Ethiopian Airlines stated the crew had been trained on the MCAS after the Lion Air crash. However, the crew did not follow proper procedures to place the stab trim switches in cutout. Manual trim was unusable because they left the power levers at TO power and exceeded VNE. The high speed caused high aerodynamic loads on the stabilizer, making manual trim impossible.
Here we go again. It was the plane/it was the pilots, ad infinitum.
