Zusammenfassung:	A ballscrew assembly for an actuator is provided. In an embodiment, the ballscrew assembly includes a ball nut assembly including a view port; a ballscrew provided within at least a portion of the ball nut assembly; an inner rod provided within the ballscrew in the direction of the longitudinal axis, the inner rod including an enlarged end portion; and a compression mechanism, such that at least a portion of the compression mechanism is provided between the enlarged end portion and the ballscrew. In another embodiment the assembly is configured such that when the inner rod is in a failed state, the compression mechanism provides a force that moves the visual indicator toward the view port. In another embodiment, the assembly includes a proximity sensor in addition to, or in lieu, of a view port to detect a failure.
