TransDigm Group
TransDigm Group is a leading global designer, producer, and supplier of highly engineered aerospace components, systems, and subsystems for use on nearly all commercial and military aircraft. The company operates 49 independent operating units producing proprietary, sole-source components including actuation systems, ignition systems, fuel systems, airframe and flight control components, cockpit security systems, seatbelts, airbags, pumps, valves, switches, and cockpit displays. TransDigm serves commercial airlines, defense OEMs, aerospace distributors, and the US Department of Defense.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles TransDigm Group the way a machine reads it — 19 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — TransDigm Group scores 24.8/100 (emerging), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

Semantic Vocabularies 1
JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.
