I have for a few years thought of planning a trip to the USA and flying FAR103 ultralights preferably a Lazair as i own one here in Australia. I asked the EAA and they say no problem same with the FAA, i spoke to them at last years Airventure.
Now i have a person here in OZ that insists i should get the same Homeland Security clearance that a GA pilot or student or LSA pilot requires before they can undertake any flight or instruction. I believe that all i require is the usual security check (ESTA) that is to be obtained before arriving in the USA.
Who would i need to ask? Could someone please point me in the right direction. The Homeland Security web site is a bit vague for an inquiry of this type.
I'm really itching to fly Dale's E Lazair next year

Thanks in advance
Ozzie
