Tim Clark, the president of Emirates, has joined a chorus of airline executives in warning that Boeing is running out of time to restore its reputation following a series of safety and manufacturing blunders.

In an interview with the Financial Times published Sunday, Clark said he had seen a “progressive decline” in Boeing’s standards, which he put down to long-running management and governance missteps, including prioritizing profit over engineering excellence.

“They’ve got to get their manufacturing processes under review so there are no corners cut etc. I’m sure Dave Calhoun and Stan Deal are on that,” he added, referring to Boeing’s CEO and head of commercial airplanes respectively. “This is the last chance saloon.”
