Abstract: A maintenance method for servicing a component includes generating, via an electronic control unit, a digital model of the component, detecting, via the electronic control unit, a defect of the component, classifying, via the electronic control unit, the defect as a defect type, and evaluating the defect to determine, according to the defect type, whether to repair the defect or to replace a section of the component containing the defect. A maintenance system for servicing components may include a scanner and an ECU configured to create a digital model of a component, detect a defect of the component from the digital model and/or three-dimensional data of the component, classify the defect as a defect type of a plurality of defect types, and/or evaluate the defect according to the defect type.

Abstract: An actuator includes an end fitting, a ball screw connected to the end fitting, a ball nut engaged with the ball screw, a rod disposed at least partially within the ball screw, and a rotating member engaged with the rod. A method of verifying an actuator may include rotating a manual input portion in a first direction under substantially no load until the manual input portion stops, rotating the manual input portion in a second, opposite direction until a first torque is measured, determining a first rotational angle at which the first torque was measured, rotating the manual input portion in the first direction until a second torque is measured, determining a second rotational angle at which the second torque was measured, and verifying a second load path if a backlash is within a predetermined range.
