AAR Corp

AAR CORP. (NYSE: AIR) is a global aerospace and defense aftermarket solutions company and the number one aviation maintenance, repair and overhaul (MRO) provider in North America. It supplies new and used airframe and engine parts, performs airframe and component MRO, runs expeditionary and sustainment programs for government and defense customers on five continents, and operates four aviation software businesses — Trax (eMRO/eMobility aviation ERP), Aerostrat (Aerros maintenance scheduling), Airvoyant (AI-driven parts procurement, launched April 2026) and Airinmar (component repair and warranty management) — whose software covers more than 10,000 aircraft.

scored 2026-09-10 · rubric v0.20.0
Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/aar: open an issue to ask a question, or submit a pull request to add artifacts.
