The AD compliance was within 50 hours time in service after 13 August 1980. As all aircraft would have now been modified, the AD is no longer required. |\n\n![](image.001.png)\n\nJames Coyne  \nDelegate of the Civil Aviation Safety Authority\n\n25 July 2008","sortOrder":0},{"sectionNumber":"AD/CESSNA 400/74","sectionType":"part","heading":"AD/CESSNA 400/74","content":"## AD/CESSNA 400/74","sortOrder":1},{"sectionNumber":"Fuel Pressure Switch Line - Inspectionan","sectionType":"part","heading":"Fuel Pressure Switch Line - Inspectionand Modification","content":"## Fuel Pressure Switch Line - Inspection  \nand Modification","sortOrder":2},{"sectionNumber":"10/2008","sectionType":"part","heading":"10/2008","content":"## 10/2008","sortOrder":3}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":1630},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":false,"description":"This instrument formally terminates the airworthiness directive upon completion of its safety purpose.

Because all affected aircraft have now had the required modification done, the rule is obsolete.\n*   **Effective date:** The cancellation took effect on 25 September 2008.\n\nThis is routine housekeeping by the Civil Aviation Safety Authority (CASA) to remove outdated requirements from the rulebooks."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-400-74-fuel-pressure-switch-line-inspection-and-modification-cancelled","history":"/api/acts/ad-cessna-400-74-fuel-pressure-switch-line-inspection-and-modification-cancelled/history","analysis":"/api/acts/ad-cessna-400-74-fuel-pressure-switch-line-inspection-and-modification-cancelled/analysis","conflicts":"/api/acts/ad-cessna-400-74-fuel-pressure-switch-line-inspection-and-modification-cancelled/conflicts","importantCases":"/api/acts/ad-cessna-400-74-fuel-pressure-switch-line-inspection-and-modification-cancelled/important-cases","documents":"/api/acts/ad-cessna-400-74-fuel-pressure-switch-line-inspection-and-modification-cancelled/documents"}}
