I remember a training seminar at an airline I worked as a mechanic,that covered the importance of completing all work to specs,and the proper sign offs required.
The accident was a Nationair DC8 that had wheel failure on the taxi out and subsequent inflight fire and crash,The tire pressures had been "pencil whipped" by a manager,and the results were human lives lost.
