SECTION 7
SYSTEMS DESCRIPTION
FLIGHT CONTROLS
Dual controls are standard equipment and all primary
controls are actuated through push-pull tubes and
bellcranks. Bearings used throughout the control system
are either sealed ball bearings which do not require
lubrication or have self-lubricated liners.
Flight control operation is conventional. The cyclic is center
mounted with the left and right control grips mounted to a
cross tube which pivots on the center cyclic post. On later
aircraft, the pilot’s cyclic grip angle can be adjusted fore
and aft relative to the cross tube by a mechanic to achieve
the most comfortable hand position. The most forward
position provides the most control clearance at aft cyclic
for larger pilots. Pilots should always verify the ability to
apply full control travel prior to flight.
Collective operation is conventional. The engine throttle
is correlated to collective inputs through a mechanical
linkage. When the collective is raised, the throttle is
opened and when the collective is lowered, the throttle is
closed. The collective stick also incorporates a twist grip
throttle control which is described in the Engine Controls
section.
CAUTION
Above 4000 feet, throttle-collective correla
-
tion and governor are less effective. There-
fore, power changes should be slow and
smooth.
CAUTION
At high power settings above 4000 feet, the
throttle is frequently wide open and RPM
must be controlled with collective.
On later aircraft, right-side tail rotor pedals are adjustable.
To adjust, remove quick-release pin on each pedal by
depressing button and pulling. Slide pedal fore or aft to
most comfortable of three adjustment positions and reinstall
quick-release pin. Verify pins are secure before flight.
