(6) Airplane De-fueling - Drain Valve Method The fastest and most efficient way to de-fuel the airplane is by removing the fuel drain valves. For maintenance practices pertinent to the fuel drain valves, see Chapter 28, Fuel. (Refer to 28-10) B. Engine Oil System The Teledyne Continental IO-550-N and TSIO-550-K engines use a wet sump pressurized lubrication system with an 8 quart (7.57L) capacity. A filler cap with integral dipstick is provided for determining the amount of oil in the crankcase. CAUTION: The oil level should be brought to full before each long flight. Never fly the airplane with less than 6 quarts of oil (5.7 Liters) in engine crankcase. Oil consumption tends to be higher during break-in periods on new engines. Under no circumstances should automotive oil be used, for such oils could cause engine damage. If oil system becomes contaminated, the complete oil system must be flushed and the oil cooler replaced. For the first 25 hours of operation (on a new or rebuilt engine) or until oil consumption stabilizes, use straight mineral oil conforming to SAE J1966. After oil consumption has stabilized, the mineral oil should be drained and an approved engine oil used. (Refer to ) Straight mineral oil conforming to MIL-C-6529 with a corrosion preventive compound added, can cause coking with extended use; therefore Cirrus Design does not recommend its use for break-in or post break-in. Oil conforming to MIL-P with a corrosion preventive compound added is recommended by TCM and Cirrus Design for indefinite storage. (Refer to 10-30) (1) Oil System Replenishing (a) Acquire necessary tools and equipment Approved Engine Oil (See Figure 1) See Approved Materials and Service Capacities Figure Lubrication (b) (c) Ensure airplane is sitting on a level surface with the engine off.

10 C. Hydraulic Brake System The main wheels have hydraulically operated, single-cylinder dual piston type disc brakes, individually activated by floor mounted toe pedals at both pilot stations. A parking brake mechanism holds induced hydraulic pressure on the disc brake for parking. The brake reservoir is located on the right side of the firewall in the engine compartment. The fluid level should be checked periodically and at every inspection and replenished when necessary. If entire system must be filled, fill with fluid under pressure from brake end of system. This will eliminate air in system. If system is low, the reason for fluid loss must be determined before continued operation of the aircraft. For additional brake information refer to Chapter 32. (Refer to 32-42) WARNING: Never service the hydraulic reservoir while the parking brake is activated. Fluid in the wheel cylinders may be under high pressure due to expansion. Therefore, be sure parking brake is released and wheel chocks are in place, prior to beginning hydraulic system servicing. If the brake pedal feels spongy, the complete brake system must be bled. If the system is low, the reason for fluid loss, must be determined before continued operation of the airplane. Any spilled brake fluid must be removed immediately as it will damage any painted surface upon contact. Remove any dirt on the brake fluid reservoir filler cap before opening. (1) Brake Fluid Replenishing (a) Acquire necessary tools and equipment.

Pump brake pedals to drain brake fluid from system.

11 D. Tires Always keep tires inflated to the rated pressure to ensure maximum service and to reduce damage when landing on stones with sharp edges. When adjusting tire pressure, inspect the tires for any signs of abnormal wear, cuts, or bruises. If airplane tires should ever freeze to ground surface, use hot air or water to free tires before attempting to move airplane. For additional tire and wheel information refer to Chapter 32. (Refer to 32-41) (1) Tire Air Pressure Replenishing (a) Acquire necessary tools, equipment, and supplies. Compressed Air Supply - Any Source Adding air pressure to tires. Air Pressure Gage - Any Source Checking tire pressure. Wheel Chocks - Any Source Securing airplane. CAUTION: The following procedure must be performed in calm, warm weather, with the airplane sitting on a smooth and level surface. Always check air pressure using an accurate gage. Always consider load factor and ambient temperature when checking air pressure. Air pressure will increase when the tire is subjected to a load and when the temperature increases. Whenever an air pressure specification is called out, but not defined as loaded or unloaded, it should be considered as unloaded. Always service tires in a warm environment, this will keep the valve stem from freezing and eliminate the possibility of leaks through the valve core. After inspecting or adjusting tire pressure, always inspect valve core for leaks before reinstalling valve cap. Always install a valve cap to prevent contaminates from entering valve core. (b) Set parking brake and place wheel chocks into position. (c) Serials thru , 22T-0001 thru 22T-0441: Remove access plug from wheel pant.

12 E. Battery System Two batteries are used for power storage on the airplane. Serials w/ TCM Battery: Battery 1 is located in the engine compartment and is the only battery requiring electrolyte maintenance. Serials w/ Concorde Battery: Battery 1 is located in the engine compartment and is considered a sealed, maintenance free battery. Battery 2 is located aft of bulkhead 222 and is considered a sealed, maintenance free battery. Visual inspection of battery 1 should be done every month or 25 flight hours until experience indicates a longer inspection interval. Check the battery, container, cover, and connections for distortion or damage. Proper battery charging procedures for both types of batteries, along with other pertinent information can be found in Chapter 24. (Refer to 24-30) WARNING: Always wear a face shield and remove all jewelry before servicing the battery. Metal objects may fuse to electrical connections and cause severe burns. Neutralize electrolyte spills with a solution of baking soda and water, then rinse with clean water. Do not add acid to battery unless electrolyte has been lost by spillage. When it is necessary to add acid, the battery should be fully charged, on charge, and gassing freely. Specific gravity may then be adjusted by adding acid or distilled water, or drawing off electrolyte. (1) Battery 1 Electrolyte Level Check - Serials w/ TCM Battery (a) Remove battery 1. (Refer to 24-30) (b) Remove battery cell caps. (c) Visually inspect battery cells for proper electrolyte level. As an example, a warm battery condition would exist just after a bench charge or following a flight of ninety minutes or more. 1 If battery is warm and in a good state of charge, verify electrolyte level just touches or is slightly short of level indicator eyelet. 2 At all other times, verify electrolyte level is approximately 1/4 inch (6.4 mm) above the plates. (d) If a battery cell is low, add distilled water to obtain proper electrolyte level and charge battery to mix the electrolyte. (Refer to 24-30) (e) Perform Battery 1 Electrolyte Specific Gravity Check. (Refer to ) (f) Install battery cell caps. (g) Install battery 1. (Refer to 24-30) (2) Battery 1 Electrolyte Specific Gravity Check - Serials w/ TCM Battery Electrolyte is a diluted solution of sulfuric acid and distilled water with a specific gravity of Pure distilled water has a specific gravity of and concentrated sulfuric acid has a specific gravity of The specific gravity of the electrolyte in a battery cell is a good index to the state of charge in the cell, due to the fact that as the battery is discharged, the acid in the electrolyte is used up. A specific gravity reading from to usually indicates a fully charged cell. If the reading is from to 1.260, the charge is considered low. It must be noted that the specific gravity reading is not always an indication of the state of charge in a cell. If electrolyte is removed from a discharged cell and replaced with an electrolyte of high Page Jun 2010

13 specific gravity, the cell will still be in a discharged condition even though the hydrometer indicates a full charge reading. Temperature must be considered when measuring specific gravity. Hydrometer readings will vary as the temperature goes above or below 80 F (26.70 C). The standard temperature used in rating lead acid battery performance is 77 F (25 C). (a) Acquire necessary tools and equipment. Hydrometer FR-1 Teledyne Continental Measure specific gravity. Small Plastic Syringe - Any Source Replenish electrolyte. Distilled Water - Any Source Replenish electrolyte. Bicarbonate of Soda (baking soda) - Any Source Neutralize electrolyte. Rubber Apron and Gloves - Any Source Prevent electrolyte exposure. Face Shield and Goggles - Any Source Prevent electrolyte exposure. (b) Remove battery 1. (Refer to 24-30) (c) Remove battery cell cap. If electrolyte level is too low for accurate hydrometer readings, add just enough distilled water to cover the plates. Charge battery to mix the electrolyte. Continue charging until the voltage and specific gravity readings are constant over three readings taken at 1/2 hour intervals. (d) (e) (f) Draw electrolyte into hydrometer. Verify specific gravity of electrolyte measures or above. Return electrolyte to same cell from which electrolyte was removed. To prevent contamination between cells, immediately install cell caps to original location after testing specific gravity. (g) Install battery cell cap. Adjust electrolyte level at the end of a charge because the level will rise from acid coming back into the electrolyte mix, normal gassing, and expansion from the temperature rise. (h) If necessary, adjust specific gravity of battery cell by adding distilled water or drawing off electrolyte. (i) Repeat for remaining battery cells. (j) Install battery 1.
