Inspection of other aircraft at PAC revealed all had correct specification rivets. As this rivet error could have occurred in earlier production aircraft, this Directive requires a detailed inspection of certain fuselage top rivets. |\n\n![](image.001.png)  \nDavid Villiers  \nDelegate of the Civil Aviation Safety Authority\n\n13 September 2006","sortOrder":0},{"sectionNumber":"AD/750XL/8","sectionType":"part","heading":"AD/750XL/8","content":"## AD/750XL/8","sortOrder":1},{"sectionNumber":"Fuselage Roof, Station 180.85","sectionType":"part","heading":"Fuselage Roof, Station 180.85","content":"## Fuselage Roof, Station 180.85","sortOrder":2},{"sectionNumber":"11/2006","sectionType":"part","heading":"11/2006","content":"## 11/2006","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.
