WARNING
Personnel injury or death may occur and
damage to the airframe and rotor system
will occur if the forward or aft rotor head
rotor blade droop stop(s) on the aft rotor
head are not engaged. After engine run-up
and before flight, or shut down if flight is
not conducted, the flight engineer will
scan the ground in the immediate area of
the aircraft for evidence of detached droop
stops. Prior to moving Engine Condition
Levers (ECL) from ground to stop, flight
engineer will, to the best extent possible,
determine if the interposer blocks on the
aft rotor head are in position and that all
forward and aft droop stops are attached.
If an interposer block or droop stop are not
in place, the flight engineer will notify the
pilot in command. All non essential per-
sonnel will evacuate the aircraft to a safe
location. If possible, crew will contact
maintenance and attempt to engage inter-
poser block with high pressure stream or
prepare aircraft for shutdown in such a
way as to minimize damage to aircraft and
components and prevent injury to person-
nel. If interposer blocks appear to be in
place and no droop stops are missing, the
flight engineer will clear the pilot to shut-
down the first engine. After the first engine
is shut down, the flight engineer will ob-
serve the rotor tip path of the forward and
aft rotor heads. A rotor blade drooping
significantly lower than the other blades
indicates a missing droop stop. In this
case the remaining running engines ECL
should be advanced until sufficient rotor
RPM is achieved to lift rotor blades off the
stops to insure no blade contact with
airframe and maintenance is contacted to
prepare aircraft for an emergency shut-
down that will minimize damage to the
aircraft and injury to the personnel.
NOTE
Aft landing gear ground proximity switches
are not actuated during a water landing.
Therefore, longitudinal cyclic pitch actuators
must be manually set to ground position prior
to engine shutdown on the water.

If DECU display is other than 88, refer to the
DECU BIT Fault Code List/Matrix.

b. FUEL PUMP switches OFF.
c. REFUEL STA switch As required.
WARNING

NOTE
Monitor temperatures during shutdown. If
temperatures rise above 350_C, motor en-
gine immediately until temperature de-
creases below 260_C. Both engines cannot
be motored at the same time.
