Mosaic is proud to support the development and release of the FAA’s Maintenance Management Information Exchange Model (FAA MMIXM) 4.0.0, a vital data standard that enhances the communication of operations and maintenance information across the National Airspace System (NAS). By enabling seamless data integration, MMIXM ensures that critical maintenance activities are accurately recorded, monitored, and shared among stakeholders.
Our analysts work closely with FAA and Volpe Center leadership to continuously refine and expand the model, ensuring it meets the needs of an evolving airspace. Maintenance data is highly complex, covering everything from sensor readings on critical equipment to system availability and the training and certification status of maintenance personnel. By providing a standardized framework, the FAA MMIXM allows disparate NAS systems to communicate effectively, reducing operational friction and increasing efficiency.
What is MMIXM?
The NAS depends on complex maintenance data, including:
- Sensor data measurements on equipment
- System availability tracking
- Training and certification status of maintenance personnel
- Logging of all maintenance activities affecting NAS equipment
- Performance data provided to Congress
MMIXM provides a common data standard, enabling seamless integration across NAS systems. By ensuring disparate systems “speak the same language,” FAA MMIXM supports both data producers and consumers, expanding its adoption across more programs.
What’s New in MMIXM 4.0.0?
With the release of MMIXM 4.0.0, the model has been expanded to include new capabilities that enhance its value for maintenance personnel and system operators. These updates were developed in collaboration with stakeholders representing the Remote Monitoring and Logging System (RMLS) National Logging Network (NLN) and the Facility, Service, and Equipment Profile (FSEP). The latest version enables better documentation of technician activities across the NAS, providing a more complete picture of maintenance efforts and system performance.
The Role of RMLS in NAS Maintenance
MMIXM 4.0.0 further supports the Remote Monitoring and Logging System (RMLS), which provides nationally supported Technical Operations maintenance monitoring and logging tools.
Key Capabilities of RMLS:
- Enables Tech Ops personnel to remotely monitor and control most NAS equipment outside the TRACON and ARTCCs
- Proactive response to operational challenges, such as starting engine generators in advance of storm-related power outages
- Centralized logging of all maintenance activities affecting NAS equipment
- Supplies NAS facilities performance data to Congress
Program Benefits:
- Centralized coordination of all NAS maintenance activities through OCCs and SOCs
- Real-time monitoring and control of key equipment nationwide
- Data integration with other NAS programs, feeding both Logging and Remote Maintenance Monitoring (RMM) data
- SWIM-compliant and capable of receiving Data Communications monitoring data

As MMIXM adoption continues to expand, Mosaic remains committed to supporting its development and integration. Our expertise in aviation data and operational efficiency helps drive innovations that improve maintenance coordination, reduce downtime, and enhance safety. Mosaic is excited to contribute to the ongoing evolution of aviation maintenance technology, ensuring the National Airspace System remains reliable, efficient, and ready for the future.
