Well it looks like Technical Editor Ed Wischmeyer may have splashed around too much! Eds comment on page 12 [of the June 2007 issue] regarding Australias certification of homebuilts is totally incorrect. For the record, Australias amateurbuilt aircraft are covered by the Civil Aviation Safety Authoritys Civil Aviation Orders (CAO) 95.10, CAO 95.32, CAO 95.55 paragraph 1.5; our LSA regulations are included into a revised 95.55 paragraph 1.8 with kitbuilt in paragraph 1.9, CAO 101.55. Amateur building of aircraft in Australia is administratively covered by CAO 100.18 Airworthiness Administration and Procedures-Amateur Built Category Aircraft (see www.casa.gov.au.). Also the U.S. is trailing Australia in certification of ultralights, and our LSA regs off er a lot more design standards and a widerrange of props. Hoping the above helps to provide some facts.

But then I was made even sadder with Marys comment that you probably could build your own, but you might not meet the regulations. You mean, like maybe I could bend my own gear legs, but they might not be straight? Or, maybe I could build my own wings, but they might not be true to the designed airfoil? Mary, this is the sort of inane comment that has turned me and many other builders off to the Elite Aircraft Associations flagship publication. Making things work and meet regulations is what we do. Buying Aerofl ashs overpriced LEDs will not guarantee that they are aligned properly on a crooked wing. If someone has the audacity to align a set of wings properly, why would aligning a few lights of the correct colors prove difficult?
I find the haughty, consumerism attitude exhibited here to be insulting and subversive. Were building airplanes over here, and were doing it well. We don’t need to hear about how some marketing fl ack is puzzled that wed want to do it ourselves, and we don’t want to hear that we might not be able to handle the job. If we just wanted something that was approved and guaranteed to work, wed just buy a Cessna and be done with it.

We feel the same way. Barnaby began a short series on propeller design last month; it continues on Page 68.-Ed.
