After Boeing Max crashes, US regulators detail safety information that aircraft makers must disclose

The Federal Aviation Administration, which was heavily criticized for the way it approved the Boeing 737 Max before two deadly crashes, says it is more clearly explaining the kind of critical safety information that must be disclosed to the agency.

The FAA said Wednesday that two draft policy documents spell out the process for considering certification of new, large passenger planes.

The documents also guide manufacturers on disclosing any design changes that significantly affect information already submitted to FAA, the agency said.

It is generally accepted in the aviation industry that certification of new planes will be more difficult and take longer after the Boeing Max debacle.
