In the extreme tip-back condition, the forward and mid-cabin exits could result in steeper sliding angles, which could cause injury to passengers and crewmembers during an emergency evacuation. |\n\n![](image.001.png)  \nDavid Villiers  \nDelegate of the Civil Aviation Safety Authority\n\n30 September 2009","sortOrder":0},{"sectionNumber":"AD/B767/254","sectionType":"part","heading":"AD/B767/254","content":"## AD/B767/254","sortOrder":1},{"sectionNumber":"Door Mounted Escape Slides and Slide Raf","sectionType":"part","heading":"Door Mounted Escape Slides and Slide Rafts","content":"## Door Mounted Escape Slides and Slide Rafts","sortOrder":2},{"sectionNumber":"12/2009","sectionType":"part","heading":"12/2009","content":"## 12/2009","sortOrder":3}],"analysis":{"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The directive does not expand or narrow the technical scope; it adopts the FAA AD requirements for the specified 767‑200/300 fleet.
