FAA N-Number Lookup: How to Search the Aircraft Registry and Read What You Find

Purpose: What the FAA Aircraft Registry Is and What It Contains

The FAA Aircraft Registry is the federal government's official record of civil aircraft registered in the United States. It is kept by the FAA's Civil Aviation Registry, based in Oklahoma City, Oklahoma. The FAA's Aircraft Registry overview page describes what the registry does, including the public search tool.

An N-number is the registration mark assigned to a U.S.-registered civil aircraft. It always begins with the letter N, which is why people also call it a tail number. The registry ties each N-number to a set of facts:

• the aircraft's make, model and serial number
• the aircraft's category and class
• the registered owner's name and address
• the registration expiration date
• the airworthiness certificate status

Federal law makes registration the general rule. Under 49 U.S.C. § 44101, a person may operate an aircraft only when it is registered under section 44103 of that title. The statute lists three exceptions:

• operation authorized under section 40103(d) or 41703 of that title
• aircraft of the U.S. national defense forces that are identified in a way the FAA Administrator finds satisfactory
• a reasonable period after a transfer of ownership, under the Administrator's regulations

For someone affected by an accident, this rule is what makes the registry useful: because aircraft are generally required to be registered, the registry is often the first official record that names who held title. Title answers only one question, though. The registered owner is the person or entity holding the registration. The operator is the person or company that controlled and flew the aircraft. These can be the same, and they can be entirely different, a difference that comes up again and again in aviation cases.

If you are starting from a tail number, the registry record is a reasonable first document to gather and keep. It is a starting point for later questions, not an answer to who is responsible.

Step 1 — Find the N-Number Before You Search

The search field needs the aircraft's N-number, and families often find it in places they did not expect. Without it, the search is slower and less certain, so locating the number first can save time.

The N-number is usually displayed on the outside of the aircraft, often on the fuselage or tail. It also appears in:

• the aircraft's registration certificate
• news coverage and photographs
• air traffic control records
• FAA accident and incident data
• National Transportation Safety Board reports

The National Transportation Safety Board (NTSB) is the independent federal agency that investigates civil aviation accidents. Its preliminary and final reports identify each aircraft by its N-number. The NTSB describes the investigation; the FAA registry describes the aircraft's registration. The site's guide to the NTSB and the FAA explains how the two agencies divide their work.

If you have only part of a tail number, or only a description such as "a red single-engine plane," the registry's inquiry page offers other ways to search:

• by a partial N-number
• by manufacturer and model
• by serial number
• by owner name

A partial or descriptive search can return many records. Narrowing them down usually means comparing each result against what else is known, such as the aircraft type, the color, where it was based and the date of the event. No search method is certain to find a match.

Step 2 — Run the Search at registry.faa.gov

The search takes place on the FAA's Aircraft Inquiry page at registry.faa.gov. The database is public and free, and it needs no account or login. Anyone affected by an accident can see the same official record a lawyer or investigator would start from.

Some search fields expect the number without the leading "N." A tail number shown as N12345, for example, may need to be entered as 12345. If one format returns nothing, the other format is the usual next attempt.

A successful search returns a summary record that generally shows:

• the N-number and serial number
• the manufacturer and model
• the year of manufacture
• the type certificate information
• the registered owner and the owner's address
• the registration expiration date
• the airworthiness certificate class

For most aircraft, the record also links to a document index holding scanned copies of the registration history, including bills of sale, earlier registrations and airworthiness documents.

The online record reflects the documents the FAA has most recently processed, so it is not a same-day snapshot. If the accident was recent or the aircraft changed hands, the owner shown may not yet match the filings, and the date of the search is worth noting alongside a saved copy.

Methodology

The lookup on this page draws only on official federal sources. The registration data you see comes from the FAA Aircraft Registry, described on the FAA's Aircraft Registry page. That data exists because of the registration requirement in 49 U.S.C. § 44101, set out above with its exceptions. Investigation status and reports come from a separate agency, through the NTSB's investigations page, not through the registry. The tool presents what these sources show and adds no conclusions of its own.

For a reader, this means a result here carries the same weight as the FAA record it reflects, and no more. If you are also tracking the investigation, the NTSB page is a separate place to check.

Third-party aircraft registry tools

Privately run websites, such as aviationdb.com and airresearch.com, compile FAA registry data. Some present it in a more readable layout, and some may add flight-tracking history, accident flags or ownership timelines. These are not official government records. Naming them here is not an endorsement.

The authoritative source is always the FAA record at registry.faa.gov. A third-party result can differ from it, for example because of a timing gap or a data-entry difference. In that case, the FAA's own record and document index are the reference point for legal or investigative purposes. Someone comparing sources may find it useful to keep the FAA version as the copy of record.

Step 3 — Read the Registry Record One Field at a Time

Each field in a registry record answers a narrow question. Reading the fields one at a time keeps a record from seeming to say more than it does, which matters when the record may be the only official document a family has so far.

Who the Name in the Owner Field Actually Is

The registered owner is the legal titleholder on file with the FAA. It may be an individual, a corporation, a limited liability company (LLC), a partnership, a trust or a government entity.

What a Trust Name in the Owner Field Means

Trust ownership is common in aviation finance. When an aircraft is registered in a trust, the name shown is usually a trustee, who holds title on someone else's behalf. The person who benefits from the aircraft or operates it may not appear in the record at all. If you see a trust or LLC name, the open question is who stands behind it.

What the Expiration Date Does and Does Not Settle

The registration expiration date is the date the FAA has recorded for the registration to end. Renewal periods are set by FAA rules. The record shows the date, but by itself it does not settle whether a particular flight was authorized.

What the Airworthiness Certificate Line Tells You

The certificate class on the record, such as Standard or Special, tells you that the FAA issued a document reflecting that the aircraft met the standards for its type, along with related details. It does not tell you whether the aircraft was actually maintained or how it was flown on a given day.

Why the Kind of Aircraft Changes What Records Exist

The category and class field tells you what kind of aircraft was involved, such as fixed-wing, rotorcraft or glider. For you, that shapes which rules and which other records are likely to apply. An experimental aircraft record, for example, reads differently from a record for a certified airliner.

Document index

The document index shows the chain of ownership, through bills of sale and earlier registrations. Read in date order, it can show who held title on a particular past date, which the summary record alone does not. Someone trying to identify the owner on the day of the accident may want to download these documents and line them up by date.

Limitations: What the Registry Record Does Not Tell You — and Why That Gap Matters After an Accident

The registry shows the registered owner. It does not show the operator, the pilot, the maintenance provider or anyone who chartered the flight.

It also does not show the type of operation. Three FAA rule sets come up most often:

• Part 91 covers general operating rules, including most private flights.
• Part 135 covers charter and air taxi operators, which hold a separate FAA certificate.
• Part 121 covers airlines.

Which rule set applied to a flight is not in the registry. FAA operator certificate records are a separate database.

The registry does not show compliance with airworthiness directives. An airworthiness directive is an FAA safety order requiring an inspection or a fix. Compliance is recorded in the aircraft's maintenance records, which are not public. The site's page on aircraft maintenance negligence explains why those records matter.

The registry contains no accident history. NTSB investigation status, preliminary reports and final probable-cause reports come from the NTSB. A probable cause is the NTSB's official statement of why an accident happened. The NTSB's case file is described on the site's page about the NTSB docket. FAA accident and incident data and FAA hotline records are also kept apart from the registry.

Timing can change what the registry shows. If an aircraft was sold after the event, a search today may show the new owner rather than the owner at the time of the accident. The document index is where that timeline can be traced.

The lookup cannot fill these gaps and does not try to. Questions of who is at fault, what deadline applies and what a claim is worth sit outside it. For a family, this can be the hardest part: the name on the record may be the only name they have, yet it may not be the company that was actually flying the aircraft. A useful next step is often to list what the registry answered and what it left open, such as the operator, the rule set and the maintenance history, so those questions can be raised with whoever reviews the records.

When a Registry Search Is Part of Understanding an Aviation Accident

A registry search is one factual input among several. Knowing who held title, what the aircraft was and what certificate class it carried gives an injured person or a family a fixed point that the other records are built around.

The other questions sit beside it:

• Who operated the flight, and under which rule set?
• Who was the pilot?
• Who maintained the aircraft?
• Did a component fail, and who made it?

Whether any of these parties may be responsible depends on the facts and on the law that applies, and federal aviation rules and state injury law are separate layers. The site's page on aircraft product liability explains how those layers divide when a part is at issue.

State law matters too. Limitation periods, fault rules and damages rules differ from state to state, and the type of operation can affect them. No single deadline applies everywhere, and a registry record says nothing about which rule applies.

People who have gathered registry records, NTSB reports, photos and medical records often reach a point where the documents raise more questions than they answer. At that stage, a conversation with our attorney can cover what the records show and what remains open. If that would help, you may want to consider a case evaluation request.
