The consensus is that these pilots were not adequately trained or knowledgeable about the aircraft, which may of course be true.
But to get into their situation there had to be a failure in the aircraft systems of some kind.
So accepting that the fact that all the US pilots were better equipped to deal with this situation , have there not been any failures of this system on US registered aircraft?
Apart from the 2 we know about, have there not been no log book write ups for this system in the US ?
I donīt know if this incident is related to the discussion. In this case the ADIRU has been replaced.
A Sunwing Airlines Boeing 737 MAX 8, registration C-GMXB performing flight WG-439 from Punta Cana (Dominican Republic) to Toronto,ON (Canada) with 176 passengers and 6 crew, was enroute at FL350 about 50nm northwest of Washington Dulles Airport,DC (USA) when the captain's instruments began to show erroneous indications. The first officer was handed control of the aircraft as his instruments and the standby instruments remained in agreement. The crew decided to descend out of IMC into VMC as a precaution and descended the aircraft to FL250. Descending through FL280 the weather radar and TCAS failed. The crew declared PAN and worked the related checklists. The left IRS fault light illuminated. The flight continued to Toronto for a safe landing without further incident.
The Canadian TSB reported the left ADIRU was replaced.
