That has not been determined to have been an engineering defect.
Fun fact: Neither of the 737 Max 8 MCAS crashes were determined to be an engineering defect either.
Neither of those were caused by moving both fuel control switches to “off” during takeoff.
The official cause of the Lionair 610 crash was literally "The pilot pushed the nose down for no reason in the middle of the flight"
