Text in force at CAR3-14: from CAR3-0, effective 1 Nov 1949. OCR text
When wires are used for external lift bracing they shall be double unless the design provides for a lift-wire-cut condition. Rigging loads shall be taken into account in a rational or conservative manner. The end connections of brace wires shall be such as to minimize restraint against bending or vibration. When brace struts of large fineness ratio are used, the aerodynamic forces on such struts shall be taken into account.
