Boeing has said told reporters that its embattled 737 Max aircraft will return to the skies before the end of the year.
The jet was grounded after two fatal crashes, including the Lion Air disaster, in which 189 people were killed a year ago.
But just hours after Indonesian investigators blamed mechanical and design problems for the crash, Boeing said it had developed software updates.
It said it was working with regulators to return the jet to service.
“Our top priority remains the safe return to service of the 737 Max, and we’re making steady progress,” Boeing boss Dennis Muilenburg said as the company reported its financial results.
The firm said it had also developed a training update and that it expected regulators to allow the planes to take off again before the beginning of 2020.
“We’ve also taken action to further sharpen our company’s focus on product and services safety, and we continue to deliver on customer commitments and capture new opportunities with our values of safety, quality and integrity always at the forefront,” Mr Muilenburg said.
