Issues & Concerns
• Timely and Appropriate review of Documents
•
CAL Interface (CAL-LAT IDD LAT-DS-00233 Rev 07)
– 4 weeks to receive comments.
•
ACD Interface (ACD-LAT IDD LAT-DS-00309 Rev 04)
– Check print sent out for review, 9/22, waiting for feedback
•
MLI Blanket Design
– Conceptual design still in review by Spectrum
– The only feed back received since 9/7/04 is a request for additional drawing views on
10/28
– Note the additional work to provide views was not planned until conceptual design
approval was given.
•
Instrumentation
– Detail design of cabling over 50% complete, cooperation between subsystems is required
– Issues still open from last month
•
•
•
Instrumentation Termination Bracket design definition
Specific locations and mounting methods have been defined, need to be reviewed
Still need detail harness definition for accelerometers
