ADDIS ABABA, Ethiopia — Ethiopian Airlines surpassed many carriers by becoming one of the first to install a simulator to teach pilots how to fly the new Boeing 737 Max 8, but the captain of the doomed Flight 302 never trained on the simulator, according to people close to the airline’s operations.

The people, who spoke on condition of anonymity because Ethiopian Airlines had not authorized disclosure of the information, said the carrier had the Max 8 simulator up and running in January, two months before Flight 302 crashed.

Boeing has said that experienced 737 pilots needed little training for the new Max 8, an assertion that has now come under close scrutiny by regulatory officials and pilots at other airlines. Two of the planes have fatally crashed in the past five months, and regulators around the world grounded all Max 8s last week.

The pilot of Flight 302, Yared Getachew, who had 8,000 hours of flying experience including on the 737, took a refresher course on a different simulator in late September and early October, according to one person familiar with the airline, and was not due for another round of simulator training until after the crash on March 10.
