Crew didn’t perform part of checklist, person familiar says
New details in the probe into the Ethiopian 737 jetliner crash that indicate the pilots disabled a safety system driving down the nose -- yet still crashed -- only deepen the mystery of what happened, say pilots and former investigators.
The flight crew on the Ethiopian Airlines aircraft followed at least part of a protocol set by planemaker Boeing Co. to manually disable an automated anti-stall system as they tried to save the 737 Max jet, a person familiar with the situation said as Ethiopian authorities prepare to release a preliminary report on the accident Thursday.
