Brake discs are attached to the wheels with thru-bolts I
or capscrews, and are an integral part of the wheel.
The nose gear is a combination of conventional air/oil
(oleo) strut and fork, incorporating a shimmy dampen-
er. The nose wheel is steerable with the rudder ped-
als up to a maximum pedal deflection, after which it
becomes free-swiveling up to a maximum travel of
30 degrees each side of center. Through use of the
brakes, the aircraft can be pivoted about the outer
wing strut fitting. Nose and main wheel speed fair-
ings are available for installation.
