TACHOMETER FAILURE
If rotor or engine tach malfunctions in flight, use remaining
tach to monitor RPM. If it is not clear which tach is
malfunctioning or if both tachs malfunction, allow governor
to control RPM and land as soon as practical.
NOTE
Each tach, the governor, and the low RPM
warning horn are on separate circuits. A
special circuit allows the battery to supply
power to the tachs with the battery and
alternator switches both OFF.
CYCLIC TRIM FAILURE
If the automatic cyclic trim fails to compensate for the
cyclic feed-back force, land as soon as practical. If the
trim generates undesirable forces, switch trim off and land
as soon as practical.
HYDRAULIC SYSTEM FAILURE
Hydraulic system failure is indicated by heavy or stiff
cyclic and collective controls. Loss of hydraulic fluid
may cause intermittent and/or vibrating feedback in the
controls. Control will be normal except for the increase in
stick forces.
1. HYD Switch – verify ON.
2. If hydraulics not restored, HYD Switch – OFF.
3. Adjust airspeed and flight condition as desired for
comfortable control.
4. Land as soon as practical.
GOVERNOR FAILURE
If engine RPM governor malfunctions, grip throttle firmly to
override the governor, then switch governor off. Complete
flight using manual throttle control.
