This Directive requires sleeving of the standby power feeder cable. This action is intended to prevent damage to the 90-minute APU standby power feeder cable, which could result in arcing between the standby power feeder cable and the shroud of the APU fuel line, penetration of the fuel line shroud, and a consequent fire in the main deck floor above the aft cargo compartment.\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 13 November 2000\n\n![](image.002.png)  \n\nThe above AD is notified in the Commonwealth of Australia Gazette on 22 November 2000.","sortOrder":1}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
