PILOT MUST TAKE ACTION TO FULLY FEATHER THE PROPELLER (ON THE AFFECTED ENGINE) TO REDUCE PROPELLER 

DRAG.

1. POWER LEVER (operating engine) ..................................................... SET MAXIMUM POWER

NOTE

• Commanding high propeller blade angle by keeping the 

power lever of the inoperative engine well forward will reduce windmilling propeller drag in the event that NTS failure accompanies 

engine failure.

• Set 650oC EGT or 100% torque, whichever occurs fi rst, during takeoff. If the 100% torque limit is not being developed and 

bleed air is ON, increased power may be obtained by selecting 

bleed air OFF.

ENGINE - PROPELLER UNCOUPLING

WARNING 

• IN THE EVENT OF ENGINE FAILURE IN CONJUNCTION 

WITH ENGINE UNCOUPLING, REDUCE WINDMILLING 

DRAG AS FOLLOWS:

• IF AN UNCOUPLING EVENT OCCURS WHERE THE ENGINE 

IS OPERATING AND THE PROPELLER IS STOPPED AND 

FEATHERED, RETARDING THE POWER LEVER TO FLIGHT 

IDLE MAY RESULT IN UNFEATHERING AND SUBSEQUENT 

ROTATION OF THE PROPELLER. IF THIS OCCURS, ADVANCE 

THE POWER LEVER TO MAXIMUM POWER POSITION.

• IN THE EVENT OF AN ENGINE WITH AN NTS AND/OR FEATHER VALVE MALFUNCTION, SETTING THE ASSOCIATED 

POWER LEVERS FULL FORWARD WILL DRIVE THE PROPELLER BLADES TOWARD THE FEATHER POSITION YIELDING A 

LOWER WINDMILLING PROPELLER DRAG AND PROPELLER 

SHAFT SPEED.

AIRSTART

CAUTION

IF AN ENGINE HAS BEEN SHUT DOWN BECAUSE OF AN OBVIOUS FAILURE, AS INDICATED BY THE ENGINE INSTRUMENTS 

OR EXCESSIVE VIBRATION, AN AIRSTART SHOULD NOT BE 

ATTEMPTED. AIRSTART FOLLOWING INTENTIONAL ENGINE 

SHUTDOWN IS COVERED IN SECTION 3A, ABNORMAL PROCEDURES.

NO RESPONSE TO POWER LEVER MOVEMENT

If either engine (or both) exhibits a lack of response to the power lever after extended operation at high 

altitude with OAT below freezing, the cause may be ice blockage of the PT2 inlet sensor probe. In certain

CABIN PRESSURIZATION MALFUNCTIONS

LOW PRESSURE MALFUNCTION

The cabin altitude warning light illuminates when the cabin pressure is equivalent to a pressure 

altitude between 10,000 feet and 12,000 feet. Check cabin altitude, differential pressure and controller 

setting. If the cabin pressurization controller is not providing proper cabin pressure, change to manual 

operation. If the desired cabin altitude or differential pressure still cannot be attained, an excessive leak 

exists and it may be necessary to descend or use oxygen.

HIGH PRESSURE MALFUNCTION

If the cabin differential pressure exceeds the normal limit of 7.0 psi, the cabin pressurization controller 

may have failed and allowed the outfl ow valve to close. Open the manual control valve approximately 1/2 

turn; select MANUAL position on the cabin pressure selector, and regulate pressure manually. If manual 

control is ineffective, the safety valve should relieve excess cabin pressure at 7.25 psi. Prior to landing, 

the cabin pressure differential must be eliminated by use of the manual control or the following alternate 

procedure:

 1. Altitude ............................................................................................................ BELOW 12,000 FEET

 *2. Bleed Air Switches ...................................................................................................................... OFF

 3. Allow cabin to depressurize to less than 1 psi differential.

 *4. Cabin Dump Switch .................................................................................................................DUMP

NOTE

If cabin pressure is dumped when a signifi cant cabin pressure differential exists, the resulting sensation may be alarming and uncomfortable to passengers. Consequently, use of the dump valve should 

normally be restricted to situations where cabin pressure differential 

is less than 1 psi or when other methods of pressure differential 

control are ineffective.

EXCESSIVE RATE OF PRESSURIZATION

If an excessive rate of pressurization is experienced and it cannot be controlled by the rate knob on 

the cabin pressurization controller or by the manual control knob, the following steps should be accomplished:

 *1. Bleed Air Switches ...................................................................................................................... OFF

 If Step 1 eliminates the excessive rate of pressurization, determine the source of the malfunction 

by turning the bleed air controls on individually. If the malfunction was caused by one of the bleed 

air control valves, leave the malfunctioning side off and continue pressurized fl ight using bleed air 

from one engine.

 If the pressure surge does not decrease:

 *2. Cabin Dump Switch .................................................................................................................DUMP

NOTE

If cabin pressure is dumped when a signifi cant cabin pressure differential exists, the resulting sensation may be alarming and uncomfortable to passengers. Consequently, use of the dump valve should

NOTE

• A pitch attitude of approximately 10 degrees nose down will

cruise power and airspeed.

CARGO OR CABIN DOOR WARNING LIGHT ON

PRIOR TO TAKEOFF

 1. Do not take off.

IN FLIGHT

A cabin door warning during fl ight could indicate that the cabin door handle is not fully closed, that one or 

more of the door latches is not fully extended, or that one or more of the door latch switches is maladjusted. 

The latter problem is typically annunciated when the cabin differential pressure reaches approximately 

5 psi during climbs. Reducing cabin differential pressure to less than approximately 4 psi will allow the 

pressure vessel to defl ate, the door latch to seat the switch, and the warning light to go out. If the door 

warning light should illuminate during fl ight, conduct the following:

 1. Keep crew and passengers clear of door.

 *2. Turn seat belts sign on.

 3. Reduce cabin differential pressure until the warning light goes out.

 4. Descend as required.

 5. Land as soon as practicable.

HYDRAULIC SYSTEM FAILURE

An emergency hand pump and a cable operated manual release system are provided to extend the 

landing gear in the event of a hydraulic system failure. A stand pipe system in the hydraulic reservoir 

provides a supply of fl uid for hand pump operation. The manual release system also permits free fall 

gear extension in the event that all hydraulic fl uid is lost.

There are no emergency provisions to extend or retract the fl aps. Landing approach should be made 

at 1.3 VS1 for the existing airplane confi guration. (For fl aps up confi guration, use 134 KIAS at 13,000 

pounds gross weight. Reduce this speed by 6 KIAS for each 1,000 pounds less gross weight.)

GEAR UP LANDINGS

NOTE

• If either main gear will not extend, land with all three gear up if 

possible. If the nose gear will not extend, land on the mains.

• Ensure that passengers are thoroughly briefed regarding 

bracing position and evacuation procedure.

• Depressurize airplane and consider removal and secure 

stowage of escape hatch prior to landing. Expect the entrance 

door to operate normally. It will not open fully after landings with 

the left main gear retracted.

• Historically, airplanes of this class have received more airframe 

damage from gear up landings on sod than from landings on 

smooth, paved surfaces.

• Propeller blades contacting the surface while turning under 

power tend to disintegrate and throw shrapnel which may puncture 

the fuselage. Blades contacting the surface when feathered, or 

nearly feathered, will bend slightly and wear away but most likely 

will not shatter and will aid in holding the wings and nacelles off 

the runway.

• The pilot may choose to feather one propeller early and save 

the other engine for last minute glide path corrections. During 

approaches with one main gear up and one down, it is recommended that the propeller on the gear up side be feathered fi rst. 

When a propeller is feathered with fl ight idle power set, drag will 

be reduced and gliding distance increased slightly.

SYSTEM (SAS2) MALFUNCTIONS

SAS FAULT LIGHT ON IN FLIGHT

1. SAS2 CLUTCH SWITCH ........................................................................................................... OFF

 2. SAS2 Computer Power Circuit Breaker .....................................................................................PULL

CAUTION

WITH THE SAS2 DISENGAGED (OR INOPERATIVE) THE AIRPLANE WILL HAVE UNDESIRABLE STALL CHARAC-TERISTICS 

AT AFT CENTER OF GRAVITY LOADINGS. ADEQUATE MARGINS 

ABOVE THE STALL SPEED SHOULD BE MAINTAINED IN ALL 

OPERATIONS. ENSURE THAT TOUCHDOWN SPEED IS EQUAL 

TO OR GREATER THAN 1.1 VS1.

NOTE

• With SAS2 disengaged or inoperative, there will be no augmented 

stick forces. Very light elevator forces will be required to maneuver 

the airplane at airspeeds below approximately 135 KIAS, particularly 

when operating at aft c.g. loadings.

• Fault light on fl ashing indicates a stopped servo or servo clutch 

disengagement.

• Fault light on steady in fl ight indicates computer power failure, or 

computer power failure with simultaneous servo or clutch failure.

• With the fault light on, angle of attack and stall warning indications 

may be unreliable.

AURAL STALL WARNING AT SPEEDS WELL IN EXCESS OF NORMAL STALL WARNING SPEEDS

When an aural stall warning occurs in unaccelerated fl ight at speeds well in excess of normal stall 

warning speed, possible damage to the SAS2 vane is indicated and an inadvertent nose down push 

may occur.

 *1. SAS2 CLUTCH SWITCH ........................................................................................................... OFF

To silence the stall warning horn:

 2. Stall Warning Circuit Breaker .....................................................................................................PULL

WARNING

PULL FORCES REQUIRED TO OVERPOWER THE STICK PUSHER 

MAY EXCEED 60 POUNDS.

NOTE

With SAS2 disengaged or inoperative, there will be no augmented 

stick forces. Very light elevator forces will be required to maneuver 

the airplane at airspeeds below approximately 135 KIAS, particularly 

when operating at aft c.g. loadings.

YAW DAMPER MALFUNCTIONS

The yaw damper warning light, located on the annunciator panel, illuminates when a power failure 

occurs. If such a failure occurs, the yaw damper switch should be turned OFF and care should be 

taken to avoid extreme skidding or slipping turns.

NOTE

Maximum allowable 90o crosswind component for landing with 

yaw damper inoperative is 10 knots.

YAW DAMPER MALFUNCTIONS (continued)

ELECTRICAL SERVO RUNAWAY

A runaway can occur when an erroneous electrical signal is transmitted to the yaw damper servo 

primary electrical clutch; however, the system is provided with a secondary mechanical clutch that prevents 

excessive rudder forces being generated. If a runaway occurs:

 1. Rudder Pedals .........................................................AS REQUIRED FOR COORDINATED FLIGHT

 2. Yaw Damper Switch .................................................................................................................... OFF

 3. Avoid extreme skidding or slipping turns.

EMERGENCY EXIT

There is one emergency exit on the right side of the center cabin. The hatch is of the plug type and 

opens into the cabin. To open the emergency exit:

 1. Cabin ..................................................................................................................... DEPRESSURIZE

 2. Hatch Release Handles .............................................................................PULL INBOARD AND UP

NOTE

Pull hatch inward, rotate, extend through opening, and discard 

outside the airplane. Ensure that the hatch is clear of the exit route 

from the airplane.

NOSE WHEEL STEERING ELECTRICAL MALFUNCTION

Fault protection is provided by circuitry which automatically deactivates the nose wheel steering 

system if an electrical malfunction occurs. The nose wheel is then free to caster and rudder, differential 

braking, and/or differential power can be used for steering.

If the system fails to test correctly, the arm switch should be placed in the OFF position and steering accomplished with rudder, differential braking, and/or differential power.

In the event of a fl ashing green NOSE STEERING light, an unwanted steering defl ection, and/or park 

light illuminated when the PARK button is not depressed:

 1. NWS Power Lever Button ..................................................................................................RELEASE

 2. Right Speed Lever ....................................................... APPROXIMATELY 1/2 INCH FWD OF LOW

 3. Directional Control ................................................................ MAINTAIN WITH RUDDER, BRAKES,

AND/OR POWER

 4. Nose Wheel Steering Arm Switch ............................................................................................... OFF

 5. Nose Wheel Steering Circuit Breaker ........................................................................................PULL

NOTE

It is normal for the park light to remain illuminated, but vary in 

intensity, during the 4 to 7 second transition time from park mode 

to normal mode.

NOSE WHEEL STEERING HYDRAULIC MALFUNCTION

An illuminated NOSE STEER FAIL amber annunciator light indicates that hydraulic pressure is being supplied to the nose wheel steering actuator but the pilot is not commanding a steering signal. Illumination 

of the NOSE STEER FAIL light should alert the pilot to potentially undesirable steering actuation and that 

corrective action may be required. Corrective action depends upon the operational phase.

NOTE

The following procedures assume that the NOSE STEER FAIL 

light illuminates while the nose wheel steering switch is in its 

ARMED position. Neither the NWS power lever button nor the 

right speed lever switch will be effective if the nose wheel steering 

switch is OFF. Therefore, if the NOSE STEER FAIL light illuminates 

while the switch is OFF, corrective action must be preceded by arming the nose wheel steering system.

NOSE STEER FAIL Light ON

(During ground operations):

 1. NWS Power Lever Button ...................................................................................PRESS AND HOLD

OR:

 2. Right Speed Lever ..................................................................................................................... LOW

 3. NOSE STEER FAIL Light ............................................................................................. CHECK OUT

 4. Directional Control .........................................................................................MAINTAIN WITH NWS

 5. Do Not Take Off.
