Hi,
You know .. PF's actions may well be the result of his ignorance of the phenomenon that came to him.
His state of mind can be that of someone who does undestand nothing of what happend
And therefore he will do actions that are actually testing and according to results .. do other activities .. hoping that one of them will be good to solve the problem he could not analyze
OT .. but ...
This reminds me a auto crash stop on a diesel generator
The group suddenly stopped and the engineer in charge has undertaken many tests dismantling and replacement parts
Having to resume investigations .. I immediately understood by examining the log data measures engine parameters. that something unusual had happened at the oil system (temperature and pressure)
An worn lubricating oil pump was the problem and not the fuel injection system and turbo blowers that had been dismantled ...
The other mechanic was therefore not understood and therefore tried anything
If he was lucky .. it would have started with the oil system ..
This was not the case ....
A loss of 8 hours of time and money .
