Stephen Dickson

The FAA chief was on the hot seat during a Senate hearing Wednesday looking into reforming the certification process for new aircraft after the 737 MAX grounding.

Boeing Co. and the FAA are under intense scrutiny from Congress in the wake of the 737 MAX crashes. The House T&I Committee held its fifth hearing on the subject Dec. 11 in effort to tighten FAA certifications.

Dickson will take on oversight of Boeing 737 MAX grounding.
