Boeing’s latest version of the 737 Max jetliner made its first test flight on Friday, taking off near Seattle for an expected two-hour trip that the company hopes will signal improving fortunes for its most important plane.
The Max 10 is a slightly larger version of Max jets that are already flying. It is designed to seat up to 230 passengers and compete with the A321neo from European rival Airbus.
Chicago-based Boeing expects to begin delivering Max 10s to airlines in 2023.
Max jets get better fuel mileage than previous versions of Boeing’s venerable 737. Airlines began using the plane in 2017, but Max 8 and Max 9 planes were grounded worldwide for nearly two years after crashes in October 2018 and March 2019 killed a total of 346 people.
US regulators cleared the way for Max jets to resume flying late last year after Boeing made changes, including overhauling flight-control software that played a role in the crashes.
This spring, about 100 new Max jets were idled for several weeks because of an unrelated problem with electrical grounding of cockpit instruments.
The grounding of Max jets and reduced demand for planes because of the pandemic pushed Boeing Co to an 8.4 billion dollars loss last year.
