_
1-2.
a Put the throttle control levers of the engines 1 and 2 to
_ the idle stop position (zero on the graduated sector).

5 Another start may be tried if the engine indications before
_ the flameout, and the examination after the flameout, do not show an engine malfunction or failure.
(d) Oil system malfunction
(Ref. Fig. 506/TASK 71-00-00-991-309)
CAUTION : BE CAREFUL WHEN OPERATING AN ENGINE WITH OIL PRESSURE
_______ THAT IS OVER OR UNDER THE NORMAL PRESSURE RANGE. ENGINE DAMAGE CAN RESULT.
1 During cold conditions, it is permitted to go over 45 psi (3.1
_
bar) during starts.
2 It is also permitted to go over 90 psi (6.2 bar) at takeoff
_
before the engine warms up.
3 If oil pressure is more than 90 psi (6.2 bar) during
_ steady-state operation, it is usually an indication of an engine malfunction. Unless all other parameters are normal and it is definitely a known pressure indication error.
4 Examine the cause of any oil pressure fluctuation, or when the
_ pressure varies more or less than 5 psi (0.3 bar) from a steady-state operating pressure.
5 Operating an engine with the oil pressure less than the
_
minimum is not permitted.
6 Oil system malfunctions, and the effects of the malfunctions,
_
must be corrected.
(e) Scavenge oil overtemperature
CAUTION : OIL TEMPERATURES THAT ARE MORE THAN THE NORMAL
_______ STEADY-STATE TEMPERATURES CAN INDICATE A SYSTEM MALFUNCTION. MONITOR THIS CONDITION CLOSELY OR ENGINE DAMAGE CAN BE CAUSED.
1 The supply oil temperature limit for continuous operation is
_
140 deg.C (284 deg.F).

2_ Transient operation temperature limit of 155 deg.C (311 deg.F)
for less than 15 minutes is permitted.
3_ Temperatures above 140 deg.C (284 deg.F) must be written in
the Aircraft Log.
4_ If the engine has gone above the operational limits refer to
(Ref. TASK 72-00-00-200-008).
(f) Engine overtemperature 1 Obey the EGT limits in (Ref. TASK 72-00-00-200-008). Any
_ temperatures more than these are overtemperatures.
2 Write the length of time an overtemperature lasts, and the
_ temperature reached, in the Aircraft Log.
3 If the engine has gone above the operational limits refer to
_ (Ref. TASK 72-00-00-200-008).
(g) Internal engine fire CAUTION : TRY TO EXTINGUISH INTERNAL FIRES BY MOTORING THE ENGINE
_______ FIRST. USE FIRE EXTINGUISHING AGENTS ONLY WHEN MOTORING DOES NOT WORK. IF EXTINGUISHING AGENTS ARE USED, A MAJOR INSPECTION CAN BE NECESSARY.
1 An internal engine fire (post-shutdown burning), can be
_ identified by a failure of the EGT to go down after placing ENG MASTER 1(2) switch in the OFF position.
2 If an internal engine fire occurs during ground operation, use
_ the procedure that follows:
3 On the ENG panel 115VU:
_
- Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to CRANK.
4 On the overhead CTL & IND panel 22VU:
_
- Push the ENG/MAN START/1(2) pushbutton switch. 5 Ignore the starter time limits and dry motor the engine until
_ you remove all indications of a fire, then complete the shutdown procedure (Ref. TASK 71-00-00-710-028).
