Pilot’s Operating Handbook Section 7
EXTRA 500 Description of Airplane and Systems
7.3.c Elevator and Tab
The coupling between the control wheels is realized by a lever
system, which is connected to a cable segment. From this cable
segment the elevator cables run horizontally to the right cabin
side to a 90° pulley and parallel with the rudder cables to the
empennage. They are lead to the elevator in front of the front fin
spar and are attached to a lever positioned in front of the
horizontal stabilizer front spar, which actuates the two elevator
sides separately by means of push rods. Each elevator is
attached to the respective horizontal stabilizer by three bearings.
The mechanical pitch trim is actuated through a trim wheel in
the center console. The pitch trim tab is located in the right
elevator and is linked over a cable-lever system to the trim
wheel. The trim Bowden cable runs from the center console
down crossing the cabin floor and is then directed rearwards to
the empennage following the nose section of the fin to the right
side elevator.
