Methodology & sources

The two sources

Everything on this site and in every report comes from two cited public sources:

FAA Releasable Aircraft Database (Aircraft Registration Branch, Oklahoma City) — The official US civil aircraft registry. Registrations, deregistrations (ownership history), model/engine reference, and recent document filings. Refreshed daily by the FAA. We hold 314,372 current registrations plus the deregistered records and a model reference table.
NTSB Aviation Accident Database — US civil aviation accidents and selected incidents, 1962 to present, matched to an aircraft by registration number and serial number.

Vintages and refresh

The FAA refreshes the releasable registry daily; the NTSB updates its database on its own cadence. Current data vintages: FAA 2026-06-27, NTSB 2026-06-27 (last ingested 2026-06-27). Both stamps appear on every page and report. Anything decision-critical should be confirmed against the official FAA record.

The serial-number match

Aircraft change tail numbers. A hull sold and re-registered gets a new N-number, but its serial number stays with the airframe. So a report matches NTSB events to an aircraft two ways: by tail number, and by manufacturer serial number — so a past accident under a previous registration still surfaces. Serial matches are labeled as such, and only shown when the manufacturer agrees; they are not a guarantee that two records are the same airframe, only a strong signal worth checking.

What's included — and excluded

Missing values render as "not reported", never as zero — the FAA and NTSB report different fields.
The instant report covers the FAA Releasable database and loaded NTSB records. It is not a title search or lien abstract — recorded liens live in the certified FAA records file, which the Full tier orders separately.
The absence of an NTSB record is not proof of no damage history: only events reported to the NTSB within the loaded window appear, and minor incidents are often never reported.
This is not an airworthiness determination and does not replace a pre-purchase inspection.

Privacy posture

Public SEO pages on this site — model pages and state pages — show aggregate counts only. We never publish an individual owner's name on a browseable page. Individual registrant names appear only inside a paid, per-tail-number report that someone deliberately pulled for one aircraft, drawn directly from the FAA's own releasable registry.

Accident-rate framing

Where a model page shows an accident figure, it is always a rate: NTSB-recorded events in the loaded window among aircraft currently registered as that model, per 1,000 currently registered, across all severities. It is not a safety ranking and must not be read as "most" or "least dangerous" — fleet age, hours flown, mission, and reporting completeness all affect the number. The exact methodology sentence is printed verbatim on each model page.

This is an informational report compiled from public FAA and NTSB records. It is not a title search, lien abstract, or airworthiness determination, and does not replace a pre-purchase inspection. Liens and encumbrances require the certified FAA records — not included in the instant report.

Corrections

Every fact is attributed to the FAA or NTSB record it came from, with its vintage. If something is wrong, reply to any email from us — a human reads it, and we correct or remove promptly.
