Curious why the crew made such short electric trim inputs. If the nose is heavy stay on the trim until it isn’t.
Also the report says they ran the checklist. I can’t see in the transcript where they did that. They called out 2 steps and turned the switches back on at the top end. That is not part of the checklist.
Boeing has already admitted the MCAS software is flawed but common. As pilots we have to fly airplane. Trim and if that is not enough trim some more. If in goes back down trim again and when it gets to where you like it turn it off. The Lion Air Captain as was mentioned before was flying for a while trimming with no issue. Problem started when the Lion Air FO stopped trimming.
