The 429s flying at increased gross weight are not flying under FAA or EASA jurisdiction.
Matter of fact, when Bell asked the FAA to increase the gross weight they were given a virtual bucket and shovel and told to head for the beach.
Russia, Brazil, India China, Pakistan, Canada (guess is where they manufacture the 429, hint hint), have their own certification "standards".
They can only hope to motivate the officials to increase Pt.27 limits....
It has been done before...
If more money needs to be invested in the right environment and that money can bring more sales, then it's a good investment...
