Decision: Route for technical concurrence.
This CCBD requests concurrence on accepting the risk of not performing fitchecks on the following:
- Open on-orbit to on-orbit fitchecks (total of 18). These are fitchecks of tools on this mission that will be staying on-orbit to tools that are already on-orbit.
- Open mission-specific to on-orbit fitchecks (total of 25). These are fitchecks between tools that are on orbit to tools that are going up and coming back down on STS-108/UF1. These fitchecks are all considered low risk.
Decision: Route for technical concurrence.

Decision: Route for technical concurrence.
- H-0924R6 — Update STS-108/UF1 Tools ESEL — XA/Aaron Mears
Revision 6 to the STS-108/UF1 Tools ESEL changes the configuration of EHIP batteries from -302 to -303 and updates serial numbers. It also revises the USA action from R5 to update the current delivery plan of the SAFER onboard trainer.
Decision: Route for technical concurrence.
14. H-1085 — Assess Stowing USA SAFER Hardware in STS-111/UF-2 MPLM — OC/Michael Rodriggs
This CCBD requests an assessment for stowing the USA SAFER hardware in the STS-111/UF-2 MPLM. The hardware will need to be delivered flight ready to KSC by 2/12/02 for Bench Review. The SAFER is scheduled to be launched in resupply stowage rack (RSR) SE157 and return in TBD. The SAFER is subject to the launch/landing load for its specific stowage location. The actual flight loads will be available from the verification loads analysis (VLA) cycle 2 on 3/20/02. An assessment will be made at that time to determine if the loads are acceptable for the SAFER and, if the launch loads are not, the SAFER will be moved to an acceptable RSR locker.
Decision: Route for technical concurrence.
No further items were brought forward, and the EVA Tools and Crew Aids Panel adjourned.
