Since Boeing manufactured the plane, it's basically their problem -
no matter who they contract to supply parts.

The MAX software might not be the only problem that Boeing will have
with the Max.
737 NGs are suffering premature fatigue cracks with the pickle forks -
these are what hold the wings to the body of the aircraft.
These fatigue cracks are occurring after some 30,000 flights,
which is about half of the design life of some 60,000 flights.

The MAXes have larger and more powerful engines that may stress the
wings more than the earlier engines.  This may result in fatigue cracks
appearing even earlier than on the NG's.
