YAW DAMPER MALFUNCTION
Any failure or malfunction of the yaw damper can be overridden by use of the
rudder pedals. If a yaw damper runaway occurs, disengage the yaw damper
by turning the yaw damper master switch to OFF. The yaw damper master
switch is located just below the autopilot computer on the instrument panel.

ALTITUDE LOSS
Maximum altitude lost during a roll, pitch, or yaw axis autopilot or yaw
damper malfunction is as follows:
Flight Phase Bank Angle Change Altitude Loss
Climb 59 600
Cruise 60 500
Descent 60 800
Maneuvering 40 100
Approach 29 100
Table 9.1-2 – Altitude Loss
SYSTEM FAILURE AND CAUTION ANNUNCIATIONS
Annunciations for the autopilot are shown on both the G1000 (top center
of the PFD) and the S-Tec 55X autopilot computer. If “FAIL” annunciation
is shown in the G1000 Autopilot Annunciation Block (see the gure below),
immediately disengage the autopilot and execute a go-around or missed
approach as appropriate. Do not attempt to troubleshoot the problem until
a safe altitude and maneuvering area are reached or a safe landing is
completed.
Figure 9.1-3 – G1000 Autopilot Annunciations
NOTE: The G1000 Annunciation block will also display the following
annunciations when activated: AP (Autopilot), FD (Flight Director), and YD
(Yaw Damper).
