You'll be singing a different tune if you were flying the affected aircraft. If it was never a threat to safety,do you think Dassault would request the EAD?
"This condition, if occurring again, could lead to loss of control of the aeroplane"
I would be singing exactly the same tune.
Yes there is a problem and Dassault is working on solving, and they asked to ground the aircraft till they solve it.
But is not that the 7x suddenly became a killer aircraft.
We are talking about a ferry flight, with the pilots aware of the fact that they have to keep an extra eye to what the aircraft is doing. The problem with the aircraft in Malaysia is that what happened, happened suddenly, unexpected, and this can lead to loss of control on any aircraft(and it did happen)
If you are ferrying an aircraft that you know that a similar problem could happen you would be extra careful and watching the trim closely.
No need to put your soul in the hands of your god and say your prayers that hopefully everything goes well.
