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.

New registries: Moldova, Sri Lanka, Papua New Guinea, Luxembourg, and Norway #moldova-srilanka-png-luxembourg-norway-registries

Five more national aircraft registers join Aero Reg in our biggest single expansion yet: Moldova (CAA Moldova), Sri Lanka (CAASL), Papua New Guinea (CASA PNG), Luxembourg (DAC), and Norway (Luftfartstilsynet). That brings snapshot-based registry coverage to thirteen countries, searchable alongside the FAA, Transport Canada, and CASA Australia registers.

added
  • Aircraft detail pages for Moldovan (ER-), Sri Lankan (4R-), Papua New Guinean (P2-), Luxembourgish (LX-), and Norwegian (LN-) registrations, including manufacturer, model, and serial number where published.
  • Norway is our first register sourced from a structured national open-data feed — refreshed daily by the Norwegian CAA — and includes registration dates, airworthiness categories, co-ownership details, and authoritative Mode S transponder codes straight from the register.
  • Richer per-registry detail where the source publishes it: operator names and addresses (Papua New Guinea, Sri Lanka), separate owner and operator parties (Luxembourg, Norway), aircraft categories and maximum take-off weight (Norway).
  • Search support: look up any of these marks from any public search box, or find one by its Mode S hex code where a transponder assignment is known.
  • Mode S hex enrichment from our curated transponder database across all five fleets.
  • The coverage page now lists all five as live registries with current aircraft counts.

As with all our snapshot registries, this data is available on every plan, including free accounts, and does not count against country allowances.

New registries: Spain, the Maldives, and Malta #spain-maldives-malta-registries

Three more national aircraft registers join Aero Reg: Spain (AESA), the Maldives (Maldives CAA), and Malta (Civil Aviation Directorate). All are monthly snapshots — around 5,570 Spanish, 138 Maldivian, and 948 Maltese aircraft — searchable alongside every other registry we cover. Spain is our largest snapshot-based register to date.

added
  • Aircraft detail pages for Spanish (EC-), Maldivian (8Q-), and Maltese (9H-) registrations, including manufacturer, model, and serial number.
  • Aircraft category/classification for Spanish and Maltese aircraft (aeroplane, helicopter, microlight, and more).
  • Richer per-registry detail where the source publishes it: owner/operator names and addresses (Maldives, Malta), maximum take-off weight (Malta), registration dates and engine details (Spain), and airworthiness and mortgage/IDERA status (Maldives).
  • Search support: look up any of these marks from any public search box, or find one by its Mode S hex code where a transponder assignment is known.
  • Mode S hex enrichment from our curated transponder database across all three fleets.
  • The coverage page now lists all three as live registries with current aircraft counts.

Spain, Maldives, and Malta data is available on every plan, including free accounts, and does not count against country allowances.

New registries: the Cayman Islands, Cyprus, and Hungary #cayman-cyprus-hungary-registries

Three more national aircraft registers join Aero Reg: the Cayman Islands (CAA Cayman), Cyprus (DCA), and Hungary (Transport Authority). All are monthly snapshots — around 211 Cayman, 140 Cypriot, and 1,234 Hungarian aircraft — searchable alongside every other registry we cover.

added
  • Aircraft detail pages for Cayman (VP-C and VQ-C), Cypriot (5B-), and Hungarian (HA-) registrations, including owner/operator, manufacturer, model, and serial number.
  • Richer per-registry detail where the source publishes it: registered addresses and registration dates (Cayman, Hungary), owner nationality (Cayman), separate manufacturer/model and maximum take-off weight (Cyprus), and airworthiness-review dates (Hungary).
  • Search support: look up any of these marks from any public search box, or find one by its Mode S hex code where a transponder assignment is known.
  • Mode S hex enrichment from our curated transponder database across all three fleets.
  • The coverage page now lists all three as live registries with current aircraft counts.

Cayman, Cyprus, and Hungary data is available on every plan, including free accounts, and does not count against country allowances.

New registries: Austria and the Bahamas #austria-bahamas-registries

Aero Reg now covers two more national aircraft registers: Austria (Austro Control) and the Bahamas (CAAB). Both are monthly snapshots — around 1,875 Austrian and 140 Bahamian aircraft — searchable alongside the FAA, CCAR, and CASA registries.

added
  • Aircraft detail pages for Austrian (OE-) and Bahamian (C6-) registrations, including owner/operator, manufacturer, model, and serial number.
  • Search support: look up an OE- or C6- mark from any public search box, or find one by its Mode S hex code where a transponder assignment is known.
  • Mode S hex enrichment from our curated transponder database — most Austrian aircraft and the majority of the Bahamian fleet resolve by hex.
  • The coverage page now lists Austria and the Bahamas as live registries with current aircraft counts.
changed
  • Registry coverage framing across the site now distinguishes daily-updated registries (FAA, CCAR, CASA) from monthly snapshots (Austria, Bahamas).

Austria and Bahamas data is available on every plan, including free accounts, and does not count against country allowances.

Search from any public page - no JavaScript required #public-search-no-js

Aircraft search now works across the whole public site, with or without JavaScript. The homepage search boxes submit to a real lookup endpoint, results link straight through to the aircraft detail page, and public aircraft pages carry their own search bar with live suggestions.

added
  • A public lookup endpoint: searching a hex code or registration takes you directly to the matching aircraft page, even with JavaScript disabled.
  • A search bar on public aircraft pages - including the not-found page - with live hex and registration suggestions.
changed
  • Homepage search result cards now link to the full aircraft detail page; the whole card header is clickable.

Homepage lookup now covers Canadian and Australian aircraft #multi-registry-homepage-lookup

The free aircraft lookup on the homepage now searches all three live registries — the US FAA register, the Canadian Civil Aircraft Register (CCAR), and the Australian CASA register — instead of US aircraft only.

changed
  • Homepage lookup is now multi-registry: enter a transponder hex code or a registration from any live registry (for example N894QS, C-FAAA, or VH-22A) and the lookup resolves it to the right register automatically. Pre-1957 Canadian vintage marks (such as CF-JCA) are recognised too.
  • Result cards show the source registry: each result is badged with the registry it came from (FAA, CCAR, or CASA) alongside its status.

Public FAA dealer directory with free listing claims #dealer-directory

Aero Reg now includes a public directory of FAA-certificated aircraft dealers — around 1,500 active certificate holders, browsable by state and city, each with live certificate details and the aircraft currently registered to them. Individual-held certificates are shown to city precision only.

added
  • Dealer directory at /dealers: browse active FAA-certificated aircraft dealers by state and city, with certificate status, expiry dates, and fleet sizes, plus a most-active ranking from the last 90 days of registry activity.
  • Dealer profiles with the dealer’s current fleet matched daily against FAA registrations. Anyone can see the first aircraft; a free account unlocks the full fleet list on every profile.
  • Dealer badge on aircraft lookup: aircraft registered to an FAA-certificated dealer now show a badge linking to that dealer’s directory profile.
  • Free listing claims: certificate holders can claim their listing and, once approved, add a website, phone number, and description — shown as a verified claimed listing.
fixed
  • The XML sitemap is now generated and served correctly (a long-standing generation failure meant no sitemap had been published); it now includes the dealer directory pages.

Redesigned 404 and 500 pages #new-error-pages

The 404 and 500 pages have been rebuilt on the v2 design system and now share the public site chrome. The 404 is registry-aware: a missing aircraft URL gets a tail-number-specific message, everything else gets a generic one.

added
  • A registry-aware 404 that recognises aircraft lookups (/aircraft/, /h/, /r/) and tailors its message.
  • An honest request-diagnostics card showing the real method, path, referrer and timestamp.
changed
  • Both error pages now load the same aeroreg-core and aeroreg-public stylesheets and reuse the shared header and footer.
removed
  • The legacy hexdatabase 500 mascot and the WordPress-era 410 handling.
security
  • Reflected request data (path and referrer) is escaped on output; no fabricated request or incident IDs.
