The removal, installation, and repair of landing gear tires by a private pilot on an aircraft they own or operate is considered?

The removal, installation, and repair of landing gear tires by a private pilot on an aircraft they own or operate is classified as preventive maintenance. Preventive maintenance refers to simple or minor preservation operations and the replacement of small standard parts that are not complex and do not require the use of specialized tools or techniques.

In the context of aircraft, preventive maintenance efforts are aimed at ensuring the aircraft remains in a safe and airworthy condition, which includes tasks that a private pilot is allowed to perform without needing a specific maintenance rating or authorization from the FAA, as long as the pilot is the owner or operates the aircraft. This classification simplifies the maintenance process for private pilots, as they can perform minor tasks that contribute to safety without extensive oversight.

In contrast, major repairs typically require certification or the involvement of licensed mechanics, and restricted activities often pertain to actions that individuals may not legally perform due to licensing requirements. Non-invasive maintenance is not a well-defined term in aviation maintenance regulations, making it less applicable to the question.
