This Airworthiness Directive becomes effective on 26 July 2000.\n\nBackground: The French Direction Generale de L’Aviation Civile has advised that an electrostatic ground connector on several ferry fuel tanks was not electrically bonded to its support. During refuelling of a tank, the absence of this electrical bonding could generate an electrical arc between the refuelling nozzle of the tanker and the fuel tank causing the fuel tank to explode.\n\n![Signature of Eugene Paul Holzapfel, Delegate of the Civil Aviation Safety Authority.](image.003.png)  \n\nEugene Paul Holzapfel\n\nDelegate of the Civil Aviation Safety Authority 18 July 2000\n\n![](image.002.png)  \n\nThe above AD is notified in the Commonwealth of Australia Gazette on 26 July 2000.","sortOrder":1}],"analysis":{"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The directive applies only to specified AS350 models and the listed metal ferry fuel tank part numbers.
