What action should be taken when there is a difference of more than 5 pounds of air pressure in dual-mounted tires?

The correct action when there is a difference of more than 5 pounds of air pressure in dual-mounted tires is to correct the discrepancy and enter it in the aircraft records. This is essential for maintaining safety and regulatory compliance in aviation. Maintaining proper tire pressure is crucial because uneven tire pressures can lead to unpredictable handling characteristics, increased wear, and even tire failure, which poses significant risks during flight operations.

By correcting the discrepancy, you ensure that both tires are operating within the manufacturer's specified parameters, which contributes to optimal performance and safety. Documenting the correction in the aircraft records is also important because it provides a clear maintenance history, which can be referenced during future inspections and maintenance checks. This practice aligns with standard aviation maintenance protocols that emphasize the importance of record-keeping and accountability in aircraft maintenance.
