New engineering data showed that cracks in this part grow very slowly and will be caught during normal scheduled maintenance anyway. Therefore, the extra safety rule is no longer needed. This saves operators time and money while maintaining safety standards.\n\n**Key date:** The cancellation took effect on 28 September 2006."}},"importantCases":[],"_links":{"self":"/api/acts/ad-dauphin-82-main-rotor-rotating-star-cancelled","history":"/api/acts/ad-dauphin-82-main-rotor-rotating-star-cancelled/history","analysis":"/api/acts/ad-dauphin-82-main-rotor-rotating-star-cancelled/analysis","conflicts":"/api/acts/ad-dauphin-82-main-rotor-rotating-star-cancelled/conflicts","importantCases":"/api/acts/ad-dauphin-82-main-rotor-rotating-star-cancelled/important-cases","documents":"/api/acts/ad-dauphin-82-main-rotor-rotating-star-cancelled/documents"}}
