In an Oct. 12 letter to Boeing from FAA official Ian Won
seen by Reuters, the agency asked Boeing to reassess some assertions that hazards classified as catastrophic “do not contain human factors assumptions.”
The FAA also said it was unable to complete some reviews of Boeing submissions “due to missing and incomplete information regarding human factors assumptions in catastrophic hazard conditions.”
Boeing faces a late December deadline for the FAA to certify the MAX 7 and MAX 10 or it must meet new modern cockpit alerting standards that could significantly delay the airplanes unless the company receives a waiver from Congress.
