Gengis,
It even more frightening !!
In the simple days we had FAA AD's for US built aircraft.
(apart from US lawyers legalistic jargon
) realtively easy.
Now for the same aircraft now we have FAA AD's to comply with, plus UK CAA mandatory SB's AND EASA AD's.
We have now found some of them have slipped through the cracks !
I guess they have to change a working system to make more money !
