The original rule required a one-time maintenance action on the **Primary and Auxiliary Servo Shut-off System**.\n\n**Who it affects**\nOwners and operators of Sikorsky S-62 series helicopters, as well as maintenance organisations working on these aircraft.\n\n**Why it matters**\nThe Civil Aviation Safety Authority withdrew the requirement because it was not actually mandated by the United States aviation authority (the country where these helicopters were designed). This cancellation removes the obligation for operators to complete that specific maintenance action, reducing regulatory burden while maintaining safety alignment with the country of design."}},"importantCases":[],"_links":{"self":"/api/acts/ad-s-62-1-primary-and-auxiliary-servo-shut-off-system-cancelled","history":"/api/acts/ad-s-62-1-primary-and-auxiliary-servo-shut-off-system-cancelled/history","analysis":"/api/acts/ad-s-62-1-primary-and-auxiliary-servo-shut-off-system-cancelled/analysis","conflicts":"/api/acts/ad-s-62-1-primary-and-auxiliary-servo-shut-off-system-cancelled/conflicts","importantCases":"/api/acts/ad-s-62-1-primary-and-auxiliary-servo-shut-off-system-cancelled/important-cases","documents":"/api/acts/ad-s-62-1-primary-and-auxiliary-servo-shut-off-system-cancelled/documents"}}
