Maintenance Steering Group-3 (MSG-3) is a document developed by the Airlines For America (A4A) that presents a methodology to be used for developing acceptable scheduled maintenance tasks and intervals.

This advisory circular (AC) provides guidelines that industry may use to develop and revise the minimum scheduled tasking/interval requirements for derivative or newly type-certificated (TC) aircraft and powerplants for Federal Aviation Administration (FAA) approval.

MSG-3 was first published in 1980 is a task orientated and the main idea behind this concept is to recognize the inherent reliability of aircraft systems and components, avoid unnecessary maintenance tasks and achieve increased efficiency.

2021年3月25日 · Maintenance Program tasks are developed using an MSG-3 based, guided logic approach and result in task-oriented programs. Maintenance task development starts with identification of Maintenance...

2021年8月24日 · Underlying Principles of MSG-3 Aviation Maintenance According to Skybrary, the main idea behind the MSG-3 concept is to recognize the inherent reliability of aircraft systems and components, avoid unnecessary maintenance tasks and achieve increased efficiency.

Just as each subsequent aircraft design introduced new enhancements, each revision to the logic for developing maintenance programs provided a somewhat better approach. The latest of these revisions is known as MSG-3. (1) * DOI: https://doi.org/10.4271/841481. Citation: Nakata, D.,

The ATA MSG-3 publication outlines a decision-logic process for determining initial scheduled maintenance requirements for new fixed-wing aircraft and/or power plants. This document presents a means for developing maintenance tasks and intervals acceptable to regulatory authorities, operators and manufacturers.

MSG-3 provides guidelines for systems and powerplant analysis, aircraft structural analysis, zonal analysis and lightning/high intensity radiated field (L/HIRF) analysis.

MSG-3-based maintenance programs are readily adaptable to hierarchical maintenance concepts, the process of rolling up all lower-level core inspection requirements into the next higher inspection interval.

2021年3月8日 · MSG 3 recognises the inherent reliability of aircraft systems and components, moreover it avoids unnecessary maintenance tasks and achieve increased efficiency. MSG 3 is the process which is used to generate the Maintenance Review Board Report – MRBR.
