EEB Board members from the following organizations participated:

XA/Chairman, XA/Secretary, XA/Tools and Crew Aids, XA/I&O, XA/Business Office, CB/Astronaut Office, DX32/EVA Systems Group, EA/Engineering, EC5/EVA and IVA Equipment, MV5/FCE, and NA/SR&QA.

The following items were presented:

Hardware Integration Schedule — XA/Rich Fair

Updates to the schedule include STS-108 (UF1) CEIT ship date completed 9/17/01, MPLM KSC Bench Review scheduled for 9/27/01, and STS-109 (HST-03B) PSA pull test scheduled for 9/25/01.

Space-to-Space Communication System (SSCS) Evaluation of CR H7003R1 (Expedited EMU Turnaround) — EV/M. Chavez

EV raised the following concerns of removing Space-to-Space EMU Radio (SSER) testing in conjunction with the Expedited EMU Turnaround CR H7003R1:

Limited SSER flight history

- Only one unit has seen more than one flight without rework

No verification of SSER caution and warning tones

- Failure to sound warning tone is a CIL with a Crit 2/1RB failure mode

Recommend adding verification of C/W tones to V1103.02

No verification of SSER transmit power and sensitivity

Key radio performance parameters that define communications range

Will not be preflight checked and would only be detectable during an inflight EVA

FIAR EV1268: Loss of SSER sensitivity is a constraint to implementing any EET that does not include SSER transmit power and sensitivity testing

Root cause has not been determined. Subassembly parts have been replaced but there is no known cause as to what happened. This could close as an "unexplained" anomaly.

The Board agreed to accept the risk of random failure and voiced no concern over lack of testing. The radio is certified for 25 launch/landings. The test EV performs only shows the hardware was good the last time it was used; it does not predict a failure.

The following action was assigned:

Action 9/19/01-1: Incorporate into V1103 procedures the ability to verify C/W tones.

Actionee: HSMS/Rob Boyle

Due Date: 10/10/01

PRACA Status — NS43/Terry Miller

Twelve A total of fourteen (14) FIAR’s are open for EVA hardware and are shown by flight as follows:

STS-100 (6A) 0

STS-110 (8A) 14

STS-111 (UF2) 14

Five FIAR’s were reported as past due. The following were statused:

JSCEC0881 — EHIP Lights. Flat washer permanently deforms when torqued and will not allow cap screw to maintain 5.0-inch pound torque value.

This FIAR closure is pending completion of the correct form.

BFCE029F105 — Pistol Grip Tool. Pistol grip tool chatter.

USA will have closure to PRACA by the end of the week.

A CR has been initiated and will be presented to the 9/24/01 EVA Tools and Crew Aids Panel.

JSCEC0871F — Waist Tether and JSCEC0872F — Safety Tether. STS-100 anomaly — Red indicator showing on load alleviator strap.

Closure is in work. A new ECD of 10/17/01 was assigned.

No new FIAR’s were reported.

The following STS-108 FIAR’s were statused:

JSCEC0781 — 5/16" Wobble Socket. Socket detaching from PGT during STS-103 EVA.

Final is in process; however, paperwork from OSS is late.

JSCEC0892 — HST Portable Foot Restraint. Pivot joint latch would not return under spring tension at the -150 deg. F test point.

Thermal testing has been completed.

No FIAR’s are open for STS-100.

STS-104 (7A) FIAR’s were statused as follows:

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

EC5/Roger Schwarz reported the hardware is going through vibe testing this week.

STS-105 (7A.1) FIAR’s were statused as follows:

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

EC5/Roger Schwarz reported this FIAR is still unexplained. The PGT will be shipped for MPLM Bench Review the end of the month. Interims will be written within the next 2 weeks. Hardware is to be left on-orbit.

The Chairman requested a note be added to the status to show dates interims are needed, shipping on open DR, etc.

The EVA hardware oldest FIAR, against the 5/16" Hex Wobble Socket, is 635 days old.

On-Orbit Limited Life Status — NS43/Terry Miller

The On-Orbit Limited Life Status was presented showing hardware expirations through 2/02. Items on the list include the MUT tool carrier, ORU transfer device, tether extension assembly, and trace gas analyzer.

A CR to extend the life of the MUT tool carrier will be initiated in 2 weeks. A CARD change for the ORU transfer device is in work for 8A.

Certification Status — NS22/Greg Wright

Open certification for STS-108 (UF1) includes the PFR bridge clamp, swingarm assembly, modular gimbal assembly, EHIP lights, and ORU transfer bags (large and medium).

There are 12 open certification items for STS-109. Certification for the MFR latches has been delayed due to a few manufacturing problems. Load testing is in progress. Paperwork needs to get to the SRP in order for the hardware to be at KSC by 10/12/01. This issue will be discussed with the Shuttle Program as there is no SRP scheduled until mid to late October.

Open certification items for STS-110 (8A) include the SAFER, SAFER IVA battery, SAFER inhibit plug and tool assembly, TERA base assembly, and MT energy absorber. TERA and MTEA certification is in work.

DX32/Peggy Guirgis was requested to inform DX32/Randy McDaniel that an E-mail outlining closure rationale to XA/Dale Roberts would be sufficient to close out the action.

Action 8/8/01-1: Update ICD to existing capabilities of tool. (ref: PGT torque tolerance discrepancy).

A PIRN update is required.

H7120 — EMU SSA Enhanced Small Boot Toe Spacer Certification and Implementation — ILC/Mike Pantaleano

This CCBD requests certifying and implementing the modified toe spacer in the enhanced small SSA boot TMG that was developed and evaluated under PPDO 00-2.2.3C-208. FEMU-R requirements for boot/foot restraint interface will be evaluated as part of this task and revised if necessary. Hamilton Sundstrand will revise manufacturing documentation and generate modification instructions to retrofit all delivered enhanced small SSA boot TMG’s (Class I and III). They will produce and deliver 14 pairs of toe spacers and 14 mod kits to support field retrofit of Class I and III enhanced small boot TMG’s, with delivery to USA on or before 2/12/02.

Decision: Route for technical concurrence.

Note: Hamilton Sundstrand was requested to specifically identify "the contractor" referenced in this CCBD as Hamilton Sundstrand (or HSSSI), ILC, USA, etc. This will be effective for all CCBD’s presently in work, and all future CCBD’s.

H7122 — EMU SSA Phase VI Restraint Ripstop Replacement Material Certification — ILC/Mike Hrycak

This CCBD requests certifying and implementing the Phase VI restraint incorporating the replacement ripstop material to 198 hours (20 EVA’s) based on the results of a 396-hour manned certification test.

Decision: Route for technical concurrence.

H7044R2 — EMU LSS CWS Redesign Effort/Procurement of Cert/Production Hardware — HS/Lenny Lacasse

This CCBD requests procurement of material to support caution and warning system (CWS) certification and production activities. This activity includes all EEE parts and mechanical details to assemble two CWS’s and two I-156 harnesses. The CWS inventory begins to expire in June 2003.

One concern voiced was the procurement of 100 pieces of the EEPROM for the CPU board, which are becoming obsolete. Hamilton Sundstrand assured the Board that they are pursuing other vendors/devices, but procurement of the 100 pieces will ensure hardware availability through life of the ECWS.
