  2. Documents on System Level • PACS-ME-PL-007, 2.0 ( PA Plan updated after IBDR) • IFSI/OBS/PL/2000-001 ( SW PA Plan ) - ready • Cleanliness Plan Issue 1 26.04.02 (submitted for signature - will be ready end of November incl. input of IBDR ) • HSO-SBT-TN-076 from 15/04/2003 (Safety) – ready • PACS-ME-PL-006 ( Configuration Management - update to be checked) • CIDL : PACS-ME-LI-011 ( update in progress ) PACS PA/QA IHDR

  3. ASTEQ : 18 open of 171 IMEC : 4 open of 21 KT : 2 open of 23 MPE : 29 open of 41 MPIA : 11 of 31 open CSL : 6 to be closed of 6 CEA : 1 open of 1 IFSI : nothing reported Cardiff : nothing reported IAC : nothing reported List available List available List available List available List available List available NCR Status PACS PA/QA IHDR

  4. NCR Status • Some remarks from PA/QA to NCRs: • -no major NCR reported about failures in DPU • -no major NCR reported about failures in Distribution Board • -open major NCRs about detector modules - • which are going to be assembled in CQM • These NCRs cannot be closed without identification of failure causes and corrective and preventive actions PACS PA/QA IHDR

  5. Missing or misunderstood documents • Critical Item List : new technology, components used out of spec, • not qualified parts, parts from unqualified sources • single point failures identified in the FMECA • 4x available – 5x missing • FMECA updates : all FMECA based work (FDIR) makes no sense • if FMECA is not kept up to date • Materials List A lot of these lists are available, but • Mechanical Parts List there is a real creative naming and • Process List fragmentation. Handling of all subsystems • EEE Parts List takes time. A unification would be helpful. PACS PA/QA IHDR

  6. HSIA : there is a simplified ESA-acceptable approach, which I have sent to all . • ( Missing : all - except CSL ) • Doc. : SPIRE-RAL-NOT-001719 PACS PA/QA IHDR

  7. Ongoing Lists • Request for waivers : 7 in process ( List available) • Change requests : 15 in process ( List available) • PADs : 23 in process ( List available) PACS PA/QA IHDR

  8. PA/QA Documentation System-outlook- • PACS documentation is very complex due to many different supplier systems. • To come to an easier handling, an unification should be done now and also to come to a reduction wherever it is possible. • Precondition: Workshop with all PA/QA responsibles and if possible with ESA attendance. • This input will pay off in money, in time and in understanding the • PA/QA subject. • We should have asap a discussion and an agreement about this proposal. PACS PA/QA IHDR

  9. FMECA • Status: • PACS-ME-GR-004 draft (2) 07 Feb 2002 • Updates available from: missing from : • IFSI - IAC • KT - CEA • MPIA • CSL • ( Remark: Updates should be done in the original Excel file!!) • (Remark: Availability does not imply usability in each case ) PACS PA/QA IHDR

  10. Single Point Failures • On the base of ranking of criticality due to FMECA • 11 single point failures are identified. • (most of them refer to the chopper) • SPFs are listed in CIL. • PA/QA has to check succeeding actions. PACS PA/QA IHDR

  11. Critical Items • Black paint cryoqualification (outgassing open) • Assembly and testing of detector modules • Gold plating process of foreoptics • Qualification of distribution board PACS PA/QA IHDR

  12. How we should continue... • Cooperation with PA/QA partners has improved continuously, but with upcoming deliveries of hardware it is necessary to go on with a close teamwork. • Each subunit should be able to audit its processes and inform • PACS Project about all deviations asap. • Especially incoming and outgoing inspections must be done strictly and well documented.
