What is Swiss-AS AMOS? Modules, integrations and alternatives
Swiss-AS AMOS is an aviation maintenance and engineering software suite from Swiss Aviation Software, used by airlines, MROs and operators to plan maintenance, track technical records and manage materials. It covers the airworthiness-driven processes that a general ERP does not: task cards, component tracking and regulatory records. It is typically run alongside a finance ERP rather than replacing it.
Also known as: AMOS, AMOS MRO, Aircraft Maintenance and Operations System, Swiss-AS
AMOS is a maintenance and engineering information system built around the aircraft as the central object. Users record flight hours and cycles, plan scheduled checks from the approved maintenance programme, raise defects, track airworthiness directives and service bulletins, and manage the installed component configuration of each tail number. The output is a technical record that supports release to service and regulatory audits.
Typical users are airlines, helicopter and business-jet operators, and Part 145 maintenance organisations, along with the continuing airworthiness and engineering teams that support them. Roles are sharply different from a factory ERP: planners, certifying staff, stores, engineering and quality each work in their own screens, and the approval trail matters as much as the data.
In a wider stack, AMOS usually owns maintenance, engineering and technical stores, while a corporate ERP owns general ledger, payables and procurement approvals. Interfaces move purchase requests, receipts, costs and sometimes payroll or time data between them. Flight operations, crew and fuel systems often feed utilisation data into AMOS.
Modules and capabilities
Maintenance planning and programme
Builds work packages from the approved maintenance programme based on hours, cycles and calendar limits.
Technical records
Maintains the aircraft and component history, configuration and compliance evidence.
Line and base maintenance execution
Task cards, defect handling, deferrals and sign-off for line stations and hangars.
Materials and stores
Inventory, repair orders, exchange and loan of rotable components, with traceability by part and serial.
Engineering
Handles airworthiness directives, service bulletins and modifications and links them to affected aircraft.
Quality and safety
Audit findings, occurrences and corrective action tracking.
Reliability and reporting
Defect trending, component removals and fleet performance reports.
Integrations and data access
Finance and procurement ERP
Usually interfaced to SAP, Oracle or similar for purchase orders, receipts and cost postings.
Flight operations
Utilisation, flight logs and delays are imported from operations or crew systems.
Manufacturer data
Maintenance data and technical publications from OEMs are loaded or linked, often following ATA iSpec 2200 conventions.
Parts supply
Exchange with suppliers via ATA Spec 2000 style messaging and portals where used.
Database access
Reporting and BI tools typically read from a reporting copy of the relational database.
Strengths
- Built specifically for airworthiness processes rather than adapted from plant maintenance
- Covers the planning, execution, stores and records chain in one data model
- Long history in airline and MRO use gives a mature feature set
- Aircraft and component configuration tracking supports audits and releases
Limitations
- Financial accounting is out of scope, so an ERP interface is required
- Heavy configuration and data migration effort during implementation
- User interface and mobile experience vary by version and should be assessed in a demo
- Customer-specific customisations can complicate upgrades
Where AI helps Swiss-AS AMOS users
- - Natural language search across task cards, defect histories and technical logs for troubleshooting precedent
- - Drafting defect rectification summaries and deferral justifications for human certifying staff to review
- - Extracting data from scanned vendor certificates and release documents for stores receiving
- - Answering planner questions about due items and component life status from read-only queries
- - Private, on-prem models so maintenance records and OEM manuals never leave the organisation
Evaluating Swiss-AS AMOS? Check these
- Map your regulatory scope first, such as Part 145, Part-CAMO or FAA Part 121, and confirm each is supported
- Ask for a data migration plan covering component history and life-limited parts
- Check how the finance ERP interface handles costs, repair orders and invoicing
- Test certifying-staff workflows and electronic signature handling
- Verify mobile and offline options for line stations
- Understand upgrade policy for customised installations

Frequently asked questions
What does AMOS stand for?
AMOS refers to the Aircraft Maintenance and Operations System, the product name used by Swiss Aviation Software. It is a maintenance and engineering suite for aircraft operators and maintenance organisations, not a general business ERP.
Is AMOS an ERP?
Not in the usual finance and supply chain sense. It manages aircraft maintenance, engineering, technical records and rotable materials. Most users pair it with a corporate ERP for accounting, general procurement and payroll, and connect the two through interfaces.
Who uses AMOS?
Airlines, other aircraft operators and maintenance, repair and overhaul organisations. Within them, planners, engineers, stores staff, certifying personnel and quality managers use different parts of the system according to their roles.
How does AMOS compare with other MRO systems?
Products such as Ramco Aviation, TRAX, IFS Maintenix and Rusada ENVISION cover similar ground. Differences lie in fleet focus, deployment model, user experience and integration approach, so run scripted demos with your own maintenance scenarios.
Can AI be added to AMOS safely?
Yes, if it starts read-only and keeps humans in release-to-service decisions. Retrieval over records and manuals, summarisation and document extraction are lower risk. Any write-back should require explicit approval and be logged, and regulators expect traceability.
Running Swiss-AS AMOS?
We add AI, chat, automation and integrations to the systems manufacturers already run, on-prem if needed.
