The FAA AD was originally issued to prevent flight in adverse weather conditions without a means of supply of electrical power to the deice system.             |\n|                | Whilst CASA acknowledges that currently there are no 340A model aeroplanes from the affected serial number range on the Australian register of aircraft, CASA is obliged to issue an AD reflecting the requirements of an AD issued by the State of Design, as an aeroplane from the affected serial number range may be imported into Australia at any time and that aeroplane may not be in compliance with FAAAD 80-19-10. |\n\n|     | Consequently this Directive is issued to reflect the terminating requirement of FAA AD 80-19-10. However, given the time since the FAA was issued and that currently no affected aircraft are in Australia, CASA has decided that the compliance should be ‘Prior to the issue of an Australian Certificate of Airworthiness’. |\n| --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |\n\n![](image.001.png)  \nJames Coyne  \nDelegate of the Civil Aviation Safety Authority\n\n21 April 2008","sortOrder":0},{"sectionNumber":"AD/CESSNA 340/36","sectionType":"part","heading":"AD/CESSNA 340/36","content":"## AD/CESSNA 340/36","sortOrder":1},{"sectionNumber":"Deice System Electrical Power","sectionType":"part","heading":"Deice System Electrical Power","content":"## Deice System Electrical Power","sortOrder":2},{"sectionNumber":"6/2008","sectionType":"part","heading":"6/2008","content":"## 6/2008","sortOrder":3}],"analysis":{"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This AD maintains its original narrow scope.
