I'm new to Experimental and to the Exhibition category in particular. I'm thinking of purchasing a Scottish Aviation Bulldog but I'm concerned about Program Letter restrictions. My mission objective is to attend a few Fly In's, do some recreational low key aerobatics (loops, cubans, etc), carry friends for sightseeing and aerobatics. I've read FAA Order 8130.2 but need wisdom. Should the Program Letter specify the requirements for carrying passengers e.g. to exhibit aircraft performance including aerobatics ... or ... since it does not appear to be prohibited (except in association with flight tests) is it best left unmentioned because it is NOT prohibited? What do y'all do out there regarding pax and aerobatics and the Program Letter? Can I complete a Program Letter with my FSDO prior to purchase to ensure they won't lay down draconian requirements before I have parted with money buying the aircraft? Any help welcome.
