Illumination indicates melted or failed plastic bleed air failure warning line.  Monitor during engine start.  Either engine extinguishes both annunciators upon starting.

These annunciators may also momentarily illuminate during simultaneous wing boot and brake deice operation at low N1 speeds.  If annunciators immediately extinguish, disregard.

R BLEED FAIL (Red)

Illumination indicates melted or failed plastic bleed air failure warning line.  Monitor during engine start.  Either engine extinguishes both annunciators upon starting.

These annunciators may also momentarily illuminate during simultaneous wing boot and brake deice operation at low N1 speeds.  If annunciators immediately extinguish, disregard.

Illumination indicates that prop levers are not in the appropriate position of HIGH RPM/LOW PITCH with landing gear extended.

L CHIPDETECT (Amber)

Illumination indicates possible metal contamination in the forward gear reduction case oil supply.

R CHIPDETECT (Amber)

Illumination indicates possible metal contamination in the forward gear reduction case oil supply.

L NO FUELXFR (Amber)

Illumination indicates motive flow pressure lost while fuel remains in Auxiliary fuel tank on the designated side.  When the auto ignition system is activated, the motive flow valve on the corresponding side closes automatically; this illuminates the NO FUEL XFR annunciation.

 R NO FUELXFR (Amber)

Illumination indicates motive flow pressure lost while fuel remains in Auxiliary fuel tank on the designated side.  When the auto ignition system is activated, the motive flow valve on the corresponding side closes automatically; this illuminates the NO FUEL XFR annunciation.

BAT TIE OPEN (Amber)

Illumination indicates battery islolated from Generator buses.

DUCT OVERTEMP (Amber)

Illumination indicates floor distribution air duct temperature has reached 300 degrees F.

L ENG ICE FAIL (Amber)

Illumination indicates that the designated anti-ice vane system is inoperative.

R ENG ICE FAIL (Amber)

Illumination indicates that the designated anti-ice vane system is inoperative.

L FUEL QTY (Amber)

Illumination indicates that the designated side has less than 30 minutes fuel remaining at maximum continuous power.

R FUEL QTY (Amber)

Illumination indicates that the designated side has less than 30 minutes fuel remaining at maximum continuous power.

BATTERY CHARGE (Amber)

Illumination indicates that the battery is being charged.  Illumination in flight indicates charge rate is too high and a possible battery malfunction has occurred.

EXT POWER (Amber)

Illumination indicates that the external power connector is plugged in.  Steady illumination indicates external power supplied to aircraft.  Annunciator flashes when voltage is low or power unit is electrically disconnected from aircraft.

L BLAIR OFF (Amber)

Illumination indicates that the designated bleed air switch is not in OPEN position.

R BLAIR OFF (Amber)

Illumination indicates that the designated bleed air switch is not in OPEN position.

AUTOFTHER OFF (Amber)

Illumination indicates that the autofeather switch is not armed and landing gear is extended.

PITCH TRIM OFF (Amber)

Illumination indicates that a trim disconnect switch on the control wheel has de-energized electric trim while the ELEV TRIM switch on the pedestal is on.

OXY NOT ARMED (Amber)

Illumination indicates oxygen arming handle is not pulled or the system failed to charge.

RUD BOOST OFF (Amber)

Illumination indicates that the Rudder Boost switch is off.

PROP GND SOL (Amber)

Illumination indicates that the propeller ground idle stop solenoid has failed. (FL-115 and after, FM-10 and after, and FN-2 and after.)

L IGNITION ON (Green)

Illumination indicates that the designated ignition and start switch is in ON or that the auto ignition system is armed and engine torque is below 17%.

R IGNITION ON (Green)

Illumination indicates that the designated ignition and start switch is in ON or that the auto ignition system is armed and engine torque is below 17%.

L ENG ANTI-ICE (Green)

Illumination indicates designated engine anti ice vanes are in position for icing conditions.

R ENG ANTI-ICE (Green)

Illumination indicates designated engine anti ice vanes are in position for icing conditions.

Illumination indicates that the wing surface deice system is operating.

L BK DEICE ON (Green)

Illumination indicates that the designated brake deice system is operating.  If brake deice operation does not automatically terminate approximately 10 minutes after gear retraction, manually turn the system to OFF.  If inadequate pneumatic pressure develops for proper wing boot inflation, turn brake deice to OFF.

R BK DEICE ON (Green)

Illumination indicates that the designated brake deice system is operating.  If brake deice operation does not automatically terminate approximately 10 minutes after gear retraction, manually turn the system to OFF.  If inadequate pneumatic pressure develops for proper wing boot inflation, turn brake deice to OFF.
