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 WIFs DRs 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.

JSCEC0886 Top Mounted Handrails. Discoloration found inside handrail bracket tube and powdery substance found to be aluminum oxide during PDA.
Per XA/Kristin OBrien, 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 FIARs were reported.
One FIAR was listed as open for STS-105 (7A.1):
JSCEC0889 MMWS Gimbal Assembly. Potential failure of screws.

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.
