I believe it is going up to 2910Kg. It will require a software upgrade, by all accounts the transmission and engines are up to it; not much else needed apart from the all the relevant paperwork.
How do ppruner's feel about ECD deleting the 50 and 100Hr servicing on the 135? There is a possibility that the 400Hr will be considerably reduced as well
Now wether the new servicing schedule will apply to the increased MAUW 135 I do not know, but in principle increasing the MAUW / power output of the engines and decreasing the servicing doesn't sound like a good idea to me
