**APIs profiled:** 3

The Civil Aviation Safety Authority (CASA) is Australia's independent statutory aviation safety regulator, established under the Civil Aviation Act 1988. It maintains the Australian Civil Aircraft Register (VH- marks), issues Airworthiness Directives, licenses flight crew and maintenance organisations, certifies air operators, and regulates drone and RPAS operations. CASA sits entirely OUTSIDE the travel distribution chain — it is a safety regulator, not a distributor, so it has no GDS, NDC, channel-manager or OTA position, and airline fare distribution, full-content agreements and consumer disclosure are not CASA functions. Its API posture is split and honest: two genuinely open, no-key, documented bulk data products (the full Airworthiness Directives listing as JSON/CSV and the complete civil aircraft register as a daily CSV, both served from services.casa.gov.au), and one approval-gated partner API — the CASA RPAS Digital Platform at data.casa.rpasplatform.net — whose endpoints are named in public PDFs but require a service account, a signed four-year agreement, a CASA onboarding check-out and a paid Airservices Australia airspace data licence. There is no self-serve developer portal, no OpenAPI, and new RPAS Platform onboarding is currently paused pending Airservices' Flight Information Management System.
