UCx#46 Target handover from TPO 

Target insertion: successful 

Parasitic Install: All Parasitic targets left off target

• Left side In-beam array type parasitic install attempt #1 
  • Parasitic assembly is too thin/studs too tall for the socket nut to fasten onto target. Stud protrudes through the length of socket section, not allowing tool to insert 
  • previously a 3/4 spacer was used to give space for thermal couple to enter 
  • Install of 3/4 spacer was difficult because it does not hold its shape when handled (pivots around 1/2 ad 1/4 portions) 
  • With spacer installed, parasitic assembly is too thick for socket nuts to fasten onto studs. 
    • It may have been possible to back out studs to use, but left off in the interest of time UCx is exposed. 

• Right side In-beam window type parasitic install
  • Similarly to Left side, studs were too short for install, studs could be backed out, but was left off in the interest of time UCx exposed

• PEEK seal parasitic targets were left off as per schedule, and will be leak checked at another date (after tong cable has been repaired) 
  • Order of PEEK seal locations preserved and follows order as seen with target installed (Photo attached)

Target install: successful 

Leak Check: Successful 

Electrical Check: Successful 

• Initially failed due to wiring diagram being different between production wiring diagram and electrical test sheet
