ADDIS ABABA, Ethiopia — A preliminary report on a March 10 Ethiopian Airlines crash that killed 157 people will be made public soon, but it may take months to finish the final report, a spokesman for the country’s transport ministry said.

“A date has not been set but it will be released later this week,” Mussie Yiheyis told The Associated Press Tuesday, adding that a high-ranking government official will announce the preliminary result.

“The U.S. National Transportation Safety Board, France’s BEA and an Ethiopian Transport Ministry department have been conducting the investigation,” he said. “It has been conducted as per International Civil Aviation Organization rules and regulations.”

On Monday, Ethiopian Airlines’ CEO Tewolde Gebremariam said the pilots who flew the plane that crashed on the outskirts of the capital, Addis Ababa, had trained on “all appropriate simulators,” rejecting reports that they had not been adequately prepared to handle the new aircraft.
