3.0 NOSE GEAR
The nose gear consists of composite fiberglass
beams that are attached on top to a moving
carriage and on the bottom to blocks that caster.
Inside the block is a castoring pin that is set into
the machined fork assembly; the castoring pin
allows the nose wheel to pivot 360 degrees.
Geometry is such that no shimmy dampers are
necessary.
The nose gear has an over-center down lock.
Retraction occurs when pressure is applied to
the forward face of the actuator piston and the
carriage is drawn along the tracks in the nose
box. Gear position light proximity switches are
closed when the piston (containing magnetic
material) has reached either end of its travel.
Refer to Figure 3.1 for visual reference
The nose gear has single 5:00 x 5 10-ply tire.
All tires must be approved to TSO C62, type III.
