The airplane can also be towed by the nose wheel held on the platform of an electric towbarless tow vehicle. (2) The airplane can be towed with a f at tire, but it is not recommended. The airplane can be moved from an active runway or taxiway with a f at tire. Tow the airplane forward a minimum distance to clear the runway or taxiway and do not use sudden turns. The tire will be unserviceable, and the wheel must be examined. Refer to the Supplier's Overhaul Manual given in the Introduction, Supplier Publication List. B. Taxiing. (1) The airplane can be taxied on a hard surface, gravel, or sod taxiway and runway. The airplane has a nose wheel steering system. During taxi, the rudder pedal movement operates the nose steering system. CAUTION: Do not use too much engine thrust during a taxi with a f at tire. Monitor the inter-turbine temperature (ITT) indicator for engine over temperature. (2) It is not recommended to taxi the airplane with a f at tire. Under emergency conditions, the airplane can be taxied a short distance to clear the active runway or taxiway. Cessna Aircraft Company Aug 1/2010

2 1. General TOWING - MAINTENANCE PRACTICES A. The airplane can be towed with a yoke-type towbar attached to the nose wheel. The airplane also can be towed by the nose wheel held on the platform of an electric towbarless tow vehicle. (Refer to Figure 201). CAUTION: Do not turn the nose gear more than it's turn limit. If you do, the nose gear turn angle will break the stop bolts on the top of the trunnion. (1) When the airplane is towed, the vehicle operator must make sure that they do not turn the nose gear more than it's limits. (2) Steering is done with the towbar or the towbarless vehicle when the airplane is towed. B. An approved person must be in the airplane during the tow operation to be prepared for dangerous conditions. (1) Put personnel to walk with the wing and/or the tail to make sure that there is suff cient clearance between the airplane and adjacent equipment and structures. 2. Tools and Equipment A. For a list of tools and equipment, refer to Towing and Taxiing - General. 3. Nose Landing Gear Towing A. Tow the Airplane (Refer to Figure 202). CAUTION: Make sure that there is suff cient weight forward of the center of gravity. Add weight or remove weight as necessary to adjust the center of gravity for interior conf gurations or an airplane without fuel. CAUTION: Do not turn the nose landing gear more than an angle of 75 degrees to the right or to the left side of center. A nose gear that goes beyond the tow stop (75 degree limit) will break the stop bolts on the top of the trunnion and cause damage to the nosewheel steering system. CAUTION: Do not move the airplane in 15 minutes or less after the standby attitude indicator gyro has stopped. This can cause damage to the gyro. CAUTION: Make sure that the recommended towbar is used. Make sure that the towbar is in good condition, inspect the towbar at intervals for cracks and condition. CAUTION: Do not use the nose landing gear to release the airplane if it becomes caught in soft dirt. Contact Citation Customer Service. CAUTION: Make sure that you disengage the rudder control lock before you tow the airplane. If you do not disengage it, damage to the airplane can occur. (1) Position the towbar at the nosewheel and insert the towbar into the nosewheel axle. (2) Engage the towbar locking handle. (3) Connect the towbar to the tow vehicle.

5 (4) Put an approved person in the pilot's seat. NOTE: The airplane can be towed with the elevator and aileron control locks installed in the control column. (5) Disengage the rudder control lock. (6) Disengage the parking brake. (7) Make sure that the wheel chocks, static ground cables, and mooring ropes are removed. (8) Put personnel at the wing and/or the tail to walk and to look for suff cient clearance between the airplane and adjacent equipment or structures. (9) Tow the airplane and make smooth starts and stops during the procedure. (10) When the tow operation is complete, make sure that you do as follows: (a) Put the nosewheel to the center position. (b) Engage the parking brake. (c) If necessary, install the elevator and aileron control locks. (d) Put the chocks in position at the wheels. (e) Connect the static ground cables. (f) Engage the rudder control lock. (g) Remove the towbar from the airplane. B. Use the Electric Vehicle to Tow (Without a Towbar). CAUTION: Make sure that there is suff cient weight forward of the center of gravity. Add weight or remove weight as necessary to adjust the center of gravity for interior conf gurations or an airplane without fuel. CAUTION: Do not turn the nose landing gear more than an angle of 75 degrees to the right or to the left side of center. A nose gear that goes beyond the tow stop (75 degree limit) will break the stop bolts on the top of the trunnion and cause damage to the nosewheel steering system. CAUTION: Do not move the airplane in 15 minutes or less after the standby attitude indicator gyro has stopped. This can cause damage to the gyro. CAUTION: Make sure the recommended electric towbarless vehicle is used. CAUTION: Make sure that the electric towbarless vehicle is not more than pounds ( kg). CAUTION: Make sure that you disengage the rudder control lock before you tow the airplane. If you do not disengage it, damage to the airplane can occur. (1) Wind a winch-strap around the nose landing gear strut immediately above the fork and the electric towbarless vehicle. (2) Put an approved person in the pilot's seat. NOTE: The airplane can be towed with the elevator and aileron control locks installed in the control column. (3) Disengage the rudder control lock. (4) Disengage the parking brake. (5) Make sure that the wheel chocks, static ground cables, and mooring ropes are removed.

6 (6) Put personnel at the wing and/or the tail to walk and to look for suff cient clearance between the airplane and adjacent equipment or structures. CAUTION: Make sure that the tail stand is removed before you lift the nose. If it is not removed, the tail stand can hit the ground and cause damage to the airplane. (7) Lift the nose landing gear into the electric towbarless tow vehicle. (8) Tow the airplane and make smooth starts and stops during the procedure. (9) When the tow operation is complete, make sure that you do as follows: (a) Put the nose wheel to the center position. (b) Engage the parking brake. (c) If necessary, engage the control locks. (d) Put the chocks in position at the wheels. (e) Connect the static ground cables. (f) Engage the rudder control lock. (g) Remove the towbar from the airplane.

7 1. General TAXIING - MAINTENANCE PRACTICES A. The airplane is controlled with engine thrust, rudder pedal steering, and brakes during the taxi procedure. The taxi procedure can be done with one or both engines. B. Taxi Safety Precautions. (1) Personnel that taxi an airplane must be familiar with the airplane and the taxi turn limits. Refer to Figure 201. (2) Make sure that the hydraulic system and the brakes are in a serviceable condition. (3) Use only the necessary engine thrust to start movement and to keep the approximate taxi speed. (4) Do not use the brakes continuously to keep the correct speed. Adjust the engines as necessary. (5) Make sure that the taxi route is clear and free of all blockage, such as maintenance stands and vehicles. (6) Use an observer(s) to make sure that there is wing tip clearance. (7) On surfaces with ice, when the nosewheel is turned but has no result, do not let the nosewheel be turned left or right. Damage to the nose gear can result if a dry area is hit with the wheel in a turned position. 2. Taxi the Airplane A. The maximum steering angle when the rudder pedals are used is 20 degrees left and right of center. When the rudder pedals and left/right braking are used together, the maximum angle is limited to 75 degrees left and right of center. Steering during the taxi operation is done by the rudder pedals and left/right braking. Two-engine operation is recommended during taxi, due to the high thrust necessary to move the airplane from the parking area. B. Prepare the Airplane. (1) Clean the area around the airplane. (2) Examine the main wheels and remove the static ground cables and the tail stand. (3) Make sure that the fuel level in the wings is balanced as much as possible. (4) Close all of the access and the baggage doors. (5) Disconnect the ground cable. C. Taxi the Airplane (Refer to Figure 202). (1) Put two personnel in the f ight compartment, one in the pilot's seat to taxi the airplane, and one in the copilot's seat to help and to be an observer. (2) Engage the parking brake. WARNING: Make sure that personnel and equipment are clear of the engine inlet and the exhaust areas. (3) Start the engines. Refer to the Model 510 FAA Approved Airplane Flight Manual. (4) Remove the wheel chocks. (5) Release the parking brake. (6) Make sure that the ground power unit is disconnected. (7) Make sure that the taxi personnel know where the airplane will be moved to and what they need to do. (8) Make sure that personnel are clear of the engine inlet and the exhaust areas. (9) Use only suff cient thrust to the engines to start to move the airplane. Move the airplane forward before it is turned. (10) Do not apply the brakes while the airplane is taxied, decrease the engine thrust to decrease the taxi speed. (11) Use the brakes to control the taxi speed, but only use the brakes for a very small quantity of time. (12) Control the airplane using the rudder pedals. NOTE: Nose gear steering is operated with the rudder pedals. (13) Put personnel at each wing tip to make sure that the wings do not hit any object.
