B. Engine Oil System

The Teledyne Continental IO-550-N engine uses a wet sump pressurized lubrication system with an 8 quart (7.57 L) 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 auto-motive oil be used, for such oils could cause engine damage. If oil system becomes con-taminated, 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 12-10)

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 recom-mend its use for break-in or post break-in. Oil conforming to MIL-P-46002 with a corro-sion preventive compound added is recommended by TCM and Cirrus Design for indefinite storage. (Refer to 10-30)

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 brake system is filled with MIL-H-5606 hydraulic brake fluid. The fluid level should be checked periodically and at every inspection and replenished when neces-sary. 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 deter-mined 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.

(b) Remove upper engine cowling. (Refer to 71-10)(c) Remove any dirt from hydraulic brake fluid reservoir before opening filler cap.(d) Remove filler cap and add hydraulic brake fluid to reservoir until full.(e) Use syringe to remove approximately 0.24 oz (7 ml) of hydraulic fluid from brake reservoir.(f) Install filler cap.(g) Inspect entire brake system for leakage or problems. (h) Install engine cowling. (Refer to 71-10)

(2) Brake Fluid Draining(a) Acquire necessary tools, equipment, and supplies.

(b) Place drain pans under LH and RH brake bleeder fitting on brake assemblies.(c) Remove bleeder caps and screws from bleeder fittings.(d) Pump brake pedals to drain brake fluid from system.

Syringe - Any Source Remove hydraulic fluid.


Drain Pans - Any Source Fluid recovery.


EFFECTIVITY:

D. Tires

The nose tire uses a 5.00 - 5 wheel with a 5.00 x 5, six-ply rated tire with tube. The main landing gear uses 15 x 6.00 X 6 wheels with 15 x 6.00 - 6, six-ply rated tires with tubes. 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.

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.

Note: 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) Remove access plug from wheel pant.(d) Release parking brake and remove wheel chocks.(e) Move airplane until valve stem is accessible through wheel pant inspection hole.(f) Place wheel chocks into position.(g) Remove valve cap.(h) Using an accurate gage, verify tire pressure. (See Figure 12-101)(i) Add compressed air to tire as required to obtain recommended pressure. If tire is over

inflated, push in on valve core and release air to obtain recommended pressure.(j) Inspect valve core for leaking.(k) Install valve cap.(l) Install access plug to wheel pant.(m) Reset parking brake and place wheel chocks into position.

E. Battery System

Two batteries are used for power storage on the airplane. Battery 1 is located in the engine compart-ment and is the only battery requiring electrolyte maintenance. 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 dam-age. Proper battery charging procedures for both types of batteries, along with other pertinent informa-tion 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. Neutral-ize 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 gas-sing freely. Specific gravity may then be adjusted by adding acid or distilled water, or drawing off electrolyte.

(1) Battery 1 Electrolyte Level Check(a) Remove battery 1. (Refer to 24-30)(b) Remove battery cell caps.(c) Visually inspect battery cells for proper electrolyte level.

Note: 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 bat-tery to mix the electrolyte. (Refer to 24-30)

(e) Perform Battery 1 Electrolyte Specific Gravity Check. (Refer to 12-10)(f) Install battery cell caps.(g) Install battery 1. (Refer to 24-30)

(2) Battery 1 Electrolyte Specific Gravity CheckElectrolyte is a diluted solution of sulfuric acid and distilled water with a specific gravity of 1.285. Pure distilled water has a specific gravity of 1.000 and concentrated sulfuric acid has a specific gravity of 1.835.

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 spe-cific gravity reading from 1.285 to 1.295 usually indicates a fully charged cell. If the reading is from 1.220 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 specific gravity, the cell will still be in a discharged condition even though the hydrometer indi-cates a full charge reading.


EFFECTIVITY:

Note: Temperature must be considered when measuring specific gravity. Hydrom-eter readings will vary as the temperature goes above or below 80° F (26.70° C). The standard temperature used in rating lead acid battery per-formance is 77° F (25° C).

(a) Acquire necessary tools and equipment.

(b) Remove battery 1. (Refer to 24-30)(c) Remove battery cell cap.

Note: If electrolyte level is too low for accurate hydrometer readings, add just enough distilled water to cover the plates. Charge battery to mix the electro-lyte. Continue charging until the voltage and specific gravity readings are constant over three readings taken at 1/2 hour intervals.

(d) Draw electrolyte into hydrometer.(e) Verify specific gravity of electrolyte measures 1.225 or above.(f) Return electrolyte to same cell from which electrolyte was removed.

Note: To prevent contamination between cells, immediately install cell caps to original location after testing specific gravity.

(g) Install battery cell cap.

Note: 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 expan-sion 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. (Refer to 24-30)

(Refer to 06-00)2 Disconnect system supply line from horizontal proportioning unit inlet port.3 Connect in-line pressure gauge to horizontal proportioning unit inlet port.4 Connect TKS cart 5/16 inch supply line to in-line pressure gauge.

(i) Serials 2438 & subs: Connect TKS cart to horizontal porous panels.1 Remove empennage access panel RE3. (Refer to 06-00)2 Remove cable tie securing coupler assemblies to fuselage.3 Disconnect system supply line from each coupler assembly.4 Connect in-line pressure gauge to each coupler assembly.5 Connect TKS cart 5/16 inch supply line to each in-line pressure gauge.

(j) Verify TKS cart control settings.1 Set water regulator to CLOSED position.2 Set air regulator to CLOSED position.3 Set selector valve to TKS FLUID position.4 Set output selector to 5/16 position.5 Set feed valve position to DOWN - SINGLE FEED position.

(k) Initiate fluid flow.

CAUTION: Ensure pressure does not exceed 150 psi (1034 kPa).

Do not allow pressure vessel to run dry. If vessel runs dry, isolate andpurge panel individually at 70 psi (483 kPa) or higher for at least 10minutes.

1 At each pressure gauge, open shutoff valve.2 Rotate air regulator knob clockwise to increase pressure by 5 psi (34.5 kPa) every 5

seconds up to 60 psi (414 kPa).

Note: If unable to obtain minimum required pressure on both panels, isolate and purge one panel at a time.


EFFECTIVITY:

3 Continue to adjust air pressure on TKS cart until each in-line pressure gauge indi-cates at least 60 psi for wing panels and 65 psi for horizontal panels.

4 Start timer.(l) Inspect de-icing fluid flow from porous panel.

1 Wipe leading edge with high density sponge as flow becomes evident.2 Inspect flow distribution along entire active area of porous panel.3 Allow panel to flow a minimum of 5 minutes and for as long as 15 minutes.

Note: It is permissible to have a dry area no larger than two rows by two inches (5 cm) long.

4 Inspect porous panel for consistent and even distribution along entire length of lead-ing edge, ensuring all laser-drilled holes are wetting out.

5 Visually inspect porous panel surface to verify that air is being purged in the form of very small air bubbles. As the membrane becomes saturated, the frequency of bub-bles will reduce dramatically. Observe initial frequency of air bubbles, and verify that the frequency is drastically reduced or eliminated before 15 minutes has elapsed.

(m) For wing porous panels: Porous panel flow is adequate if flow of each panel is consistent along entire length of panel, and purging of air bubbles is drastically reduced by the time 15 minutes has elapsed. If wing porous panel flow is inadequate, perform the following procedure.1 Isolate porous panel by using a shutoff valve to open and close lines as needed.2 Fill pressure vessel 1/2 full with approved de-icing fluid.

CAUTION: Ensure pressure does not exceed 150 psi (1034 kPa).

Do not allow pressure vessel to run dry. If vessel runs dry, isolate andpurge panel individually at 70 psi (483 kPa) or higher for at least 10minutes.

3 Rotate air regulator knob clockwise to increase pressure by 5 psi (34.5 kPa) every 5 seconds up to 70 psi (483 kPa).

4 Continue to adjust air pressure on TKS cart until in-line pressure gauge indicates at least 70 psi (483 kPa).

5 Start timer.6 Inspect de-icing fluid flow from porous panel as described above. (Refer to 12-10)7 If flow is still inadequate, replace the porous panel. (Refer to 30-10)

(n) For horizontal porous panels: Porous panel flow is adequate if flow of each panel is con-sistent along entire length of panel, and purging of air bubbles is drastically reduced by the time 15 minutes has elapsed. If horizontal porous panel flow is inadequate, replace the porous panel. (Refer to 30-10)

(o) Shutdown TKS cart.1 At each pressure gauge, close shutoff valve.2 Rotate air regulator knob counterclockwise to close.3 Pull up on pressure vessel safety valve to relieve pressure.4 Disconnect air source from TKS cart.

Note: Use fresh de-icing fluid if there is evidence of contamination.

5 Replenish pressure vessel with de-icing fluid collected from 5 gallon buckets.
