Boeing to change quality controls for 737 MAX, open factories to greater scrutiny  

Boeing is to implement changes to quality control procedures for the 737 MAX 9 after an Alaska Airlines aircraft lost its door plug mid-flight and suffered an explosive decompression. The manufacturer is to add more inspections at its own factory and at Spirit Aerosystems, a key supplier that installs door plugs on unused emergency exits on certain models of the MAX. Both parties will also open their factories to greater scrutiny by airlines who fly the type. “The AS1282 accident and recent customer findings make clear that we are not where we need to be,” said Stan Deal, chief executive
