WASHINGTON—The acting chief of the Federal Aviation Administration defended his agency’s safety certification of the Boeing 737 Max jetliner, the plane involved in two deadly crashes, and the FAA’s decision not to ground the jet until other regulators around the world had already done so.
During a congressional hearing Wednesday, the FAA official, Daniel Elwell, also stood by the agency’s decades-old policy of using employees of aircraft manufacturers like Boeing to conduct inspections on their own companies’ work.
