Based at Aurora
- The Chujiao CJ6-A aircraft was
designed in the late 50's as China's first internally
designed trainer. The design team, lead by Mr. Cheng
Bushi, borrowed some features from the Russian Yak 18A and
relied heavily on pilot input. The aircraft began full
production in 1962 at the Nanchang Aircraft Factory, and
approximately 5,000 have been built for military forces
around the world. The aircraft is still in production.
According to Mr. Bushi the aircraft has never experienced a
structural failure. Hal Morley has taken delivery of a
new CJ built in June, 2001, the first of its kind to be sold
to a civilian.
- The planes are called Yaks in
part because 1) there is a strong family resemblance, 2)
many parts including the engine are interchangeable, 3) it's
a cooler name and 4) most people including ATC don't know
what a Nanchang is while they do have a concept of a Yak.
- The CJ is a pilot's plane is
and is exceptionally responsive and easy to fly with
virtually no bad habits. Many of the owners today are
former military and airline pilots.
- Yak "8" has been
extensively restored and modified for performance, comfort
and looks. Craig Roberts did the paint, Shane Wease
and Bill Tyler handle mechanical things.
- The engine is a Russian
Vedeneyev nine cylinder, air-cooled engine producing 360 hp
at sea level.
- Prop is a 8.5 foot, three
bladed constant speed Whirlwind
- Operating systems including
engine start, brakes, gear and flaps are pneumatic and work
equally well in severe hot or cold environments.
- Engine heat is regulated by a
set of gills or shutters mounted in front of the engine
(same function as cowls). A separate pilot-controlled
door controls air flow over the oil cooler.
- Fuel totaling 74 US gallons is
carried in four wing tanks. At fast cruise of 165 kts
the fuel burn is about 19 gph; at economy cruise of 145 kts
it burns about 13 gph.
- VNE is 210 kts although some
adventuresome pilots have reported upwards of 235 kts.
- Empty weight is 2,400
pounds. Gross weight is 4,000+ pounds.
- Initial climb rate out of
Aurora with full gross on a nice day is more than 2,500 fpm.
Two last points:
- Hal says Evelyn prefers to fly in the
Yak over the Bonanza because "it looks more like it is
supposed to fly and the comfort and visibility are much
better".
- Yak "8" won the
Judge's Choice Award at Oshkosh in 2001.
