LIMIT
Failure of input
pressure load
limiter (with
flight and combined
system
pressure normal).
Avoid abnormal rudder deflection.
SPD BRAKE
EXTENDED
Speed brakes
(flight spoilers)
are deployed
with throttles
above idle.
Retract speed brakes or reduce
thrust as desired.
SSEC DISABLED Static source
error correction
to DADC has
been disabled.
Check the appropriate radio rack
DADC test switches.
STAB-FLAP FAIL Flaps UP (0°)
and stabilizer
not UP.
1. Lower flaps to correspond with
stabilizer position to prevent
running out of longitudinal trim.
2. Maintain airspeed within flap
position limits.
3. See Failure of Stabilizer /
Flap Interconnect, page EE-
6.

Stall barrier
system giving
stall angle
indication.
1. If either valve light is
illuminated, check airplane
attitude, power, and airspeed.
2. If primary instruments indicate
normal conditions, disable
system by pulling the STALL
WARN CMPTR circuit breaker
(STALL WARN CMPTR #1:
CPO, A-11; STALL WARN
CMPTR #2: CPO, B-11.)
3. Full protection is provided by
operative system.

normal for
STALL
BARRIER 1 FL
to appear any
time
EMERGENCY
FLAPS are
used and flap
position is
greater than
22°.
1. Check STALL BARRIER and
STALL BARR VALVE circuit
breakers (STALL BARR
VALVE #1: CPO, A-12; STALL
BARR VALVE #2: CPO, B-12;
STALL BARRIER #1: CPO, A-
9; STALL BARRIER #2: CPO,
B-9.)
2. Pull faulty barrier breakers.
3. Stall barrier protection is still
available with one system
operative.
STALL BARRIER
OFF
Stall barrier
switch OFF or
system not
powered.
1. Check stall barrier switch ON
("OFF" light out).
2. If on, check STALL BARRIER
and STALL BARR VALVE
circuit breakers (STALL BARR
VALVE #1: CPO, A-12; STALL
BARR VALVE #2: CPO, B-12;
STALL BARRIER #1: CPO, A-
9; STALL BARRIER #2: CPO,
B-9.)

Message: Cause(s): Corrective Action:
STEER BY WIRE
FAIL
Both steering
channels have
failed: steering
not available.
System is in
shimmy damp
mode.
With ASC 176
installed, a
switch position /
system status
miscompare is
detected.
1. Check circuit breakers (STEER
BY WIRE #1: CPO, C-12;
STEER BY WIRE #2: CPO, D-
12.)
2. Cycle steering ON/OFF switch.
3. If message does not clear, use
rudder, brakes, and/or
differential power for steering.
4. If message occurs on ground
with no hydraulic power
available, turn power switch
OFF until engines are running.
5. Reselect power switch ON.
If message occurs in flight: see
Nose Wheel Steering Failure,
page EG-6.
TAT PROBE HT
FAIL
TAT probe
heater has
failed.
1. TAT inputs to DADCs may be
inaccurate.
2. DADC outputs and FMS
readouts may be inaccurate.
3. Check circuit breaker (TOTAL
TEMP PROBE HTR: CP, L-10.)
TRIM LIMIT Autopilot
elevator trim
has reached
electric trim
limits.
Cycle PITCH TRIM switch to
DISENGAGE position and
manually trim, as required.
TRU FAIL Transformer
rectifier has no
output.
1. Check that L or R MAIN AC
bus is powered.
2. Check that the MAIN DC Bus
EPMP TRU/EXT switchlight is
illuminated.
3. If not, TRU/EXT switch - PUSH.
4. Check both TRU circuit
breakers on Power Distribution
Box.
5. If still no power, reduce load to
below 250 Amps and return
Main DC Bus Switch to AUTO.
