ASD/AIA S 3000 L Steering Committee (S 3000 L_SC 01) 11. 04. -14. 04. 2011 – Paris, GIFAS S 4000 M – History of development Cassidian Air Systems 1

ASD S 4000 M Scheduled Maintenance Analysis The specification S 4000 M is designed to cover the activities of a Scheduled Maintenance Analysis (SMA) process The concept of this specification was originated in 2006. 24. 06. 2009 Publication of S 4000 M, Issue 0. 1, in Brussels 2010 Commenting phase and harmonization with international organizations (e. g. ATA, MSG-3 group) 12/2010 End of incorporation of comments (ca. 50 -60 extended technical comments) 01/2011 End of editorial finalization of issue 1. 0 ? ? /2011 Publication of issue 1. 0 (depends on ATA/MSG-3 related constraints) 2012 Issue 1. 1 with new chapter OPM (Optimization of Preventive Maintenance during in-service) (together with ASD/AIA S 3000 L) 2

ASD S 4000 M Scheduled Maintenance Analysis - Content The specification S 4000 M is designed to cover the activities of a Scheduled Maintenance Analysis (SMA) process Specification is devided in 3 main chapters plus one chapter in preparation: • System and powerplant analysis • Structure analysis • Zonal analysis • Optimization of Preventive Maintenance (OPM) - new 3

FC = Failure Cause EFC = External Failure Cause ASD S 4000 M Identification of critical failures / failure causes of a system end effects ASD S 4000 M MSG-3 (zivil) Top Down investigation of failure effects and validation of failure MSG-2 (civil), RCM (military) next higher effects Advantage: also external failure causes are considered Bottom up investigation of failure causes failure effects The considered failures can be relevant for: Safety Ecology and law Mission and operation Economy S 4000 M, MSG-3 and RCM new in S 4000 M ! S 4000 M, MSG-3 and RCM relevant for certification relevant for qualification (acceptance) 4

ASD S 4000 M Structure of S 4000 M chapters Chapter V Chapter I Definitions and abbreviations Introduction Chapter II System and Powerplant Analysis Chapter III Chapter IV Structure Analysis Zonal Analysis Remark: Zones MSG-3 and RCM analysis show gaps concerning Structure and Zonal Analysis. often specific rules and extensions must be implemented for projects (e. g. by a Project Procedure Handbook - PPH for A 380 at Airbus) 5

ASD S 4000 M and OPM (Optimization of Preventive Maintenance) Operational data basic information for OPM activities OPM process will be integrated into S 4000 M as an own chapter (in the next issue). Adjustment of Scheduled Maintenance because of OPM results Documentation of original results of SMA as LSA tasks with interval, MTA und packaging of the tasks Maintenance concept ! IMPORTANT ! In the LSA database, the complete view on scheduled maintenance is documented: Single tasks with original interval / packaging / OPM adjustment (traceability to original task is guaranteed by complete documentation within LSA database) 6
