AIRFRAME

(Continued)
The empennage (tail assembly) consists of a conventional vertical
stabilizer, rudder, horizontal stabilizer, and elevator. The vertical
stabilizer consists of a forward and aft spar, formed sheet metal ribs
and reinforcements, four skin panels, formed leading edge skins, and a
dorsal fin.
The rudder is constructed of a forward and aft spar, formed sheet metal
ribs and reinforcements, and a wrap-around skin panel. The top of the
rudder incorporates a leading edge extension which contains a balance
weight.
The horizontal stabilizer is constructed of a forward and aft spar, ribs
and stiffeners, four upper and four lower skin panels, and two left and
two right wrap-around skin panels which also form the leading edges.
The horizontal stabilizer also contains dual jack screw type actuators
for the elevator trim tabs.
Construction of the elevator consists of a forward and aft spar, sheet
metal ribs, upper and lower skin panels, and wrap-around skin panels
for the leading and trailing edges. An elevator trim tab is attached to the
trailing edge of each elevator by full length piano-type hinges. Dual
pushrods from each actuator located in the horizontal stabilizer transmit
actuator movement to dual horns on each elevator trim tab to provide
tab movement. Both elevator tip leading edge extensions provide
aerodynamic balance and incorporate balance weights. A row of vortex
generators on the top of the horizontal stabilizer just forward of the
elevator enhances nose down elevator and trim authority.
