The value of ‘The Case for Pilot Error’ should be rated by the purpose of the report (small print at the end):-
“
The purpose of the report is to help our institutional clients answer the following questions: 1) what are issues, 2) can the problems be fixed, 3) how long will it take, and 4) at what cost. The last step is to value BA (Boeing Co) and the airlines impacted by the grounding of the MAX aircraft fleet.”
Also by who the authors are now, opposed to what they list as piloting experience - ‘what we say reflects thoughts’.
“…
founded AirlineForecasts, LLC … has managed airline and transportation-related investment research … Clients included …, Southwest, and WestJet pilot groups.
And their conclusion:-
“
Examining both accidents separately provides valuable insights—it’s easy to understand how these unrelated airlines and crew may have responded in similar ways—but the overall conclusion in our previous article, “Boeing’s Grounding: Catastrophic Crashes, and Questions About Boeing’s Liability And 737 MAX Aircraft Viability,” still stands—the major contributing factor to these accidents was pilot error.”
Which begs the question what is ‘pilot error’; or of greater concern is if the views of these US based, airline pilots (authors) reflects the standard or effectiveness of human factors training in the wider industry.
