MSG-3 Maintenance Steering Group

Maintenance Steering Group-3 (MSG-3) is a method for developing preventive maintenance programs in the aerospace industry. The process is maintained by A4A (Airlines For America formerly known as ATA).

MSG-3 is a structured process for identifying Safety Significant Items (SSI), defining for each SSI the failure modes and effects (FMEA). A decision tree is then applied to decide the maintenance strategy for each SSI.

Leading aircraft manufacturers use BQR’s MSG-3 software.
