The propeller broke, severing the adjoining propeller and the turbine fell aside, in keeping with preliminary investigations.
In a digital press convention, Sumwalt reported that the cracked propeller was transported in a non-public airplane to Pratt & Whitney headquarters for examination by specialists from the transportation board.
“Our mission is to grasp not solely what occurred however why it occurred in order to stop it from taking place in the long run,” Sumwalt stated.
