HYDRAULIC SYSTEM FAILURE
Indications:
Single system failure: The ‘
‘1HYD’’ or ‘‘HYD2
’’ caution annunciator illuminated
on the caution/warning advisory display. Both hydraulic system pressures or
‘‘TEMPERATURE’’ indication will be displayed on the IIDS alphanumeric
display. A stiffness in the anti−torque pedals will occur with a failure of the
number 2 system.
Dual system failure: The ‘‘
1HYD2
’’ caution annunciator illuminated on the
caution/warning advisory display. Both hydraulic system pressures or
‘‘TEMPERATURE’’ indications will be displayed on the IIDS alphanumeric
display.
Conditions: Single system failure − loss of pressure
Procedures:
F
Decrease air speed to below 100 KIAS.
NOTE
: A stiffness in the anti–torque pedals will occur with a failure of the number 2
system.
F
Continue the flight to the point of next intended landing.
F
Perform a shallow approach to a hover; land vertically for a single system
failure.
Conditions:
Dual system failure − loss of pressure
Procedures:
F
Decrease air speed to below 100 KIAS.
F
Continue the flight to the point of next intended landing.
F
Perform a running landing.
Conditions: High hydraulic fluid temperature
Procedures:
F
Land as soon as practical.
CYCLIC TRIM FAILURE
Indications: Cyclic trim failure is indicated by an inability to reduce cyclic forces with the
cyclic trim switch. Cyclic stick forces of approximately 15 pounds may be
required for full control movement.
Procedures:
F
Continue flight
