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.

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.

The “Airline/Manufacturer Maintenance Program Planning Document,” commonly known as MSG-3, is a method used (by the airlines and manufacturers) to develop the necessary maintenance/inspection program.
