RE: SEMPRA Members
Randy,
I don't know the procedures for SEMPRA. However, I would think that all it would take is some discussion amoung the group. Here in the CAPS we had the FAB 5 which consisted of 5 members who would decide on such things. AND for sure there is absolutely no reason why you can't re-instate the 16500 rule at the local level. If this will increase participation, more power to you guys.
As far as the proposal process for the AMA, there is a section titled intent. This intent needs to be defined, and is filled out by the proposer.
In regards to the intent of the 428 weight increase... I don't recall the exact wording, but I remember it to be along the lines of updating the rules to be more consistant with 422, which is 50 square inches smaller and .5 lb heavier. The logic was that the same equipment is being used for both events and the airframes are smaller but can weigh more.
