Landing Gear

Main Gear

The main landing gear are bolted to composite wing structure between
the wing spar and shear web. The landing gear struts are constructed
of composite material for fatigue resistance. The composite
construction is both rugged and maintenance free. The main wheels
and wheel pants are bolted to the struts. Each main gear wheel has a
15 x 6.00 x 6 tire with inner-tube installed. Standard wheel pants are
easily removable to provide access to tires and brakes. Access plugs
in the wheel pants can be removed to allow tire inflation and pressure
checking. Each main gear wheel is equipped with an independent,
hydraulically operated single cylinder, dual piston, disc brake.

Nose Gear

Serials 0002 thru 2437:
The nose gear strut is of tubular steel construction and is attached to
the steel engine mount structure. The nose wheel is free castering and
can turn through an arc of approximately, Serials 0002 thru 1885, 216
degrees (108 degrees either side of center) or, Serials 1886 and subs,
170 degrees (85 degrees either side of center). Nose gear shock
absorption is provided by polymer shock absorbing pucks. Steering is
accomplished by differential application of individual main gear brakes.
The tube-type nosewheel tire measures 5.00 x 5.
Serials 2438 & subs:
The nose gear strut is of tubular steel construction and is attached to
the steel engine mount structure. The nose wheel is free castering and
can turn through an arc of approximately 170 degrees (85 degrees
either side of center). Nose gear shock absorption is accomplished by
an oleo strut. Steering is accomplished by differential application of
individual main gear brakes. The tube-type nosewheel tire measures
5.00 x 5.

Brake System

The main wheels have hydraulically operated, single-disc type brakes,
individually activated by floor mounted toe pedals at both pilot stations.
A parking brake mechanism holds induced hydraulic pressure on the
disc brakes for parking. The brake system consists of a master
cylinder for each rudder pedal, a hydraulic fluid reservoir, a parking
brake valve, a single disc brake assembly on each main landing gear
