Manual moving:
Excessive lead − lag load applied to the main rotor blades during
ground handling can result in damage to the elastomeric damper
buns and failure of the damper assembly. Operators should use
extra caution to avoid lead − lag loads in excess of 35 pounds at
the tip of the main rotor blades.
Ensure all stress panels are installed on helicopter before moving.
Attach ground handling wheels (Ref. Figure 7−2) and hold tail up while low-
ering the wheels (raising helicopter).
Manually move helicopter on ground handling wheels by balancing at tail-
boom and pushing on rear fuselage portion of air frame.
Towing:
Tow helicopter on ground handling wheels by attaching suitable tow bar to
tow bar fittings. If tow bar is not equipped to keep front ends of skid tubes
from dragging, have an assistant balance helicopter at tailboom.
Ensure all stress panels are installed on helicopter before moving.
Except under extreme emergency conditions, do not tow helicopter
at speeds over 5 mph. Do not allow front end of skid tubes to drag
on ground. Avoid sudden stops and starts and short turns which
could cause helicopter to turn over. Allow inside wheel to turn (not
pivot) while helicopter is being turned. Safe minimum turning ra-
dius is approximately 20 feet.
