This component transmits control inputs from the rudder pedals to the rudder itself (the moving part on the tail that steers the aircraft left and right).\n\n**Specific action:** Follow the instructions in Beechcraft Service Bulletin 95-55 No. 11 or 95-A55 No. 5. These are manufacturer-issued technical documents detailing the required inspection or repair procedure.\n\n**Deadline:** You must complete this action within 200 hours of flight time ('time in service') counted from 1 September 1971.\n\n**Why it matters:** This prevents potential failure of the rudder control system, which is essential for safe steering of the aircraft during flight."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-55-3-rudder-torque-tube","history":"/api/acts/ad-beech-55-3-rudder-torque-tube/history","analysis":"/api/acts/ad-beech-55-3-rudder-torque-tube/analysis","conflicts":"/api/acts/ad-beech-55-3-rudder-torque-tube/conflicts","importantCases":"/api/acts/ad-beech-55-3-rudder-torque-tube/important-cases","documents":"/api/acts/ad-beech-55-3-rudder-torque-tube/documents"}}
