Rules, what rules? The situation in this country is there is a conflict as to which government authority, civil aviation, politur, PN, etc. has license to regulate the aircraft. Is it a plane? An acquaintence of mine flies an ultralight as a business and has been hounded for years by the various government agencies, each saying they have authority over him. In truth they were looking for a commission. He got so frustrated, he was forced to shut down the flying business for a couple of years and focus on another tourist related business. He only reopened the ultralight end recently and I feel he had to pay someone off to do so. If I do see him I'll ask what authority regulates his business this week. My recommendation is don't get into that business here in the D.R. unless you have lots of up front capital, a thick skin, and know somebody in a high place. Regards, PJT
