Which of the following aircraft are not subject to the registration provisions?

The correct answer points to the fact that certain aircraft are exempt from the standard registration requirements typically applied in civilian aviation. Specifically, aircraft owned by the United States government are not subject to these provisions since they fall under a different category of aircraft operations and management maintained by federal entities.

Additionally, the question specifies types of aircraft associated with specific residency or ownership criteria. Aircraft owned by non-residents or based in other states do not qualify for standard registration if they meet specific criteria as defined in aviation regulations. This underscores the notion that not all aircraft fall under the same registration laws, particularly those related to governmental ownership or specific state residency.

Since the answer includes all scenarios provided—government ownership and those associated with state residency—the comprehensive nature of the correct option captures the correct regulatory framework. Thus, all listed aircraft types indeed are exempt from the registration provisions, reinforcing the concept that certain aircraft ownership does not impose registration requirements under aviation regulations.
