Engine damage suspected or intentional shutdown:
Yes
(11) Single engine procedures.................... Accomplish Refer to SINGLE ENGINE
PROCEDURES in this
chapter.
− END −
No
(11) Affected engine ...................................................Relight Refer to AIR START section in
this chapter.
NOTE
1. Do not attempt to relight an engine that is suspected to be
not serviceable.
2. Relight engine using starter-assisted cross bleed whenever
possible.

REV 71, Oct 31/07
DOT Approved
CL−604 Airplane Flight Manual
PSP 604−1
1. POWER PLANT (CONT'D)
C. APR Failure
Indication: APR INOP caution message on.
N1 amplifier failure is suspected:
Yes
At a safe altitude:
(1) Both thrust levers......................................... Retard to below 79% N2.
(2) ENGINE CONTROL, both
ENG SPEED switches.....................................OFF to prevent asymmetric thrust.
APR INOP caution message
on (only if failure occurs within
5 minutes after take-off roll).
(3) ENGINE CONTROL, APR
switch...............................................................OFF APR INOP caution message
on.
NOTE
Use APR-off performance. Refer to Chapter 6;
PERFORMANCE.
(4) Thrust levers.............................................Advance as required.
NOTE
Thrust lever controls are more sensitive to changes.
− END −
No
(1) No further action required.
END
D. Inadvertent APR Command
Indication: APR CMD SET caution message. (APR CMD SET caution message may be
accompanied by APR operation on one or both engines.)
On the ground:
Yes
(1) Do not take off.
− END −
No
In flight:
(1) Thrust levers.........................................................Adjust to within normal thrust range.
(2) ENGINE CONTROL, APR switch............................OFF
(3) Engine performance ...........................................Monitor during approach.

CL−604 Airplane Flight Manual
PSP 604−1
1. POWER PLANT (CONT'D)
E. Uncommanded Deceleration or Abnormal Engine Oscillation/Fluctuation
Indication: Engine thrust does not agree with thrust lever selection.
NOTE
To prevent engine overspeed when selecting ENG SPEED switches
OFF, N2 indications should be referenced instead of N1.
(1) Affected thrust lever .............................................Adjust to below 79% N2 or IDLE
(whichever occurs first).
(2) Affected ENGINE CONTROL,
ENG SPEED switch ................................................OFF
(3) Affected thrust lever .........................................Advance
CAUTION
Do not change power settings abruptly as engine response is degraded.
(4) Affected engine ..................................................Monitor
Engine responds:
Yes
NOTE
1. To minimize asymmetric thrust, both ENG SPEED
switches should be selected OFF prior to approach and
landing.
2. Exercise caution to prevent overspeed during thrust
reverse use, when operating with ENG SPEED
switches OFF.
3. The APR system is inoperative when the ENG SPEED
switches are selected OFF.
− END −
No
(5) In-Flight Engine Failure/Shutdown .............. Accomplish Refer to In-Flight Engine
Failure/Shutdown procedure in
this section.

REV 66, Feb 01/07
DOT Approved
CL−604 Airplane Flight Manual
PSP 604−1
1. POWER PLANT (CONT'D)
F. N1 Fan Vibration
Indication: FAN VIB readout greater than 2.7 Mils.
CAUTION
It is not recommended that an engine be shut down unless there is
another indication of a severe engine abnormality, i.e., high oil
temperature, high oil pressure, abnormal increase in ITT, ITT
exceedance, or abnormal engine vibration is felt through the airframe.
NOTE
1. If engine was started within 2 hours of shutdown, allow 10 minutes
for vibration levels to return to normal.
2. An ITT increase of more than 10°C, from stable, matched N1 power
is an abnormal increase.
Icing conditions:
Yes
(1) Affected thrust lever......................................Adjust N2 to above 80%, and N1 to
above 70%.
Do not exceed maximum
continuous thrust setting.
Maintain thrust settings until
vibration is reduced.
