I. Introduction and Description
N604CM Pilot Operating Handbook 3
The Sonex is a high-performance, homebuilt aircraft. Its compact external size and extremely efficient design results in superb performance and excellent fuel economy using a relatively low power engine, outperforming many general aviation aircraft. Typical cruise speed is 150 mph, burning approximately 5 gallons per hour, yielding fuel economy in excess of 30 miles per gallon.
The structure of the Sonex is almost entirely 6061T6 aluminum, yielding a design that is easy to construct, conventional to maintain, and resistant the effects of weather and corrosion.
Power is supplied by a Jabiru 3300 6-cylinder aircraft engine, produced in Australia by Jabiru Aircraft Pty, Ltd. This engine is largely CNC-machined from billet aluminum, and features a forged steel crankshaft, dual spark plugs per cylinder, 2 independent ignition systems, adjustable mixture control, alternator, and electric starter. It is a lightweight, modern, reliable aircraft engine that is easily maintained. The Jabiru is fitted with an AeroInjector, offering superior operation, power, and efficiency in all modes of operation.
Flight Instruments and Avionics
The Sonex was designed as a VFR sport plane, and the installed flight instruments reflect this mission. All primary flight instruments, engine monitoring instruments and navigation instruments are provided by a 7” display Dynon “Skyview” system. An Air Data/Attitude/Heading Reference System (ADAHRS) provides airspeed, altitude, rate of climb, heading, and attitude information; an Engine Monitoring System (EMS) module provide monitoring of all engine temperatures, pressures, fuel flow and RPM; an external Global Positioning System (GPS) receiver provides moving
N604CM Pilot Operating Handbook 4
map navigation and location information; a Dynon remote-mounted transponder unit provides Mode C/S transponder functionality, controlled through the main Skyview display.
Two-way radio communication is provided separately from the Skyview system by an MGL “V6” VHF Airband Communications Radio (COMM), which also provides a voice-activated (VOX) cockpit intercom for the aircraft occupants. The V6 radio also provides auxiliary audio input and output through 1/8” headphone plugs. Auxiliary input provides for music and entertainment sources, and auxiliary output provides for recording cockpit intercom and COMM radio audio signals. Auxiliary audio input automatically fades and mutes during incoming radio transmissions.
Flight Controls
Pitch and roll capability is accomplished by conventional dual control sticks located at each seat. Pitch control is provided by elevators mounted on the horizontal stabilizer. Roll control is accomplished by ailerons on the outboard portion of the main wing. N604CM is equipped with the optional large “acro” ailerons, providing excellent and responsive roll authority. Yaw control is provided by a rudder mounted on the vertical stabilizer, and is actuated by conventional rudder pedals and control cables. All other flight controls including the flaps are pushrod actuated.
Pitch Trim System
An in-flight cockpit adjustable pitch trim system is provided. A lever mounted on the left cockpit sidewall adjusts a movable control tab mounted on the left elevator half. The trim system is completely independent of the normal pitch
N604CM Pilot Operating Handbook 5
control system, thus providing back-up pitch control system in the event of a primary control problem. The primary pitch control system (i.e. the stick) can override any position of the trim system.
Engine Controls
The throttle, identified with a black T-handle, is located in the lower portion of the center instrument panel. It is a quadrant style control, in which the lever is rotated forward (towards to nose) to open the throttle (increasing power) and rearward to close the throttle (decreasing power). A friction control knob is located on the right side of the quadrant to set the desired resistance to movement of the lever. A button-locking mixture control is located to the right of the throttle, and is identified by a red handle. Carburetor heat is not installed, nor is it required by the AeroInjector.
Landing Gear
The main landing gear legs are 1-1/8” titanium rod, mounted directly into the engine mount. Due to the mechanical properties of titanium, the Sonex gear is extremely robust, yet forgiving. The titanium gear legs will bend gently under landing loads, and then rebound slowly without springing the aircraft back into the air. The tail wheel is mounted to a 5/8” titanium rod. Steering is accomplished through a direct linkage to the rudder, resulting in very accurate and positive directional control while taxiing, and during takeoff and landing.
Brakes
N604CM Pilot Operating Handbook 6
The braking system consists of hydraulic disc brakes on each main wheel. Braking action is non-differential, actuated by a single aluminum lever in the center control console between the occupants. Brakes are applied by pulling the lever rearward. A parking brake detent locks the brake lever in the rear, fully-engaged position. Brakes set to the parking detent are sufficient to prevent the aircraft’s movement at all throttle settings including full static rpm (i.e. WOT). Care must be used in brake application during high-speed taxi (30+ mph) to avoid flipping the aircraft over on its back.
Fuel System
A single 16-gallon molded polyethylene main fuel tank is located just aft of the firewall above the occupant’s legs. Unusable fuel quantity is less than ¼ gallon. The fuel filler cap is located on the upper forward fuselage, accessible from the outside of the aircraft through the fuel filler door in the cowling. Approved fuels include 91 octane (or higher) automotive fuel and 100LL aviation fuel. Fuel is delivered by gravity feed, and the engine-driven fuel pump has been removed. A fuel shutoff valve is located inside the cockpit at the tank outlet, consisting of a ¼ turn ball valve. The fuel valve is closed by pulling the fuel shutoff valve control cable rearward. A machined billet-aluminum fuel filter is located on the engine side of the firewall immediately after the fuel line passes through the firewall. The fuel filter captures particles down to 40 microns on a metal mesh screen, and is easily disassembled and cleaned during servicing.
Fuel Flow Meter
N604CM Pilot Operating Handbook 7
An FT-60 “Red Cube” fuel flow meter is installed inside the cockpit just after the fuel shutoff valve to measure the consumption of fuel. No direct measurement of fuel quantity is available while in flight, but accurate fuel totalizer information is provided by the Skyview EMS, including fuel used, fuel remaining, and time/range to fuel exhaustion. Fuel quantity must be confirmed visually and manually input into the Skyview system at the beginning of each flight. Auxiliary Fuel Tank
The main fuel tank has provisions for an auxiliary tank to be optionally connected. The upper 1/8 NPT fitting molded into the main tank serves as the aux fuel inlet, and contains a checkvalve, hose, and quick disconnect assembly. This allows a portable auxiliary fuel tank to be placed in the cabin (PAX seat or baggage compartment) and connected to the main fuel tank. The checkvalve prevents fuel from escaping the main tank at the aux fuel inlet. CG effects and baggage compartment weight limits must be considered when using an aux fuel tank.
Smoke System
The aircraft is equipped with an AeroConversions Smoke System. Smoke fluid is contained in a welded aluminum tank attached to the engine-side of the firewall. The approximate capacity of the tank is 4 quarts. The smoke system pumps smoke fluid into both 3-in-1 exhaust collector pipes. Control of the smoke pump is provided by a panel-mounted on-off toggle switch, or alternately through a remote momentary switch that can be fastened to the control stick. The smoke tank holds enough fluid for 3-4 minutes of continuous smoke.
N604CM Pilot Operating Handbook 8
Engine Cowling
The cowling is split into right and left sections. To remove the cowling, loosen the six ¼-turn SouthCo fasteners along the upper firewall and the two fasteners below the spinner and oil cooler air inlet. Next, remove the upper and lower piano hinge pins, thereby separating the right and left cowling sections. Lastly, the hinge pins connecting the cowl section to the fuselage may be removed, and the cowling detached from the fuselage.
Baggage Compartment
A baggage compartment is located aft of the occupants’ seats. Baggage weight is limited to 40 pounds. Lightweight bulky items may be placed in the cavity above the baggage compartment, but heavier items should be placed as low as possible to prevent shifting in flight. An elastic cargo net may be attached to the rear bulkhead and tie down hooks located on the underside of the spar carry-through box. Depending on pilot, passenger, and fuel loads, baggage may need to be further restricted to remain within gross weight and/or center-of-gravity (CG) limits.
Ventilation and Heating
NACA scoops on the forward fuselage sides provide fresh air ventilation. These scoops feed into rotating eyeball vents mounted in the corners of the instrument panel. The flow of air can be directed and controlled by adjusting the vent opening. No cabin heat is installed, but each passenger seat contains electric seat heater elements, controlled by switches on the panel.
N604CM Pilot Operating Handbook 9
Canopy
The Sonex canopy is hinged along the right side cockpit sidewall and opens by swinging over to the right. A stainless steel cable restrains the canopy at maximum opening to prevent damage. To close the canopy, rotate the canopy down to the left cockpit sidewall, aligning the canopy rail tabs into the slots in the left longeron. Push the canopy handle forward to latch the canopy into the closed position. Do not leave the canopy unattended while open as wind can blow it closed and crack the plexiglas or distort the canopy frame.

Crosswind Limitations
The aircraft has a demonstrated crosswind component of 15 mph when using full flaps. Landings during strong or gusty crosswinds may require less flap and slightly more airspeed on final approach to compensate for the wind condition s and provide better control authority.
Spin Recovery
Spins in the Sonex are conventional in both entry and recovery technique. Recovery is quick and without complication when the aircraft is loaded with the approved CG range. The preferred recovery technique is the “P.A.R.E.” technique. Reduce POWER, ALIERONS neutral, RUDDER opposite the rotation, when rotation stops ELEVATOR forward slightly to brake the stall, then recover normally from the resulting dive.
Maneuvers – Aerobatic Category
When operating in the aerobatic category (950 lbs gross weight), the following maneuvers with recommended entry speeds are approved:
Stalls (except whip stalls) --Spins --
N604CM Pilot Operating Handbook 17
Chandelles 80 – 110 mphLazy Eights, Wing Over 80 – 125 mphLoops, Horizontal Eights 110 – 150 mphAileron Rolls, Barrel Rolls 100 – 150 mphHammerhead (Stall Turn) 80 – 150 mphSplit S 75 – 110 mphImmelmann 110 – 150 mph
While executing these maneuvers, do not use abrupt control inputs. Aerobatics that may impose high loads must not be attempted. Bear in mind that the airplane is clean in aerodynamic design and will build speed quickly with the nose down. Proper speed control is essential for execution of any maneuver, and care must be exercised to avoid excess speed, which in turn can impose excessive loads.
Inverted Flight
Flight at negative “G” conditions is to be avoided due to lack of inverted fuel and oil systems.

Effect of Wheel Pants and Fairings
All performance figures listed were obtained with the wheel pants, gear leg and intersection fairings installed. Removing fairings will increase the aircraft’s total drag, and result in somewhat lower performance. With fairings removed, full power maximum airspeed is reduced approx 10 mph, and cruise flight at 2750 rpm results in approx 7 mph slower airspeed and 0.2 gph higher fuel consumption.

VII. Engine Operation
The Jabiru engine is equipped with an AeroInjector float-less carburetor. The AeroInjector is not altitude compensating, but is designed with an in-flight mixture adjustment control. The ability to lean the engine in flight allows the pilot to configure the engine for peak performance. Generally, Exhaust Gas Temperature (EGT) is used as an indication of mixture setting. All references to engine EGT are typically to the hottest cylinder(s). Due to the design of the induction system, the rear cylinder EGTs typically run 100º-150º hotter (thus leaner) than the front cylinders.
Starting
Starting the engine is accomplished by first turning on the battery (master) switch to the “BAT” position, closing the throttle to 1/8” “cracked” open, opening the fuel shutoff valve by moving the fuel shutoff control cable (black knob) to the forward “On” position, pushing the red mixture knob to the forward “Full-Rich” position, and then rotating the ignition key to the “Start” position. Fuel will begin to flow through the AeroInjector immediately after moving the mixture knob to full-rich position, and will drip into the air cleaner within a few seconds. If the engine starter is not engaged within 3-4 seconds, fuel will accumulate in the air cleaner and hinder normal starting. In extreme cases, excessive fuel accumulation may present a fire hazard.
Taxi
The design of the AeroInjector inherently results in a relatively rich mixture setting at low rpm. It is
N604CM Pilot Operating Handbook 38
recommended to “aggressively lean” at low rpm to reduce spark plug fouling and carbon buildup inside the engine. Aggressively leaning is defined as leaning to the point where any additional leaning or increased throttle movement will cause the engine to sputter or stumble from lack of fuel. Aggressive leaning creates a fail-safe situation where it is impossible to attempt a takeoff with a partially leaned mixture. Should a takeoff be attempted while aggressively leaned, the engine will sputter and instantly remind the pilot of the leaned mixture.
Take Off and Climb
Allow the engine to warm up to a minimum CHT of 200º Fahrenheit and oil temp of 100º before running at full power. Takeoffs should generally be conducted at full throttle, using the full rich setting. This allows the full required fuel flow to reach the engine, and is important to achieving full power as well as proper cooling. When the AeroInjector is properly adjusted, takeoff EGTs should be approximately 1200-1350º Fahrenheit. Under certain conditions, including high Density Altitude or very hot outside air conditions, it may be desirable or necessary to lean for takeoff. The recommended procedure is to lean the engine while on the ground so that full throttle EGTs are between 1100º -1200º, or until the engine runs smoothly. Engine roughness is very typical of overly-rich mixtures. Temperatures should be monitored throughout the takeoff roll and initial climb out, and the mixture adjusted as needed to remain within limits.
Cruise
N604CM Pilot Operating Handbook 39
Cruise flight is typically conducted between 2700 and 3000 rpm, but may vary with DA and temperature. Significant reductions in fuel flow can be achieved by properly leaning the engine during cruise flight. Additionally, proper leaning in cruise helps reduce carbon buildup inside the engine and prolong engine life.Prior to leaning for cruise, the engine should be allowed to stabilize in both rpm and temperature for a short time. Once stabilized, the engine should be leaned according to the following procedures, with minor modifications as needed to keep the engine running smoothly and within temperature limits. The engine may be operated in the following 3 modes: 1) Rich of Peak, whereby more fuel is consumed for the sake of cooler temperatures, near Peak, producing maximum power, but at greater heat and strain on the engine, or Lean of Peak, resulting in the lowest fuel flow. Peak EGT is approximately 1450º -1480º Fahrenheit. When operating Lean of Peak, EGTs will peak, then fall somewhat. The engine will not be damaged as long as CHTs are stable and within limits (350º Fahrenheit or less).
Rich of Peak (ROP): 1275º -1350º EGT
When leaning to ROP, the recommended procedure is to gradually move the mixture lever while watching EGT readings, stopping at the desired setting.
Peak Power: 1350º -1400º EGT
Gradually reduce the mixture setting until EGTs on the hottest cylinders reach approximately 1375º. Continue to monitor CHTs to ensure they remain within limits. This setting will generally produce the best power, but at somewhat greater engine stress.
N604CM Pilot Operating Handbook 40
Maximum Engine Stress: 1380º -1430º EGT
The engine is under maximum stress when EGTs are approximately 50º -100º rich of peak. This generally corresponds to EGTs of approximately 1380º -1480º. High power settings should be avoided in this mixture range. Lean of Peak (LOP): 1375º -1420º EGT
For LOP operation, it is preferable to lean quickly and drastically to reduce the time spent at peak EGT settings. This can be described as “the big mixture pull”, whereby the mixture knob is pulled out 1”-1.5” over the course of 3-5 seconds, while observing EGTs. Due to imbalances in the induction system, it may not always be possible to lean all 6 cylinders to LOP operation without causing engine roughness and/or vibration. If roughness occurs, richen the mixture slightly until the engine runs smooth again. Continue to monitor CHT to ensure they remain within limits. In some cases, several cylinders may be running near peak EGT while others are LOP. This poses no problem as long as the CHTs are stable and within limits, and the engine runs smoothly. If a suitable setting cannot be found, it may be necessary to richen the mixture enough to return to ROP operation on all cylinders to control CHTs.
Descent
Descent may be initiated by simply reducing the throttle to the desired rpm, while leaving the mixture setting leaned as in cruise. This will help prevent cooling the engine excessively during the descent and low power operation.
N604CM Pilot Operating Handbook 41
Prior to resuming application of cruise power setting, as in entering the traffic pattern, the mixture should be adjusted or richened accordingly. In the event of a touch-and-go landing, or go-around, the mixture should be returned to the takeoff setting (full-rich, or leaned as appropriate) before advancing the throttle to full.

IX. Systems
Electrical System
The aircraft is equipped with a simple but robust electrical system. Electrical power is supplied by a single 12 volt sealed lead-acid battery, and supplemented by a 20-amp output permanent magnet stator coil (alternator) on the Jabiru engine. The stator outputs alternating current (14-40 volts AC), which is then rectified to DC and regulated to a max of 14.0 volts (+/- 0.8 volts) by a separate regulator/rectifier unit. Output current varies with engine rpm, and at low rpm (2000 rpm or less) very little current is generated.
Instrument Panel Switches
The electrical system is controlled through two switches located on the instrument panel: the “BAT-ALT Switch” and the “AVIONICS Switch”. The BAT-ALT switch is a three-position switch: Off (down), Battery On (middle position) and Battery On + Alternator On (up). The AVIONICS switch is also a three-position switch: Avionics Off (down), Avionics On (middle position), and Alternate Power to Avionics On (up).
Normal practice is to start the engine with the BAT-ALT switch in the BAT position, and the AVIONICS switch in the OFF position. This ensures any short-term voltage spikes caused by engine starting are not transmitted to the avionics, and ensures the alternator is offline until the engine is started and running at a stable idle speed. Once the engine has started, the BAT-ALT switch can be moved to BAT+ALT (up position) and the AVIONICS switch can be moved to ON (middle position).
N604CM Pilot Operating Handbook 49
Power Bus: Main Bus & Avionics Bus
The electrical system includes two power distribution busses: the main bus and the avionics bus. The main bus is energized by the main Battery Contactor relay when the BAT-ALT switch is moved to either the BAT or BAT+ALT position, and supplies power to the fuel flow sensor, 12 v accessory plugs (cigarette lighter sockets), smoke system, and key switch starter position. Each circuit is fuse protected with an automotive blade-style fuse located on the engine-side of the firewall.
The avionics bus is energized off the main bus through the AVIONICS switch, and supplies fuse-protected power to the EFIS (including EMS and GPS receiver), COMM and Transponder. The avionics switch includes an alternate power supply pathway (labeled ALT PWR). This switch position energizes a separate connection directly to the battery and is independent of the main bus or battery contactor pathways. This is useful as a backup to a failed battery contactor or in situations where only essential avionics are desired to be powered (such as conserving electrical power after an alternator failure).
Overvoltage Protection & Alternator Control
The electrical system includes built-in protection from excessive voltage coming from the alternator (via the regulator/rectifier). A “crowbar overvoltage (OV) module” continuously monitors the output voltage of the regulator. Should the voltage rise above 16.4 volts for more than a few milliseconds, the OV module immediately shorts to ground, causing the 5 amp “ALT” circuit breaker to trip open. The
N604CM Pilot Operating Handbook 50
loss of this circuit breaker causes the alternator disconnect relay to disconnect the alternator from the regulator/rectifier and cease operation all together. An amber warning light will illuminate when the circuit breaker has tripped. Resetting the circuit breaker re-engages the ALT disconnect relay, bringing the alternator back online and connected to the electrical system. If the over-voltage fault is still present, the crowbar will trip again repeating the entire cycle. No more than one or two circuit breaker resets should be attempted in flight, as the problem likely requires detailed troubleshooting once on the ground.
12 Volt Accessory Plugs
12 volt accessory plugs (cigarette lighter sockets) are located in each corner of the panel and are approved for electrical loads up to 5 amps each. The sockets are only energized when the BAT-ALT switch is on (either the BAT or the BAT+ALT positions). Each socket is protected with a 7 amp fuse located in the main bus fuse block on the firewall.
Electrical Seat Warmers
Each seat contains an electric seat warmer in the seat cushion and seat back positions. Three-position rocker switches control each warmer and are located in each corner of the panel. The top position sets the warmer to high, drawing approximately 5 amps of current per seat. The bottom position sets the seat to low heat (3 amps), and the center position is off. The rocker switches are illuminated with colored LED’s indicating their status: green=high power, red=low power, off=warmer off. Seat warmers should only be used when the engine is running and providing sufficient electrical power so as to not drain the aircraft battery.

X. SERVICING REQUIREMENTS
Exterior Care
Fiberglass components are primed with Krylon Automotive Primer spray paint. Color coats are Rustoleum Color Top Coats, and select areas (cowling, wheel pants, gear leg fairings) are clear coated with Rustoleum Clear Coat. Vinyl graphics are applied in various areas.
Some exterior surfaces are bare aluminum polished to a high shine with the “Nuvite” polishing system. Polishing with Nuvite is a multi-step process, where the surface is initially polished with a rougher grit of polish to remove surface blemishes, mill marks and corrosion pitting. This step is typically performed with a napped-wool pad on a rotary buffer using Nuvite “F9” polishing compound; residue is removed with clean microfiber cloths and pure mineral spirits. The intermediate step is performed with a fine-grit compound to clarify the surface, remove swirl marks, and enhance the shine. This step is accomplished with Nuvite “C” compound on unbleached terrycloth (sweatshirt material) using a “Cyclo” polisher. The final step is performed with Nuvite “S” compound, hand-rubbed with a new microfiber cloth, or using a cyclo polisher with new terrycloth material.
Routine care of polished surfaces consists of removing dirt, fingerprints and insect remnants with pure water and a clean microfiber cloth, then hand-rubbing the affected area with “S” on a new microfiber cloth. Harsh cleaning chemicals are not required, and abrasive materials (e.g. shop rags, wash cloths, or scotchbrite pads) should not be used. In extreme cases, some additional re-polishing may
N604CM Pilot Operating Handbook 68
be required with F9 or C compounds. A complete re-polishing of the external surfaces is recommended annually to maintain a high shine; it is easier to maintain the shine with periodic touch-ups rather than repair a badly-degraded surface. Waxes and clear coats over the polished surfaces are not recommended as they tend to turn the polished surface cloudy after just a few days.
Windshield and Canopy Care
The windshield is made of a flat-wrap of lexan, and the canopy is blow-molded from “Soniplex”, Sonex’s proprietary plexiglass-like acrylic. Care must be taken to keep the plexiglass clean and unscratched. Flush away grit with water to prevent scratching, then wash with water with mild detergent or commercial plexiglass cleaner, such as Novus or Plexus. Never use benzene, gasoline, alcohol, acetone, carbon tetrachloride, lacquer thinner or glass cleaner with ammonia to clean plastic. These materials will damage the plastic and may cause severe crazing. The lexan windshield is especially susceptible to damage (crazing and cracking) from spilled gasoline, so care must be exercised while filling the main fuel tank.
Airframe Lubrication
Most moving parts on the airframe may be lubed with a medium viscosity general-purpose lubricant, such as “LPS-2”. The following items should be lubed annually, or as needed: control surface hinges; rod end bearings; oilite bushings in the elevator idler, aileron bellcranks, and control pushrods and control column pivots; tail wheel pivot and steering pushrod. Although not required, anti-corrosion sprays such as “ACF-50” or “Corrosion-X” may be applied to
N604CM Pilot Operating Handbook 69
the interior structures such as inside the wings, tail surfaces and fuselage tailcone as desired to inhibit internal corrosion.
Brakes
N604CM uses Great Plains hydraulic disc brakes. A single Hegar Model 3520 master cylinder drives both wheel brakes. Two brake pucks are used, with one located on the caliper and one fixed to the brake unit housing with 2 socket head screws. Pucks should be checked for wear annually, and replaced when the wear surface of the puck gets within 1/16” of the puck housing. Normal brake puck life is estimated at 500 hours. Fluid level should be checked for condition and the presence of air. If air is observed in the lines, or braking action is “soft” or “spongy”, air must be removed through bleeding the brakes and servicing with fresh fluid. Only Automatic Transmission Fluid (ATF) is used, and the use of aircraft/automotive brake fluids or silicon-based fluids will damage the seals within the system. Dexron VI ATF is preferred, but ATF Type A, Dexron II/III or Mercon V are also permitted.
Wheels, Tires and Tubes
McCreary Air Hawk (Aircraft Spruce PN 06-07710) 5.00x5 6-ply tires and Aero Classic Leak Guard (Aircraft Spruce PN 06-00755) 5.00x5 tubes are used. Other sizes and brands of tires may also be used. Tires should be replaced when the remaining tread depth reaches 1/16”. Inflate tires to a pressure of 40 PSI. Use of higher tire pressures is not recommended due to loss of shock absorption and increased wear of the tires. Clean and repack the main wheel
N604CM Pilot Operating Handbook 70
bearings after the first 100 hours, then subsequently every 200 hours or three years, whichever occurs first. Automotive wheel bearing grease is used, although other grease may be used so long as all traces of the old grease are first removed. Replace the bearings with Azusa ¾” ID tapered roller bearings (PN: AZ8256) when they become rough or “noisy” when turned by hand.
Propeller
The Sensenich propeller is a laminated wood propeller, coated with a composite shell. It is extremely durable, and resistant to corrosion and damage. Minor repairs can be made by the user to dress small nicks or chips in the outer composite coating. Larger repairs require consultation with the factory. Re-torque propeller bolts every 50 flight hours, every 6 months, or with drastic seasonal changes. Proper torque is 17 ft-lbs, +/-2 ft-lbs. Place the propeller in a horizontal position when not in use. Routine cleaning can be accomplished with mild detergents.
Battery
The Odyssey PC625 battery is a high performance, sealed lead-acid 12 volt battery, rated at 16 amp-hours and 625 cranking amps for 5 seconds. Under normal conditions, no servicing or maintenance is required. The battery cable terminals, lugs, and wires should be inspected annually for security and corrosion.
Fuel and Oil Requirements
N604CM Pilot Operating Handbook 71
The Jabiru engine is rated for 91 Octane automotive fuel, including up to 10% ethanol. Aviation grade 100LL fuel (Av-gas) may also be used, and may be combined with auto fuel in any proportion. Addition of TCP lead scavenger fuel additive is recommended when using 100LL fuel for extended periods of time, and will help prevent lead buildup inside the engine. Auto fuel, especially fuel containing alcohol, is susceptible to vapor lock in warm climates. Blending auto fuel with 25%-50% 100LL will greatly reduce the potential for vapor lock and/or detonation from insufficient octant rating, and is a recommended practice for ambient temperatures greater than 90º F.
The aircraft is equipped with a serviceable fuel filter attached to the fuel line just after it penetrates the firewall into the engine compartment. Inside the filter housing is a fine-mesh wire screen (40 micron) designed to filter out debris and contaminants. This screen should be inspected and cleaned every 100 hours, or annually. Replace the screen as needed. Care should be taken when reassembling the filter to prevent leaks or premature loosening of the filter housing.
Recommended oils include ashless dispersant 100-weight aviation oil and 15W-50 or 20W-50 multigrade aviation oil. The preferred oil is Phillips XC 20W-50 or AeroShell 15W-50 semi-synthetic for year-round use. Aeroshell W100 Plus is also acceptable for warmer climates above 45º Fahrenheit. Lighter weight oil may be used in colder climates if hard starting occurs. In very cold temperatures (below 32º F), W80 oil may be substituted. Engine pre-heat is recommended when temperature is below 40º F to save unnecessary wear and tear.
Oil change is recommended every 25 hours of engine operation, or every 4 months. A Napa Gold 1394 oil filter is
N604CM Pilot Operating Handbook 72
the preferred filter used on the Jabiru engine, and is changed along with the engine oil, hand-tightened only. When installing the filter ensure the filter canister is not damaged or dented as this can cause the filter to rupture under pressure and leak oil in flight. When checking the oil level on the engine dipstick (with the tailwheel on the ground), the level should be kept near the scribe mark on the custom dipstick (275-280 mm from bottom of oil filler threaded plug). Filling the oil level higher than this level (3.25 – 3.5 qts) will result in the excess oil expelled overboard through the breather vent and onto the belly of the aircraft. Overfilling the oil level will also result in higher cylinder head and oil temperatures. The aircraft is fitted with a custom oil recovery bottle that will minimize oil loss under normal conditions, and requires no routine maintenance.
Spark Plugs
Spark plugs (NGK D9EA) should be cleaned, tested, and re-gaped every 100 hours, or annually. If CHT probe ring terminals are used on the spark plugs, ensure the ring terminals are properly placed between the plug body and the sealing crush washer, not between the crush washer and the head. Apply anti-seize lubricant and re-torque plugs to 8 ft-lbs. Apply a small amount (pea sized drop) of silicon dielectric grease to the spark plug terminal and inside the plug boot to prevent corrosion. Using 100LL Av-gas may result in lead deposits forming on the plug electrodes. Replace plugs as needed, or every 200 hours.
Carburetor Air Filter
The engine is fitted with a K&N high performance filter (PN: RU-0630). Clean and re-oil the carburetor air filter every 50
N604CM Pilot Operating Handbook 73
hours, or annually. Very dusty conditions may require more frequent servicing of the air filter. To remove the air filter, remove the engine cowl and loosen the retaining worm-drive hose clamp on the filter housing.
Smoke System
The smoke system is compatible with multiple types of smoke oil, including “Super-Dri”, Corvus concrete form oil and light-weight petroleum oils such as 5W oil, automatic transmission fluid, or baby oil. Under no circumstances should diesel fuel or other highly flammable fluids by used. Ensure that the fill line cap has been securely tightened after filling the smoke fluid tank.
