That would be ridiculously expensive. We choose to take good care of the one that we have. All of our priority is in keeping our only car in good running condition. Personnel avoidable events are actions that the human being takes to reduce the risk of reaching design life. Bearings are rather simple components when you look at their manufacture and structure.
Bearings are precision components that are subjected to imperfect environments.
If we reflect on these causes, you can see the influence that the human being has on reducing equipment life. If we can agree that any failure is typically the result of an error of omission or commission by a human being, then we should be able to apply precision concepts to this decision-making process. Human decision errors are usually a result of poor information to make a good decision. For instance, if bearings are failing due to misalignment, does the problem go away if we get an outside contractor to come in and align this one time. We must find out why the maintenance person that aligned the equipment originally did not align it correctly.
