2-83. GROUND HANDLING.
Towing. Tow rings are provided on forward inboard
portion of each landing gear skid (figure 2-24) for attach-
ment of a standard aircraft tow bar. Helicopter is towed
on ground handling wheel assemblies mounted on the
landing skids.
2-84. PARKING.
a. Retract ground handling wheels and allow heli-
copter to rest on skid type landing gear.
b. Install main rotor blade tie-down (figure 2-24).
c. Install engine air inlet shield assemblies in en-
gine inlets and covers on engine exhausts.
2-85. COVERS.
a. Engine Inlet and Pitot Tube. An engine inlet
and pitot cover (figure 2-24) is provided to prevent en-
trance of dust etc., into engine inlet and pitot system
when helicopter is parked. When stowed in helicopter,
stow engine inlet shields and pitot covers securely in
helicopter cabin only.
b. Engine Exhaust. Individual covers (figure 2-24)
are provided for exhaust stacks to prevent entrance of
foreign objects into engine exhaust when helicopter is
parked. When stowed in helicopter, stow engine ex-
haust covers securely in helicopter cabin only.
c. Main Rotor Tie-Down.
NOTE
Ensure strap side of main rotor tie-down
boot is on top side of blade and drain
hole is positioned at bottom of blade.
A rotor tie-down (figure 2-24) is provided for use in moor-
ing the aft main rotor blade. The tie-down prevents the
rotor from see-sawing when the helicopter is parked.
When stowed in helicopter, stow rotor tie-down securely
in helicopter cabin only.
2-86. MOORING.
CAUTION
Structural damage can occur from
flying objects during high wind
conditions. Helicopter should be
hangared or evacuated to a safe
weather area when wind conditions
above 50 knots are expected.
CAUTION
The mooring hardware is to be
carried in the flyaway kit. Flying the
OH-58 with mooring hardware
installed may result in damage to
aircraft’s honeycomb surface. Retain
all installation hardware together for
each separate OH-58A/C helicopters;
due to wear, the bushings may not be
interchangeable. For additional
information, refer to TM
1-1500-250-23-1.
a. If a paved ramp with suitable tie-down rings is
available, positon the aircraft on the mooring pad with
the longitudinal centerline of the aircraft directly above
and parallel to longitudinal axis of pad as shown in figure
2-25. The forward mooring rings are to be located 5 feet
4 inches aft of first mooring point as shown.
NOTE
It will be necessary to attach a mooring
clevis to each of the three jack/mooring
points. The clevis provided with the air-
craft will not be large enough to accept
the hooks on the mooring chains pro-
vided with mooring pad. Mooring rings
are to be installed on aircraft as shown
in figure 2-25.
b. Place the hook-ends of mooring chains into the
appropriate clevis rings. Adjust the chains using the
adjusting devices provided on the mooring pad. Chains
should be adjusted to a point where the slack has been
removed.
c. If suitable spaced ramp tie-downs are not avail-
able, park the helicopter on an unpaved parking area
headed in the direction from which the highest forecast
winds are expected and retract ground handling wheels.
Use mooring anchors to make “dead man” anchors.
Moor helicopter as described in step a.
