Tiga, it is important to get the FULL story before making statements.
It is my understanding from an engineer, that Casa has given the same approval ALSO to the red Rat in the following cases. "Where transit time is less than 4 hours" an engineers signature for a preflight inspection is not required. I further understand that the engineers intend to continue signing the preflight to cover their own butt!!
Yes, I am concerned that the airlines are trying to reduce preflight inspections of aircraft, but it is even more concerning that CASA is approving these moves!!
