Dosed anyone know of any new rotorcraft which hasn't had some early teething problems?
I don't hear such issues about H175.
Moreover, I have heard that a 24 inches crack had been found on an AW189 mechanical deck in early 2015.
AW has always had crack on their new aircraft due to vibration management issues, remember AW139 tail boom cracks. However, the company know how to manage them and now the AW139 is one of the best helo. I think AW will do the same for the AW189
