The AD number is corrected from 91-117-025(B)R1 to 92-117-025(B)R1. There are no changes to the technical requirements of this AD.Airbus Industrie has reported cases of nose wheels rotating to 90 degrees on landing, causing significant damage to the wheel. This AD requires updating of the Brake/Steering Control Unit functional software which will prevent occurrences of a similar nature. |\n\n![](image.001.png)\n\nMike Higgins  \nDelegate of the Civil Aviation Safety Authority\n\n24 October 2013","sortOrder":0},{"sectionNumber":"AD/A320/27 Amdt 2","sectionType":"part","heading":"AD/A320/27 Amdt 2","content":"## AD/A320/27 Amdt 2","sortOrder":1},{"sectionNumber":"Nose Wheel Steering Control","sectionType":"part","heading":"Nose Wheel Steering Control","content":"## Nose Wheel Steering Control","sortOrder":2},{"sectionNumber":"22/2013","sectionType":"part","heading":"22/2013","content":"## 22/2013","sortOrder":3}],"analysis":{"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"Amendment 2 corrects a typographical error in the referenced DGAC AD number (changed from 91-117-025(B)R1 to 92-117-025(B)R1) and states explicitly that there are no changes to the technical requirements or applicability.
