M,,·17·1B. Flight manual
engine operational parameters occurs, abort the mis-
sion, shut the engine down manually and proceed ac-
cording to ML-l-17-1B Flight Manual.
6.6. Abnormal vibration of engine
(1) Indications
(a) Illumination of the amber annunciators.
(b) Illumination of the red annunciators.
(2) Crew's actions
(a) Upon illumination of the amber annunciators increase alertness in
monitoring operation of the engines and continue fulfilment of the
mission.
(b) Upon illumination of the red annunciators reduce the engine power
setting by means of the collective pitch control lever in order to re-
duce the vibration magnitude. If the red annunciator goes out abort
the mission, establish an airspeed of 130 to 140 km/h, and proceed
to the nearest aerodrome. Execute running landing.
If the red annunciator fails to go out shut down the engine affected
by abnormal vibration and proceed in accordance with the instruc-
tion for actions required at one engine failure.
6.7 Low engine oil pressure. Illumination of the L ENG (R ENG) LOW POlL annuncia-
tor.
(1) Indications
(a) Flashing or steady illumination of the L ENG LOW OIL PRESSURE
or R ENG LOW POlL amber annunciators.
(2) Crew's actions:
(a) If the parameters are normal, continue performing the mission, in-
crease alertness in monitoring engine oil pressure and temperature.
If the engine oil pressure is decreased by 2 kgf/cm
2
proceed as fol-
lows:
(b) Operate the respective throttle lever to reduce the affected engine
poWer setting· to a niininillnialioWing· continuation of
f1i~ht,
and
make sure the engine oil temperature does not exceed 150 C.
Abort the mission and proceed to the nearest aerodrome.
Execute running landing. Should the engine oil pressure drop below
2 kgf/cm
2
shut down the engine and proceed in accordance with the
instructions required for actions with one engine failed.
6.7A. Illumination of the CHIPS IN L ENG or CHIPS IN R ENG (for helicopters the
engine oil system of which is equipped with CC-78 chip detector).
(1) Indications:
(a) Flashing or steady illumination of the CHIPS IN L ENG or CHIPS
IN R ENG amber annunciators.
(2) Pilot's actions:
(a) Monitor the engine oil pressure and temperature.
(b) If the engine parameters are normal, abort the mission, increase
alertness in monitoring engine oil pressure and temperature and
land on the nearest aerodrome (.selected ground).
