Aerospace supplier Hexcel says it’s yet to hear of any changes to the master production schedule for 737 output, but pledged not to be a bottleneck for planned rises at Boeing or Airbus. Still, the prospect of curtailed MAX output weighed on some suppliers, with Hexcel, Spirit AeroSystems and Montana Aerospace all shedding around 8%, and ATI down 5%. Boeing closed down almost 6%, pegging its market value decline since the Alaska Airlines incident around $30 billion.
