FUEL CONTROL UNIT MALFUNCTION IN THE
PNEUMATIC OR GOVERNOR SECTIONS
(Continued)
CAUTION
WHEN USING THE FUEL CONTROL MANUAL
OVERRIDE SYSTEM, ENGINE RESPONSE MAY BE
MORE RAPID THAN WHEN USING THE POWER LEVER.
UTILIZE SLOW AND SMOOTH MOVEMENT OF THE
EMERGENCY POWER LEVER TO AVOID ENGINE
SURGES,
AND/OR EXCEEDING ITT, Ng, AND TORQUE
LIMITS.
NOTE
When using the emergency power lever, monitor gas
generator RPM when reducing power near idle, to keep
it from decreasing below 65% in flight.
The emergency power lever may have a dead band,
such that no engine response is observed during the
initial forward travel from the IDLE position.
GEAR BOX CONTAMINATION
Contamination of the reduction gear box as evidenced by the chip
detector annunciator being illuminated does not by itself demand any
~mmediare action by the $lot. If this annunciation-is accompanied by
slgns of engine d~stress (fluctuat:on in engine power gage indications or
erratic enghe operation'), engine operafion may be continued at the
discretion of the pilot consistent with crew safety. However, the power
gages should be closely monitored for further degradation in the torque
or RPM indications or engine operation which implies that seizure is
imminent. The engine failure checklist should be completed at that
time.
