to extinguish the fire.
Apply external electrical and hydraulic power (if available)
and continue with a normal shutdown. If external
electrical and hydraulic power is not available, proceed
as follows:
1. No. 2 Engine — Perform a normal shutdown.
2. All unnecessary electrical switches
(except BATT switch) — OFF.
3. GEN 1 and 2 switches — OFF.
4. ENG COND 1 lever — GND. Wait until PTIT
decreases and then begins to increase; then
move the ENG COND 1 lever to STOP.
5. ENG 1 START switch — MTR until rotors stop
or PTIT is below 260
C.
6. Normal shutdown — Perform.
9-1-29. Engine Oil — Low Quantity/High Temperature
or Low Pressure.
A low engine oil quantity condition will be indicated by the
lighting of the NO. 1 ENG OIL LOW or NO. 2 ENG OIL
LOW caution light. When either oneor both of these caution
lights come on, about 2 quarts of usable oil remain
in the respective oil tank. If one or both of the caution
lights come on, check oil temperature and oil pressure
indicators (affected engine) for abnormal indications. If
the indication on the oil temperature indicator is high or
the indication on the oil pressure indicator exceeds limits,
high or low, perform the following:
1. If engine power is required for flight:
Land as soon as possible.
2. If engine power is NOT required for flight:
a. EMER ENGINE SHUTDOWN —
Affected Engine)
b. Land as soon as practicable.
9-1-30. Engine Chip Detector Caution Light ON.
If either NO. 1 or NO. 2 ENG CHIP DET caution light
comes on, perform the following:
1. If engine power is required for flight:
Land as soon as possible.
2. If engine power is NOT required for flight:
a. EMER ENGINE SHUTDOWN — (Affected
Engine)
b. Land as soon as practicable.
9-1-31. Rotor, Transmission, and Drive Systems.
WARNING
If an interposer block or rotor blade droop
stop is not in place, the flight engineer will
notify the pilot in command. All non-crewmembers
will evacuate the aircraft to a safe
position. If possible, crew will contact maintenance
and attempt to engage interposer
block with a high pressure water stream or
prepare aircraft for shutdown in such a way
as to minimize damage to the aircraft and
components and prevent injury to personnel.
If interposer blocks appear to be in place,
the flight engineer will clear the pilot to shut
down the first engine. After the first engine is
shut down, the flight engineer will observe
the rotor blade 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 engine condition lever
(ECL) should be advanced until sufficient
rotor RPM is achieved to lift rotor blades off
of droop stops to insure no blade contact
with airframe and maintenance contacted to
prepare aircraft for an emergency shutdown
that will minimize damage to aircraft and
injury to personnel.
9-1-32. NO. 1 or NO. 2 ENG XMSN HOT Caution.
1. EMERG ENG SHUTDOWN.
F 2. Affected engine transmission — Check.
3. Land as soon as possible.
9-1-33. Transmission Debris Screen Latches.
Trouble developing any of the five transmissions may be
indicated by a tripped latch indicator. This information will
be presented on the flight engineer’s MAINTENANCE
PANEL but will not be shown in the cockpit. If a latch
indicator trips, it may be reset once during the flight. If an
indicator trips:
FWD, COMB, or AFT DEBRIS SCREEN indicator:
F RESET/GND/TEST switch — RESET.
If indicator does not reset:
Land as soon as possible.
LEFT or RIGHT DEBRIS SCREEN indicator:
F RESET/GND/TEST switch — RESET.
TM 1-1520-240-10
9-1-21
If indicator does not reset and engine power is required
then:
Land as soon as possible.
If indicator does not reset and engine power is required
then:
1. EMERG ENG SHUTDOWN.
2. Land as soon as practicable.
9-1-34. Transmission Low Oil Pressure or High
Temperature Indications.
Developing trouble in the transmissions can be identified
by high oil temperature or low oil pressure, as indicated
by transmission temperature and pressure indicators
and cautions. If an abnormal temperature or pressure
indication develops, closely monitor the caution capsules.
The XMSN OIL PRESS (main or aux) and XMSN OIL
HOT caution capsules operate independently of the
pressure and temperature indicating system and come
on when a low pressure or high temperature condition
