Boeing says it is working to rebuild trust in its brand, even as it struggles to bring its 737 Max back into service.

The plane was involved in two crashes that resulted in the deaths of 346 people. It was grounded in March and the company has since been struggling to lift the ban. It said it aims to have it lifted by mid-2020, after endorsing simulator training for pilots before flights resume.

David Calhoun, who took over as president and chief executive from Dennis Muilenburg, said he took up the position at a crucial time for the company.

“Working together, we will strengthen our safety culture, improve transparency and rebuild trust with our customers, regulators, suppliers and the flying public. With the strength of our team, I’m confident in the future of Boeing, including the 737 Max”, Calhoun said, adding that the resumption of 737 Max into service being the primary focus.

The company failed to book any new orders in January. “Many of our stakeholders are rightly disappointed in us, and it’s our job to repair these vital relationships”, Calhoun said.
