EMERGENCY PROCEDURES
PA-31T2, CHEYENNE II XL
3.37 FLAP SYSTEM MALFUNCTION
In the event the "FLAP" annunciator should illuminate, the flap selector
switch should be checked for proper operation. If the flaps respond to
command an internal component of the amplifier has failed. The flaps are
still usable and the amplifier should be repaired before the next flight. If the
flaps do not respond a flap system shutdown has occurred. Check the flap
symmetry. The amplifier may have shut down the system because it detected
a 5° differential in flap position or one of the rheostats may have failed.
Determine through control wheel input that an asymmetric condition does
not exist (i.e., the control wheel is not displaced in the direction of the larger
flap deflection angle to maintain heading). Check and reset the flap motor
circuit breaker. If the flaps still remain inoperative, a rheostat may have
failed. The shutdown will remain until the system has been repaired.
When the flap selector becomes inoperative and the annunciator does
not illuminate, check the flap position indicator.
If
the indicator is pointing
to OFF, power has been lost to the amplifier. Without power the amplifier
cannot activate the annunciator. Check and reset the flap control circuit
breaker. If the indicator is showing the flap position, test the annunciator for
proper operation. If the annunciator fails to illuminate, proceed as a system
"·
shutdown and determine the cause. When it has been determined that
shutdown was not caused by an asymmetric flap condition, check and reset
the flap motor circuit breaker. If the annunciator functions properly when
tested, check and reset the flap motor circuit breaker.
3.39 ALTERNATE STATIC SOURCE
In the event the alternate static source must be used, the control lever
located on the instrur,ent panel to the right of the control pedestal should be
moved to the right (AL TERNA TE SOURCE).
Correct the airspeed and altimeter indications using the correction
graphs provided in Section 5.
3.41 FLIGHT WITH PRIMARY LONGITUDINAL CONTROL FAILED
When ready for the landing approach, trim the airplane in level flight to
121-135 KIAS. Select the longest runway in the area.
