The cancellation took effect on 4 June 2009.\n\n**Who it affects**\n\nThis applies to owners, operators, and maintenance engineers responsible for **Fairchild (Swearingen) SA226 and SA227 series aeroplanes**.\n\n**Why it matters**\n\nThe original rule was emergency legislation responding to a manufacturer’s service bulletin warning about potential defects. Because compliance was mandatory within 10 hours of flying time back in 1973, every affected aircraft would have been inspected and repaired decades ago. This cancellation cleans up the statute book by removing a redundant requirement, ensuring operators no longer need to track an obsolete rule that serves no remaining safety purpose."}},"importantCases":[],"_links":{"self":"/api/acts/ad-swsa226-12-rudder-bellcranks-inspection-cancelled","history":"/api/acts/ad-swsa226-12-rudder-bellcranks-inspection-cancelled/history","analysis":"/api/acts/ad-swsa226-12-rudder-bellcranks-inspection-cancelled/analysis","conflicts":"/api/acts/ad-swsa226-12-rudder-bellcranks-inspection-cancelled/conflicts","importantCases":"/api/acts/ad-swsa226-12-rudder-bellcranks-inspection-cancelled/important-cases","documents":"/api/acts/ad-swsa226-12-rudder-bellcranks-inspection-cancelled/documents"}}
