WASHINGTON, April 11 (Reuters) - The U.S. Senate

Commerce Committee will hold a hearing on Wednesday with members

of an expert panel that released a report in February

criticizing Boeing's ( BA ) safety culture and calling for

significant improvements, the committee said on Thursday.

The hearing comes as the planemaker faces ongoing questions

about quality and safety practices following an Alaska Airlines

737 MAX 9 Jan. 5 mid-air emergency. The committee will

hear from three panel members, including a NASA expert on safety

culture and Javier de Luis, an aeronautics expert at MIT.
