ATA Spec 2000 — aviation e-business
Spec 2000 is the e-business standard of the aviation industry, published by the ATA (Air Transport Association, now A4A). It governs exchanges between airlines, manufacturers (OEMs), suppliers and maintenance shops (MRO): spare parts, repairs, reliability data.
What is Spec 2000?
A fleet only flies if the right part, with the right documentary pedigree, reaches the right hangar. Spec 2000 standardises this very particular trade: catalogues and initial provisioning for a new aircraft, parts ordering, quotes and repair orders, and reliability data exchange between operators and manufacturers. It is one of the oldest sector EDI ecosystems — and one of the most critical, because traceability there is an airworthiness requirement, not a nicety.
The chapters: one standard per process
| Domain | What Spec 2000 covers |
|---|---|
| Provisioning | Initial parts data for an aircraft's entry into service |
| Materiel | Spare-parts orders, quotes, status and invoices |
| Repair | Repair orders and their tracking at MROs |
| Reliability | Removal and performance data fed back to the OEMs |
| Traceability | Part identification and history (up to RFID, a dedicated chapter) |
The aviation specifics
- The documentary pedigree — a part without its certificate (8130-3 / EASA Form 1) is unusable: the flows carry compliance as much as logistics.
- Repair as a central flow — you do not scrap a $500k component: the repair order (send, quote, overhaul, return) is as structural as the purchase order.
- AOG (Aircraft On Ground) — the ultimate emergency order, with its accelerated circuits.
- Early serialisation — part number + serial number + whole-life traceability, long before other sectors got there.
Spec 2000 in the sector landscape
- vs VDA / Odette: the same logic of a vertical standard born from an industry's constraints — automotive for them, airworthiness here.
- vs EDIFACT/X12: airlines also use the horizontal standards for non-aviation supplies; Spec 2000 rules parts and maintenance.
- Access: unlike most standards on this site, Spec 2000 is distributed under licence by A4A.
