On certain serial number aircraft, the manufacturer indicated that the fuel vent tube may have been installed incorrectly. As all affected aircraft would have been inspected, the unsafe condition no longer exists. |\n\n![](image.001.png)\n\nCharles Lenarcic  \nDelegate of the Civil Aviation Safety Authority\n\n20 December 2007","sortOrder":0},{"sectionNumber":"AD/CESSNA 207/17","sectionType":"part","heading":"AD/CESSNA 207/17","content":"## AD/CESSNA 207/17","sortOrder":1},{"sectionNumber":"Fuel Vent Tube","sectionType":"part","heading":"Fuel Vent Tube","content":"## Fuel Vent Tube","sortOrder":2},{"sectionNumber":"2/2008","sectionType":"part","heading":"2/2008","content":"## 2/2008","sortOrder":3}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":1474},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":false,"description":"This instrument simply cancels the previous directive entirely.

The manufacturer had identified that some fuel vent tubes were installed incorrectly, which could potentially cause safety issues.\n\n**Why it's being cancelled:** Since the rule is 30 years old, aviation safety authorities are satisfied that every affected aircraft has been inspected by now. The unsafe condition no longer exists, so the rule is unnecessary and is formally removed from the books.\n\n**Who it affects:** Owners and operators of Cessna 207 series aircraft. In practice, this cancellation simply tidies up the regulations by removing a requirement that everyone has already complied with years ago."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-207-17-fuel-vent-tube-cancelled","history":"/api/acts/ad-cessna-207-17-fuel-vent-tube-cancelled/history","analysis":"/api/acts/ad-cessna-207-17-fuel-vent-tube-cancelled/analysis","conflicts":"/api/acts/ad-cessna-207-17-fuel-vent-tube-cancelled/conflicts","importantCases":"/api/acts/ad-cessna-207-17-fuel-vent-tube-cancelled/important-cases","documents":"/api/acts/ad-cessna-207-17-fuel-vent-tube-cancelled/documents"}}
