SECTION 2
WEIGHT AND BALANCE.
Misloading carries serious safety consequences for any aircraft. If the C.G. is too far forward, it
may be difficult to rotate for takeoff or landing. If the C.G. is too far aft, the aircraft may rotate
prematurely on takeoff or tend to pitch up during climb. Longitudinal stability will be reduced.
This can lead to inadvertent stalls and even spins; and spin recovery becomes more difficult as
the center of gravity moves aft of the approved limit.
WARNING!
2.1 General
In order to achieve the performance, safety and optimal flying characteristics, which are designed,
into the aircraft, it must be flown with the weight and centre of gravity (C.G.) position within the
approved operating range (envelope). The pilot must ensure that the aircraft is loaded within the
loading envelope before takeoff. A weight and balance calculation can be helpful in determining
how much fuel or baggage can be boarded so as to keep within the allowable limits. Check
calculations prior to adding fuel to ensure against over loading.
2.2 Airplane weighing procedure
At the time of delivery, CLASS Inc. provides each airplane with the basic empty weight and centre
of gravity location. This data is supplied on Form WB-1

BushCADDY LSA Pilot Operating Handbook Rev.03 5 March, 2008
SECTION 6
EMERGENCY PROCEDURES
6.1 General
The recommended procedures for coping with various types of emergencies and critical situations
are provided by this section. Emergency procedures and those necessary for the safe operation of
the airplane as determined by the operating and design features of the airplane are presented.
These procedures are suggested as the best course of action for coping with the particular condition
described, but are not a substitute for sound judgement and common sense. Emergencies can occur
unexpectedly and the best corrective action may not always be the most obvious. Pilots should
familiarize themselves with the procedures given in this section, and be prepared to take appropriate
action should an emergency arise.
The procedures presented here are not intended to replace normal pilot training, but are provided as
a source of reference and review.
The presence of fire is noted through smoke, smell and heat in the cabin. It is essential that the
source of the fire be promptly identified through instrument readings, character of the smoke, or
other indications since the action to be taken differs in each case. Check for the source of the fire
first.
6.2 Engine Fire During Start
1. Shut down immediately
2. Shut off fuel
3. Full throttle to burn off fuel in lines to engine
4. Exit aircraft
5. If fire is minor, use fire extinguisher
6.3 Engine Fire in Flight
1. Shut off fuel
2. Throttle to idle
3. If radio communication is not required, turn master switch to OFF
4. If altitude permits, put aircraft into dive
5. Land immediately and exit aircraft
The possibility of an engine fire in flight is extremely remote. The procedure given is general and
pilot judgment should be the determining factor for action in such an emergency.
NOTE
Page 34 of 52
BushCADDY LSA Pilot Operating Handbook Rev.03 5 March, 2008
6.4 Electrical Fire in Flight
1. Turn master switch to OFF
2. Open cabin vents if installed.
3. Look for suitable landing field
4. Land as soon as possible
Loss of oil pressure may be either partial or complete. A partial loss of oil pressure usually indicates a
malfunction in the oil pressure system, and a landing should be make as soon as possible to investigate the
cause and prevent engine damage.
A complete loss of oil pressure indication may signify oil exhaustion, or may be the result of a faulty
gauge. In either case proceed towards the nearest airport, and be prepared for a forced landing. If the
problem is not a pressure gauge malfunction, the engine may stop suddenly. Maintain altitude until such
time as a dead stick landing can be accomplished. Don’t change power settlings unnecessarily as this may
hasten complete power loss.
Depending on the circumstances, it may be advisable to make an off airport landing while power is still
available, particularly if other indications of actual oil pressure loss such as sudden increase in
temperatures or oil smoke, are apparent and an airport is not close.
If engine stoppage occurs, proceed with POWER OFF LANDING.
NOTE
6.5 Loss of Oil Pressure
1. Maintain altitude for as long as possible
2. Don’t change power setting unnecessarily
3. Proceed towards nearest airport
4. If circumstances permit, shut down engine and execute a power off landing
NOTE
An abnormally high oil temperature indication may be caused by a low oil level, an obstruction, a
defective gauge, or other causes. Land as soon as practical and investigate the cause.
A steady, rapid rise in oil temperature is a sign of trouble. Land at the nearest airport and investigate the
problem. Watch the oil pressure gauge for an accompanying loss of pressure.
6.6 High Oil Temperature
1. Maintain altitude for as long as possible
2. Proceed towards nearest airport
3. If circumstances permit, shut down engine and execute a power off landing
Page 35 of 52
BushCADDY LSA Pilot Operating Handbook Rev.03 5 March, 2008
6.7 Engine Failure on Take-off
1. If there is sufficient runway land straight ahead
2. If below 200 ft. AGL pick a landing spot 10 degrees to the right or left of straight ahead. Do
not attempt a 180 degree turn
3. If above 200 ft. AGL, execute a gentle turn and pick the most suitable spot for a power off
landing
4. If enough altitude permits, switch fuel tanks and attempt to restart the engine
6.8 Engine failure in Flight
1. If enough altitude permits, switch fuel tanks and attempt to restart the engine
2. If engine restart fails, make emergency radio calls as required
3. Switch off electrics
4. Turn fuel selector to OFF
5. Pick a suitable landing spot and execute a power off landing
6.9 Power off Landing
1. Trim aircraft for best gliding airspeed (58 mph)
2. Pick a suitable field
3. Make emergency radio calls as required
4. Switch off electrics
5. Turn fuel selector to OFF
6. Land at lowest possible airspeed

SECTION 7
GROUND HANDLING AND SERVICING
7.1 Towing and Repositioning
The aircraft may be towed by its tail wheel.
To turn aircraft around manually, push gently on rear fuselage and push aircraft around on its tail
wheel.
7.2 Parking
1. Ensure that it is sufficiently protected from adverse weather conditions and that it presents
no danger to other aircraft or buildings.
2. Head into wind if possible.
3. Secure aileron and stabilizer controls with the seat belts or with gust locks. Gust locks are
preferred.
4. Chock the wheels.
5. Secure tie down ropes to the upper wing strut attach points and tail wheel at approximately
45-degree angles with the ground.
6. If using rope of non-synthetic material, leave sufficient slack to avoid damage to the aircraft
should the ropes contract because of moisture.
7. Use bowline knots, square knots or locked slipknots. Do not use plain slipknots.
8. Install pitot head cover.
9. Lock cabin doors when aircraft is left unattended.
7.2 Landing Gear
CAUTION: Low time pilots are advised to obtain conversion training from pilots experienced on
similarly equipped aircraft.
Main Landing Gears are equipped with Matco 6.00 x 6 wheels with 6.00 x 6 four-ply rating tires and
tubes.
Wheels are removed by taking off wheel fairings, hubcap, cotter pin, axle nut, retainer pin and the
two bolts holding the brake segment in place.
Tail wheel gear use MatcoWHLT-8
Remove by holding axle bolt with appropriate Allen key and remove nut. Withdraw the wheel from
axle. Service as per manufacturer’s instructions.
Nose wheel gear
1. Nose gear is not designed for impact of landing. Land on mains and lower the nose gear as
speed decays.
2. Avoid hard braking on soft or rough surfaces, or at forward C of G.
3. Do not attempt to “power out” of deep holes or ruts. Shut down, and manually push or pull
aircraft clear of obstacle.
4. Maintain tire pressure between 25 – 30 psi
5. When equipped with wheel pants, check clearance between tire and wheel pants.
Page 37 of 52
BushCADDY LSA Pilot Operating Handbook Rev.03 5 March, 2008
7.3 Propeller
Before each flight the propeller should be inspected for nicks. If found, they should be repaired as
soon as possible as per manufacturer’s instructions.
7.4 Oil
The oil capacity of the Rotax series of engines is 3 litres.
The recommended oil to be used in the Rotax series of engines is Brand name motorcycle oil with
gear lubrication additive. Use oil with API classification SF or SG. Change oil and oil filter every
25 hrs. as per manufacturer’s instructions.
Refer to Rotax Maintenance Manual included for more detailed information.
7.5 Fuel
7.5.1. Fuel grades
Use unleaded fuel as per Rotax operator’s manual. Avoid if possible use of Avgas 100 LL
7.5.2. Filling Fuel Tanks
Observe all required precautions for handling gasoline. Each fuel tank holds a maximum of 12 US
gallons. Fill the tanks to the bottom of the filler neck to obtain the standard plus reserve quantity.
Fuel should be distributed equally between each side.
7.5.3. Draining Fuel Strainer, sumps and lines
The fuel system sumps and strainer should be drained daily prior to the first flight and after refuelling to avoid the accumulation of contaminants such as water or sediment. Each fuel tank is
equipped with an individual quick drain located at the lower inboard rear corner of the tank. The
fuel strainer (galcolator) is equipped with a quick drain located on the lower front left corner of the
firewall. Each of the fuel tank sumps should be drained first. Then the fuel strainer should be
drained twice, once with the fuel selector valve on each tank. Each time fuel is drained sufficient
fuel should be allowed to flow to ensure removal of contaminants. This fuel should be collected in a
suitable container, examined for contaminants, and discarded.
When draining any amount of fuel care should be taken to ensure that no fire hazard exists
before starting the engine. Each quick drain should be checked after closing to make sure that it
has closed completely and is not leaking.
7.5.4. Draining fuel system
The bulk of the fuel may be drained by opening the individual drain on each tank. The remaining
fuel may be drained through the gascolator. Any individual tank may be drained by closing the
selector valve and then draining the desired tank.
Ensure that no fuel accidentally spills on Lexan windows or windshield. Fuel on Lexan will
cause the Lexan to discolor or crack.
CAUTION!
CAUTION!

BushCADDY LSA Pilot Operating Handbook Rev.03 5 March, 2008
7.6 Tire Inflation
1. For maximum service from the tires, keep them inflated to the proper pressure 24 psi for the
main tires and 45 psi for the tail wheel and 25-30 psi for nose wheel.
2. When checking tire pressure, examine the tires for wear, cuts, bruises and slippage. (Tire
changing position on the rim relative to the tube which is held in place by filler.)
7.7 Battery Service
1. The sealed 12-volt battery is located on mid firewall right side.
2. If the battery is not up to charge, recharge initially at 4 amps, reducing to 2 amps. Fast
charging is not recommended.
3. If charging from an external battery charger, disconnect ground lead from battery.
7.8 Brakes
1. Aircraft is equipped with Hydraulic Disk brakes
2. Brake Fluid, type as per manufacturer’s instructions or MIL-H-5606
3. The brake fluid level may be checked by unscrewing filler cap on master cylinders. Check
for leaks kinked brake lines, uneven wear on pads. Note the M66 brake lining has a visible wear
notch located at the end of the lining that would tell user when the pad is at minimum material
condition.
7.9 Shock Cords
1. Exhaust gases and oil can shorten the life of the shock cords.
2. They can be washed occasionally using mild detergent, rinse thoroughly with clear water.
Do not use solvents of any kind.
4. Foreign objects can damage the outer shell and leave rubber unprotected. If excessive breakage
is noted, change shock cords.
5. If shock cords no longer hold undercarriage tightly against stopper blocks, change.
7.10 Cleaning
7.10.1 Exterior Surfaces
To maintain the performance and durability of your aircraft, it is important to keep the interior and
exterior clean at all times. All traces of oil, gas and dirt should be removed. Accumulations over
time may cause fire and or corrosion. The aircraft should be washed with a mild soap and water.
Harsh abrasives or alkaline soaps or detergents could make scratches on painted or plastic surfaces,
or could cause corrosion of metal. Cover areas where cleaning solution could cause damage. To
wash the airplane, use the following procedure:
1. Flush away loose dirt with water
2. Apply cleaning solution with a soft cloth, a sponge or a soft bristle brush
3. To remove exhaust stains, allow the solution to remain on the surface longer
4. To remove stubborn oil and grease, or any accumulation of carbon wipe the area with a rag
dipped in lead free gasoline.
5. Rinse all surfaces thoroughly
6. Any good automotive wax may be used to preserve painted surfaces. Soft cleaning cloths or
a chamois should be used to prevent scratches when cleaning or polishing. A heavier
coating of wax on the leading surfaces will reduce the abrasion problems in these areas.
7.10.2 Windshield and Windows
1. Remove dirt, mud and other loose particles from exterior surfaces with clean water
Page 39 of 52
BushCADDY LSA Pilot Operating Handbook Rev.03 5 March, 2008
2. Wash with mild soap and warm water or with aircraft plastic cleaner. Use a soft cloth or
sponge in a straight back and forth motion. Do not rub harshly. To clean the Lexan
windows wash the windows with soap and water using a clean soft rag.
3. Once washed, polish the window with a good aircraft plastic cleaner.
Do not use gasoline, alcohol, benzene, carbon tetrachloride, thinner, acetone or window
cleaning sprays unless approved for Lexan.
CAUTION
7.10.3 Interior
Keep the interior of the aircraft clean and vacuum regularly. Never leave any equipment in an
area where it could become lodged and impossible to remove. This can cause an accident by
interfering with the flight controls.
A sunray shield may be placed over the windshield to prevent sunray damage to the interior.

SUPPLEMENTARY INFORMATION
8.1 Familiarization Flight Procedures:
Prior to flying solo in the BUSHCADDY LSA, it is strongly recommended that a thorough
familiarization flight be conducted with a pilot who is experienced on the BushCaddy or similar
aircraft. If you have never flown a taildragger, it is recommended that a taildragger endorsement be
acquired prior to flying solo. Particular attention should be paid to taxiing, and landing the aircraft
in cross wind conditions. The following is a suggested training program for familiarization on the
BUSHCADDY LSA.

SAFETY TIPS
7.11 Learn to trim for take off so that only a very light back pressure on the stick is required
to lift the aircraft off the ground.
7.12 The best speed for take off is about 40 – 50 mph under normal conditions. Trying to
pull the aircraft off the ground at too low airspeed decreases the controllability of the
aircraft in the event of an engine failure.
7.13 Before starting the engine, check that all radio switches, light switches are in the off
position so as not to create an overload situation when the starter is engaged.
7.14 Strobe lights should not be operating when flying through overcast or clouds, since
reflected light can produce special disorientation. Do not operate strobe lights when
taxiing in the vicinity of other aircraft.
7.15 In an effort to avoid accidents pilots should obtain and study safety related information
made available in FAA publications such as Regulations, Advisory Circulars Aviation
News, AIM and safety aids.
7.16 The shape of the wing fuel tanks is such that in certain manoeuvres the fuel may move
away from the tank outlets. If the outlets are uncovered, fuel flow will be interrupted
and temporary loss of power may result. Pilots can prevent inadvertent uncovering of
the outlets by avoiding manoeuvres which could result in uncovering the outlets.
Prolonged slips or skids which result in excess of 2000 ft of altitude loss, or other
radical or extreme manoeuvres which can cause uncovering of the fuel outlets must be
avoided as fuel flow interruption may occur when the tank being used is not full.
7.17 While taxiing aircraft in taildragger configuration, make small “S” turns to aid forward
visibility and avoid danger of collision with other aircraft. Always verify wing
clearance when taxiing on ramp in the vicinity of other aircraft and objects such as
buildings.
7.18 It is imperative that a full pilot proficiency check ride be undertaken with an
experienced pilot prior to flying the BushCaddy for the first time.
7.19 NEVER smoke around the vicinity of aircraft!
7.20 After refuelling stops, always check oil level before take off.
7.21 Thoroughly brief your passengers on emergency procedures, seatbelt operations and
proper door locking and unlocking techniques. Make sure that your passengers are
made aware that they will be flying in a aircraft that has not been certified to
Page 43 of 52

internationally recognized airworthiness standards, and is flying on a Special
Certificate of Airworthiness authority.

3.0 OPERATING INSTRUCTIONS
To ensure that the engine operates reliably, carefully observe all of the operating &
maintenance instructions.
3.1 Pre-Start Checks
Daily Checks (See Paragraph 5.1)
Move throttle position to FULL & check for ease of movement over the entire range.
3.2 Starting Procedure
Fuel Tap OPEN
Choke ON (in cold conditions)
Fuel Pump ON for 10 seconds then off
Throttle CLOSED to Stop
Master ON
Ignition BOTH ON
Starter PRESS
Page 46 of 52
BushCADDY LSA Pilot Operating Handbook Rev.03 5 March, 2008
Attention: Activate Starter for a max. 20 seconds, followed by a cooling period of 1
minute.
When engine runs, adjust throttle to achieve smooth running at approximately 1000 RPM.
Deactivate Choke. Check Oil Pressure has risen within 5 seconds - if not, shut down. It is
strongly advised to close choke while cranking on first attempt. To much choke will
cause over fuelling and loss of start. It is strongly recommended to crank the engine to
obtain oil pressure following an oil change before starting.
3.3 Warming Up Period, Ground Test
Start the warming up period with the engine running at 1000 RPM. Continue at 1400
RPM depending on ambient temperature, until oil temperature reaches 15oC (59oF).
Check the two ignition circuits at 1600 RPM. Note: - RPM with only one ignition should
not drop by more than 100 RPM.
DO NOT apply full power until CHT reaches 100 oC (212oF)
DO NOT allow cylinder heads to rise above 150oC during ground running.
3.4 Take-Off
Climb with the engine at maximum continuous power. Observe Oil & Cylinder Head
Temperatures & Oil Pressure Limits must not be exceeded !
3.5 Engine Stop
In normal conditions, cooling down the engine during descent & taxiing will permit the
engine to be stopped by switching OFF the ignitions.
3.6 Engine Stop and Start During Flight
Reduce power to 1000 RPM to cool engine for 30 seconds, then to idle. Switch ignitions
OFF. Starting procedure is the same as ground starting, without choke for a warm engine
& with choke for a cold engine. Note: Engine cools quickly with propeller stopped in
flight. Choke will therefore normally be needed to restart.

3. Avoid prolonged ground running at elevated RPM. Engine can be over heated, remember air
ducts are designed for in flight cooling. NOT E: remove AL L plastic bungs on engine.
E XHAU ST (4) CAR BY (2) OIL VENT (1) F U EL PUMP (1)
4. DO TAKE OFF AT FULL POWER.
F or the first few take offs climb at a higher airspeed. Reduce power at cross wind leg and shal low
climb (lower nose).
5. VARY your RPM when flying.
6. Avoid high nose altitude continual climbs . The higher the climb out speed the better for engine
cooling. No low s peed high nose altitude climb outs .
7. CI RCU IT WORK is possibly a good sequence for initial run in work . Abbreviate circuits
initially, step climb, climb shallow.
No glide approaches . Gradually reduce power. Avoid sudden heating up and sudden cooling down.
8. R E T ORQUE heads as suggested on warning sheet.
24 ft lb and .010” valve clearance al l done cold. Subsequent torquing of around 22 to 24 seems to
help in settling down head bolts and heads.
9. Don’t BABY YOUR ENGINE but monitor carefully CHT and oil temp initially especially during
the first few hours of operation.
Remember engines need to be flown. T hey are designed for this purpose. Do not use full power
before CHT reaches 100oC.
Ring bed in is accomplished better at 75% power and above. Avoid heat build up. Monitor CHT and
oil temps . Vary R PM. Initial temps will be elevated due to friction of a new engine.
Failure to operate at realisic power settings could be detrimental .
10. Do not use any type of automotive oil. These oils have not been blended for the purpose of air
cooled aero engine operation and will be detrimental to its operation.
11. U se AVGAS 100 LL or the highest Octane Mogas above 95 containing lead. Engines not
shimmed on the cylinder base should only be run on AVGAS .
12. When you change oil from the “run in” type to the “normal” oil at or around 25 hrs replace oil fil
er. You may want to cut the filter open for inspection. It is usual in Jabiru engines to find
a small amount of aluminium but definitely no metal. If bearing metal is present contact the
Jabiru Service Department.
13. With ignition and master OFF and throttle closed turn the prop by hand and observe engine for
odd nois s or heavy movements .
Check for regular compressions, if irregular, firstly check tappet adjustment. Operation with
incorrectly adjusted tappets will result in damage to valves, valve seats , guides and overhead gear .
