MAINTENANCE ENVIROMENT WITHIN RCAF • Maintenance Program part of Design • Changes tightly regulated • Conduct of Maintenance on aircraft / equipment recorded and controlled • Support to Legacy fleets becoming more challenging OMUG 2013 M. Martin 3

WHAT IS RCM? A Definition: – RCM is a structured process to identify the appropriate level of preventive maintenance for an item to: • Retain inherent levels of performance, reliability and safety • Minimize cost of maintenance and failures over the life cycle Primary Objectives: – Ensure safety through PM actions; when PM cannot effectively ensure safety, redesign is mandatory – When safety is not a concern, preserve functionality in the most economical manner with the least impact on Operations OMUG 2013 M. Martin 4

WHY DO RCM? New Programs: – Requirement of design (ICAs) – Identify APPLICABLE and EFFECTIVE scheduled maintenance tasks – Initial programs conservative and generic Legacy Programs: – Able to modify generic programs to suit environment and fleet performance – Structured, disciplined approach to substantiating proposed Design Changes OMUG 2013 M.

STEPS TO PERFORM RCM Step 1: Step 2: Step 3: Step 4: OMUG 2013 Identify MSI Perform Functional FMEA Apply MSG-3 Decision Logic Level 1 – Failure Effect Code Level 2 – Task Identification Package Maintenance Tasks M. Martin 7

MAINTENANCE SIGNIFICANT ITEMS (MSIs) – Objective of MSI selection: select appropriate systems / components for analysis – Why be selective? • A/C equipment and systems have many components and parts • Analysis of every component on an aircraft would be unrealistically costly and time consuming • Failure of many items have no immediate impact on the a/c as a whole – RCM derived maintenance program directs tasks where they matter – at Significant Items OMUG 2013 M. Martin 8

STEP 1 – IDENTIFY MSIs – Partition equipment into major functional areas – Top-down approach; identify items at highest manageable level – Item is MSI if failure could: • adversely effect safety • Have major operational or economic consequences • Be undetectable during normal operations – If in doubt, item should be selected as an MSI OMUG 2013 M.

STEP 2 - FUNCTIONAL FMEA OMUG 2013 M. Martin 12

RESULTS OF FMEA For each MSI: - List of High Level Functions For each Function: - List of Functional Failures For each Functional Failure: - List of Failure Effects For each Failure Effect: - List of Components which cause this Functional Failure/Failure Effect to Occur OMUG 2013 M. Martin 13
