OIL PRESSURE UGHT ILLUMINATED (CONT)
• Oil pressure is between 25 and 38 psi or oil temperature
is high:
If flight conditions permit, reduce power to maintain oil tempera-
ture limits.
• Oil pressure and oil temperature are normal:
Continue to monitor engine operation.
BLEED AIR UGHT ILLUMINATED
• Aircraft 35-067 thru 35-081, 35-083 thru 35-086, and 36-018 thru
36-022 except aircraft incorporating AMK 76-7:
If either the BLEED AIR L or BLEED AIR R light illuminates, either the pri-
mary pressure regulator of the respective air modulating valve has failed or
an overheat sensor has tripped the
light.
1. Corresponding BLEED AIR Switch - OFF .
• Aircraft 35-082, 35-087 thru 35-106, 35-108 thru 35-112 and 36-023
thru 36-031 and previous aircraft incorporating AMK 76-7:
If both the BLEED AIR L and BLEED AIR R lights illuminate, the secondary
pressure regulator
of one of the air modulating valves has failed.
1. R BLEED AIR Switch - OFF.
• If both lights go out, continue flight in this configuration .
• If both lights do not go out, proceed to step 2.
2. R BLEED AIR Switch - On, and L BLEED AIR Switch - OFF.
• If both lights go out, continue flight in this configuration.
• If both lights do not go out, proceed to step 3.
3. Reduce power alternately on each engine until both lights go out.
Continue
flight with the appropriate engine at reduced power.
If either the BLEED AIR L or BLEED AIR R light illuminates, an overheat
sensor has tripped the
light.
1. Corresponding BLEED AIR Switch - OFF .
• Aircraft 35-107,35-113 and subsequent, and 36-032 and subsequent:
If either the BLEED AIR L or BLEED AIR R warning light illuminates, an
overheat sensor
in the bleed air ducting or the pylon structure has tripped
the
light.
1. Corresponding BLEED AIR Switch - OFF.
