CHANGE: Airbus Poised to Overtake Boeing as Biggest Plane Maker.

The U.S. aerospace giant’s best-selling MAX has been barred by safety regulators from flying passengers for almost four months, far longer than Boeing, its investors and airlines expected. Consumers have expressed misgivings about getting on the plane again, and a dearth of new sales to carriers has helped drain about $50 billion from Boeing’s market value since it peaked in March.

The company’s delivery slump has reverberated across an aerospace industry that had been enjoying an unprecedented decadelong boom. Some suppliers have been forced to trim output and idle staff, while airlines have had to cancel thousands of flights and seek compensation from the plane maker.

More than 150 undelivered MAX jets are parked at sites around the U.S., along with the 380 in airlines’ hands that were grounded by regulators in March.

Ouch.
