WASHINGTON, Oct 23 (Reuters) - The chair of a panel of international regulators that harshly criticized the Federal Aviation Administration's certification of the now grounded Boeing 737 MAX will testify Tuesday before a Senate committee, a statement from the committee showed.
Christopher Hart, a former National Transportation Safety Board chair who oversaw the review, will speak before the Senate Commerce Committee alongside current NTSB chairman Robert Sumwalt.
They will appear after the testimony of Boeing Co chief executive Dennis Muilenburg and John Hamilton, who is vice president and chief engineer for Boeing Commercial Airplanes. Muilenburg will then testify before a House panel on Wednesday. (Reporting by David Shepardson; Editing by Jan Harvey)
