What condition is checked regarding yoke and clevis assembly?

The condition that is checked regarding the yoke and clevis assembly is the securing of the jam nut. This is crucial because the jam nut plays a vital role in ensuring that the clevis pin remains securely in place. If the jam nut is not properly secured, there is a risk that the clevis pin could loosen during operation, potentially leading to failure of the assembly and jeopardizing safety. Regular inspection for the tightness and security of this component is an essential part of maintaining the yoke and clevis assembly in safe working condition.

In contrast, while the length of the clevis pin is relevant for compatibility with the assembly, it does not directly impact the operational safety as crucially as the securing of the jam nut. The color of the assembly does not typically pertain to its functionality or safety, and the age of the components might be considered during maintenance checks, but it is not a specific condition to be checked for immediate safety concerns related to the assembly's operation.
