New registry: Switzerland (FOCA) #switzerland-foca-registry

Aero Reg now covers a fourth national aircraft register: Switzerland’s Federal Office of Civil Aviation (FOCA / BAZL), including Liechtenstein-registered aircraft. Like FAA, CCAR, and CASA, this is a full daily-refreshed registry — not a monthly snapshot — with over 3,100 currently registered HB- aircraft and a deregistration archive reaching back to 1926.

added
  • Aircraft detail pages for Swiss (HB-) registrations, including engine, propeller, noise, and certification data not published by any other registry we cover.
  • Native ICAO24 (Mode S) transponder hex direct from the source register — no enrichment needed.
  • Full daily change feed: additions, modifications, deletions, re-registrations, and owner changes.
  • A deregistration archive of over 13,600 historical HB- registrations dating back to 1926, searchable alongside current aircraft.
  • Fleet browser, watch lists, and email alerts for FOCA aircraft, on the same terms as FAA, CCAR, and CASA.
  • REST API and CSV export support for FOCA snapshot and change-feed data.
  • Search and lookup support for HB- registrations and Swiss transponder hex codes across the site.
changed
  • Registry coverage framing across the site now lists four daily-updated registries: FAA, CCAR, CASA, and FOCA.

FOCA data is included in every paid plan’s country allowance, the same as FAA, CCAR, and CASA.

Market intelligence for Enterprise: US aircraft market trends, turnover, and the FAA backlog index #market-intelligence

Enterprise members now get a market-intelligence layer built on the FAA document recordation stream: monthly transaction trends, financing and refinance activity, fleet-deal detection, distress filings, model turnover leaderboards, export destinations, and a first-of-its-kind FAA processing-backlog index — all available on a new dashboard page and through the API.

added
  • A Market intelligence page (Enterprise) with monthly aircraft-sales trends split by segment (piston, turboprop, jet, electric), financing penetration and refinance counts, repossession and court-filing trends, a model turnover leaderboard, top manufacturers and states, and export destinations.
  • The FAA processing-backlog index: the median lag between a bill of sale being recorded and the ownership change appearing in the FAA master registry, tracked month by month. The backlog has risen from about four weeks to over ten weeks since late 2025 — Enterprise members can watch it move.
  • Four new API endpoints under /api/v1/market/ — summary, series, breakdown, and turnover — with JSON and CSV output, gated by the new market:read scope. New API keys include the scope by default; existing keys need it added.
  • Quick-resale tracking: the share of recorded sales where the same aircraft sells again within 6 or 12 months.

Series begin May 2025 (document history reaches back to April 2024). Metrics are derived from recorded-document activity; this is not a title search, and no claim of clear title is made.

Public API reference #api-reference

A public, browsable API reference is now live. Every endpoint is documented with its parameters and response shapes, generated at build time so the docs never drift from the code.

added
  • The /api-reference page, with per-endpoint request and response samples.
