The following items were presented:

Hardware Integration Schedule — XA/B. Counts

Changes to the schedule include the STS-98 launch slip to NET 2/6/01, STS-102 flight ship on 2/12/01, and late ship on 2/14/01, STS-100 CEIT ship on 2/16/01, and STS-104 ISS A/L CEIT on 3/5/01. Based on when STS-98 launches, dates should not slip much further out.

PRACA Status — NS43/T. Miller

A total of 16 FIAR’s are open for EVA hardware and are shown by flight as follows:

STS-98 1

STS-102 10

STS-100 9

STS-104 13

Two FIAR’s were reported past due and statused as follows:

JSCEC0796 — Active WIF Assy. Active WIF control knob appeared to have increased force to operate.

Vibe test complete. Can close.

JSCEC0837F — MMWS. Sticking/binding of gimbal.

Being routed for signature.

One new FIAR was reported:

BFCE026F005 — Disk/Loop Pin Puller Tool Caddy. Upon return from STS-97, tether cord broken on loop pin puller.

Per EC5/R. Schwarz, the cord is worn on the entire Shuttle fleet and has never been updated due to cost. The cords are visually inspected every 3 years or every time it’s used on EVA. An interim has been written for STS-98; however, it is on hold pending input from CB/C. Noriega on whether the cut could have been due to sharp edges.

The following action was assigned:

Action 1/17/01-1: Develop ROM on retrofitting cords.

Actionee: EC5/R. Schwarz

Due Date: 1/24/01

The following STS-102 FIAR’s were statused:

JSCEC0838F — Modular Mini-Workstation Gimbal. Sticking/binding of gimbal.

In signature loop.

BFCE029F105 — Pistol Grip Tool (PGT). PGT Chatter.

Need EC5/G. Nickel reading as to whether or not to close out the IFA. No good explanation; unable to duplicate failure. Will work up closure rationale by end of week.

JSCEC0839 — REBA Charger. REBA failed to show green LED during acceptance testing.

Need better root cause from vendor.

JSCEC0841 — PFR Gimbal Assembly. Roll joint buttons binding.

EC5/R. Schwarz to coordinate with EC5/D. Glebe for latest update.

The following SAFER FIAR’s were statused:

JSCER0033 — USA SAFER. NSI trace on oscilloscope appeared abnormal.

ER/W. Guy reviewing closure. Should have closed next week.

JSCER0034 — USA SAFER. SAFER battery thermistor bad solder joints.

Waiting on updated drawings. Should be able to close next week.

JSCER0035 — USA SAFER. SAFER battery erratic current readings.

Currently on-orbit. Can’t work until back on ground.

The oldest FIAR, against the Adaptive Payload Carrier, is 498 days old.

Certification Status — NS22/G. Wright

There are two open hardware certifications for STS-98 — the Hydrazine Detection Pad (Gold Salt), and Trace Gas Analyzer. The Hydrazine Detection Pad needs thermal and vacuum tests. The cert package on the TGA is being reviewed today. There are two open hardware certifications for STS-102 — QD Cap Removal Tool and EVA Ohmmeter. Certification paperwork on the QD Cap Removal Tool was shipped yesterday. The Materials Memo on the Ohmmeter should be signed off by next Friday. There are seven open hardware certifications for STS-100.

EMU RDR and Certification Status — NC512/C. Sager

The total open EMU RDR’s by flight are as follows:

STS-98 0 -

STS-102 5 - Interim closures on 3; 1 requires CCBD

STS-100 2 - 1 in final closure; 1 with interim

All certification is closed for STS-98. There is one open certification item for STS-102; the EMU Advanced Battery. There are seven items requiring certification for STS-100; most are ESEL revision/serial number updates. There are 13 items requiring certification for STS-104; most require Station cert or changes of part numbers or serial numbers.

Funds Transfer Status — XA/J. Hall

The following funds were transferred this reporting period:

Trace Gas Analyzer Support – $193K

EMU Logistics Status — XA/B. Johnson

This item was not presented. Beginning in February, the EMU Rotation Plan will be presented on a monthly basis on the last Wednesday of the month.

EHB Action Status — XA/G. LeStourgeon

The following EHB action items were statused:

H-0931 — OTD Tether Reconfiguration — XA/K. O’Brien

This CCBD requests reconfiguring the OTD, P/N SEG33106254-303, S/N 1003, with two ORU Tether Assemblies rather than the current configuration of one ORU Tether and one Retractable Tether. The Retractable Tether from OTD S/N 1003 will be used as a spare/replacement unit for the on-orbit OTD S/N 1004. OTD S/N 1003 will be reconfigured with two ORU Tethers. Per EC5, cost to build two ORU Tethers is $12-15K.

Decision: Approve.

The following action was assigned:

Action 1/17/01-2: Hold discussions on funding for additional OTD tethers and spares.

Actionee: XA/J. Dutton

Due Date: 1/31/01

On-Orbit FIAR’s Status — XA/K. O’Brien

There are currently six tools on-orbit with unaddressed FIAR’s that were opened against these tools when they were already on-orbit. The tools were placed in three categories, as follows:

Leave On-Orbit and Use As-Is

ORU Transfer Device

Adjustable Fuse Tether

Bring Home for Rework

High Strength Bridge clamp

Push Button Articulating socket

On-orbit Replacement

ORU Tether

Tether Reel on OTD

The FIAR on the ORU Transfer Device still needs to be resolved. After a meeting on the Adjustable Fuse Tether FIAR’s it was determined that the tool stay on-orbit. The FIAR’s have been closed on the High Strength Bridge Clamp and the Push Button Articulating Socket and the tools will be returned for rework. The Tether Reel and ORU Tether FIAR’s will be resolved with approval of H-0931.

Decision: Approve.

The following actions were assigned:

Action 1/17/01-3: Determine who should be responsible for maintaining active on-orbit FIAR’s list and status.

Actionee: XA/D. Roberts

Due Date: 2/14/01

Action 1/17/01-4: Coordinate with I&O to develop procedures for tracking open FIAR’s to ensure that necessary action is taken at the earliest opportunity to bring hardware home, repair, etc.

Actionee: XA/D. Roberts

Due Date: 2/14/01
