PARIS—Europe’s air safety watchdog has no firm date for Boeing’s grounded 737 MAX to resume flights, it said on Tuesday, adding that the U.S. planemaker had some more work to do before a 17-month-old safety ban could be lifted in Europe.
The U.S. Federal Aviation Administration on Monday issued a proposed directive requiring four design or operating changes in the wake of two fatal 737 MAX crashes, in a move which could lead to the agency lifting a grounding order on the jet later this year.
