This week's Aviation Week & Space Technology paints a bleak picture of the program: flight-test aircraft are 12 tons overweight, with the payload of production aircraft expected to be at least 5 tons under spec. And in addition to the FADEC issues, cracks have now been found in engine gearbox casings, requiring strengthening.

The most serious claim made by Av Week is that 'Sarajevo profile' steep approaches may not be possible "because of possible flutter issues with the propellers." If true, look for Boeing to capitalize on the loss of one of the underlying prop vs. fan arguments.
