November 17, 2004Tracker2 Tracker Estimated Cost at Completion Actual Cost of Work Performed (ACWP), end of September ‘04$15,155,000 September outstanding commitments$1,537,000 Professional Services still to go (COI, Parlex, Tackes, etc.)$230,000 Travel forecast$143,000 Budgeted Cost of Work Scheduled for Labor through July ’05$492,000 Stellar Solutions Manpower (CR 4837)$552,000 Estimated liens$2,467,000 Estimated cost at completion (sum of all lines above)$20,576,000 Current budgeted cost at completion$17,126,000 Estimated overrun (difference of the above 2 lines)$3,450,000

November 17, 2004Tracker3 Liens Tungsten tile etching and priming at GSFCQuote$138,000 Introduction of new processes at Teledyne (bakeout, ESD ionizers, etc) Quote$73,000 Payment to Teledyne for MIP-1 failures due to CFMQuote$40,000 Increase term for source inspector at TeledyneQuote$53,000 More pitch adapters for MCM productionEst.$42,000 More Omnetics connectorsQuote$127,000 Purchase surplus SSDs from HamamatsuPO$62,000 More carbon-carbon closeout materialEst.$30,000 Out-of-house work required because of safety stand-downEst.$50,000

November 17, 2004Tracker4 Liens Overrun on flex-circuit cables (incl. 2 nd source)Wag$290,000 Various GSE, and upgrade to the CMM area (next slide)Est.$34,000 TQCM for T/V testingQuote$27,000 Sidewall prepregQuote$16,000 EMI testingWag$50,000 Continuation of Stellar Solutions labor through Sept.Quote$330,000 Continuation of SLAC over-budget labor through Sept.Est.$855,000 Misc. parts and materials to support Italian productionWag$150,000

November 17, 2004Tracker5 GSE Items Tower support stand$10,000 TEM/PS support$1000 Dark box$1000 Lifting hoist$5000 Lift sling$1000 Cable bending tool$5000 Pitch-adapter test fixture$3000 Upgrade to CMM area for contamination control$8000

November 17, 2004Tracker6 Descopes Build only 16 or 17 flight towers? –Tower-0 used up a lot of flight material that we have to replace if we want to build the 18 th tower. –We are having yield problems with other parts, in particular the MCMs. This potentially could require painful actions such as making more ASICs in order to built 18 more towers. We are already going out to purchase more long-lead material such as the carbon-carbon for tray fabrication, and we are considering building more bottom-tray closeouts (all U.S. expense). –Tower-0 probably could be refitted to make an acceptable beam-test tower by replacing or reworking the layers that are dead using good, but non-flight parts. –Such a beam-test tower would not require environmental testing, resulting in some more savings.
