After 16 years, the Civil Aviation Safety Authority (CASA) determined the rule was no longer relevant to current flight safety. Cancelling it removes unnecessary regulatory burden while maintaining safety standards."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-222-16-tail-rotor-boost-cylinder-support-bracket-cancelled","history":"/api/acts/ad-bell-222-16-tail-rotor-boost-cylinder-support-bracket-cancelled/history","analysis":"/api/acts/ad-bell-222-16-tail-rotor-boost-cylinder-support-bracket-cancelled/analysis","conflicts":"/api/acts/ad-bell-222-16-tail-rotor-boost-cylinder-support-bracket-cancelled/conflicts","importantCases":"/api/acts/ad-bell-222-16-tail-rotor-boost-cylinder-support-bracket-cancelled/important-cases","documents":"/api/acts/ad-bell-222-16-tail-rotor-boost-cylinder-support-bracket-cancelled/documents"}}
