When can a pilot legally remove, install, or repair landing gear tires?

A pilot can legally remove, install, or repair landing gear tires on aircraft they own or operate due to regulations that permit pilots to perform certain maintenance tasks on their own aircraft without needing additional oversight. The Federal Aviation Administration (FAA) allows private pilots to conduct limited maintenance on aircraft they own, which includes basic tasks related to the routine upkeep of tires, provided they are familiar with the process and tools involved.

This understanding is grounded in the FAA's regulations that balance safety with the operational requirements and conveniences for aircraft owners and operators. By allowing pilots to engage in such maintenance tasks, it ensures that those directly familiar with the aircraft's condition are capable of addressing essential maintenance and ensuring safety.

The other options assume certain limitations or conditions that do not apply universally. For instance, removing, installing, or repairing tires strictly under supervision may not always be necessary for pilots working on their own aircraft, and performing these tasks on any aircraft (regardless of ownership) could have legal implications as maintenance responsibilities may differ based on ownership and regulatory guidelines.
