It certainly falls withing the mandate to get rid of GA.
As an AOC holder with the 14 seat C208B caravan on it, I think it would indeed impact quite heavily on my operation, if suddenly I have to reduce pax from 13 to 9 and then add an extra $23K worth of equipment.
I guess I will have to remove my thumb and have a look at the NPRM and see in what context it is being proposed, or if they are making any exemptions.
