The head of the Federal Aviation Administration will face questions about whether the agency is too cozy with Boeing when he testifies this week before a congressional panel. The chairman of the House Transportation Committee says he plans to ask FAA Administrator Stephen Dickson about Boeing’s influence over the FAA’s Seattle office and incidents in which FAA managers vetoed the concerns of the agency’s own safety experts. “We are having a hard time piercing the veil of how consistently and repeatedly Boeing is managing to pressure and overcome the objectives of the safety specialists,” committee Chairman Peter DeFazio, D-Ore., said Monday in an interview. Dickson is scheduled to testify at a hearing Wednesday, just as the FAA gears up to review changes Boeing is making in its 737 Max jet.
