The early years of ANY aircraft is riddled with teething issues - some serious, some not so serious and sadly, some continually. But the one thing any OEM can’t do is tell the future for all operators - who all operate with different envelopes, equipment, enviroment, methods, weather and particular situations. One size does not fit all.
The maintenance systems you use have worked and they have raised the issue of cracks in the same areas - pooh happens! A repair will soon be formulated and some of your aircraft will be back on your Lines soon enough. Wait till your told you can fly again and stop wingeing….sit in the Sims for a while and dream of being a winged god another time.
