They have dissected the more than 300 pages of the Indonesian National Transportation Safety Committee (NTSC) final report on Lion Air Flight 610 and John and Greg reach a very different conclusion. The Maneuvering Characteristics Augmentation System (MCAS) was not the root cause, flight crew deficiencies are more likely the root cause.
Once again, John and Greg stick to the facts presented in the report. They find that those facts are twisted in the report analysis as well as media coverage. This leads to misplaced blame on the MCAS system and, worse, missed opportunities to improve aviation safety.
Calling the conclusion that MCAS was the cause a “leap of logic,” John and Greg instead look at documented issues with crew training and the direct parallels those issues have to what happened in the cockpit that fateful day.
