These measures are intended to decrease the likelihood of uncommanded roll during approach and landing when residual ice is present or can be expected.\n\n![Signature of Bernard Malcolm Hole Delegate of the Civil Aviation Safety Authority](image.003.png)  \n\nBernard Malcolm Hole\n\nDelegate of the Civil Aviation Safety Authority 9 March 2000\n\n![](image.002.png)  \n\nThe above AD is notified in the Commonwealth of Australia Gazette on 15 March 2000.","sortOrder":0}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
