Federal Aviation Administration head Steve Dickson will testify before a House transportation committee hearing on Wednesday morning, answering questions about the process of certifying the Boeing 737 Max.

A former Boeing employee turned whistleblower, Edward Pierson, is also scheduled to appear. Pierson raised concerns about conditions on Boeing's 737 production line in 2018.

Dickson, a former Delta Air Lines executive, took over the FAA in August, just five months after the second of two fatal 737 Max crashes. He has led the agency's response to criticism over the certification of the plane, which had been granted in 2017.

Wednesday's hearing is the first at which Dickson has testified about the plane. Boeing CEO Dennis Muilenburg and chief engineer John Hamilton testified before House and Senate committees earlier this fall.

Pierson spoke in public for the first time earlier this week in interviews with NBC News and The New York Times.

"What I witnessed firsthand, the chaos and the instability in the factory, is really unsettling to me as someone who's been around aircraft their entire life," he told The Times.

Several others are scheduled to testify.
