- PRACA Status — NS43NS43/G. WrightTerry Miller
Fifteen A total of 18 FIAR’s are open for EVA hardware. Seven FIAR’s were reported as past due. The following were statused:
JSCEC0781 — 5/16" Wobble Socket (HST). Socket detaching from PGT during STS-103 EVA.
Closure paperwork is still with Contracts. Three more weeks will be required for closure. A new ECD of 8/27/01 was assigned.
JSCEC0880 — Top Mounted Passive WIF Assemblies. Anodized surface is tacky and paint is flaking off.
Per EC5/Kim Hostetler, the final closure write-up has been sent out for comments. Top mounted WIF’s DR’s are to be used "as is". Side mounted WIF are at EM for bakeout. A new ECD of 8/13/01 was assigned.
JSCEC0874 — T-Handle. STS-100 anomaly — sticky actuation of ball.
CLOSED. FIAR closure paperwork dispositioned to PRACA.
BFCE029F105 — PGT. Pistol grip tool chatter.
Per USA/Ryan McFadden, refurbishment is still in work. Closure rationale will be written as "unexplained". A new ECD of 8/13/01 was assigned.
JSCEC0860 — BRT. BRT will not stabilize after tensioning.
Per EC5/Roger Schwarz, DCN’s are in the system to call out the cleaning specification.
JSCEC0879 — PFR. HST PFR pitch joint pedal is not able to return to the lock position after actuation.
Per EC5/Roger Schwarz, this is a new problem that turned up during fix. A new ECD will be provided at the 8/8/01 EHB.
JSCEC0886 — Top Mounted Handrails. Discoloration found inside handrail bracket tube and powdery substance found to be aluminum oxide during PDA.
Per XA/Kristin O’Brien, it will take approximately 2 weeks to research where the other brackets have gone. Additional time will also be required for site visits and EM testing. A new ECD will be provided at the 8/8/01 EHB.
No new FIAR’s were reported.
One FIAR was listed as open for STS-105 (7A.1):
JSCEC0889 — MMWS Gimbal Assembly. Potential failure of screws.
CLOSED. FIAR closure paperwork dispositioned to PRACA.
There are 14 FIAR’s open for STS-108 (UF1). The following were statused:
JSCEC0851 — General Purpose Cutter. GPC handle does not lock within torque spec.
Per EC5/Roger Schwarz, a CR will be written in the amount of $50K with 6 months to finish redesign. The CR should be adequate rationale to close out the FIAR.
JSCEC0871F and -872F. Waist Tether and Safety Tether. Red indicator showing on load alleviator strap.
. Per EC5/Roger Schwarz, hardware was not built to print. The PIA to check assembly will be updated.
JSCEC0881 — EHIP Lights. Flat washer permanently deforms when torqued.
Per EC5/Roger Schwarz, washers are being built. A CR is needed to roll the dash number and close out the FIAR.
