13. H7190 — Remove EMU Softgoods Barcodes from FEMU-R-001 — ILC/Dave Cox

Due to the inadequacy of the current softgoods barcode design (Mylar film tearing during installation, barcode labels not adhering to Mylar film), an ISS IMS Barcode Label Request for Waiver was submitted and approved. The waiver was originally approved to be applicable through STS-108/UF1. Another request for waiver to extend the current waiver for approximately 1 year was approved. The following hardware is covered:

USA FCE/EVA has been writing DR’s on EMU softgoods scheduled to fly on Station. These DR’s were dispositioned "no constraint to flight" and the discrepant equipment flown with open DR’s. To alleviate the need for USA FCE/EVA to continually write DR’s against ISS EMU softgoods because they cannot be barcoded, this CCBD requests that the softgoods barcode requirement be removed from the FEMU-R.

A future CCBD will be submitted for the following:

• Incorporate the Teflon coated fiberglass (TCF)/Urethane style barcode assembly from the existing unapproved CCBD H7174, tentatively titled "EMU Softgoods Barcodes Fix".


• Generate an SED drawing and GCAR for the TCF/Urethane barcode.

• Remove the detailed procedures for both the hardgoods and softgoods barcodes from the FEMU-R.


• Create JSC controlled procedures to replace the procedures removed from the FEMU-R.

The absence of IMS barcodes on ISS EMU softgoods will not effect fit, form, or function of this equipment. This approach will cause an on-orbit tracking issue for ISS EMU softgoods.

The following action was assigned:

Action 11/7/01-1: Report to XA/Glenn Lutz within 3 weeks with a better story on the barcodes implementation.

Actionee: XA/Lara Kearney

Due Date: 11/28/01

Decision: Approve.

14. H-0696R2 — Reconfiguration of Bilateral Retractable Equipment Tethers — XA/Barbara Counts

This CCBD requests the reconfiguration of 4 flight retractable equipment tethers, P/N SEG33106164-381/-383/-385 to the small/large crew hook configuration P/N SEG33106164-361. The HST crew has requested a total of 6 and only 2 exist in inventory, which are already allocated to HST.

Decision: Approve.

This CCBD requests development of a new configuration of retractable equipment tether (RET), SEG33106164-TBD, a small/small crew hook with an added pip pin. The STS-109 wants to have a pip pin available for socket change outs and the most feasible configuration is a small/small crew hook RET with a pip, which does not exist. Equipment hook RET’s are the only configuration for the pip pin option. These hooks will not fit around flight-specific pieces of hardware that the crew must tether, i.e., MFR handle, old diode box, etc.). The crew’s mini-workstations are full with several tethers and cannot carry an unusable tether just to hold a pip pin.

The Board agreed on the following:

• There are enough drop proof tethers and extensions to accomplish the HST goals.


• The cost of full cert on a new tool is prohibitive at this time due to shortage of APA money.


• If redirected at a later date, the new hardware will be a certified configuration with both training and flight hardware.

Decision: Disapprove. This new configuration is only required to cover for a contingency case (failure of drop proof tether). Not needed.

16. H-1074R1 — EVA Cuff Checklist — EC5/Chris Tracy

This CCBD requests changes to the EVA cuff checklist as follows:

• Create new configuration with Nomex webbing in place of pile Velcro and with larger socket head cap screw in place of existing machine screw.


• Build 10 new cuff checklists less pages and 18 new units utilizing existing band covers.

EC5 will be the SSM to the hardware and will generate a CARD. MOD will maintain responsibility for the pages and spring that holds the band together.

The following actions were assigned:

Action 11/7/01-2: Generate an agreement with MOD on EMU cuff checklist responsibilities and report recommendations to the EEB.

Actionee: EC5/Craig Dinsmore

Due Date: 11/28/01

Action 11/7/01-3: Generate an ICD between the band and pages for the EMU cuff checklist.

Actionee: EC5.Chris Tracy

Due Date: 11/28/01

Action 11/7/01-4: Generate an ICD between the suit and the band for the EMU cuff checklist.

Actionee: EC5/Bill Spenny

Due Date: 11/28/01

Action 11/7/01-5: Work EVA cuff checklist quantities based on flight need, training need and Station need.

Actionee: XA/Margaret McPhail

Due Date: 11/28/01

Decision: Hold pending USA FCE/EVA cost impact.

This CCBD requests certification of 2 new on-orbit installed handrail (OIH) configurations for Node 2 on ISS 10A. It also requests a tolerance study to define the required seat track placement on Node 2, and definition (ICD) of the seat track installation requirements. The handrails must be OIH’s, as opposed to ground installed handrails, to allow for on-orbit removal during heat exchanger maintenance. The handrails obstruct the work volume and prevent necessary crew positioning. The custom lengths are required in order to preserve the existing load path through Alenia’s Node 2 secondary structure, which was originally designed for ground installed handrails.

Decision: Approve, pending receipt of exact dimensions from Alenia.

No further items were brought forward, and the EEB adjourned.
