EASA Part M – Understanding MSG 3 Methodology and Analytic Process Fundamentals – 2 Days


In 1979 the Air Transport Association (ATA) task force sought to improve on MSG-2 to address a new generation of advanced technology aircraft (B757 & B767), the outcome was MSG-3.

MSG-3 is now the preferred method used for developing the scheduled maintenance tasks and intervals which will be acceptable to Regulatory authorities, Operators, and Manufacturers.

MSG 3 delivers a top-down approach that focuses on the need to ensure either economic viability or to maintain the aircraft system, component, or structure in an airworthy condition.

For each potential failure cause, the MSG-3 guidelines provide task-oriented logic to determine the appropriate scheduled maintenance tasks. The resulting task-oriented program consists of specific tasks, selected for a given functional failure consequence based on the actual reliability characteristics of the equipment they are designed to protect.

Tasks are selected in a hierarchy of difficulty and cost, from lowest to highest. Depending on the consequence of failure (safety, operational, economic, hidden safety, and hidden non-safety) a single or combination of tasks will be selected.

This course provides an opportunity to understand the scope and functionality of MSG3 process and how it relates to the development of the Maintenance Review Board Report.

Who is the course for?

All personnel with duties and/or responsibilities in the Airline Planning environment. Quality Assurance Staff. Also of Interest to persons working in a CAMO or Part M Quality System. Production Planning and Reliability Specialists, Engineers, Managers & Lease Companies.
