Reliability & MSG-3 Processes – Theory & Practical – 5 Days


Reliability programs form an essential element of the continuing airworthiness process and in fact are mandatory when aircraft are managed using MSG methodology.

The purpose of a reliability program is to ensure that the aircraft maintenance program tasks are effective and their periodicity is adequate, in addition, the reliability program may result in the escalation or deletion of a maintenance task, as well as the de-escalation or addition of a maintenance task.

Whilst the primary purpose is to demonstrate the effectiveness of the Aircraft Maintenance Program, we can use the reliability program to support both the optimisation and development of the maintenance program.

Reliability data is also collected and analysed by the manufacturer as a tool to optimise the maintenance process and such information is typically considered by the MRB working groups.
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 actual reliability characteristics of the equipment they are designed to protect.

The course is developed to provide a practical approach to delivering an effective Reliability Program within the organisation and will be of immense benefit to anyone with responsibility for the reliability process or an obligation to perform audits of the reliability process.

Who is the Course for?

The course will also be beneficial to other persons working within a CAMO environment including Maintenance Program Management and Quality Audit Staff.

Target Groups

CAMO staff involved in managing the Maintenance or Reliability programs, Reliability Staff and other staff with technical involvement in the Aircraft reliability processes. The course is beneficial for persons requiring a comprehensive understanding of MSG-3.

The course will also be beneficial to other persons working within a CAMO environment including Maintenance Program Management and Quality Audit Staff.


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

Learning Objectives

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

This training covers all elements required to ensure you achieve the maximum benefit from your Reliability Program.
