Emergencies caused by airplane or engine malfunctions are extremely rare if proper preflight inspections and maintenance are practiced. Enroute weather emergencies can be minimized or eliminated by careful flight planning and good judgment when unexpected weather is encountered. However, should an emergency arise, the basic procedures described in this section should be considered and applied as necessary to correct the problem. Emergency procedures associated with ELT and other supplemental systems can be found in Section 9 of the Cessna POH/AFM. Emergency procedures relating to Known Icing Equipment and the Standby Alternator System can be found in Section 9 of this airplane flight manual supplement. WARNING THERE IS NO SUBSTITUTE FOR PROPER AND COMPLETE PREFLIGHT PLANNING HABITS AND THEIR CONTINUAL REVIEW IN MINIMIZING EMERGENCIES. BE THOROUGHLY KNOWLEDGEABLE OF HAZARDS AND CONDITIONS WHICH REPRESENT POTENTIAL DANGERS, AND BE AWARE OF THE CAPABILITIES AND LIMITATIONS OF THE AIRPLANE.

Visible rain at temperatures below 0 degrees Celsius ambient air temperature. 2. Droplets that splash or splatter on impact at temperatures below 0 degrees Celsius ambient air temperature. PROCEDURES FOR EXITING THE SEVERE ICING ENVIROMENT (Required by AD 96-09-15, Paragraph (a) (2)): These procedures are applicable to all flight phases from takeoff to landing. Monitor the ambient air temperature. While severe icing may form at temperatures as cold as -18 degrees Celsius, increased vigilance is warranted at temperatures around freezing with visible moisture present. If the visual cues specified in Section 2 Limitations for identifying severe icing conditions are observed, accomplish the following: 1. Immediately request priority handling from Air Traffic Control to facilitate a route or an altitude change to exit the severe icing conditions in order to avoid extended exposure to flight conditions more severe than those for which the airplane has been certificated. 2. Avoid abrupt and excessive maneuvering that may exacerbate control difficulties. 3. Do not engage the autopilot 4. If the autopilot is engaged, hold the control wheel firmly and disengage the autopilot. 5. If an unusual roll response or uncommanded roll control movement is observed, reduce the angle-of-attack. 6. If the flaps are extended, do not retract them until the airframe is clear of ice. 7. Report these weather conditions to Air Traffic Control. INADVERTENT ICING ENCOUNTER 1. Ignition Switch – CONT. 2. Engine Inlet Anti-ice Switch – ON. 3. PITOT/STATIC, STALL, WINDSHIELD, PROP ANTI-ICE – ON. 4. If above 20,000 feet: a) Airspeed – 160 KIAS Maximum. b) Altitude – DESCEND to 20,000 feet or below as soon as practical. 5. Turn back or change altitude to obtain an outside air temperature that is less conducive to icing. 6. Ignition Switch – AUTO after 5 minutes operations. 7. Bleed Air Heat Switch and Temp Control – ON and ADJUST 8. Push Fwd Cabin Heat control full in and pull Defrost control full out to obtain maximum windshield defroster effectiveness. 9. Speed Lever – INCREASE to 100% RPM to minimize ice build-up. CAUTION IF EXCESSIVE VIBRATION IS NOTED, MOMENTARILY REDUCE PROPELLER RPM TO 96% WITH THE SPEED LEVER, THEN RAPIDLY MOVE THE CONTROL FULL FORWARD. CYCLING THE RPM FLEXES THE PROPELLER BLADES AND HIGH RPM INCREASES CENTRIFUGAL FORCE, CAUSING ICE TO SHED MORE READILY. 10. If icing conditions are unavoidable, plan a landing at the nearest airport. With an extremely rapid ice build-up, select a suitable “off airport” landing site. Supervan Systems, Ltd.

With an ice accumulation of ¼ inch or more on the wing leading edges, be prepared for a significantly higher power requirement, approach speed, stall speed, and longer landing roll. 12. If necessary, set up a forward slip for visibility through the left portion of the windshield during the landing approach. 13. Use a minimum approach speed of 110 KIAS, select the minimum flap setting required, and maintain extra airspeed consistent with available field length. With ice suspected on the airframe, or operating at 5ºC (41ºF) or less in visible moisture, Do Not Extend Flaps Beyond 10º for Landing. WARNING WITH HEAVY ICE ACCUMULATIONS ON THE HORIZONTAL STABILIZER LEADING EDGE, DO NOT EXTEND FLAPS WHILE ENROUTE OR HOLDING. WHEN LANDING IS ASSURED, SELECT THE MINIMUM FLAP SETTING REQUIRED, NOT TO EXCEED 10º, AND MAINTAIN EXTRA AIRSPEED CONSISTENT WITH AVAILABLE FIELD LENGTH. DO NOT RETRACT THE FLAPS ONCE THEY HAVE BEEN EXTENDED, UNLESS REQUIRED FOR GO-AROUND. THEN RETRACT FLAPS IN INCREMENTS WHILE MAINTAINING 5 TO 10 KNOTS EXTRA AIRSPEED. 14. Land on the main wheels first, avoiding a slow and high flare-out. 15. Missed approaches should be avoided whenever possible because of severely reduced climb capability. However, if a go-around is mandatory, make the decision much earlier in the approach than normal. Apply takeoff power and maintain a minimum of 110 KIAS while retracting the flaps slowly in small increments. STATIC SOURCE BLOCKAGE (Erroneous Instrument Reading Suspected) 1. Static Pressure Alternate Source Valve – PULL FULL ON. NOTE The alternate static source is connected to the left-hand flight panel instruments only. 2. Refer to Section 5 of the Cessna POH/AFM for airspeed and altimeter corrections. 3. Autopilot – DISENGAGE altitude hold mode. Supervan Systems, Ltd.

If oil pressure gage confirms annunciator warning, proceed in accordance with Engine Failures checklists or at the discretion of the pilot and consistent with safety, continue engine operation in preparation for an emergency landing as soon as possible. FUEL CONTROL MALFUNCTION If there is an indication of improper operation of the fuel control, when possible, check the handling of the aircraft by a simulated landing flare at a safe altitude before trying to land. If unusual drag is noted that cannot be eliminated by increasing the power, it may be necessary to feather the propeller when the pilot has the runway made. ENGINE INLET ANTI-ICE AND CONTINUOUS IGNITION Engine inlet anti-ice (inlet heat) should be used during all flight in potential icing conditions. These conditions exist when flying in precipitation or visible moisture (including clouds or fog), with OAT of 5ºC (41ºF) or less. Select Ignition Switch to CONT as below: 1. During takeoff or approach, before operation in icing conditions. 2. When ice is observed shedding from the propeller and/or spinner. 3. Before applying inlet heat, when ice has accumulated. 4. Immediately, any time engine flameout occurs as a possible result of ice ingestion. NON-RESPONSIVE POWER LEVER If a lack of response to the power lever is observed: 1. Ignition switch – CONT. 2. Engine Inlet Anti-ice Switch - ON. After the engine has cleared and normal operation is observed, which occurs in approximately three minutes: 3. Engine Inlet Anti-ice – OFF. 4.

These procedures also include information not readily adaptable to a checklist format, and material to which a pilot could not be expected to refer in resolution of a specific emergency. NOTE If a red or non-dimmable amber annunciator illuminates at night and becomes an unacceptable distraction to the pilot because of its brightness level, it may be extinguished for the remainder of the flight by pushing in on the face of the light assembly and allowing it to pop out. To reactivate the annunciator, pull the light assembly out slightly and push back in. For further details, refer to Section 7, Annunciator Panel. ENGINE FAILURE If an engine failure occurs during the takeoff roll, the most important thing to do is stop the airplane on the remaining runway. Those extra items on the checklist will provide added safety after a failure of this type. Prompt lowering of the nose to maintain airspeed and establish a glide attitude is the first response to an engine failure after takeoff. Feathering the propeller substantially reduces drag, thereby providing increased glide distance. In most cases, the landing should be planned straight ahead with only small changes in direction to avoid obstructions. Altitude and airspeed are seldom sufficient to execute a 180º gliding turn necessary to return to the runway. The checklist procedures assume that adequate time exists to secure the fuel and electrical systems prior to touchdown. After an engine failure in flight, the best glide speed as shown in Figure 3-1 should be established as quickly as possible. Propeller feathering is dependent on existing circumstances and is at the discretion of the pilot. Maximum RPM selection will provide increased engine wind milling speed for emergency restarts. On the other hand, to obtain the maximum glide, the propeller must be feathered. While gliding toward a suitable landing area, an effort should be made to identify the cause of the power loss. An engine failure might be identified by abnormal temperatures, mechanical noises or high vibration levels in conjunction with the power loss. A flameout will be noticed by a drop in EGT, torque, and RPM. CAUTION DO NOT ATTEMPT TO RESTART AN ENGINE THAT IS DEFINITELY KNOWN TO HAVE HAD A MECANICAL FAILURE. A flameout may result from the engine running out of fuel, or possibly may be caused by unstable engine operation. Once the fuel supply has been restored to the engine or cause of unstable engine operation eliminated, the engine may be restarted. Supervan Systems, Ltd.

Regardless of airspeed or altitude, there is always the possibility that the engine may light up successfully just as soon as the ignition is turned on. In an emergency, turn on the ignition just as soon as possible after a flameout, provided the engine speed has not dropped below 60%. Under these circumstances, it is not necessary to shut off the fuel or feather the propeller. The power lever, however, should be retarded to IDLE position. If a flameout has occurred and the engine speed has dropped below 60%, the fuel valve switch should be moved to the OFF position before an airstart is attempted. CAUTION THE PILOT SHOULD DETERMINE THE REASON FOR POWER LOSS BEFORE ATTEMPTING AN AIRSTART. Supervan Systems, Ltd. Cessna 208B/TPE331-12JR Landplane 10699 Private Road 5117 Airplane Flight Manual Supplement Celina, Texas 75009 SSL-FMS-208B-12JR (972) 382-2500 Section 3: Emergency Procedures Rev. 5 3-21 November 7, 2019 FAA Approved Propeller feathering is dependent on circumstances and is at the discretion of the pilot. However, if engine oil pressure drops below 40 psi, the engine should be shut down and the propeller should be feathered unless a greater emergency exists. Typically, as oil pressure decreases, propeller control may become an issue necessitating engine shutdown. If an airstart is to be attempted, follow the checklist procedures. Wind-milling air starts utilizing the propeller unfeathering pump are the only type of airstart available. Attempting a starter-assisted airstart can shear the starter shaft due to the high torque loads of a feathered propeller. Successful air starts may be achieved at all airspeeds above 90 kts from sea level up to an altitude of 20,000 feet. However, start temperatures tend to be higher at slower airspeeds. CAUTION IF A RISE IN RPM AND EGT ARE NOT INDICATED WITHIN 10 SECONDS, PLACE FUEL VALVE SWITCH TO OFF AND ABORT START. REFER TO ENGINE FAILURE DURING FLIGHT AND EMERGENCY LANDING WITHOUT POWER CHECKLISTS. CAUTION EMERGENCY AIRSTARTS MAY BE ATTEMPTED BELOW 10% RPM AND OUTSIDE THE NORMAL AIRSPEED ENVELOPE, BUT EGT SHOULD BE CLOSELY MONITORED. A MANUAL AIRSTART (SRL “OFF”) WITHOUT THE USE OF FUEL ENRICHMENT CAN BE PERFORMED IF START TEMPERATURES ARE TOO HIGH WITH THE SRL SYSTEM ON. REFER TO THE AIRSTART CHECKLIST FORCED LANDINGS If all attempts to restart the engine fail and a forced landing is imminent, select a suitable field and prepare for the landing as discussed in the Emergency Landing Without Engine Power checklist. Before attempting an “off airport” landing with engine power available, one should fly over the landing area at a safe, but low altitude to inspect the terrain for obstructions and surface conditions, proceeding as discussed in the Precautionary Landing With Engine Power checklist. NOTE The overhead fuel tank selectors control shutoff valves at the wing fuel tank outlets. To minimize the possibility of a fire, these selectors can be set to the OFF position during the final stage of an approach to an “off airport” landing. With the selectors turned OFF, there is adequate fuel in the fuel reservoir tank for 2.5 minutes of maximum continuous power operation or approximately 9 minutes idle power operation. A warning horn will sound with both fuel selectors turned OFF. If it is objectionable, it may be silenced by pulling the START CONT circuit breaker. WARNING IF THE PRECAUTIONARY LANDING IS ABORTED, TURN THE FUEL TANK SELECTORS TO THE “ON” POSITION AFTER INITIATING THE BALKED LANDING. Prepare for ditching by securing or jettisoning heavy objects located in the baggage area and collect folded coats for protection of occupants’ face at touchdown. Transmit Mayday message on 121.5 MHz giving location and intentions and squawk 7700 if a transponder is installed. Avoid a landing flare because of difficulty in judging height over a water surface.

Then control the glide angle by adjusting power. If required, make small trim changes to maintain approximately 85 KIAS as power is adjusted during the approach. The landing flare can be accomplished by a gentle power reduction accompanied by nose up trim. At forward C.G. loadings, it may be necessary to make a small power increase in the final flare stage to bring the nose up and prevent touchdown on the nose first. After touchdown, move the power lever to idle. SMOKE AND FIRE In the event a fire is encountered, the following information will be helpful in dealing with the emergency as quickly and safely as possible. The preflight checklist in Section 4 is provided to aid the pilot in detecting conditions which could contribute to an airplane fire. As a fire requires a combustible material, oxygen and a source of ignition, close preflight inspection should be given to the engine compartment and the underside of the wing and fuselage. Leaks in the fuel or oil systems can lead to a ground or in-flight fire. WARNING FLIGHT SHOULD NOT BE ATTEMPTED WITH KNOWN FUEL OR OIL LEAKS. THE PRESENCE OF FUEL OR UNUSUAL OIL STAINS MAY BE AN INDICATION OF SYSTEM LEAKS AND SHOULD BE CORRECTED PRIOR TO FLIGHT. Probable causes of an engine fire are a malfunction of the fuel control unit and improper starting procedures. Improper procedures, such as introducing fuel into the engine when the engine RPM is below 10% RPM, will cause a hot start which may result in an engine fire. In the event that this occurs, proceed in accordance with the Engine Fire During Start On Ground checklist. If an airplane fire is discovered on the ground or during takeoff, but prior to committed flight, the airplane should be stopped and evacuated as soon as practical. Engine fires originating in flight must be controlled as quickly as possible in an attempt to prevent major structural damage. Immediately shut off all fuel to the engine and shut down the engine. Close the cabin heat firewall shutoff control and forward side vents. To avoid drawing fire into the cabin, open the overhead vents, extend 20º to 30º flaps and slow down to 80-85 KIAS. This provides a positive cabin pressure in relation to the engine compartment. An engine restart should not be attempted. An open foul weather window produces a low pressure in the cabin. To avoid drawing the fire into the cabin, the foul weather window should be kept closed. A fire or smoke in the cabin should be controlled by identifying and shutting down the faulty system. Smoke may be removed by opening the cabin ventilation controls. When the smoke is intense, the pilot may choose to expel the smoke through the foul weather window. The foul weather window should be closed immediately if the fire becomes more intense when the window is opened. The initial indication of an electrical fire is usually the odor of burning insulation. The checklist for this problem should result in elimination of the fire. Supervan Systems, Ltd.

INADVERTENT FLIGHT INTO ICING CONDITIONS Intentional flight into known icing conditions is prohibited unless the complete flight into known icing equipment package is installed and operative and the airplane weight is 8750 pounds or less (cargo pod off) or 8550 pounds or less (cargo pod on). During instrument flights, however, icing conditions may be encountered inadvertently and, if the known icing equipment package is not completely functional, some corrective action will be required as shown in the checklist. Initiation of a climb is usually the best ice avoidance action to take; however, alternatives are descent to warmer air or course reversal. STATIC SOURCE BLOCKED If erroneous instrument readings are suspected due to water, ice, or other foreign matter in the pressure lines going to the left flight panel’s external static pressure source, the alternate static source valve should be pulled full on. A chart in Section 5 provides a correction which may be applied to the indicated airspeeds and altitudes resulting from inaccuracies in the alternate static source pressures. NOTE The altitude hold mode of the autopilot should be disengaged before actuating the alternate static source valve. SPINS Intentional Spins are prohibited in this airplane. Should an inadvertent spin occur, the following technique may be used: 1. RETARD THE POWER LEVER TO IDLE POSITION. 2. PLACE AILERONS IN NEUTRAL POSITION. 3. SIMULTANEOUSLY APPLY AND HOLD FULL RUDDER OPPOSITE TO THE DIRECTION OF ROTATION, AND MOVE THE CONTROL WHEEL BRISKLY FORWARD FAR ENOUGH TO BREAK THE STALL. Full down elevator may be required at aft center of gravity loadings to assure optimum recoveries. 4. HOLD THESE CONTROL INPUTS UNTIL ROTATION STOPS. Premature relaxation of the control inputs may extend the recovery. 5. AS ROTATION STOPS, NEUTRALIZE RUDDER AND MAKE A SMOOTH RECOVERY FROM THE RESULTING DIVE. NOTE If disorientation precludes a visual determination of the direction of rotation, the needle of the turn and bank indicator may be referred to for this information. NOTE Airspeed during the recovery of the airplane may exceed the respective flap setting VFE. When able, it is recommended that flaps be retracted during recovery to prevent this type of occurrence.

Also, the engine will eventually seize. Therefore, if the pilot elects to continue to operate the engine after loss of oil pressure, engine and propeller operation should be closely monitored for indication of the onset of propeller feathering or engine seizure and the engine failure checklist should be completed at that time. Operation of the engine at a reduced power setting (preferably at the minimum power required for the desired flight regime) will generally prolong the time to loss of engine/propeller thrust. Operation of the engine with the oil pressure in the yellow arc is not considered critical, but is a cause for concern and should be tolerated only for the completion of the flight. Continued monitoring of the oil pressure gage will provide an early indication of dropping oil pressure due to insufficient oil supply or a malfunctioning oil pump, and will give the pilot additional time to divert to a suitable emergency landing area with the engine operating. FUEL CONTROL UNIT MALFUNCTION If there is an indication of improper operation of the fuel control, when possible, check the handling of the aircraft by a simulated landing flare at a safe altitude before trying to land. If unusual drag is noted that cannot be eliminated by increasing power, it might be necessary to feather the engine and perform an Emergency Landing Without Engine Power. NON-RESPONSIVE POWER LEVER If during flight the power lever becomes unresponsive, it may be due to a frozen P2T2 sensor. The power lever response can be restored by utilizing the engine inlet anti-ice heat, which also heats the sensor. It is recommended to turn on the engine ignition during this operation to prevent an engine flameout. It may take several minutes for the power lever response to
