US regulators said on Wednesday that Boeing must address a new “potential risk” in the Boeing 737 MAX, further clouding the timeframe for resuming service on the planes after two deadly crashes.
The issue, which surfaced during FAA simulator testing, concerns the ability of pilots to quickly reassert control of the plane if an automated flight handling system pushes the plane downward, said a person familiar with the matter.
The Federal Aviation Administration “will lift the aircraft’s prohibition order when we deem it is safe to do so,” the agency said in an email.
