MSG-3: A4A Maintenance Steering Group


 

Commercial Aircraft manufacturers and operators are required to develop their Scheduled Maintenance program (Maintenance tasks, intervals) according to the A4A MSG-3 analysis procedures, for certification purposes.

Created by the Maintenance Steering Group (MSG) of the Airlines for America (A4A – previously ATA – Air Transport Association), MSG-3 analysis is a method of developing maintenance/inspection tasks for aircraft and power plants.

The apmOptimizer MSG-3 Module enables Commercial and Military Aviation Maintenance Departments to efficiently implement the MSG-3/S4000M methodologies for scheduled maintenance tasks and intervals.

The apmOptimizer MSG-3’s decision-making logic is applied to each Maintenance Significant Item (MSI), categorizing its failure as a safety, operational and/or economic failure. Each category follows its own route in the logic flow and leads to the definition of a specific preventive or inspection maintenance scheduling.

The MSG-3 Module is compliant with relevant ATA Standards Spec 2000 Chap 11. Using the apmOptimizer optimization algorithms, the MSG-3 tasks and intervals can be combined with Operators or OEM in-service data in order to perform optimization (escalation, de-escalation, adding or removal) of these tasks, for minimizing maintenance costs and optimizing aircraft reliability and availability metrics (Spec 2000 Chap. 13 future compliance).

Moreover, apmOptimizer’s capabilities enable customers to optimize their maintenance strategy at the asset level by optimizing repair level, inventory levels and locations, resources allocation, for additional lifecycle cost reduction.
