Decision: Route for technical concurrence.

10. H-1055 — Baseline STS-113 (11A) Tools ESEL — XA/Barbara Counts

This CCBD baselines the STS-113 (11A) Tools ESEL. It contains post-ISS airlock tools quantities, the Tether Shuttle, CETA cart and passive/active CETA couplers as mission specific items, and the lightweight port TSA.

Decision: Route for technical concurrence.

11. H-1026 — Baseline Russian Launch ESEL for Progress 6P — XA/Chuck Fulcher

This CCBD baselines the Russian Progress 6P ESEL. It contains Orlan suit components, joint airlock components, experiment components, and miscellaneous hardware.

  8. This CCBD requests updating the CARD and ICD for the BRT to specify the acceptability of attachment of a 300 lb. ORU to the ISS EMU using a BRT via the modular baseplate assembly.

    Decision: Route for technical concurrence.

    H-1058 — SM Debris Panel Temp Stowage Device — Provide ROM and Schedule — XA/Tara Jochim

    This CCBD requests EC5 to provide a ROM and schedule to build and certify a device to temporarily stow the service module debris panel (SMDP) bundle on the U.S. segment. The stowage method will be similar to the current temporary stowage of STRELA on an APFR on PMA1. The new hardware will be a combination of U.S. and Russian built hardware. The Russians will provide a magnetic socket to interface with the U.S. built section. The U.S. built section must interface with an APFR tool stanchion socket. The mass of the SMDP bundle will be 150 lbs, with the assumption that the bundle will be subjected to acceleration loads of 0.2g.

    A question of who would certify this hardware was raised. It was the decision of the Tools Panel to provide the TS probe from 2A FSE with certification and ship to Russia.

    Decision: Route for technical concurrence.

  9. H-0749R2 — SAFER On-Orbit Trainer — ER/P. McCartney
  10. This item was deferred.

  11. Fastener Locking Requirements and Practices — ES4/Rajib Dasgupta

ES4 presented fastener locking requirements for JSC flight hardware. These requirements will be incorporated into JSC-28484, Program Requirements Document for Johnson Space Center (JSC) Non-Critical Government Furnished Equipment (GFE), currently undergoing revision. Specific requirements are as follows:

  • Fasteners shall have two separate verifiable locking features. At least one shall be positive locking and vibration rated.

  • Joints subject to rotation shall use at least one non-friction locking device.

  • Installation procedures shall require functional verification of locking feature, such as measurement of running torque or visual inspection of lockwire integrity.

  • Preload and running torque shall be specified on the drawing. Exceptions shall be documented via GCAR.

  • Locking compounds (Vibratite or Locktite) shall not be used without prior approval from JSC Structural Engineering Division.

Safety critical fasteners were defined as those fasteners, which if a failure occurs could result in a critical or catastrophic hazard due to joint separation or release of debris (that causes contamination, crew injury electrical short or a fire hazard).

Recommended methods of locking and examples of positive locking devices were also presented, as well as requirements for non-safety critical fasteners and secondary locking methods.

These requirements are for new hardware only. ES4/Materials Branch has requested prior approval be obtained before Vibratite or Locktite (or other non-verifiable locking compound) is used.

No further items were brought forward, and the EVA Tools and Crew Aids Panel adjourned.
