DA 42 AFM Airplane Description
Doc. No. 7.01.05-E Rev. 8 15-Dec-2017 Page 7 - 7
Elevator
Construction: GFRP sandwich.
Hinges: 5 hinges.
Operation: Steel pushrods;
Two of the bellcrank bearings are accessible for visual inspection next
to the lower hinge of the rudder. The elevator horn and its bearing, as
well as the connection to the pushrod, can be visually inspected at the
upper end of the rudder.
Variable Elevator Stop:
The DA 42 is equipped with an electrically operated actuator that limits the elevator-up
travel to 13° as soon as the power setting of both engines exceeds approximately 20 %
(approach power setting) and the flap selector switch is set to LDG. This is 2.5° less than
the 15.5° full deflection.
The linear actuator acts as a movable stop and is controlled by three switches, one for
each power lever and one for the flap selector. When the power of one engine is reduced
below approximately 20 %, or the flap selector is not in the LDG position, full elevator
deflection is regained.
An amber annunciation (CAUTION) on the G1000 display is provided to inform the pilot
in case a malfunction occurs. The annunciation illuminates when the variable stop should
be in place and is actually not activated (power on condition) or should be retracted and
actually limits the elevator travel (power off condition).
