Grand Jury Eh?
[Comments enabled]

It's about damned time.

A report broke Friday that the unions representing American, United and Southwest pilots have all been hit with subpoenas from the criminal division of the US Department of Justice, requiring them to turn over 737 Max-related documents to a federal grand jury, according to Bloomberg. 

The unions confirmed for me Saturday that they'd been served. 


There are several reasons for a criminal investigation here.  First and foremost is what appears to be a deliberate attempt to mislead the FAA in that during flight testing the limit of authority for MCAS was quadrupled yet the FAA was not notified of this, nor was the fault analysis re-run and re-submitted despite testing disclosing that the original design for the system was off in its required limit of authority by a factor of four.

Then there is the apparent change in the stabilizer trim disconnect switch operation; the previous generations of the 737 all separated the disconnection of flight control computers and the "master" disconnect, which would also disable the manual trim switches on the control yoke.  The capability to deny automatic trim input separately from the master disconnect appears to have been removed from the MAX yet that appears to not be clearly disclosed in pilot training or system documentation differences.  The reason for that may have been to evade a type certificate difference but irrespective of the reason that's #2.

Next up, and perhaps the most damning, is that apparently Boeing had reports on failures of the sensors involved for months before the first crash along with knowledge that the system had failed to alert on same and did not initiate the process leading to an AD to correct it prior to the crashes.

Does any of this lead to criminal liability?  In my opinion if the facts bear out what appears to be the case it damn well should.
