Compliance:

For Requirements 1 and 2 - Within 30 days after the effective date of this Directive or prior to the issue of a Certificate of Airworthiness, whichever occurs later.

This Airworthiness Directive becomes effective on 13 July 2007.

\n```\n\n| Background: | The FAA ADs listed in Table 1 of this Directive require one time actions for which the compliance date and/or period has passed. CASA has determined that these ADs may be applicable to recently registered or imported Australian aircraft. This Directive is issued to ensure all State of Design ADs are complied with. |\n| ----------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| | CASA appreciates that, due to date of aircraft manufacture or aircraft configuration and modification status, not all the ADs listed in Table 1 will be applicable to all GIV-X, GV and GV-SP series aeroplanes. |\n\n![](image.001.png) \nDavid Punshon \nDelegate of the Civil Aviation Safety Authority\n\n21 June 2007","sortOrder":0},{"sectionNumber":"AD/G1159/46","sectionType":"part","heading":"AD/G1159/46","content":"## AD/G1159/46","sortOrder":1},{"sectionNumber":"State of Design Airworthiness Directives","sectionType":"part","heading":"State of Design Airworthiness Directives","content":"## State of Design Airworthiness Directives","sortOrder":2},{"sectionNumber":"8/2007 DM","sectionType":"part","heading":"8/2007 DM","content":"## 8/2007 DM","sortOrder":3}],"analysis":{"flash_summary":{"complexity_score":4,"scope_assessment":{"changed":true,"description":"The Directive applies FAA State‑of‑Design ADs to Australian‑registered Gulfstream GIV‑X, GV and GV‑SP aeroplanes that may have missed the FAA compliance windows.
