WASHINGTON, June 11 (Reuters) - President Donald Trump's nominee to head the Federal Aviation Administration vowed to hold Boeing BA.N 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 "accountable to deliver a high quality product safely... We can also help Boeing 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 move the process along a little bit quicker."
