"Building the bird"called a Cozy ZU CZZ, Serial No 219.

Promoting homebuilding in South Africa.

Contact Gavin Lawson  if you are a homebuilder and require parts made.

The Cozy Mk4 owner Chris van Hoof decided to build this composite (fibreglass) airplane from plans he bought in 1994. It has a 4 cylinder  200hp Lycoming engine. It is a "pusher" (engine at the back) with a canard wing in the front. The front wheel is retractable. The canopy opens sideways. It seats 4 adults. Nat Puffer designed this plane in the 1970's and it still looks futuristic.

Burt Rutan's the designer of the Longeze  (2 seater in tandum) and others, became the first airplane to fly into space and back. Mike Melville (South African living in the USA) piloted the plane on 21 June 2004, to 100km above the earth.

The engine had been giving lowish oil pressures since its maiden flight, so Chris decided to take out the engine and do an inspection. As the engine was out it was an opportunity to check everything. We stripped it right down and it all looked good for the 35 hours of flight. A new oil pump is being fitted, and the usual honing of the cylinders, new rings and bearings will be installed and re-assembled. A couple of new instruments will be installed at this convenient time as well.

Note the late winter afternoon smog and the dry highveld grass.

09/09/2005 The Cozy "fledged" on its maiden flight today. Chris van Hoof the (owner builder) and Dave King the test pilot, flew a test circuit of 15 minutes at Baragwanath airport (Johannesburg). It handled well in good flying conditions.
This is the first 4 seater Cozy built and flown on the African continent, a proud achievement and occasion for a number of people. There is still a lot of testing to do, and then the finishing and detailing.
Well done to everyone concerned.
