5 hull losses in less than a year. Makes one wonder.
Aging aircraft, etc so yeah, maybe.
I have flown twice on a 154 and thought it was a pretty solid bit of kit. Only complaint I had was when I nearly got deafened taking a leak in the rear head, next to the powerplants.
I suspect the problem is that some companies are pushing this graceful aircraft to unacceptable limits. Like any lady, if you don't look after her she will bite back and then some.
