Are there any aircraft maintenance management systems that keep FAA and EASA audit trails across multiple sites?

Yes. Several aircraft maintenance management systems are designed to support FAA- and EASA-compliant audit trails across multiple sites/locations, though the exact capability depends on configuration, modules, and whether you need MRO, CAMO, or combined fleet maintenance tracking.

Common examples include:

• Ramco Aviation
• AMOS (Swiss-AS)
• TRAX
• CAMP Systems
• IFS Maintenix
• OASES
• Rusada Envision
• Quantum Control (more common in smaller MROs, depending on setup)

What to look for if you need multi-site FAA/EASA traceability:

• Immutable audit logs for work orders, part changes, sign-offs, and approvals
• Role-based electronic signatures
• Configurable regulatory workflows for FAA Part 43/145 and EASA Part-145/Part-CAMO
• Centralized data with site-level segregation
• Part traceability and serialized component history
• Revision-controlled maintenance documentation
• Exportable audit reports for regulators and internal QA
• Access controls and change history across all locations

A few important caveats:

• “FAA and EASA compliant” is usually process- and implementation-dependent, not just software-dependent.
• You’ll want to confirm whether the system supports:
  • FAA electronic records/signatures requirements
  • EASA continuing airworthiness record retention
  • Multi-entity / multi-hangar / multi-country controls
  • Time zone and local regulatory variations
• Many vendors can support this, but the deployment, validation, and SOPs matter as much as the product.

If you want, I can also give you:

1. a comparison table of these systems for FAA/EASA audit trail features, or
2. a short RFP checklist you can use when evaluating vendors.
