Boeing Says 737 MAX Software Update Complete

Boeing said Thursday that it completed its software update on the 737 MAX after two deadly crashes resulted in a global grounding of the aircraft.

The proposed fix, which addresses a problem with a flight handling system thought to be a factor in both crashes, must now win approval from US and international regulators before the planes can return to service.

US airlines have targeted August as the date they expect to resume flying on the 737 MAX.

But Boeing's announcement - which lifted shares of the embattled company - comes only a week before the US Federal Aviation Administration is set to brief its international peers among civil aviation regulators on its process for allowing the planes to fly again.
