Zusammenfassung:	A variable area fan nozzle actuation ("VAFN") system is disclosed. The VAFN system may include an electrohydrostatic actuator ("EHA") arranged to translate a VAFN panel relative to a translating sleeve. An electrical coupling may extend between a translating sleeve associated with the VAFN system and the fixed structure. The electrical coupling may be movable so that as the translating sleeve and fixed structure move relative to each other, power may be provided to the EHA by a wiring harness extending across the space between the translating sleeve and the fixed structure and connecting the EHA to an EHA power source.
