Failing to comply means the aircraft cannot legally fly. This particular AD addresses potential structural failures in the rudder (the part that steers the aircraft left and right), which could cause loss of control.\n\n**Key details:**\n- Based on **Beechcraft Service Instruction No. 0101-135**\n- The repetitive inspections are temporary — they stop once the modification is done\n- The modification has a hard deadline (1 August 1969)"}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-65-12-rudder-spar-and-hinges-inspection-and-modification","history":"/api/acts/ad-beech-65-12-rudder-spar-and-hinges-inspection-and-modification/history","analysis":"/api/acts/ad-beech-65-12-rudder-spar-and-hinges-inspection-and-modification/analysis","conflicts":"/api/acts/ad-beech-65-12-rudder-spar-and-hinges-inspection-and-modification/conflicts","importantCases":"/api/acts/ad-beech-65-12-rudder-spar-and-hinges-inspection-and-modification/important-cases","documents":"/api/acts/ad-beech-65-12-rudder-spar-and-hinges-inspection-and-modification/documents"}}
