The AD compliance was before 1 October 1973.

This was a safety measure to prevent fuel leaks.\n\n**Why it's being cancelled:** Aircraft owners had to complete this inspection by 1 October 1973 — more than 35 years ago. Since every affected aircraft would have been inspected long ago, the rule is now redundant and is being removed from the books.\n\n**Who it affects:** Owners and operators of Cessna 400 series aircraft (who no longer need to comply with this specific requirement)."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-400-36-wing-leading-edge-fuel-line-inspection-cancelled","history":"/api/acts/ad-cessna-400-36-wing-leading-edge-fuel-line-inspection-cancelled/history","analysis":"/api/acts/ad-cessna-400-36-wing-leading-edge-fuel-line-inspection-cancelled/analysis","conflicts":"/api/acts/ad-cessna-400-36-wing-leading-edge-fuel-line-inspection-cancelled/conflicts","importantCases":"/api/acts/ad-cessna-400-36-wing-leading-edge-fuel-line-inspection-cancelled/important-cases","documents":"/api/acts/ad-cessna-400-36-wing-leading-edge-fuel-line-inspection-cancelled/documents"}}
