Boeing’s share price fell sharply on Monday, in the first trading session after part of the fuselage of one of its 737 Max 9 jets blew out on an Alaska Airlines flight on Friday night.
Boeing’s share prices fell about 8 percent, and Spirit AeroSystems, which made the door plug that was torn from the plane, saw its stock drop by about 11 percent by the end of the day on Monday.
The Alaska Airlines flight departing from Portland, Ore., lost the mid-cabin door plug midair, exposing passengers to howling winds and forcing an emergency landing. None of the 171 passengers and six crew members aboard were seriously injured.
The Federal Aviation Administration has ordered U.S. airlines to ground certain Boeing 737 Max 9 planes configured similarly to the one used by Alaska. The National Transportation Safety Board is investigating the incident.
