WASHINGTON, June 11 (Reuters) - President Donald Trump's

nominee to head the Federal Aviation Administration vowed to

hold Boeing ( BA ) accountable after a series of safety issues

have raised questions about the U.S. planemaker.

Republic Airways CEO Bryan Bedford said at a Senate Commerce

confirmation hearing there were "some really hard lessons

learned" by the FAA about the failure of a key safety system

tied to two fatal Boeing 737 MAX crashes in 2018 and 2019 that

killed 346 people. Bedford vowed to hold Boeing ( BA ) "accountable to

deliver a high quality product safely... We can also help Boeing ( BA )

by not simply saying, 'This fails.' We can collaborate and tell

them where the failures are and how we view remedies that can

help Boeing ( BA ) move the process along a little bit quicker."
