1. PACS 12/13 November 2003 PACS PA/QA IHDR1 PACS PA / QA STATUS Documentation overview Cooperation with PA/QA responsibles -outlook- NCR Status System documents Missing documents Ongoing papers (RfW,PAD,CR) Outlook Documentation FMECA Single Point Failures Critical Items Outlook PA/QA

2. PACS 12/13 November 2003 PACS PA/QA IHDR2 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 )

3. PACS 12/13 November 2003 PACS PA/QA IHDR3 NCR Status 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

4. PACS 12/13 November 2003 PACS PA/QA IHDR4 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

5. PACS 12/13 November 2003 PACS PA/QA IHDR5 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.

6. PACS 12/13 November 2003 PACS PA/QA IHDR6 HSIA : there is a simplified ESA-acceptable approach, which I have sent to all. ( Missing : all - except CSL ) Doc. : SPIRE-RAL-NOT-001719

7. PACS 12/13 November 2003 PACS PA/QA IHDR7 Ongoing Lists Request for waivers : 7 in process ( List available) Change requests : 15 in process ( List available) PADs : 23 in process ( List available)

8. PACS 12/13 November 2003 PACS PA/QA IHDR8 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.

9. PACS 12/13 November 2003 PACS PA/QA IHDR9 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 )

10. PACS 12/13 November 2003 PACS PA/QA IHDR10 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.

11. PACS 12/13 November 2003 PACS PA/QA IHDR11 Critical Items Black paint cryoqualification (outgassing open) Assembly and testing of detector modules Gold plating process of foreoptics Qualification of distribution board

12. PACS 12/13 November 2003 PACS PA/QA IHDR12 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.
