MRO & Sustainment Contractors

You're holding decades of technical CUI. Most of it unmanaged.

Depot maintenance firms, field service organizations, and parts suppliers keeping military platforms operational are sitting on maintenance records, technical manuals, and repair specifications for active systems, with no roadmap for what CMMC compliance actually requires of them.

Decades of accumulated maintenance history in systems that predate any compliance framework
Active platform technical manuals are CUI regardless of how long you've had them
Complex sustainment scope is harder to bound than production, and assessors know it

Maintenance data is CUI. All of it, going back years.

Technical manuals for active military platforms, maintenance records referencing operational platform configurations, and repair specifications for active systems are CUI, and the obligation to protect them does not come with an exemption for age or legacy format. If it is in your environment and it describes an active military platform, it is in scope. The MRO challenge is that this data was generated continuously over years or decades, lives in systems built before compliance was a consideration, and is distributed across technical libraries, maintenance management systems, project folders, and individual technician workstations.

Technical manuals (active platforms)

Aircraft maintenance manuals, structural repair manuals, and illustrated parts catalogs with Distribution C or D markings are CUI. Most are in daily use on the hangar floor with no formal access or disposal controls.

Maintenance records

Records referencing individual tail numbers, component replacement histories, and anomaly investigations describe operational military platform status. CUI from day one of creation.

Repair specifications and engineering orders

Depot-level repair specifications, time compliance technical orders, and engineering directives for active platform modifications are CUI regardless of how they were formatted or distributed.

Platform configuration data

Configuration management records that track installed components, modifications, and departures from baseline describe the operational capability of active assets, among the most sensitive CUI in the sustainment world.

Read: why sustainment scope is the most complex
Not sure if your MRO work creates a CMMC obligation?
The trigger is simple: if you hold technical manuals, maintenance records, or repair specifications for active military platforms under a DoD contract, you have CUI and you have obligations. Talk to us about what that means for your specific environment.

On-premises compliance for complex environments.

MRO environments cannot use cloud-hosted compliance platforms. The sensitivity of active platform data, maintenance records, technical manuals, and configuration data, means the compliance program must live inside your network alongside the data it governs. 1TEN deploys as an on-premises appliance with no external connectivity. All 110 requirements are covered with guidance specific to sustainment environments: maintenance system scope, technical library management, subcontractor access controls, and the legacy system compensating control documentation that assessors require.

Legacy system documentation

Compensating control frameworks for maintenance systems and test equipment that cannot be patched or upgraded, documented in a format assessors accept.

Technical library management

Access control and retention documentation for controlled technical publications, from distribution tracking to disposal procedures for superseded revisions.

Maintenance access controls

Visitor and maintenance access procedures for outside service technicians, subcontractors, and government representatives accessing your CUI environment.

SSP and SPRS output

Complete System Security Plan and SPRS score documentation, generated from your actual implementation, not adapted from templates that don't reflect your environment.
