The inspections must follow Bell Helicopter's Service Bulletin No. 205-05-73-5 and began on 31 October 1973. This safety measure helps prevent mechanical failure in the tail rotor system, which is critical for helicopter control.\n\n**Who it affects:** Operators of Bell 205A-1 helicopters with a specific tail rotor hub part.\n\n**What you must do:** Inspect the tail rotor hub assembly according to the manufacturer's service bulletin at least every 25 hours of flight time."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-205-15-tail-rotor-hub-assembly-inspection","history":"/api/acts/ad-bell-205-15-tail-rotor-hub-assembly-inspection/history","analysis":"/api/acts/ad-bell-205-15-tail-rotor-hub-assembly-inspection/analysis","conflicts":"/api/acts/ad-bell-205-15-tail-rotor-hub-assembly-inspection/conflicts","importantCases":"/api/acts/ad-bell-205-15-tail-rotor-hub-assembly-inspection/important-cases","documents":"/api/acts/ad-bell-205-15-tail-rotor-hub-assembly-inspection/documents"}}
