Ethiopian Airlines flight ET 302 had flight control problems’ before it went down, the company’s chief executive, Tewolde GebreMariam has said.
He made the disclosure while speaking with Richard Quest of CNN on Tuesday.
GebreMariam said a recorded conversation with air traffic control detailed final moments of the flight.
“He was having difficulties with the flight control of the airplane, so he asked to return back to base,” he said.
On Sunday, a Boeing 737 MAX 8 operated by Ethiopia Airlines crashed en route to Nairobi from Addis Ababa, killing all 157 persons on board.
He said the airline’s pilots had received additional training on the flight procedures involving the 737 MA after the Lion Air crash.
“We don’t yet know the exact cause of the accident, and speculation is not helpful in either way but I think there are questions without answers on the airplane” he added.
