GSC suspected - what GSE? • ET hard-mated @ 0600. Strut clearance problem w/ insulation on [[strikethrough]] Work [[/strikethrough]] SRB side. ¨~4HRS down • RMS EE: SPAR/JSC requested 5 day shp in delivery date for mod. Cohen Approved - Due KSC on 16th • FC run of 4-5 hrs to be done on pad during tanking test • PBD FRSI to be pulled back for enough to verify bonding of melted tab that holds thermal barrier to composite structure. No high-priority placed on this @ present (due prior to roll-out) • Aft fuselage sample bottles - data indicates 3-fold increase in leakage rate between STS-1 4 2 (6500 SCM^3). New leak checks ordered. Heat shield installation constraint • RCS ullage P (L FU ULL) was found to be ~309 PSI Greater than < 100 PSI nominal) @ power-up Yesterday. Burst disks rated ~312.

Horace Lambert 2769 Burst-Disks verified as not ruptured. • MMU IPR- holding off on R/R. RI-KSC Art Edison design designee doesn't feel its a problem worthy of removal. RI-DPS, JSC, RI-DNY all feel strongly it should be removed. Suspected wear problem on polished surface tape is drawn across; tape didnt get up to speed during load.
