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.
