Maintain Minimum Weight

All repairs must be kept to a minimum weight. Keep the patch size as small as practicable and limit the number of rivets to what is necessary. In many cases, repairs disturb the structure's original balance. By adding weight in each repair, a control surface becomes so unbalanced that the trim and balance tabs will require adjusting.
