The following items were presented:
- PRACA Status — NS43/T. Miller
Fourteen FIAR’s are open for EVA hardware. One FIAR was reported as past due and statused as follows:
JSCEC0796 — Active WIF Assy — Active WIF Control Knob appeared to have increased force to operate.
Hardware passed vibe test. Closure in work; should close by 1/26/01.
One new FIAR was reported and statused as follows:
JSCEC0848F — Equipment Hook SEG33108365-302. At the end of EVA1 (STS-97), EV2 experienced an inadvertent equipment hook release from the ISS Torque Wrench. There were two equipment hooks with slide locks at the time of the release.
Functional tests will be run on all hooks that flew and rationale obtained for closure. Interim’s for STS-98 and STS-102 should be complete by 1/24/01.
STS-102 FIAR’s were statused as follows:
BFCE029F105 — Pistol Grip Tool (PGT). PGT chatter.
EC5/G. Nickel has E-mailed the EVA community with recommendation to close out FIAR as
"Explained". If all concur, the FIAR can close.
The following USA SAFER FIAR’s were statused:
JSCER0033 — USA SAFER. NSI trace on oscilloscope appeared abnormal.
Undergoing internal review.
JSCER0034 — USA SAFER. SAFER battery thermistor bad solder joints.
Drawing change in work.
JSCER0035 — USA SAFER. SAFER battery erratic current readings.
Battery is on-orbit. Will troubleshoot upon return.
The EVA hardware oldest FIAR, opened against the Adaptive Payload Carrier, is 505 days old.
FIAR’s open by flight are:
STS-98 1
STS-102 7
STS-100 7
STS-104 10
- Cert Status — NC52/G. Wright
There are two open certification items for STS-98. Certification paperwork for the Hydrazine Detection Pad is expected today. According to OSS, certification for the Trace Gas Analyzer may take all week. There are two open certification items for STS-102. The QD Cap Removal Tool was shipped from GSFC Friday (1/19/01) and needs to be shipped to USA for Bench Review. Certification for the EVA Ohmmeter is pending receipt of the Materials Memo. A CR to change the CARD has been written and will be processed OSB. There are four open certification items for STS-100.
- Mission Hardware Status — LOC/K. Thomas
- Actions Review — XA/D. Roberts
The following mission hardware status was presented:
STS-102: The majority of hardware has been sent to USA for Bench Review and flight. One item waiting to be shipped is the EVA Ohmmeter. 1027’s are needed for the crew hook lock assemblies. PIA’s are in work for the Bulb Assembly, complete for the EHIP/PGT Cable and EHIP Battery Pack and in work for the EHIP Lights.
STS-100: Al hardware shipments are on schedule.
STS-104: All hardware has been shipped except the Large Cutter Panel Assembly and General Purpose Cutter, Flood Bulb Assembly, Spot Beam Reflector Assembly, OIH Carrier Assembly, EVA OIH Assembly, and the Safety Tether.
This item was deferred.
- Pending CR Review — XA/D. Roberts
- HITS Status Review — XA/J. Manning
This item was deferred.
This item was deferred.
- H-0935 — Bearing Module Roll Ring Motor (BMRRM) Vice Clamp Contingency Tool — XA/E. Mohr
Background: During a BMRRM removal and replacement on P6, the vice clamp EVA bolt may not engage its locking feature due to vice clamp rotation.
This CCBD requests rough concepts, ROM’s and schedules to correct this failure mode.
Decision: Present to 1/24/01 EHB.
- H-0934 — P6 4-Bar Mechanism Fix — XA/E. Mohr
- H-0936 — Additional OIH’s and OIH Bags for SO LTA Cable Task — XA/M. Tullar
Background: One of four latches on each of the P6 4-bar mechanisms failed to lock. Preliminary meetings were held with EC and Boeing to discuss this issue. Concepts discussed were a socket to rotate the pivot pins on the 4 bars, or an alternate clamping device that would replace the latching feature on the mechanism.
This CCBD requests rough concepts, ROM’s and schedules for each of these concepts.
Decision: Route for technical concurrence.
This CCBD requests 15 additional OIH’s for the SO LTA cable routing task (twelve 24", three 12").
Decision: Present to 1/24/01 EHB.
- H-0937 — Orlan SAFER Launch Restraint FSE — XA/C. Fulcher
- Provide Alodine Strips on Square Grids Located on EVA Tools — BOE/S. Burks
- STS-102 Tool-to-Tool Fitcheck Status for CoFR2 — HSMS/J. Case
This CCBD requests the design, development, and certification of two Class I Orlan SAFER Launch Restraints and one Class III Launch Restraint Tether.
Decision: Present to 1/24/01 EHB.
The Flight Releasable Attachment Mechanism (FRAM) Project is requesting Alodine strips be provided on the square grids located on the EVA tools. Currently, there is no ability to allow hardware that is temporarily stowed on EVA tools to be grounded and no prepositioning capability.
The following action was assigned:
Action 1/22/01-1: Provide ROM for assessment of CETA cart, OTD and TERA grounding path and any necessary modifications to hardware and present to 2/12/01 Tools Panel.
Actionee: EC5/L. Bailey
Due Date: 2/12/01
This presentation will be reviewed by the Tools Panel Chairman and forwarded to XA I&O.
- Walk-on: CETA Robotic Compatibility — EC5/L. Bailey
The CETA is manifested on ISS 9A and 11A. No requirements currently exist for CETA robotic compatibility. This proposal requests the ISS Program provide detailed robotic compatibility requirements in order for EC to make appropriate CETA modifications. The Chairman will discuss this issue with XA Management.
- Walk-on: CETA-MT Physical Verification — EC5/L. Bailey
- Walk-on: APFR Usage on ISS 6A for SSRMS Deployment — EC5/L. Bailey
No requirements exist for physically verifying Crew and Equipment Translation Aid (CETA) translation with the Mobile Transporter (MT) on segments or CETA-to-MT interfacing in a parked condition. This proposal requests the ISS Program provide physical verification requirements for CETA and MT. This was presented as information only. Any requests for ROM’s or implementation will be discussed beforehand with ISS.
APFR use in SSRMS deployment task on 6A may trip load limiter due to loading conditions of task. This proposal is to inform the EVA community of the risk associated with performing this task and reiterate APFR operational restrictions/constraints for crew training.
- Walk-on CCBD: Cut Handrail to Fit New MBS Requirements — XA/T. Jochim
This proposed CCBD requests modifying the sidemounted handrail as requested by CSA and delivering to KSC for installation on the Mobile Base System (MBS).
Decision: Present to 1/24/01 EHB.
No further items were submitted and the Tools Panel adjourned.
