If footbar eyebolts on the flight suits are found to be attached with a standard hex nut instead of the required locknut, what is the status of the flight suits?

The correct choice indicates that the flight suits may continue to be used, but they require inspections after each flight. This is because the use of a standard hex nut instead of a locknut compromises the safety and reliability of the attachment. Locknuts are specifically designed to resist loosening under vibration and stress, which is particularly important in applications like skydiving equipment where safety is paramount.

By allowing continued use with inspections, the emphasis is placed on ensuring safety measures are in place. Inspections can help identify any potential issues that may arise from the use of the standard hex nut, allowing the operator to monitor the condition of the flight suits closely. Thus, it's crucial that any findings from the inspections are acted upon, which is a proactive approach to maintaining safety in this context.
