ROTOR BLADE TIE-DOWN.
CAUTION
Secure the tie-down ropes carefully.
Do not damage the skin by flipping
the strap weights around the
tailboom.
NOTE
Ensure that strap side of main rotor tie-
down boot is on top side of blade and
drain hole is positioned at bottom of
blade.
a. To tie-down the aft blade, securely tie the straps
of the boot to the 1/2 inch polyester rope near the boot.
Ensure the ropes are long enough to cross and tie in
position.
b. The forward blade shall also be tied down using
the same boot strap/rope arrangement device. The
ropes shall be routed between the base and side sup-
port struts of the forward lower cutter and tied at the rear
of the base. In the final tie-position the blades must be
in a level position.
c. Install covers on pitot tube, engine exhaust, and
engine inlets.
d. An alternate method of installing pitot and en-
gine inlet covers will aid in preventing marring and
scratching of windshields and is accomplished as fol-
lows:
(1) Route strap from pitot tube through lower
front edge of pilot door near lower hinge, and then out
the top edge of door to engine air inlets.
(2) Cut strap connecting pitot cover to engine
shields strap at both ends. Pitot tube cover may be held
in place with the nylon cord and/or a scrapped packing
of proper diameter. If a packing is used, it may be perma-
nently attached to pitot tube cover to prevent its loss
when the cover is removed. The strap connecting the
engine shields should also be shortened.
e. Position collective control full down, and tighten
friction.
f. Center cyclic control and tighten friction.
g. Close all windows, doors, and access panels.
h. Fill fuel tank to capacity with prescribed fuel.
i. Secure all ground handling equipment.
