Definition
A section of the U.S. federal aviation regulations that specifies the conditions under which a Certificate of Aircraft Registration expires, including events such as the aircraft being sold or transferred, exported, destroyed, scrapped, or when the registered owner loses U.S. citizenship status. It also addresses the duration limits of registration and what triggers the need for re-registration or cancellation.
Plain English
This is the federal rule that lists the things that cause an aircraft's registration certificate to no longer be valid -- like selling the aircraft, scrapping it, or losing citizenship eligibility.
Context Anchor
Seen when studying aircraft registration requirements, especially the rules for how long a Certificate of Aircraft Registration lasts and what can make it end.
Derivation
CFR stands for Code of Federal Regulations. 'Part 47' is the chapter dealing with aircraft registration, and 'section 47.41' is a specific numbered rule within that chapter. The numbering system works like an address: Title 14 (Aeronautics and Space) → Part 47 (Aircraft Registration) → Section 41 (the specific rule on when registration ends).
Why Pilots Care
An invalid registration makes the aircraft unairworthy for legal flight and can result in FAA enforcement action against the owner or pilot.
Intuition Check
Do not read this as just a page number or a casual reference. It is a legal citation: Title 14 of the Code of Federal Regulations, Part 47, Section 47.41.
Example Sentence 1

Example Sentence 2
