VERTICAL STABILIZER
1. DESCRIPTION
The vertical stabilizer is the fixed vertical surface on the airplane empennage in which the rudder is hinged
to. The vertical stabilizer consists of two C-channel spars fabricated from S2 uni-directional and 7781 bi-
directional fiberglass. Two ribs are bonded to the spars at WL 131.25 and WL 159.50 and the right and left
fuselage skins cover the ribs and spars to form a two cell box beam structure that resists bending and tor-
sion created by air loads (wind gust and aircraft maneuvers). The right and left fuselage skins cover the
ribs and spars forming the torsion box. Three hinges attached to the aft spar support the rudder and rudder
horn.
2. MAINTENANCE PRACTICES
Because the vertical stabilizer is made from composite laminate materials and is molded to the empen-
nage, no servicing is required.
