Pathfinding Summary (1 of 2)
LAT Pathfinding Activity Documented in LAT-MD-07727
Objective: Identify and mitigate mechanical operations/handling risk.
• Pathfinder Lifting Operations
– Installation into and Removal from Shipping Container with the GPR.
– Installation into and removal from the Test Stand with GPR
– Onto and off of the Vibe Table with the GPR
– Test Stand Turnover with Complete Mass Simulator and SLAC lift
slings
– Installation of the rotated test stand and LAT onto the TVAC
table/Trolley
• Pathfinder Move Operations
– Transport weighted shipping container
– Move LAT in the test stand from clean tent to Sine Vibe.
– Move LAT and test stand from clean tent to EMI test chamber.
– Move LAT and test into Acoustic test chamber.
– Move LAT and test stand TVAC staging area and into chamber.
LAT-PS-07728 LAT Handling Procedure was developed during Pathfinding

Pathfinding Summary (2 of 2)
• Pathfinding Miscellaneous Operations/Installations
– Radiator installation/removal procedures including timed trial runs
(adhesive pot life)
– TVAC prep work – mount S/C simulator sink plate
– TVAC configure – another rotation and install on Table/Cart
• Improved handling procedures for installation and use of test
stand extensions
– Installation of TVAC STE – heater cages, ACD sink plates
– Transport into TVAC chamber and working around LAT and STE inside
chamber.
– TVAC cable installation and routing
Pathfinding activity mitigated potential risk for critical handling operations

I&T Operating Plan
• The detailed LAT I&T schedule is maintained in MS Project by the I&T Scheduler.
– Schedules will be updated daily via the afternoon meeting with progress from that day.
• NRL Operations
– Normal work time will be 7:00am-8:00pm. “Shifts” will run nominally 7:00am-4:00pm
and 12:00am-8:00pm. Shifts will be adjusted to go around the clock as the need
arises.
– Daily morning meeting at 7:00am and afternoon meeting at 3:00pm.
– Daily phone tag-up to SLAC at 4:00pm.
– Minimum staff when the instrument is under test is 2 LAT Electrical Test staff
members.
– TVAC will be staffed 24/7
– Extended shifts and/or Saturdays will be used to maintain schedule as required.
• LAT Instrument Handling
– LAT will be configured in the portable clean tent whenever possible.
– The LAT will be bagged to maintain cleanliness when outside of the controlled
environment.
– Cleanroom and ESD protocol will be maintained during all LAT handling operations.
NRL Operating plan is similar to SLAC Operations

Troubleshooting in I&T
• No troubleshooting will be done without appropriate disposition on an NCR.
• When an anomaly occurs:
– The test set-up is frozen
– The instrument and test equipment is safed.
– The test set-up and instrument configuration is reviewed and
documented by the Test Conductor.
– Test conductor notifies the TD, Subsystem Engineer and QA.
• QA initiates an NCR with information from TC and convenes MRB.
– At a minimum, MRB consists of the Test Director, Test Conductor,
Subsystem Engineer and QA.
• MRB will provide detailed disposition for troubleshooting.
• The test procedure will be redlined or a separate procedure will be written
(as defined by MRB) to document the troubleshooting activity defined in
the disposition.
Troubleshooting will be done in accordance with the I&T Implementation Plan
