The original compliance date remains unchanged.This Directive requires modification of the right main landing gear and auto-speedbrake control system to provide an air/ground signal to the system. The modification provides a second air/ground signal to the auto-speedbrake control system, which is designed to prevent uncommanded deployment of the auto-speedbrake spoilers during flight. Uncommanded deployment of the auto-speedbrake spoilers could result in reduced controllability of the aeroplane. |\n\n![](image.001.png)  \nMike Higgins  \nDelegate of the Civil Aviation Safety Authority\n\n25 June 2013","sortOrder":0},{"sectionNumber":"AD/B767/178 Amdt 1","sectionType":"part","heading":"AD/B767/178 Amdt 1","content":"## AD/B767/178 Amdt 1","sortOrder":1},{"sectionNumber":"Auto-Speedbrake Control System","sectionType":"part","heading":"Auto-Speedbrake Control System","content":"## Auto-Speedbrake Control System","sortOrder":2},{"sectionNumber":"14/2013","sectionType":"part","heading":"14/2013","content":"## 14/2013","sortOrder":3}],"analysis":{"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This amendment maintains the original scope.
