Section I
GENERAL
INTRODUCTION
The Pilot’s Flight Manual has been prepared with one fundamental
goal; to provide the pilot with information necessary to accomplish
the intended mission with maximum safety and economy possible.
SCOPE
The manual meets all FAA requirements for APPROVED DATA and
that data is so designated.
Schweizer has included additional supplemental data which is
intended to provide the pilot with information that expands, enhances
and eases his task.
ORGANIZATION
The contents of this manual is organized in the following manner:

SECTION I GENERAL
Information of general interest to the pilot, owner or operator of the
aircraft

SECTION II LIMITATIONS (FAA APPROVED)
Specifically defines the limiting factors, procedures and regime
within which the aircraft may be operated. FAA regulations
require that limitations not be exceeded.


SECTION III EMERGENCY AND MALFUNCTION
PROCEDURES (FAA APPROVED)
Each type of problem normally encountered in flight is defined and
the procedures necessary to cope with or alleviate the situation are
given. The data is recommended by the manufacturer and the FAA
as appropriate.

SECTION IV NORMAL PROCEDURES (FAA APPROVED)
Normal operation from engine start onward. As with emergency
procedures, the data given is that recommended by the
manufacturer and the FAA as appropriate.

SECTION V PERFORMANCE DATA (FAA APPROVED)
Aircraft performance is defined within certain conditions; some of
these are airspeed, weight, altitude, temperature, humidity and
wind velocity. The data is given in tabular or graph form and allows
the pilot to determine the aircraft’s capabilities related to the
intended mission and the conditions which are current.

SECTION VI WEIGHT AND BALANCE DATA
Aircraft weight and balance are major operational factors. Data is
provided by chart, graph and examples which allow the pilot to
accurately determine the aircraft’s gross weight and if the load is
distributed within the fore and aft, and lateral center of gravity.
The original weight and balance report, and equipment list
(required and optional equipment installed on the aircraft at the
time of licensing) are also contained in this section.

SECTION VII AIRCRAFT HANDLING, SERVICING AND
MAINTENANCE
Information contained in this section is extracted from the
Handbook of Maintenance Instructions and is highly selective. The
subjects chosen are those with which the pilot will have direct
involvement, either while at his normal base of operation or in the
field.


SECTION VIII ADDITIONAL OPERATIONS AND
PERFORMANCE DATA
Section V provides all basic data required and approved by the
FAA. The information in Section VIII is given by the manufacturer
to further inform the pilot of the aircraft’s capabilities and allow
him, by the use of graphs and tables, to utilize his aircraft to the
maximum degree.

SECTION IX OPTIONAL EQUIPMENT SUPPLEMENTS
A number of pieces of optional equipment are available for the
performance of specific tasks. In many cases the equipment is
readily removable and may be used in combination(s) with other
optional items. Whenever the installation of an option affects FAA
Approved Limitations, Procedures or Performance (Sections II
through V), an FAA approved supplement is required.
The supplements are filed in publication number sequence in the
section. In addition, there is tabular listing of all options and
modification kits in part number sequence. Notation is made as to
whether an FAA approved supplement is required. A second table
shows the compatibility of the various options with one another.
Each section is provided with an INDEX, listing the data by
paragraph number, title, and the page number.
A page number and date summary lists the numbers and date of the
most recent change. The summary for non-FAA approved data is in
the front matter (preceding this section); a similar summary is
provided for FAA approved data in Section II, for all information in
Sections II through V.
FAA Approved Option Supplements have their own indexes and
summaries.

DESIGN AND CONSTRUCTION
The Schweizer 330 Helicopter is a turbine powered rotary wing
aircraft constructed primarily of aluminum alloy. The main rotor is a
fully articulated three blade system while the tail rotor is a two
bladed semi-rigid type. Power from the turboshaft engine is
transmitted through eight drive belts and two drive shafts to the main
rotor and tail rotor transmissions. An overrunning (one-way) clutch
placed between the engine and main rotor transmission permits free
wheeling of the rotor system during autorotation.
The fuselage (with a central framework consisting of a mast support
structure, one bulkhead and a lateral roll beam) is a semi-monocoque
structure that is divided into three main sections. The forward section
comprises a pilot and passenger compartment and directly aft,
separated by a bulkhead is a faired housing enclosing the fuel cell,
mast, engine air inlet, accessories and drive system. Aft of this
structure is the aft fuselage combining both semi-monocoque and
monocoque construction. The pilot compartment may be equipped
with two or three passenger seats plus the pilot. A canopy of
transparent acrylic panels provides excellent visibility.
The standard 330 requires a minimum crew of one pilot-in-command
seated right side. Dual controls are available as an option. Left side
pilot-in-command is available as an option. The passengers sit
abreast of the pilot with the center seat slightly aft. A bench type
center seat is available to accommodate two passengers (for a total of
three). This option is available only with the left side
pilot-in-command configuration. Seat belts are provided for all
positions. The special trainer version is equipped with three seats and
three sets of controls, with a right seat pilot-in-command.
The instrument panel is located forward of the seats at the aircraft
centerline. The panel incorporates standard flight and engine
instruments in addition to warning and caution lights. The panel also
contains adequate space provisions for various arrangements of
communications and navigation equipment.
Stowage area is provided behind the outboard seats and in front of
the bulkhead.

Access to the engine compartment located beneath and to the rear of
the cockpit is provided by removable panels on each side of the
aircraft and also hinged access doors on each side contoured to the
fuselage shape.
The cockpit floor contains keel beams and also houses the
anti-torque (tail rotor pedal) controls. The engine and main rotor
transmission are supported by a tubular structure that is mounted on
the front and rear lateral cross beams. The cross beams are in turn
supported by the landing gear.
The power plant is the Rolls Royce Model 250-C20W gas turbine
engine with a maximum takeoff power rating of 235 SHP (five
minute limit). Only 220 SHP is used for maximum continuous
power.
Normal engine output speed is 91% N2= 5475 RPM.
Use of less than maximum available power provides a higher engine
critical altitude. The power turbine governor provides automatic
constant speed control of N2/rotor RPM.
The main rotor static mast is non-rotating and is rigidly attached to
the basic airframe structure. The rotor hub is supported by the rotor
mast.
Torque is transmitted independently to the rotor through the main
rotor drive shaft, thus lifting loads are prevented from being imposed
onto the main transmission with resultant thrust loading of
transmission parts.
The aft fuselage is a semi-monocoque and monocoque structure of
aluminum alloy frames and skin. The aft fuselage is the supporting
attachment structure for the stabilizers, tail rotor transmission and
tail rotor.
The overrunning clutch transmits power from the engine to the drive
shafts. The clutch needs no external controls and disengages
automatically during autorotation and engine shutdown. A short
drive shaft connects the engine to the lower drive pulley. Eight
flexible belts connect the lower pulley to the larger upper pulley
which houses the overrunning clutch.

The oil cooler blower is driven by the short engine drive shaft and
draws air in from the engine compartment. Air is then ducted and
forced through the engine/transmission oil cooler and exhausted
overboard.
The main transmission has an integral lubrication and oil
supply/cooling system.
Two doors are installed on the helicopter, one on each side for entry
and egress of personnel. Transparent windows with rotational air
vents are contained in the doors. Additional air vents are located on
each side of the instrument panel and overhead in front of the cockpit
bulkhead.
The tail rotor transmission is mounted on the aft end of the aft
fuselage and has a self-contained lubricant system. The tail rotor is
mounted on the output shaft of the transmission and consists of two
variable pitch blades.
The main rotor group consists of three main rotor blades, a fully
articulated main rotor hub assembly, and a swashplate and associated
mixer control mechanisms. The helicopter is equipped with either
(3) 269A1185-1 (23.75 in. trailing edge tab) or (3) 269A1185-5
(74.25 in. trailing edge tab) main rotor blades.
The pilot’s cyclic control stick and adjustable tail rotor control
pedals are directly in front of the pilot’s seat. The collective pitch
control stick is located on the left of the pilot’s seat. The entire
control system is a mechanically linked type. The copilot’s controls
are similar for the optional dual control installation.
The non-retractable landing gear is a horizontal, skid type gear,
attached to the front and rear cross beams. Aerodynamic fairing’s
cover the struts, from the fuselage to the skids. Nitrogen charged
landing gear dampers, between the struts and cross beams, act as
shock absorbers to cushion landings and provide ground stability.
Provisions for ground handling wheels are incorporated on the skid
tubes.
A 150 amp starter generator is supplied as standard equipment.
There are no limitations on use of generator output.
