Head of international 737 MAX review, NTSB chair to testify before Senate

The chair of a panel of international regulators that harshly criticised the FAA's certification of the now grounded Boeing 737 MAX will testify Tuesday before a Senate committee. Christopher Hart, a former NTSB chair who oversaw the review, will speak before the Senate Commerce Committee alongside current NTSB chairman Robert Sumwalt, the panel said Wednesday. They will appear after the testimony of Boeing CE Dennis Muilenburg and John Hamilton, who is VP and chief engineer for Boeing Commercial Airplanes. Muilenburg will then testify before a US House panel Wednesday. Congress is mulling changes to how the FAA delegates some certification tasks to manufacturers for new airplanes. In the 737 MAX certification it initially delegated 40% of the work to Boeing and later shifted more work to Boeing. <br/>
