What should be done with weight and balance data if an aircraft undergoes maintenance?

When an aircraft undergoes maintenance, it's essential to review and update the weight and balance data to accurately reflect any changes that may have occurred as a result of the maintenance work. This is crucial because maintenance activities can involve replacing or removing components, adding equipment, or even making adjustments that can affect the aircraft's weight and center of gravity.

Accurate weight and balance data ensures that the aircraft operates safely within its performance limitations. Changes made during maintenance might not only alter the total weight but could also significantly impact the location of the center of gravity, which is vital for the aircraft's stability and maneuverability.

Keeping the weight and balance information updated helps in maintaining compliance with regulatory requirements and enhances operational safety. Therefore, it is important to assess the specifics of the maintenance performed and adjust the weight and balance records as necessary.
