MSG3 Maintenance Programme Optimisation

WHY MSG3?

  • 50% reduction in preventative maintenance man-hours / vehicle / maintenance cycle
  • 300% increase in miles between technical failure in-service
  • Significant reduction in maintenance errors

IMPROVED FLEET AVAILABILITY & IN-SERVICE RELIABILITY

MSG determines where maintenance can reduce the likelihood of system failure and structures a maintenance regime, which enables proactive intervention before system degradation can impact operations.

REDUCED MAINTENANCE COSTS

MSG only recommends a maintenance intervention if it will improve system reliability, supporting the removal of tasks which do not contribute to train performance or reliability improvements.

UNDERPINS THE TRAIN SAFETY CASE

The primary purpose of MSG3 is the identification of system and / or component failures, which could impact safety; and requires a maintenance intervention or re-design to prevent the harmful consequences of failure.

WHAT IS MSG3?
Maintenance Steering Group Logic (MSG3); is a hierarchical, ordered, logic based process to derive a minimal, safe maintenance programme. It is used as the basis for maintenance programme design on almost the entire worldwide fleet of commercial aircraft, some 25,000 hulls. It creates a highly structured programme, clearly identifying tasks associated with safety, performance, or economic drivers.

MSG3 is a sophisticated, highly developed approach to maintenance programme design. The MSG process is primarily used to develop the systems based element of the programme; in an aviation context the vehicle will also have a Structural Inspection Programme (SIP) to manage fatigue and damage tolerance, and an Environmental Deterioration Programme (EDP) with specific corrosion prevention and ageing systems methods. Together, these make up the full and approved Aircraft Maintenance Programme (AMP) for which, the MSG3 analysis forms the base document.

CROSS INDUSTRY TRANSFER

We are concerned here with the MSG systems related maintenance, which is most transferable to rail. Generally, damage tolerance and fatigue management is less of a concern, however, environmental deterioration and corrosion prevention is something to be considered.

MSG can be used to design and support any structured maintenance programme requirement and is particularly suited to safety critical applications, where the identification of safety derived maintenance tasks are important.

PROVEN APPLICATION IN ROLLING STOCK MAINTENANCE PROGRAMME DEVELOPMENT

We have successfully applied MSG3 to rolling stock with proven enhancements in unit reliability, together with significant reductions in the preventative maintenance plan and corresponding man-hours.

Before the application of the MSG3 process, considerable redundant actions had become embedded in the fleets’ maintenance programme, which together with a lack of historic (FMEA) data to support their inclusion, made it difficult to justify their removal using any other system. MSG3’s well-proven processes provided a mechanism to safely and justifiably change the baseline programme.
