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.
BQR’s apmOptimizer software helps to organize the MSG-3 tasks and reports.
Steps for conducting MSG-3 analysis
- Import the block tree, components and failure modes from BQR’s FMECA using BQR’s Core Database
- Alternately, data can be imported from CSV files
- For each item, follow the decision trees according to MSG-3 forms
- The software validates the user data. If data is missing, user is notified
- Detailed reports for all MSG-3 forms
- Libraries for functions, malfunctions, explanations and more
- Import tree from Excel or BQR CARE
- Notify user if project data is incomplete or inconsistent
- Detailed help and wizard for beginners and advanced users
