Boeing's first-quarter results addressed the current situation of the 737 MAX while postponing guidance to "a future date," as a significant portion of the manufacturer's commercial aircraft backlog hangs in the balance. GettyBoeing said it is "making steady progress on the path to final certification" for its 737 MAX software update. The FAA's preliminary operational sustainability report, based on Boeing's technical guidance, suggested that the 737 MAX software patch would not require simulator training. It's difficult to overstate the importance for Boeing of ensuring that the 737 MAX takes off again. A total of 4,625 of those 5,600 aircraft on the backlog are Boeing 737 MAX, according to the company's order summary through March of this year.
