What Happens When an Aircraft Is Deregistered?
February 2, 2026
Deregistration Defined
When an aircraft is deregistered, it is removed from the FAA Civil Aviation Registry active rolls. The aircraft loses its valid U.S. registration certificate, which means it cannot legally operate in U.S. airspace until a new, valid registration is in place. Deregistration does not necessarily mean the aircraft is destroyed or permanently grounded — it can have many causes.
Common Causes of Deregistration
The most frequent reason for deregistration is export. When a U.S.-registered aircraft is sold to a buyer in another country, the FAA registration must be cancelled before the aircraft can be registered under the new country registry. This is a normal and healthy transaction — aircraft frequently move between countries throughout their service lives.
Other common causes include:
- Registration expiration — If an owner fails to renew the triennial registration, the FAA will administratively cancel it.
- Total loss — Aircraft destroyed in accidents, fires, or floods are deregistered once the owner reports the loss.
- Scrapping — Aircraft retired from service and parted out or scrapped are supposed to be deregistered, though compliance is imperfect.
- Voluntary cancellation — Owners occasionally cancel registrations for legal restructuring purposes.
The Deregistration Process
The FAA Aircraft Registration Branch in Oklahoma City handles deregistration paperwork. An owner submits a cancellation request, and the FAA issues a Certificate of Export Airworthiness for exported aircraft or simply cancels the registration. The aircraft record moves from the active registry to a historical archive.
What Happens to the N-Number?
A deregistered N-number enters a mandatory waiting period before it can be reassigned to a different aircraft. This prevents confusion in historical records and in air traffic control systems. High-profile N-numbers associated with notable aircraft are sometimes retired permanently.
Finding Deregistered Aircraft
You can browse recently deregistered aircraft on this site. The historical records are still publicly available and can be valuable for researchers, historians, and buyers doing due diligence on an aircraft past. A clean deregistration history — especially one showing a straightforward export — is very different from a registration cancelled for cause. When searching any aircraft, check the full registration history before drawing conclusions.
