So what is a SB.
It's a means of two things.
It's a way of the manufacturer limiting liability if you don't do something as they have asked.
Next it's a way to bring defects that need to be addressed to the market quickly and easily.
In the old days and forget anywhere else in the world but here. They were addressed and if Casa thought they was of merit they were made into a AD. This meant that SB didn't have to be complied with. This option is no longer valid.
The owness is now on the certifying lame. Their is no paper work that an owner can say yes or no and the lame be protected.
Now we have country of origin ADs. If you every won't to see how we become useless go to Casa site. Ads. Equipment. Restraint equipment. 2013-0020R4.
Then tell me and the rest of use how to compily with this AD here in Australia.
