How the FAA Registry Is Updated and How Often the Data Changes
March 16, 2026
The FAA Data Release Schedule
The FAA Civil Aviation Registry is a live database that the FAA updates continuously as registration applications, renewals, and cancellations are processed. However, the FAA does not provide real-time public access to the live database. Instead, it releases the full registry dataset as a bulk download that is updated on a scheduled basis — typically nightly on weekdays.
This means that if an aircraft was registered or deregistered yesterday, it may not appear in public-facing registry tools (including this site) until the next data release is processed.
What Triggers a Registry Update?
The registry changes whenever the FAA Aircraft Registration Branch in Oklahoma City processes paperwork. Common triggers include:
- New aircraft registrations (new aircraft purchased from a manufacturer)
- Change of ownership (aircraft sold)
- Address changes by existing registrants
- Registration renewals
- Registration cancellations and deregistrations
- Administrative status changes such as expiration and FAA-initiated cancellations
Processing Delays
The FAA processes paper and electronic submissions, and there can be delays between when a transaction actually occurs (a plane is sold, an owner dies, a company dissolves) and when the registry reflects the new reality. Real estate transactions often close faster than FAA registration updates, which means the registry sometimes lags behind the actual legal state of aircraft ownership by days or weeks.
How This Site Processes the Data
This site ingests the FAA bulk data release and processes it to populate the searchable database you use when you look up a tail number or browse by state. The data sources page provides specific information about when the data was last updated and from which FAA release it was drawn.
Implications for Research
When conducting time-sensitive research — such as verifying aircraft ownership for a pending transaction — always check the data freshness and consider whether the registry data might lag behind recent events. For historical research or fleet analysis, the regular update cadence is more than sufficient, and the FAA archive of previous releases enables longitudinal analysis of how the registry has changed over time.
The FAA also releases supplemental datasets including deregistered aircraft records, which follow a similar update schedule and are incorporated into this site data.
