For once CASA are doing the right thing. There's obviously a problem with this version of the old 737 & perhaps the less trained/experienced drivers are unable to handle the fault when it occurs?
Airbus have had their fair share of similar issues so will be interesting to see how Boeing get out of this one unscathed cause Airbus sure has coped a lot of flak over the years!
RIP to the many that lost their lives in such a dreadful tragedy:-(
