What must be done regarding maintenance while changing landing gear tires?

When changing landing gear tires, partial jacking of the aircraft is necessary to ensure that the weight is adequately relieved from the tires being changed. This allows safe access to the tires and enables the maintenance personnel to perform the task effectively without risking damage to the aircraft or injury to themselves.

Partial jacking ensures that the aircraft remains stable, allowing the maintenance team to work safely while also not lifting the aircraft fully off the ground—this is particularly relevant when only tires are being changed. It is done to maintain control and stability of the aircraft during the maintenance process.

Other options such as completing the full jacking of the aircraft are not required for simply changing tires, as it increases the complexity and safety risks. Changing tires without any jacking is not feasible because the weight of the aircraft can prevent the removal of the tires. Furthermore, claiming that no maintenance is permitted during tire changes is inaccurate because such maintenance is routinely conducted and essential to aircraft safety.
