We had problems with MFD/PFD blackout and the change of relay helped but we didn't had the information of the location of the relay so we end up in a wrong place where was also a relay K19. If I can remember correctly it was in the ceiling at the end of the cabin. We had to find out ourselves that it was in cockpit overhead panel. One of the chopter's MFD still changes its brightness (very qiuckly from max to min and back again). It has happened on the ground and during a flight but then it works correctly for weeks.
One chopter has had one main tire changed so generally we don't have problems with these and we have main tire pressure 210psi
According to log books we haven't had problems with ILS at all but there's still a chance I missed it so I have to look again these.
Squelch break sounds intresting for me. I'll try to find out at some time if our chopters occurs that problem. So far I have heard nothing about it.
