Titanium fasteners?
Does anyone have info on the normal maintenance cycle of the S92 MGB filter assembly? And particularly if it has been inadvertently accelerated because of increased attention given to other areas of the MGB. Just curious here about the frequency that the fasteners are removed and reinstalled.
I've been informed by an S92 pilot that there are other titanium studs/bolts that keep key components attached to the main gearbox, most notably the MGB oil pumps themselves. I do know that these pumps have an accelerated maintenance cycle mandated by an airworthiness directive so the attachment fixtures are obviously being loosened/torqued more often.
I wonder if anyone is concerned with these bolts and the possibility of fretting/galling of the titanium fasteners and possible failure? I don't know the number of bolts involved so it may not have as much potential.
