7–4. LANDING GEAR
The landing gear (Ref. Figure 7−3) supports the helicopter when it is in contact
with the ground. The landing gear can withstand loads encountered during landing,
ground handling, and provides a stable platform to prevent ground resonance.
The landing gear primarily absorbs normal landing forces, with the capabilities
to absorb severe landing forces during overload conditions. The landing gear dimen
sions are based on the required minimum roll−over and minimum pitch−over angles.
A minimum angle of 27 degrees is maintained from the center of gravity (CG) location
to the skid−to−ground contact point. The landing gear consists of the following compo
nents:
Forward and Aft Crosstubes − Provide energy absorbing capabilities during nor
mal or severe landings.
Forward and Aft Saddle Assemblies − Provide a means to attach the crosstube
assemblies to the fuselage attachment points.
Side Stop Clamp Assemblies − Prevent side movement of the crosstube assemblies.
Forward Spacer Fittings − Forward attachments for the skid tubes and forward
crosstube assembly.
Skid Tubes − Provide landing gear−to−ground contact points.
Damper Assemblies − Aft attachments for the skid tubes and aft crosstube assem
bly.
Each damper has a reservoir fluid level indicator that is a rotating shaft which
shows through a 120
pie shaped window. When the reservoir is filled, the window
shows green with a very thin wedge of red showing to the first notch on the
housing. The thin wedge of red shows the reservoir is not completely full, to
allow for fluid expansion.
Ensure fluid level in reservoir is within limits.
Reservoir is near empty, when the window shows red and should be serviced
(RMM. Section 12−00−00).
