You cannot fly the aircraft until this modification is done. There are no extensions or grace periods.\n\n**Why it matters:**\nAirworthiness Directives are issued when safety regulators identify a mechanical defect or unsafe condition that could endanger flight safety. This directive addresses a specific problem with the rotor blade hinge on early-model B-2 helicopters."}},"importantCases":[],"_links":{"self":"/api/acts/ad-b-2-10-rotor-blade-hinge-modification","history":"/api/acts/ad-b-2-10-rotor-blade-hinge-modification/history","analysis":"/api/acts/ad-b-2-10-rotor-blade-hinge-modification/analysis","conflicts":"/api/acts/ad-b-2-10-rotor-blade-hinge-modification/conflicts","importantCases":"/api/acts/ad-b-2-10-rotor-blade-hinge-modification/important-cases","documents":"/api/acts/ad-b-2-10-rotor-blade-hinge-modification/documents"}}
