1.5 WEIGHT AND BALANCE INFORMATION

A – WEIGHING PROCEDURE

Following procedures are suggested for weighing operations

01 Before weighing, remove dirt, grease, humidity etc. from the aircraft.
02 The aircraft weighing shall be performed in a closed shed to avoid incorrect readings of

the scale due to wind.
03 To determine the center of gravity, the aircraft shall be set on attitude of horizontal flight.
04 All the equipment items included in the certified tare weight shall be installed IN THEIR

POSITION when performing the weighing.- These equipment items are part of the

weighing report.­05 The scales must be properly calibrated, zeroed and used as per builder’s instructions. The

scales and the suitable supports for the aircraft, when needed, are normally positioned

under the aircraft wheels. Other structural points that can suitably support the aircraft may

be used, as for example the jack plates on the main spar. These points must be clearly

pointed out in the weighing report.
06 If not otherwise required by the aircraft specifications, the fuel system must be drained

until the indicator shows “ZERO” or “EMPTY” when the aircraft is on attitude of horizontal

flight. The fuel quantity remaining in the tank, in the pipes and in the engine is called

“RESIDUAL FUEL” and must be included in the tare weight.- In particular cases the

weighing can be performed with full load of fuel, provided that an accurate instrument is

available to determine the exact weight.­07 If not otherwise specified in the aircraft specifications, the oil system shall be completely

drained with all the drain cocks open. In these conditions, the oil quantity remaining in the

tank, in the pipes and in the engine is called “RESIDUAL OIL” and must be included in the

tare weight. When weighing is performed with a full load of oil, the actual tare weight is

equal to the real registered weight minus the weight of the oil contained in the tank (oil

weight = oil capacity in gallons multiplied by 7,5 lbs). It must be specified in all weighing

reports whether full load of oil is included in the weights or if weights are considered after

oil drainage.
08 The brakes must not be operated when reading the scale.

09 After removing the aircraft from the scale, take note of the tare weight.

B - WEIGHING AND BALANCING CALCULATIONS

01 UNITARY WEIGHTS FOR WEIGHING AND BALANCING PURPOSES

Fuel : 6 lbs per Gal/USA = a 0,720 gr per liter

Turbine fuel : 6,7 lbs per Gal/USA = a 0,803 gr per liter

Lubricating oil : 7,5 lbs per Gal/USA = a 0,900 gr per liter

Crew and passengers : 180 lbs per person = a 81 kgs per person
02 Take the reference plane of the longitudinal distances from the C.N.. If not shown,

choose a suitable one provided that once it has been determined, it will be the only

reference for the calculation of arms and moments.

03 ALGEBRAIC SIGNS

Great care must be taken over assigning the right algebraic signs ( + o - ) during the

whole balancing calculation. For uniformity purposes, when doing these calculations, you

should always consider to observe the aircraft with its nose on the left side. In this

position, any left side arm (forward) of the reference has a minus (-) sign, and any right

side arm (rear) of the reference has a plus (+) sign. Any weight added to the aircraft on

any side of the reference HAS A PLUS (+) SIGN; any removed weight HAS A MINUS (-)

SIGN.-

When weights are multiplied by arms, the result will have a (+) sign if signs are the same,

and a (-) sign if signs are different.

Following combinations are possible:

Weights added in front of the reference plane: (+) weight x (-) arm = (-) moment

Weights added at the back of the reference plane: (+) weight x (+) arm = (+) moment

Weights removed in front of the reference plane: (-) weight x (-) arm = (+) moment

Weights removed at the back of the reference plane: (-) weight x (+) arm = (-) moment

The total weight of the aircraft is equal to the tare weight of the aircraft plus the added

weights minus the removed weights.

The total moment of the aircraft is determined by the algebraic sum of the aircraft

moment with tare weight and all the single moments of the added and/or removed items.

1.6 TIRE INFLATION PRESSURES

Nose gear tire inflation pressure: 26 psi
Main landing gear inflation pressure: 26 psi

Check tires at each refuelling to make sure there are no cuts, foreign matters, irregular wear; an
irregular wear could be due to a bad use of brakes as well as to a wrong wheel alignment.

Replace worn tires.

An excessively worn tire considerably increases the possibility and the danger of burst.

NOTE : tires shall be disposed of in compliance with current environmental provisions.

1.7 APPROVED OILS AND CAPACITY

- Type : for car use, classification API "SF" or "SG"

- Quantity : 0,7 gal max. level – 0,5 gal. minimum level, with filter total capacity 0,8 gal

1.9 GENERAL SAFETY INFORMATION

INTRODUCTION

Some maintenance and aircraft repairing methods may involve the risk of physical injuries or
other risks for your health. This section lists some of these dangerous operations in
alphabetical order, together with the materials and the relevant equipments. The necessary
precautionary rules to avoid these risks are pointed out.
This list is obviously incomplete and all the repairs, including handling of the materials,
should be carried out keeping health and sanitary rules in mind.
Please read the safety regulations for use of the materials provided by the manufacturer or by
the supplier before using any product.

ACIDS AND ALKALIS
Caustic soda and sulphuric acid, for example, used for batteries and in cleaning products, are
irritating and corrosive for skin, eyes, nose and throat. They may cause burns. They can
destroy normal overalls. Avoid to spray such products on your skin, eyes or clothes. Wear
suitable protective gloves and glasses. Do not inhale fumes. Make sure that all necessary
products to wash your eyes, for the shower and soap are always within reach, should
accidental sprays occur.

BATTERY ACID
The gases released during battery charge are explosive. Never use flames or allow sparks to
occur near batteries in charge or just charged. Make sure that there is a suitable ventilation.

RESINS AND HARDENERS

Contact of your skin with resins and not polymerized hardeners may cause irritations,
dermatitis and intradermal absorption of toxic and harmful chemical products. Sprays may
injure your eyes. Provide for a suitable ventilation and avoid contact with your skin and eyes.
Anaerobic adhesives, cyanoacrylates, and other acrylics (superglues): many of these are
irritating, sensitizing of harmful for your skin and/or your respiratory system. Some are
irritating for your eyes, avoid contact with your skin and follow the instructions provided by the
manufacturer. The cyanoacrylate based adhesives (superglues) must never get in touch with
your skin or eyes. Should your skin or ophthalmic tissue remain tied, cover it with a clean
damp tampon and call the doctor immediately. Do not try to separate the tissue. These
product must be used in well ventilated areas because its fumes may irritate your nose and
eyes.

ISOCYNATE (POLYURETHAN) BASED ADHESIVES/DOPES

If you suffer from asthma or respiratory allergies you should not work with this kind of materials
nor work close to them, since they could cause sensitization reactions. An excessive exposure
can irritate your eyes and respiratory system. Excessive concentrations may affect your
nervous system and could even be soporific. Loss of consciousness may occur in extreme
cases. A continuous exposure to concentrations of vapors could have negative effects on your
health. An extended contact with your skin can have a degreasing effect which can irritate your
eyes and might cause dermatitis. Sprays into your eyes will cause irritations and possible
damages. Spraying should rather be executed in ventilated cabins provided with aspirator in
order to remove vapors and drops from the area. Wear gloves, glasses and faceplates.

MAINTENANCE MANUAL

STORM Century S-LSA

STORM Century S-LSA STORMAIRCRAFT

ASBESTOS

If inhaled, asbestos may cause damages to your lungs and in some cases cancer.
Asbestos is used for brake linings. Asbestos dust to be wasted should first be dampened, then
put into a sealed container with a special label to be sure that it will be wasted in a safe way.
Should you need to cut or to drill materials containing asbestos, wet the part and use only slow
speed hand or electrical tools. The present law does not allow to use asbestos.

ANTIFREEZE

See also: isopropyl alcohol, glycol, methanol, solvents.

Highly flammable, flammable, combustible.
It is used in the cooling system of the cylinder heads. If heated, the antifreeze (glycol) can
release detrimental vapors. Avoid to inhale them. Antifreeze can be absorbed in injurious and
toxic quantities through your skin. If ingested, it could be lethal and a doctor should be contacted
immediately.

COMPRESSED AIR EQUIPMENTS

Never point a high pressure nozzle at your skin, since the liquid could pierce your skin and
cause hard injuries.

GENERAL SHOP TOOLS AND EQUIPMENTS

It is fundamental that tools and equipments be kept in good conditions and that, if necessary,

the proper safety equipments be used.

Never use tools or equipments for purposes other than their specific use.

Never overload equipments like hoists, jacks, trestles or slings.

The damage caused by overload is often not immediately perceivable and it might cause fatal

damages next time you use it.

Do not use damaged or defective tools, specially high speed equipments as grinding wheel. A

grinding wheel can break without notice causing hard injuries. Wear suitable protective glasses

when using grinding tools.

GAS CYLINDERS

Take care while using gases, like oxygen, acetylene, etc. to avoid leaks from the cylinders or
from the piping and avoid lighting sources.

FUEL

Try as far as possible not to get your skin in touch with fuel. Should it occur, wash the affected
part with water and soap.

GASOLINE

Highly flammable. Observe the signs “no smoking” .- The ingestion might cause irritations of
your mouth and throat and the absorption in your stomach could cause you a torpor condition
and loss of consciousness. Transit of liquids through your lungs, for example when vomiting,
is a serious risk. Gasoline dehydrates the skin and may cause irritations and dermatitis if the
contact is prolonged and repeated. Gasoline can irritate your eyes. It can contain remarkable

q

uantities of benzol, which is toxic if inhaled, and the concentration of gasoline vapors must

MAINTENANCE MANUAL

STORM Century S-LSA

STORM Century S-LSA STORMAIRCRAFT

be kept very low. High concentrations will irritate your eyes, nose and throat and cause
nausea, headache, depression and symptoms of drunkenness. Very high concentrations will
cause a quick loss of consciousness.
While using gasoline, make sure that there is always a suitable ventilation.
Should there be a high vapor concentration raised from pouring it in a limited space, avoid as
far as possible the serious consequences of inhalation. Gasoline shall not be used as a
cleaning solution. Avoid to do transfer operations with your mouth.

OVERHUNG LOADS

Danger must always be taken into consideration when a load is lifted and hung. Never work
under loads which are hung or lifted without any support. Make sure that the lifting units like
jacks, hoists, slings, etc. are suitable for the specific work and conditions and that they are
regularly overhauled.

INSULATING FIBERS

These are used for soundproofing. The fibrous nature of the surfaces and the sharp edges
may cause skin irritations. The effect is normally physical and not chemical. The necessary
precautions shall be taken to avoid the prolonged contact with your skin, taking up suitable
working methods and wearing protective gloves.

BRAKE FLUID

Highly corrosive, avoid contact with painted parts. If the brake liquid is erroneously poured on
painted parts, immediately wash with cold water.
Sprays on skin and eyes are irritating. Avoid as much as possible contact with your eyes and
skin.

SYSTEM AND AVIONICS MAINTENANCE

The attached table is a reference guide for the development of a maintenance schedule for all
systems and avionics installed on the aircraft.­The terms used in the table will have the following meaning:

OPERATIONAL TEST: quantitative check to make sure that a system, a system function or
equipment is working as expected.- It is mainly used to search failures or malfunctions.- No
equipments nor instruments other than the ones supplied with the aircraft are needed for this kind
of check.-

FUNCTIONAL TEST: quantitative check to make sure that a system, a system function or
equipment is working within the limits and the tolerances as defined in the applicable test
specifications.- This kind of check normally requires functional testing equipments (usually test
benches) and the recording of the taken measurements.-

BENCH TEST: this test points out the operational mode of check rather than its content.- It is
used for the quantitative check (functional check) of the operation parameters of the instruments
taken off the aircraft.
The laboratory instruments, the builder’s procedures and data or approved international standards
shall be applied for the bench test of the aircraft on trial.

VHF unit Functional Test 24 months

CHAPTER 3

STRUCTURES

3.1 DESCRIPTION OF FLIGHT CONTROLS

The main, traditional flight controls used by the pilot for the immediate control of rolling, yaw and
pitching consist of:

Aileron - control
Rudder - control
Stabilator - control
Attitude control, Stabilator Trim

The flight controls are provided with stops to limit the travel of every aerodynamic surface
controlled by the system.
The flight controls can be operated from the pilot seats, both equipped with control stick for
aileron/Stabilators operation and with rudder pedals to operate the rudder.

1- Aileron control

The aileron control drive, which is connected to the control stick, is a rigid rod with connecting
rods mounted on double ball bearings.

2- Rudder, fin control surface

The fin control surface is controlled through the pedals, and the control is transmitted from
pedals to fin control surface through cables.

3- Stabilator control

The Stabilator control is a rigid rod working on bearings and is operated through the control
stick in the cockpit.

4- Stabilator Trim

Two pull-up/push-down buttons on both control sticks operate an electric actuator positioned
on the rear part of fuselage, which transmits the movement to the Stabilator trim through a
transmission bar. The transmission from le actuator works through a bar connected to the
hinge bracket of the Stabilator trim (see aircraft structure chapter).
The position of the trim device as to the setting range is displayed by an indicator on the lower
part of the instrument panel.

5 FUEL SYSTEM

The fuel system is connected to 2 wing tanks. In normal operating conditions, an AC pump located
on the left of the engine in an advance position supplies fuel to the carburetors. From the wings the
fuel go to a little tank installed in the upper side of the firewall inside the cabin from here to the
shut-off valve in the FW center consol with two positions: open/closed ; then to the gascolator filter
located in the lower left part of fuselage on the firewall. The gascolator also has a bleeding. The
fuel flows then from the gascolator to the electric pump controlled by the pilot, located on top of it,
then to the mechanical pump driven by the engine and then to the switch. From the switch, located
on the upper part of the circuit, the fuel reaches the carburetors. Some of this fuel starts the fuel
pressure gauge up, and the exceeding part flows back through the top of the wing tanks . Should
one of these pumps fail, feed is guaranteed by the other one. We suggest you to operate the
electric pump during take-off and landing.

In the switch fuel return line, there is installed a Jet with 1mm hole : clean each 300 hours.

NOTE : we suggest you to keep tank always full so as to avoid humidity condensation

inside. Always fill with previously filtered and clean fuel.

Empty tank completely using the bleeding screw under the tank on the decantation tank; open also

the bleeding screw under the gascolator.
CAUTION: keep fire extinguisher within reach when draining the tank, take all necessary

precautionary measures, keep the area ventilated.
Disconnect fuel feed/return flow pipes
CAUTION: if you do not expect to change the fuel pipes, we suggest to close them with a pin of the

same size as the inside diameter of the pipe.

INSTALLATION

a) carefully clean the inside of the tank from any processing residual, make sure that the breather
is free.
b) invert the sequence for installation

5.2 FUEL SYSTEM FITTINGS

GASCOLATOR FUEL FILTER

(DETAIL G - FUEL LINE DIAGRAM)

The gascolator, containing 0,13 gal fuel, is in the lowest part of the fuel circuit, on the firewall. The
fuel filter is inside the gascolator.
The gascolator has a pressure bleeding where the condensation residuals are collected; it can be
reached from the lower outside part of the nacelle.

ELECTRIC FUEL PUMP

(DETAIL H - FUEL LINE DIAGRAM)

This pump is used as auxiliary or emergency pump which can be turned on during take-off or
landing or in particular emergency conditions. The operation of this pump works on the vibrating
movement of a diaphragm cylinder which creates suction and pressure; its movement is controlled
by an electromagnet.

MECHANICAL FUEL PUMP

The mechanical diaphragm pump is controlled directly by the engine. When the engine is on, the
mechanical pump sucks fuel through the electric fuel pump, and sends it to the carburetors with a
pressure of about 0,15 - 0,4 bar (2.2 - 5.8 p.s.i.).

MAINTENANCE MANUAL

STORM Century S-LSA

STORM Century S-LSA STORMAIRCRAFT

CARBURETOR
Description : two vacuum carburetors "Bing 64/32": the incoming air sucks the membrane which

causes valve and needle to rise.
There is no drive of the mixture control (MIXER); the carburetor valve is controlled by the vacuum
created on a membrane by the air taken in by the carburetor and not by a manual gear (wire or stiff
rod). When the carburetor is set in a correct way, the stoichiometric proportion air/carburetor is
steady.
The synchronization of the carburetors must be performed by Rotax technical staff, using the
vacuometer sockets under the suction ducts. The carburetor setting is fixed and predetermined
with only one variant: the needle position may be changed.
The carburetor has a circuit for cold start to enrich the air/fuel mixture controlled through the
STARTING CARB. lever, working on an idling circuit duct.

CAUTION : some total or partial breakaways of the carburetors were supposed to be due
to wrong installation, to vibrations caused by unbalanced propellers and to a bad
synchronization of carburetors with subsequent engine bumping.
Frequent checks must be carried out. Leave a 7mm opening on the clamp for normal
tightening; the clamp must be original and with its screw facing down.

The carburetor has also an overflow in the fuel bleeding system.

CAUTION : do not throttle overflow pipes in any way, make sure that they do not dump fuel
directly on or near the exhaust manifolds.

5.5 FUEL AND AIR CIRCUIT IN THE CARBURETOR

The fuel circuit is made of a needle valve operated by the rocker controlled by floats located in

the chamber. The fuel level in the chamber must be steady: floats which open and close the needle
valve keep a steady fuel inflow to the engine.
The fuel level in the chamber can be modified if necessary.

CAUTION : modifying the fuel level will affect the titer of the air/fuel mixture
Lowering the fuel level in the chamber as to normal, the carburetion will be leant.

Increasing the fuel level in the chamber as to normal, the carburetion will be richer.
The fuel level must be measured from the upper chamber lip and it must be about 12 - 13 mm.
The air circuit is basically made of a suction filter and of the conduct conveying air to the engine.

The purpose of this filter is to avoid that impurities get into the engine. The paper filter may be
cleaned with a special detergent: "Filter Clean" ; it must be used strewing the filter both inside and
outside, leaving it on for 10 minutes. The filter must then be plunged into a basinful of water and
finally carefully rinsed with water avoiding to scrub it. The filter must be dried in quiet air.

Do not use compressed air to dry the filter.

MAINTENANCE MANUAL

STORM Century S-LSA

STORM Century S-LSA STORMAIRCRAFT

WARM AIR

Storm Century does not require the use of warm air to carburetor, since it utilizes a simple “warm
air " system.

The "warm air" system avoids the need for a heat exchanger, taking air directly from the engine
compartment. In this way, warmer and thinner air enters the cylinders, thus involving a slight drop
of the engine power performance.
This system is considered simple because there is a "warm/cold" valve in "warm air" connected
with the throttle and whenever required, the maximum power can be reached inserting cold air to
carburator. "STORM Century S-LSA" has no "warm/cold" valve.

CAUTION : a traditional heat exchanger may be installed for warm air to carburetor. If
installed, the maximum jets in the carburetor shall be modified from 158 to 155.

CAUTION : icing may occur in the carburetor in particular circumstances, therefore avoid all
flight conditions where icings are possible.
