Boeing Co. is facing a growing crisis of confidence over its 737 Max jet, as airlines and regulators from Singapore to Australia move to ground or block the plane following two deadly crashes in five months.
A day after U.S. regulators stood by the jet’s airworthiness, airlines and aviation authorities in South America and Asia are instead opting for a zero-risk approach. Australia followed Singapore in temporarily barring the 737 Max from its airspace, meaning the newest version of Boeing’s best-selling model is now blocked from a key long-distance travel destination as well as Changi, Asia’s second-busiest international airport and a popular transit hub.
