NOSE GEAR
3.0 NOSE GEAR
The nose gear consists of composite fiberglass
beams that are attached at the bottom to blocks
that caster. Inside the block is a castering pin
that is set into the machined fork assembly.
The castering pin allows the nose wheel to
pivot in a complete circle. The 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 the 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
