# TailLookup

> Public aircraft history records for US-registered aircraft, compiled from
> public FAA registration and NTSB accident data. One page per tail number.

## What this is
TailLookup publishes a free, citable history report for each US aircraft tail
number (N-number): its airframe (make, model, year, serial), current
registration and owner, a registration timeline built from daily snapshots, and
every NTSB accident record on file — with probable causes. Every fact traces to
a government source and a snapshot date.

## URL patterns
- https://taillookup.com/n/{TAIL} — the history report for one tail number.
  Examples: https://taillookup.com/n/N1258C , https://taillookup.com/n/N1544

  (e.g. https://taillookup.com/make/cessna/172).
- https://taillookup.com/owner/{owner} — an owner/operator's registered fleet
  (e.g. https://taillookup.com/owner/delta-air-lines-inc).

  NTSB accident records per 100 airframes, by model.
- https://taillookup.com/guides/{slug} — factual guides on aircraft records
  (e.g. https://taillookup.com/guides/check-aircraft-accident-history).

## Coverage
- 314,477 aircraft currently on the FAA register (every N-number has a page).
- 24,491 of those tails have one or more NTSB accident records (prioritized in the sitemap).

## API & MCP

## Accuracy
Records are compiled verbatim from government files; we do not fabricate,
interpolate, or infer. Each page carries an "as of" snapshot date.

## How to cite
