3. 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

4. WHAT IS RCM? A Definition: Primary Objectives:
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

5. WHY DO RCM? New Programs: Legacy 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

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

8. 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

9. 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

13. RESULTS OF FMEA For each MSI: For each Function:
- 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
