Emergency Procedures EXTRA 500
3-60 26. January 2011
4 FUEL FILTER BYPASS y

open (or is open) because its filter element is clogged.
Fuel Pressure ; Check
Aircraft Fuel Filter Element; Replace
within 2 hours of flight
3.5.k Propeller Malfunctions
1 LOW PITCH y
This caution means the propeller is commanded to be in ‘beta’
range and thus the propeller RPM is no longer controlled by the
governor.
Power Lever ; Move forward
Note In case of propeller problems e.g. oil pressure loss etc.,
propeller feathering is accomplished by the condition lever
set to “FEATHER” position.
3.5.l Electrical System Malfunctions
Note In case of a generator failure, the load bus will be
automatically shed.
1 GENERATOR FAIL r
This warning means the generator relay is open and thus only
battery and standby alternator power is available (and external
power if connected and on). The Load bus will be without
power. The cause can be the
GEN switch being off or the
generator control unit (GCU) has sensed a fault or is faulty
itself.
GEN; RESET
(hold for approx. 2 seconds and back to
ON)
If GENERATOR FAIL extinguishes:
VDC; Check
28
GEN AMPS; Check indication
Flight; Continue
If GENERATOR FAIL still illuminates:
