Undetected cracking in the skin, the bulkhead outer chord, or the strap of the bulkhead outer chord in the above area, could progress into surrounding areas and result in reduced structural integrity of the support structure for the vertical or horizontal stabiliser and subsequent loss of control of the aircraft.This amendment allows the use of an FAA approved Alternative Method of Compliance (AMOC) to the requirements of this AD, without the need for the operator to continually apply for an exclusion for repairs that are already approved on a form 8100-9 as an AMOC by an FAA delegate. |\n\n| | The original issue of this directive became effective on 6 July 2006. |\n| --- | --------------------------------------------------------------------- |\n\n![](image.001.png) \nDavid Punshon \nDelegate of the Civil Aviation Safety Authority\n\n24 December 2008","sortOrder":0},{"sectionNumber":"AD/B767/222 Amdt 1","sectionType":"part","heading":"AD/B767/222 Amdt 1","content":"## AD/B767/222 Amdt 1","sortOrder":1},{"sectionNumber":"Station 1725.5 Area Cracking","sectionType":"part","heading":"Station 1725.5 Area Cracking","content":"## Station 1725.5 Area Cracking","sortOrder":2},{"sectionNumber":"2/2009","sectionType":"part","heading":"2/2009","content":"## 2/2009","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
