Panel Secretary HSMS/ Theresa Elms

Panel Members DX/Kenny Vassigh

EP/ Eric Darcy

ER/ Kevin Lewis

NC/ Ron Cook, Chris Estrada

USA/ Armon Knight

The following items were discussed:

1. Flight Readiness

  • STS—92 (3A) Post-Flight Support

DX requested that ER provide data on post-flight SAFER GN2 levels (post-flight checkout and present level).

  • STS—97 (4A) Manifest Support

ER will replace the blown pyro valve on SAFER unit S/N 1004 with a new pyro valve (and also on 1003 is there is sufficient time to do so).

  • STS—98 (5A) Manifest Support

ER stated that SAFER SED33105900-309, S/N 1004 and either S/N 1003 or 1006 (depending on how the work goes on S/N 1006) will be flying on STS-98:

EP stated that 3 batteries (SED33105907-305) would be picked from among S/Ns 1024, 1025, 1026, 1027, 1028 or 1030 to fly on STS-98.

DX/Kenny Vassigh will verify with DX/Alan Groskreutz if an On-Orbit Stowage Bag is necessary for stowage on 5A.

NC/Ron Cook asked ER to request a memo from LM/James Shu stating that there are no problems with launching the SAFER in the MPLM.

    • CR H-0753 R1 Power Switch Guard Modification

R2 is in work by ER to delay implementation until 6A.

    • CR H-0760 SAFER NBL & 1-G Hi-Fi Mockup Upgrades

Refurbishment and upgrades on Safer Mockup TSED33105900-303 S/N 1001 are in work:

    • Decals are on hand controller are in place

    • Detents to hold hand controller are in place.

    • Hand controller umbilical upgrades are completed.

    • Hand controller tray repairs are completed.

    • Hand controller deployment in work.

    • Delivery date for this mockup will be 11/15/00

Upgrades to SAFER Hi-Fi unit, S/N MU002 is waiting on Dial Latch replacement.

    • CR H-0788, -305 SAFER Battery Design, Fabrication & Implementation

    • CR H-0865, SAFER Thermal Enhancements

The thermal enhancements (-309 configuration) to the SAFER S/N 1003 are scheduled by to be completed by 5A.

Proposed CR’s

    • CR H-0749 R1, SAFER On-Orbit Trainer

Funding has been received for the SAFER on-orbit trainer. ER/Pat McCartney will provide XA will a final cost. DX stated that crew training needs to start 03/01 or 04/01.

    • CR H-0806,-307 Rechargeable Battery CR

Funding will not be provided for the —307 rechargeable battery. There are plans for a "Next Generation SAFER" which will probably not need a dedicated rechargeable battery.

    • CR H-0843, Latch Redesign

On hold until hi-fi mockup latches can be replaced with flight-like latches.

    • Extension of HCM Deployment Actuator and the Manual Isolation Valve Actuator

XA needs redlined comments on the extension CR from ER.

    • IMS Labeling

CR draft in work. SAFER labeling needs to be completed by 7A.

    • On-Orbit Stowage Bag Modifications (Docking Loads)

MV/Dorothy Rasco is working on the problem of locating a subsystem manager. XA stated that if a subsystem manager cannot be found to take over the responsibility, XA will purchase ISS bags that already have their certification.

  1. Issues

The Launch Landing Bag Cushion #528-33548-10 (used on STS-106 and to be used again on STS-97) was reviewed by Gary Morgan and Armon Knight at STS-97 Bench Review. SAFERs 1005 & 1007 were fit checked in the cushion. They observed approximately .5″ clearance around the HCM Slider. No binding was evident.
