The vertical stabilizer has a 41 degree sweep-
back and is the mounting point for the rudder
and the horizontal stabilizer. The horizontal
stabilizer has a 29 degree sweepback and is at-
tached to the vertical stabilizer with a hinge
pin. The elevators feature three hinges per
side for a flutter-free, fail-safe configuration.
The delta fins, a honeycomb aluminum con-
struction, provide enhanced stability and pre-
vent the deep stall characteristic of T-tail
aircraft. Another benefit of delta fins is that
Dutch roll tendencies are dampened out very
quickly. The aerodynamic effect of the delta
fins has eliminated the need for a stick pusher
system and reduces the need for a yaw damper.
On aircraft 45-005 thru 45-225 with SB 45-55-
6, and aircraft 45-226 & subsequent a strap-
ping is added to the rudder and rudder trim tab.
These tabs reduce yaw oscillations (Dutch
roll) during flight.
STATIC DISCHARGE WICKS
There are four static discharge wicks on each
winglet, two on each delta fin, three on each
elevator and one on the trailing edge of the
vertical stabilizer bullet fairing, for a total
of nineteen (Figure 1-20). All discharge
wicks must be intact for flight, or as speci-
fied by the Minimum Equipment List (MEL),
as applicable.
