BEECHCRAFT KING AIR 200 & 300 SERIES SADDLE TANKS ICA MANUAL

the saddle tank goes through the back of the wheel well, runs along the rear spar, and enters at the back of the auxiliary fuel tank. Ventilation for the saddle tank is provided by the existing fuel vent lines, which are split between the inboard and outboard wing in the wheel well and routed up, through the wing, and into the saddle tank. Placards also identify each of the six added tank and vent drain ports. BEECHCRAFT KING AIR 200 & 300 SERIES SADDLE TANKS ICA MANUAL PAGE 2 MANUAL No. 26012-30 INTRODUCTION REV. 3, FEB-2019 The saddle tanks each include five optical fuel level sensors connected to an indicator unit mounted to the pilot’s side wall. The indicator has five LED indicators for each tank, corresponding to an individual level sensor. When fuel is at or above the indicated level, the LED illuminates green. As fuel drops below each level sensor, the LED extinguishes with the exception of the last LED, which changes from green to amber. Refer to the individual chapters in this manual for additional details and illustrations of saddle tank components and systems.

REPLENISHING FUEL SYSTEM SERVICING 5. FILLING THE TANKS Saddle Tanks 1) Fill the saddle tanks last. The saddle tank fuel caps are located on top of the tank, behind the nacelles. Verify both main & auxiliary tanks are full before filling the saddle tanks. 2) Do not fill the saddle tank beyond its specified capacity or above the bottom of the standpipe in the filler port. 3) With fuel in the saddle tanks, do not open the auxiliary fuel cap. If the auxiliary fuel cap is removed, the addition of fuel in the saddle tank may force fuel to escape past the auxiliary tank anti-siphon valve. 6. DRAINING THE FUEL SYSTEM Saddle Tanks The saddle tanks will drain automatically through the auxiliary fuel tanks. An alternate method is to open the saddle tank sump drain valve located at the back of the 95-gallon tank. For the 60-gallon and 36- gallon tanks, the sump drain valve is located below the wing and behind the rear spar at the inboard side of the tank. LANDING GEAR SERVICING 2. LANDING GEAR Shock Absorbers / Strut Servicing Include full fuel in the saddle tanks when checking and adjusting the nose strut and main strut extension.

Each compartment has six D-rings that can be used to secure cargo. The compartment may include a liner for the floor and possibly the sides, door, and forward bulkhead. NOTE: The liner type and material is a customer option. Both the 60-gallon and 36-gallon tanks include a fire barrier between the storage compartment and the fuel tank. The saddle tank has a layer of fire-proof ceramic paper between the forward storage compartment bulkhead (also called the false bulkhead) and the fuel tank bulkhead. Some saddle tanks include a layer of ceramic paper under the liner on the floor and bulkhead. The following table identifies fire barrier materials. There is one moisture drain hole in the compartment floor, inboard side, between the storage compartment and fuel tank bulkheads. There are two drain holes in the aft end of the saddle tank below the door latches. These holes should be kept open to allow for moisture to escape and ventilation. STORAGE COMPARTMENT – MAINTENANCE PRACTICES MOISTURE DRAIN INSPECTION Visually inspect the moisture drains as specified by Chapter 5 of this manual. NOTE: For 36-gal. saddle tanks, the drain between storage compartment and fuel tank bulkheads is not accessible for a direct visual inspection when installed. Check this drain at the same time as the fuel level sensor when the inspection panel on the false bulkhead is open (see Chapter 28 of this manual). A light and mirror can be used to verify the drain hole is open. If fuel or a steady stream of moisture is coming from the drain between the storage compartment and fuel tank bulkheads, then remove the false bulkhead using the procedure below and inspect the area. Repair saddle tank fuel leaks as specified in Chapter 28 of this manual. Replace the ceramic paper according to this chapter if: a. Soaked with fuel. b. Damaged or unable to dry. Remove any blockage obstructing a drain hole. Check for signs of corrosion. Refer to the Beechcraft AMM for corrosion treatment procedures. FALSE BULKHEAD REMOVAL AND INSTALLATION a.

There are three sizes of saddle tanks available that add a total of 72, 120, or 190 gallons of usable fuel capacity to the existing fuel system. Refer to the fuel system diagrams in Figures 1A thru 1C. The functions of the main, auxiliary, and nacelle fuel systems are unchanged by the addition of the saddle tanks. The saddle fuel tanks are mounted behind each engine nacelle to the upper surface of the wing. Five ¼-inch (AN4) bolts hold each tank to the wing. Also, twelve AN3 bolts attach the front of the tank to the engine nacelle structure. An aluminum fairing between the engine nacelle and the front of the tank provides a smooth transition for air flow around the saddle tank. Each tank has its own filler opening located on top of the saddle tank. The main fuel line from the saddle tank goes through the back of the wheel well, runs along the rear spar, and enters at the back of the auxiliary fuel tank as shown in Figure 2. Each tank has a sump drain, a main fuel line low-point drain, and a vent line low- point drain. Ventilation for the saddle tank is provided by the existing vent system. The vent line running from the auxiliary tank to the outer wing is modified and routed up, through the wing and into the saddle tank as shown in Figure 3A. The original ventilation system connects the existing nacelle vent line to the inboard saddle tank vent line. Aircraft modified after November 2016 or in accordance with CTA Service Bulletin (SB) no. 045-2017-01 have a revised ventilation system. The revised ventilation system modifies the existing nacelle tank vent lines by removing a check valve and routing a new vent line directly from the top of the nacelle to the saddle tank as shown in Figure 3B. The revised ventilation system also eliminates the inboard saddle tank vent standpipe and the existing float check valve in the outboard vent line. Model B300C serial no. FM-3 is equipped with an alternate ventilation system that connects the existing nacelle vent line directly to the saddle tank rather than the inboard saddle tank vent line per the original ventilation system. The 36-gallon and 60-gallon saddle tanks have a separate storage compartment located behind the fuel storage compartment. See Chapter 25 for information on the storage compartment interior. See Chapter 52 for a description of the storage compartment door and maintenance details. For King Air models 200T, 200CT, A200CT, B200CT, and B200T, the 53-gallon wing-tip tanks may not be used with the saddle tanks. With the saddle tanks installed, the airplane is configured with Beechcraft’s optional wing tips.

The optical switches use infra-red light to determine whether the sensor is submerged in fuel or exposed to air. The fuel level indicator has a left and right column of green LEDs that are labeled by the quantity of fuel corresponding to the level of the switch in the tank. See the FUEL LEVEL INDICATING SYSTEM FUNCTIONAL TEST section below for the fuel level markings according to each size of saddle tank. When fuel is at or above the indicated level, the LED illuminates green. As fuel drops below each level sensor, the LED extinguishes with the exception of the last LED. The bottom LED is a bi-color LED that stays green when the switch is submerged in fuel then changes to amber when the tank is empty. SADDLE TANK FUEL INDICATING SYSTEM – TROUBLESHOOTING If the fuel level indicator is not working properly, consult Chart 2 below for possible problem indicators, causes and solutions Chart 2. Troubleshooting Fuel Level Indicating System Indication Possible Cause Remarks 1) Fuel level indicator LEDs not illuminated. a) Aircraft power is OFF. b) Fuel panel circuit breaker is pulled (OFF). c) Blown fuse in indicator assembly. a) Turn on main battery power. b) Depress circuit breaker. c) Replace fuse. 2) Individual LED(s) not illuminated. a) Fuel level in tank is below level switch. b) Faulty level switch. c) Faulty LED. a) Condition is normal. b) Replace level switch. c) Replace indicator assembly. 3) “0” quantity LED is amber with fuel in saddle tank. Faulty level switch. Replace level switch. SADDLE TANK FUEL INDICATING SYSTEM – MAINTENANCE PRACTICES FUEL LEVEL INDICATING SYSTEM FUNCTIONAL TEST Since the fuel level indicator and optical switches are activated every time the ship’s power is turned on, a functional test is made every time the fuel tank is filled. To determine if the switches are functioning properly, observe the fuel level indicator when the tank is empty or is being filled. Charts 3 thru 5 below show the LEDs illuminated at by fuel level for each type of saddle tank. When a saddle tank is empty, only the “0” quantity LED is illuminated (amber). As the saddle tank is filled, the “0” quantity LED changes from amber to green and each next higher LED will illuminate green as the fuel level submerges the corresponding level switch. If an LED does not illuminate as indicated in Charts 3 thru 5 for the specified fuel level in the saddle tank, refer to Chart 2 for troubleshooting. BEECHCRAFT KING AIR 200 & 300 SERIES SADDLE TANKS ICA MANUAL PAGE 28.28 MANUAL No. 26012-30 CHAPTER 28 REV. 2, JUN-2018 NOTE: Before performing the functional test, fill the auxiliary fuel tank. NOTE: When performing the functional test, the fuel quantity required to illuminate the indicator LED will depend on the orientation of the airplane. To check the accuracy of the fuel level indication, the functional test must be done on a level surface with the airplane level. See Beechcraft AMM for procedures to level the airplane.
