Will give "no problem to proceed" to FRR.
Action 9/25/00-3 – DX3/R. Gauvreau: Based on data at hand, confirm flight, training quantities and come up with length of tool (Ref: H-0711 – 3/6" Allen Drive with Drop Proof Tether Adapter).

- FCE/EVA – Hardware Return Recommendations – USA/V. Lilly-Tallman
Background: Action 11/6/00-1: Present recommendations to accommodate early de-stow items.
This presentation outlined mission-related shipping/receiving activity. As outgoing shipments get priority, the following was suggested:
- Don’t return/re-process hardware if unnecessary. Example: TSA tools may be kept in place if 1) hardware not used, 2) stowed limited life not exceeded where applicable .
- For critical turnaround hardware – Add to Landing Site Disposition Report. This hardware is given top priority upon receipt into FCE/EVA Shipping/Receiving.
If a whole locker is early de-stowed, a process of prioritizing needs to be put in place. An itemized listing of contents is also required.
The following action was assigned:
Action 11/13/00-5: Look at early destow lockers.

Due Date: 11/20/00.
