I imagine like any kind of metal fatigue, there should be some warning signs, right?

The odds are you are already having warning signs. Under normal running conditions the A frame doesn't break which makes me believe you would be experiencing vibration problems that are not addressed. So as the crack propagates it is likely you start experiencing RF problems. The question is will you ignore them before it is too late?

...but until people started putting the Zimmerman rear mount muffler on the Spectra, nobody was having problems with cracked A-frames, right? And nobody has yet to document a cracked A-frame on the front, right? It is only the back which is cracking? And only with people who are using the Zimmerman rear-mount muffler?

Correct me if I'm wrong.

Well I was certainly running the rear mount Zimmerman on mine when it cracked. I shall be ordering my spares from Helipros as I've given up waiting for Motors&Rotors to come back to me with prices and availability of the parts I need.
Once it's rebuilt it will be up for sale as I really CBA to put up with the hassles involved.
