The exact steps aren't detailed in the directive itself; instead, operators must follow the instructions in **Beechcraft Service Bulletin 95-55 No. 4** (a technical notice issued by the manufacturer).\n\n**Why it matters:**\nThis directive addresses a potential structural or safety issue with that specific part of the aircraft. Failure to comply could affect the airworthiness and safety of the aircraft.\n\n**Compliance deadline:**\nThe work had to be completed before 1 September 1971."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-55-2-rib-in-area-adjacent-to-rudder-torque-tube","history":"/api/acts/ad-beech-55-2-rib-in-area-adjacent-to-rudder-torque-tube/history","analysis":"/api/acts/ad-beech-55-2-rib-in-area-adjacent-to-rudder-torque-tube/analysis","conflicts":"/api/acts/ad-beech-55-2-rib-in-area-adjacent-to-rudder-torque-tube/conflicts","importantCases":"/api/acts/ad-beech-55-2-rib-in-area-adjacent-to-rudder-torque-tube/important-cases","documents":"/api/acts/ad-beech-55-2-rib-in-area-adjacent-to-rudder-torque-tube/documents"}}
