"We are still waiting for Boeing to formally submit the software for approval," he said on the sidelines of a summit of global aviation regulators in Fort Worth, Texas. Elwell said the FAA sent Boeing additional questions about its proposed fixes for the MAX planes, which caused the delay. The regulator called the summit to walk through the steps taken to address concerns with the MAX aircraft after it was criticized for dragging its feet on ordering the jets grounded. Two American carriers -- Southwest and American -- have announced plans to restart flights on their MAX aircraft from August in hopes the fix will be completed by then. The FAA chief added that he couldn't say when the jet would be back in the air, blaming the recent delay.
