Approach Idle System Failure AFM 3-08-20
1. Illumination of amber "ENG IDLE" light:
In Flight:
A. If flaps are less than 39°, minimum idle for corresponding
engine may increase to 67% HP RPM.
B. If flaps are at 39°, the flight crew must manually maintain
minimum engine RPM to 67% HP RPM on approach.
On Ground:
A. Minimum idle for the corresponding engine may increase to
67% HP RPM.
2. Approach Idle System Failure - Amber "ENG IDLE" light does not
illuminate:
In Flight:
A. If flaps are at 39°, the flight crew must manually maintain
minimum engine RPM to 67% HP RPM on approach.

Engine Vibration AFM 3-08-30
If EVM exceeds 0.60 LP and/or 0.60 HP:
1. Power Lever .....................................................................................
................ RETARD UNTIL EVM RETURNS TO NORMAL LEVEL
CAUTION: EVM INDICATIONS ALONE SHOULD NOT BE USED AS
CRITERIA FOR ENGINE SHUTDOWN. IN ICING CONDITIONS,
VIBRATIONS MAY EXCEED THE ALERT LEVEL WITHOUT OTHER
ABNORMAL INDICATIONS AND ARE CONSIDERED NORMAL.
If vibration is accompanied by other failure indication:
2. Affected Engine .........................................................SHUT DOWN
If in flight, see Engine Failure / Shutdown In Flight, page EC-6.
If on ground, see Shutdown, page NF-1.

Ice Shedding Procedure AFM 3-08-40
In Flight:
To assist in shedding ice, if high vibration occurs and operational circumstances
permit, one engine at a time may be retarded to idle, held
there for five (5) seconds, and then accelerated to 85% LP RPM. The
power lever may then be returned to its original position.
On Ground:
When taxiing or holding on the ground at low power in temperatures
less than 1°C, engine operation at 85% LP for one (1) minute is
recommended just prior to takeoff and at intervals of not more than
sixty (60) minutes under these temperature and moisture conditions.
This is dependent on taxiway and/or runway conditions and proximity
to other airplanes.

Engine Failure To Start AFM 3-11-10
Failure of engine to start or reach idling speed may be caused by:
1. No engine rotation.
2. No fuel or no ignition of fuel.
Failure of the engine to rotate can be the result of electrical or
pneumatic malfunctions. Check the engine instruments display for the
Start Valve Open (SVO) mnemonic. If not present, see Start Valve
Failure, page EC-17.
NOTE: For airplanes SN 1144 and subs. and SN 1000 thru 1143 with ASC
151, engine failure to start may be the result of a failed igniter. Check EICAS
for IGN mnemonic. If not present, the start may be salvaged by selecting Air
Start Ignition - ON prior to moving the HP cock from OFF to OPEN.
NOTE: Check for fuel flow / pressure to engine. If there is no fuel flow /
pressure verify Fire Handle is FULLY IN.
Auto ignition should occur when the ENGINE START switch is
depressed and its availability will be indicated by the Ignition (IGN)
mnemonic on the engine instruments display. If auto ignition is not
indicated, check for proper selection of the START switch instead of
the CRANK switch. If the CRANK switch has been inadvertently
selected, the start may be salvaged by selecting the proper AIR
START IGNITION switch to ON; or the start may be terminated, the
proper selections made and a second attempt initiated.

Engine Failure To Start, ctd… AFM 3-11-10
Fuel ignition should result within five (5) to ten (10) seconds after
opening the HP fuel cock.
If there is no indication of ignition:
1. HP Fuel Cock .........................................................................SHUT
2. Start Master Switch .................................................................. OFF
END
Start Valve Failure AFM 3-11-20
FAILURE TO OPEN ON ENGINE START:
1. ENGINE START Circuit Breaker (P, K-6) ...........................CHECK
2. APU Air / External Air .......................................ON / CONNECTED
3. Bleed Air Pressure .............................. CHECK (25 PSI MINIMUM)
If air is available and pressure is adequate:
4. Another Start ...................................................................ATTEMPT
If start valve does NOT open:
5. Start................................................................................ABANDON
