This involved re-routing of cables and/or installation of centreline idler pulleys on certain aeroplanes. The routine inspections call for the installation of Service Kits to modify the system if premature wear is experienced at fuselage fairlead locations. Time intervals for inspections and replacement of cables were established to ensure integrity of the lateral control system.This amendment aligns the AD requirements and time limits for inspections and cable replacement with that of the FAA AD. Aileron cables are expected to wear beyond limits before the reaching the mandatory 500 hour life limit. |\n\n![](image.001.png)  \nDavid Punshon  \nDelegate of the Civil Aviation Safety Authority\n\n23 January 2009","sortOrder":0},{"sectionNumber":"AD/CESSNA 188/20 Amdt 2","sectionType":"part","heading":"AD/CESSNA 188/20 Amdt 2","content":"## AD/CESSNA 188/20 Amdt 2","sortOrder":1},{"sectionNumber":"Aileron Control Cables","sectionType":"part","heading":"Aileron Control Cables","content":"## Aileron Control Cables","sortOrder":2},{"sectionNumber":"3/2009","sectionType":"part","heading":"3/2009","content":"## 3/2009","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
