The EVA Tools and Crew Aids Panel met at JSC on August 13, 2001, in Building 1, Room 360, at 1:00 p.m. Representatives from the following organizations participated:

EVA Project Office

Hardware Development

Integration and Operations

Engineering Directorate

Crew and Thermal Systems Division


Safety, Reliability and Quality Assurance Office

Hamilton Standard Management Services

Lockheed Martin

Panel members from the following organizations participated:

XA/Panel Chair, XA/Panel Secretary, XA/I&O, DX32/EVATask Group, XA Integration and Operations, CB/Astronaut Office, EC5/Crew and Thermal Systems Division, FCE/EVA, and NA/SR&QA.

The following items were presented:

  1. PRACA Status — NS43NS43/G. WrightTerry Miller

Fifteen A total of 18 FIAR’s are open for EVA hardware. Five FIAR’s were reported as past due. The following were statused:

BFCE029F105 — PGT. Pistol grip chatter.

Testing is complete and refurbishment is done. USA will provide an updated status to the 8/15/01 EHB.

JSCEC0880 — Top Mounted Passive WIF Assemblies. Anodized surface is tacky and paint is flaking off.

WIF need dates are still to be determined. The virtual work authorization record (VWAR) is in the EM signature loop. An updated status will be provided to the 8/15/01 EHB.

JSCEC0883 — Portable Foot Restraint. While performing PIA, the roll push button was sticking.

Thermal testing has been deferred to later this week (will combine with other hardware to save money). A new ECD of 8/20/01 was assigned.

JSCEC0885 — Small QD Bail Lever. The 1" end of the QD bail lever does not fit correctly to the interfaced QD in the valve open position.

The redesigned lever is to be fitchecked at KSC next week. A new ECD of 8/27/01 was assigned.

BFCE026A026 — Modular Gimbal Assy, MMWS. _ -20 modular T-bar screws inadvertently disengaged the retractor assembly.

EC5 will write final closure with plan of action by 8/20/01.

This FIAR was written against training hardware. The Chairman questioned how USA would handle non-flight discrepant hardware. The following action was assigned:

Action 8/13/01-01: Provide plans to resolve discrepancy with MMWS training hardware and plan to prevent inadvertent release of retractor assembly from gimbal assembly.

Actionee: USA/A. Knight

Due Date: 8/20/01

No new FIAR’s were reported.

The following UF1 FIAR was statused:

JSCEC0886 — Top Mounted Handrails. Discoloration found inside handrail bracket tube and [powdery substance found to be aluminum oxide during PDA.

Site visits to inspect hardware are still being organized. Participants from Quality, EC5 (Lockheed) and XA will be in attendance.

While attempting to have some of the potentially discrepant top mounted handrails returned to JSC for testing, it was discovered that there was no official notification to other field centers to tag suspect hardware and therefore no official direction to have hardware returned for inspection. The Chairman questioned if there was a method of identifying discrepant Space Station hardware. According to SR&QA/Greg Wright, the ISS electronic PRACA system is used to open FIAR’s on ISS hardware and is similar to the Shuttle PRACA system. NA/Chris Rodriguez will check on this process and report findings to the EVA Tools Panel.

JSCEC0887F — On-Orbit Installed Handrails. Handrail could not be installed on airlock seat track interface.

Per EC5/David Glebe, The 7A hardware is back, but has not been looked at yet.

During the 7A Crew Debrief it was discovered that the crew was in violation of procedures when installing handrails. This will be brought to the attention of XA/Glenn Lutz and an action assigned at the 8/15/01 EHB.

Preliminary closure in work. Still had chatter on 5A. Look at closing "as is".

EC5/B. Greene presented a FIAR Status on JSCEC0853F — Bayonet Receptacle.

STS-92 and STS-98 crew experienced excessive loads required to remove hardware from Bayonet Receptacles on the Modular Mini-workstation T-Bar and Swing Arms.

The following STS-104 FIAR’s were statused:

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

Going to vendor end of March to get root cause closure.

JSCEC0841 — PFR Gimbal Assembly. Roll joint buttons binding.

Need to get with EM for root cause.

JSCEC0842 — Modular MWS Gimbal Assy. Fraying of end effector cord.

In work. Cost substantial.

JSCEC0781F — 5/16" Wobble Socket (HST). Socket detaching from PGT during STS-103 EVA.

Funded. Design change complete. Close out.

JSCEC0848F — Equipment Hook. Inadvertent equipment hook release.

Should have final by next week.

JSCEC0850 — Safety Tether. Discoloration of safety tether.

Test results by 3/19/01.

The following STS-104 SAFER FIAR was statused:

JSCER0035 — USA SAFER. SAFER battery erratic current readings.

Currently on-orbit. Will not get back until 6A lands. Will need month to do assessment.

The EVA hardware oldest FIAR, opened against the 5/16" hex wobble socket, is 600 days old.

FIAR’s open by flight:

STS-102 0

STS-108 (UF1) 12

STS-109 (HST) 17

STS-110 (8A) 17

STS-111 (UF2)` 17

  1. Cert Status — NC52/Greg Wright

All certification is closed for STS-102.

There are three open SAFER hardware certifications for STS-100 — 2 on the SAFER IVA Battery (-305 and -307), and SAFER Battery upgrade. These are pending GCAR updates for closure.

There are 22 open hardware certifications for STS-104, all "green".There are three open hardware certification items for STS-108 (UF1). Cert on the PFR bridge clamp is due to S&MA 8/30/01. The ORU transfer bags have ship dates of mid-September. There are 13 open hardware certification items for STS-109, with most requiring ESEL updates to close. Open hardware certification items for STS-110 (8A) include the SAFER, SAFER IVA battery, and SAFER inhibit plug assembly. Due date to S&MA for these items is 1/11/02.

  1. Mission Hardware Status — LM/F. BlissFred Bliss

The following Mission Hardware Status was presented:

STS-102: All hardware has been delivered for flight.

STS-100: STS-98 hardware was received from USA on 3/2/01, and is being processed for the STS-100 Bench Review on 3/16/01. Roughly 20% of Bench Review hardware has been shipped. The other hardware will be sent as it is processed.

STS-108: Two pieces of MPLM flight hardware added 8/6/01 were delivered to USA on 8/8/01 for shipment to KSC. The majority of serial numbers for the payload bay ship have been found. Some items that are needed from STS-104 still have not been returned. A list of the CEIT hardware is still needed so this hardware can be processed, along with the payload bay hardware.

STS-109: Tools are being gathered to perform functionals so hardware can be shipped for the 4th HST crew Fam scheduled for 8/27/01. Some hardware, such as some HST sockets will not make this Fam because they are being reworked. Functionals have been performed on some of the HST Crew Fam #4 hardware.

  1. Actions Review — XA/G. LeStourgeonDale Roberts
  2. No actions are due.

  3. Pending CR Review — XA/G. LeStourgeonGreg LeStourgeon

There are no CR’s pending.

  1. HITS Status Review — XA/Jackie Manning

The weekly "stoplight" HITS Metric Report was presented. This report shows hardware and/or service/

support delivered, on schedule, and not meeting planned delivery date or program need date. Showing "Red" for STS-108 are the LMC handrail and WIF due to an open FIAR on the hardware. ORU transfer bags delivery date may move to October; this will be reviewed with the XA Hardware Manager.

This item was deferred.

  1. Gage Status — EC5/Kim Hostetler
  2. The monthly Gage Status was presented. This status shows gages that are new and in calibration, gages that will expire in 4 months, in for calibration, gages that will expire in 4 months, not in for calibration, expired gages in for calibration, expired gages not in for calibration, and gages with TBD or no calibration.

    The Lockheed inspection vendor survey had positive responses returned by eight of the 12 vendors surveyed. Lockheed will pick two to three of the JSC-preferred vendors. The JSC Cal Lab will be in the coordination loop.

  3. H-1025 — Change Flight Equipment Tether S/N — EC5/David Glebe

This CCBD requests re-serializing top assembly flight equipment tethers to a 4000 series S/N in order to prevent duplication of S/N’s of flight and training equipment tethers.

Decision: Route for technical concurrence.

  1. H-1002R1 — Update Russian Launch ESEL for Progress 5P — XA/Chuck Fulcher
  2. Revision 1 to the Russian Launch ESEL for Progress 5P adds items launched on Russian vehicles to the NASA ISS On-Orbit ESEL.
