True or False: A cotter pin should not be re-used if the tines have been bent previously.

A cotter pin should not be re-used if the tines have been bent previously because bending can compromise its structural integrity and reliability. Cotter pins are designed to secure components by preventing them from loosening under operational conditions. When the tines are bent, they may not hold the same clamping force or fit as intended, potentially leading to failure of the assembly where they are used.

Re-using a bent cotter pin introduces risk into the assembly process, which is critical in aerospace applications where safety and reliability are paramount. Proper maintenance and adherence to safety protocols dictate that cotter pins should be replaced if they show any signs of deformation or damage, ensuring that the mechanical connections remain secure and operative.
