A turnbuckle on a 5/32 cable, safetied with a single wrap of stainless steel wire, must have wire of at least what diameter?

The correct answer is based on the requirements outlined in the regulations and guidelines for safetying turnbuckles. For a 5/32 inch cable, the general rule is that the safety wire used should be no less than one-half of the diameter of the wire being secured. Since a 5/32 inch cable is equivalent to approximately 0.156 inches, the diameter of the safety wire should be chosen to ensure adequate strength and safety.

When calculating for safety wire, using a diameter of .057 inches provides sufficient strength and meets the safety standards. This ensures that the turnbuckle remains securely fastened during operation, even under tension. Using wire that is too thin could compromise the integrity of the safetying process, leading to potential failures.

The required safety wire diameter is critical for maintaining airworthiness and ensuring that components do not loosen during flight. Adhering to these specifications is essential for compliance with maintenance and operational safety standards in aviation.
