What is Maintenance Steering Group-3 (MSG-3)?

MSG-3 is a structured methodology used in aviation for developing maintenance programmes. It aims to optimise maintenance efforts by focusing on the functions and failure modes of aircraft systems rather than specific components. MSG-3 categorises maintenance tasks into three groups: on-condition maintenance, hard-time maintenance, and failure-finding maintenance. This approach helps to ensure that maintenance is performed at the most efficient intervals based on the criticality of the systems and the likelihood of failure. MSG-3 is widely used in the aviation industry to enhance safety, reliability, and cost-effectiveness in aircraft maintenance programmes.

Course Overview

The course provides delegates with an insight in the principles of MSG-3 which is a structured process for identifying Safety Significant Items (SSI), the defining for each SSI the failure modes and effects (FMEA). A decision tree is then applied to decide the maintenance strategy for each SSI.

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

  • This course is suitable for individuals working in, or with oversight of the Continuing Airworthiness Management of all aircraft types. It is equally suitable for both commercial and non-commercial owners and operators.
  • National Aviation Authorities: In particular, staff members having duties and responsibilities in line with the scope of this course

This training course will include the following topics:

  • What is MSG 1 / 2/ 3? Why was MSG developed? How does MSG work in Aircraft Maintenance? When was MSG introduced?
  • How does MSG 3 compare with MSG2/MSG1?
  • ICAO and EU regulations on MSG
  • Maintenance Steering Group (MSG) Analysis methodology
  • How MSG-3 which is a task-oriented methodology is used to derive scheduled maintenance requirements.
  • How MSG 3 delivers a top down approach which focuses on the need to ensure either economic viability or to maintain the aircraft system, component or structure in an airworthy condition.
  • How for each potential failure cause, the MSG-3 guidelines provide task-oriented logic to determine the appropriate scheduled maintenance tasks
  • What are Maintenance significant items (MSI’s) in MSG 3
  • Consequences of failure approach – either safety or economics. Distinction between failure evident to or hidden from operating crew.
  • How MSG 3 Improves MRB Maintenance Programme Development

By the end of this course, delegates will demonstrate understanding of the Maintenance and Reliability Programmes with the use of practical exercises, review of case studies, and group discussions.

This course aims to provide the participants with an understanding of the principles of MSG-3 process and methodology employed to develop MSG-3-based Maintenance Programmes.

Delegates should have experience in Continuing Airworthiness or Maintenance Management and have a working knowledge of Part M / Part CAMO.

A background in an aviation maintenance planning and reliability will be a distinct advantage however the course is stand alone.

Delegates should review the Part M regulation and its Subparts. Delegates should also review existing Aircraft Maintenance Programmes and Reliability Programmes to get an understanding of the MSG 3 process used in the evaluation of systems and inspections.
