Perhaps depends on your engineer. I used to own a PA38 that had a broken engine mounting frame spotted at a 50hr (analysis showed failed in overload with no pre-existing defect so presumably a very hard and unreported landing). Also had strange creaking noise that was traced to undercarriage leg mounting bolts but as part of that investigation found wing spar web corrosion (required a re-wing!)
Neither obviously part of the LAMS so I put it down to having a bl&*dy good engineering organisation.
And incase you ask - Tayside Aviation at Dundee.
