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 185/29","sectionType":"part","heading":"AD/CESSNA 185/29","content":"## AD/CESSNA 185/29","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":2532},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":false,"description":"This cancellation is consistent with the original regulatory intent of maintaining safety only while risks exist.

However, after nearly 30 years, aviation safety authorities confirm that every affected aircraft has already been inspected and fixed. Since the safety risk no longer exists, the inspection requirement is being removed to reduce unnecessary regulatory burden on aircraft owners and operators.\n\nThe cancellation takes effect on 14 February 2008."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-185-29-fuel-vent-tube-cancelled","history":"/api/acts/ad-cessna-185-29-fuel-vent-tube-cancelled/history","analysis":"/api/acts/ad-cessna-185-29-fuel-vent-tube-cancelled/analysis","conflicts":"/api/acts/ad-cessna-185-29-fuel-vent-tube-cancelled/conflicts","importantCases":"/api/acts/ad-cessna-185-29-fuel-vent-tube-cancelled/important-cases","documents":"/api/acts/ad-cessna-185-29-fuel-vent-tube-cancelled/documents"}}
