which deflects upwards as the load increases. The elastomer pack in the nose gear
compresses as the load increases. In each case, the spring returns to the original position when
the load is removed.
Pushing on both toe-brake pedals applies both disk brakes. The airplane will stop in a straight line.
Pushing on one toe-brake pedal only applies the brake on that side. The airplane will steer to that
side.
Pull the parking brake knob fully aft. Then push on both brake pedals to apply the parking brake.

CHAPTER 32-10
MAIN LANDING GEAR
1. General
This Section gives you the data for the main landing gear. It gives you the trouble-shooting and
maintenance practices. Refer to Chapter 32-40 for data for the main wheels and the brakes.
2. Description and Operation
Each main gear strut is an aluminum alloy leaf spring. Two strong mounts attach each spring to the
spar bridge in the fuselage. Small panels with flexible centers seal the gap where each strut goes
through the fuselage shell.
The inner mount is a large vertical bolt. The bolt goes through a metal block which attaches to a Ushaped
bracket. The bracket goes under and around the spar bridge. Spring washers separate the
top face of the spring from the block. A castle-nut pre-loads the spring washers.
The outer mount is an H-shaped bracket. The top arms of the H go fore and aft of the spar bridge.
The leaf spring goes between the bottom arms of the H. A retaining bar holds the leaf spring in
position. Ultra-high molecular-weight inserts go above and below the leaf spring to prevent chafing
damage. Brass strips go each side of the leaf spring.
Four bolts at the outer end of each strut attach these components:
− An aluminum axle.
− A brake torque-plate.
− A mount for the GFRP wheel fairing (Optional).
When the airplane is on the ground, the inner end of the leaf spring pulls down on the inner
mounting. The outer end pushes up against the outer mounting. When the airplane is flying, the
inner end of the leaf spring pushes up on the inner mounting. And the outer end pulls down against
the retaining bar of the outer mounting.
