Boeing's apology for the Ethiopian Airlines crash last month is "too little, too late", the pilot's father has told the BBC, ONA reports.
Dr Getachew Tessema was speaking a day after the US manufacturer admitted for the first time that the plane's anti-stall system was a factor in the crash.
Boeing's chief executive officer also said the company was "sorry for the lives lost".
The Boeing 737 Max crashed just after take-off killing all 157 on board.
A preliminary report from the Ethiopian authorities issued on Thursday said the pilots of flight ET302 "repeatedly" followed procedures recommended by Boeing before the crash south of the capital, Addis Ababa.
The pilots were responding to the plane nose-diving as the anti-stall system malfunctioned.
