Experimental is a certification category, not a description of the paperwork. 43,038 currently-registered US aircraft carry an experimental certification code — amateur-built, exhibition, and kit aircraft among them — and every one of them is on the same public FAA registry, with the same registration history, filed documents, and accident record as a factory-certified airplane.
Run the same records check
- Registration status and ownership history — identical process to any other aircraft.
- Accident and incident history — matched by serial number as well as tail number. Amateur-built aircraft are reassigned N-numbers just like factory aircraft, so the same reassignment trap applies.
- Filed documents — bills of sale and liens, same federal filing system.
The extra record worth pulling: the builder
Kit and amateur-built aircraft carry something factory aircraft do not: FAA's registration file separately records a kit manufacturer and kit model for a real share of them — 17,000 of the aircraft in the current registry, checked directly against the data. That field exists because who built the airplane, and to what standard, matters more on an experimental than almost anywhere else. There is no type-certificated production line holding every unit to an identical standard; quality genuinely varies builder to builder.
Before you buy, confirm:
- The kit manufacturer and model on the registration match what you are being told about the airplane.
- The builder's own records — the airworthiness inspection the FAA or a designated inspector performed before it was first certificated, plus subsequent condition inspection logs — are available and complete. An experimental aircraft is not covered by a manufacturer's type certificate, so this paperwork is the closest thing it has to one.
- Whether you are the original builder-owner or a subsequent buyer. Under FAA rules, only the original builder can perform the aircraft's annual condition inspection unless a repairman certificate has been issued to someone else — a detail that affects your ongoing maintenance options, not just its history.
What stays the same
Serial number over tail number for accident matching, records before inspection, and a pre-buy from someone who knows the specific type — all the same discipline that applies to a certificated aircraft applies here too. The only difference is one extra document to ask for: proof of who built it and how.
