ABSTRACT
As we know from previous publications the item is initialised by start power. Upgraded in the manufacturing technology resulted in some changed of item’s features. Of course this situation resulted in the production of many tens of thousands of newly manufactured items where the technology was different. The non-compliance between the previously made and currently produced items has not been observed and investigated deeply in all possible consequences like dependability and safety. Most of the attention was paid to the performance. However, most of the items manufactured this way/using new technology have been mounted in systems and they have been in operation.
