Will you elaborate? “A requirement for MCAS was identified. It was then added.” What is not included in the statement is:
“It was then certified to the C of A....” How? By Boeing memo? Or did it just sound like a good idea?
In the AD, “After manufacturer’s research, it was ‘discovered’ (sic) that Trim could continue Nose Down after receiving sensor data related to a high and erroneous AoA value...” Can we review the research? Because I am not buying that it was ever “unknown”.
