There are more worrying things going on the aircraft world other than maintenance; what about fuel & oil supplies, airfields closing, lack of facilities and limited hours due rising costs.
There is not a lot of point there being plenty of oil, airfields and facilities if no one can afford to get airborne to use them. Maintenance is an equal part of that equation. Doing stuff for safety is one thing, doing needless work is another.
If we do not trust our engineers to make the correct decisions on what needs replacing then why license them in the first place?
The system of engineers making sensible decisions on what is required has served us well for decades. The FAA as IO freqently points out serves the vast majority of world aviation and they have been firm supporters on reviewing based on the condition rather than arbitrary figures.
My aircraft have operated perfectly safely for many years by allowing the engineers to do the job they have trained and become experienced in, I have seen no evidence that there is a safety case to support a change.
I have seen proof that these new costs are forcing people out of aviation. I have a friend who is facing an 8 grand annual to replace stuff that the engineers not him, deem to be perfectly serviceable. Seat belts are just one example, £1500 to change a set of serviceable belts.
Who would get the blame if your seatbelts failed in an accident? Not you but your maintenance person for not complying with the requirement
.
Tell me exactly how a serviceable set of seat belts are going to fail in an accident?
