Croatia 🇭🇷 CCAA Registry

Name	hr-ccaa-registry
Country	Croatia
Registration prefix	9A-
Data source	https://www.ccaa.hr/en/list-of-registered-aircraft-94674
Format	PDF (URL discovered by scraping the index page for the first /file/ link)
Run frequency	Weekly (Tuesday, 23:10 UTC)
Depends on Mictronics for ICAO hex	Yes — this runner does not publish ICAO hex addresses; registrations are resolved via RediSearch against Mictronics records (idx:aircraft:mictronics). Must run after the mictronics runner.

How it works

The Croatia CCAA index page is scraped for the first anchor tag whose href contains /file/, which is followed to download the current register PDF. Each page is parsed with pdfplumber's built-in table extraction (extract_table()), which works reliably on this PDF. Rows are matched against a strict suffix pattern (^[A-Z0-9]{2,4}$) before the 9A- prefix is prepended, filtering out header/footer noise rows that don't contain a real registration suffix. Every written record explicitly sets military: false — this register is exclusively civil, and the explicit value ensures a stale military: true flag (from Mictronics or a prior record on a reused hex) is corrected on re-registration.

Columns

Source column	Imported	Notes
REG. OZNAKA	✅	Suffix only (e.g. ABC); 9A- prefix prepended → used as the Mictronics lookup key
REDNI BROJ	❌	Parsed but not stored (row-number column)
PROIZVOĐAČ	✅	→ aircraft.manufacturer
OZNAKA ZRAKOPLOVA	✅	→ aircraft.model
SERIJSKI BROJ	✅	→ aircraft.serial_number
VLASNIK	✅	→ registrant.names[0]
ADRESA	✅	→ registrant.street (split on commas into parts)

See specs/data-dictionary.yaml (hr-ccaa-registry entry) for full column semantics and cross-source schema notes.

Example Output

Read back the merged record for a given ICAO hex (combines this runner's data with Mictronics and any other sources that have written to the same key):

Configuration

See Data Runners for the full list of environment variables every runner reads. This runner writes aircraft:registry:{icao_hex} with a fixed 14-day TTL (ENRICHMENT_TTL_SECONDS in shared/timing.py).

MQTT

Published once, at the end of a run, to SkyFollower/runner/hr-ccaa-registry/statistic/{name} (all retained):

Topic suffix	Value	Format
records_imported	e.g. 271	Integer as string
last_run_at	e.g. 2026-07-07T14:32:01.123456+00:00	ISO 8601 UTC
last_run_status	Success or Failure	String

Home Assistant autodiscovery configs are also published (retained) to homeassistant/sensor/SkyFollower_runner_hr_ccaa_registry_{name}/config for each of the three stats above.
