Yes, but it's very long cycle failures at low frequency, and people suspect it's because of additional stress caused by winglets. Winglets reduce drag and save fuel, it's an important change. It may have been very difficult to predict and test this failure. And most importantly, the FAA and Boeing are handling it properly.

Winglets reduce drag and save fuel, it's an important change. It may have been very difficult to predict and test this failure. And most importantly, the FAA and Boeing are handling it properly. Cracks have been found in NGs both with and without winglets, so that is almost certainly not the issue at hand.
