CROSS REFERENCE LISTING OF POPULAR
NAME VS. MODEL NUMBERS AND SERIALS
All aircraft, regardless of manufacturer, are certificated under model number designations. However,
popular names are often used for marketing purposes. To provide a consistent method of referring to the
various aircraft, model numbers will be used in this publication unless names are required to differentiate
between versions of the same basic model. The following table provides a cross reference listing of popular
name vs. model numbers.

FOREWORD
This manual contains factory-recommended procedures and in-
structions for ground handling, servicing, and maintaining Cessna
Model 150-Series aircraft. This includes the Models 150, Reims
150, Reims/Cessna F150, 150 Aerobat, and Reims/Cessna F150
Aerobat. The Reims versions of the Model 150 is identical to the
Model 150 except that it is powered by a 0- 200-A Rolls Royce en-
gine. Besides serving as a reference for the experienced mechanic,
this book also covers step- by- step procedures for the less experi-
enced man. This manual should be kept in a handy place for ready
reference. If properly used, it will better enable the mechanic to
maintain Cessna 150-Series aircraft and thereby establish a repu-
tation for reliable service.
The information in this manual is based on data available at the
time of publication, and is supplemented and kept current by service
letters and service news letters published by Cessna Aircraft Com-
pany. These are sent to all Cessna Dealers so that they have the
latest authoritative recommendations for servicing Cessna aircraft.
Therefore, it is recommended that Cessna owners utilize the know-
ledge and experience of the factory-trained Dealer Service Organi-
zation.
In addition to the information in this Service Manual, a group
of vendor publications is available from the Cessna Service Parts
Center, which describe complete disassembly, overhaUl, and parts
breakdown of some of the various vendor equipment items. A list-
ing of the available publications is issued periodically in service
letters.
Information for Nav-O-Matic Autopilots, Electronic Communi-
cations, and Navigation Equipment are not included in this manual.
These manuals are available from the Cessna Service Parts Center.

1-3. DESCRIPTION. Cessna Model 150 and F150-
Series aircraft, described in this manual, are high-
wing monoplanes of all-metal, semimonocoque con-
struction. These aircraft are equipped with a fixed
tricycle landing gear. Through 1970 Models, they
are equipped with flat spring-steel main landing gear
struts and a steerable nose gear. Beginning with
1971 Models, these aircraft are equipped with tubu-
lar spring-steel main gear struts and a steerable
nose gear. The steerable nose gear is equipped with
an air/hydraulic fluid shl .• strut. Two-place seat-
ing is standard, and a double-width, fold-up auxiliary
rear seat may be installed as optional equipment.
Each Model 150 and Fl50-Series aircraft is equipped
with a four-cylinder, horizontally opposed, air-
cooled Continental or Rolls Royce engine, driving an
all-metal, fixed-pitch propeller. These aircraft fea-
ture a "wrap around" rear window and a swept-back
fin and rudder.

"beefed-up" in some areas in order to meet require-
ments of the Acrobatic Category, FAR Part 23. In
addition to the "beef-up", quick-release cabin doors,
two-strap shoulder harnesses, and aerobatic paint
design are standard. Only momentary inverted flight
is approved, therefore no inverted system is offered,
Removable seat and back cushions are provided to
allow occupants to use either a seat-pack or back-
pack type parachute during aerobatic maneuvers.
1-6. AIRCRAFT SPECIFICATIONS. Leading partic-
ulars of these aircraft, with dimensions based on
gross weight, are given in figure 1-1. If these di-
mensions are used for constructing a hangar or com-
puting clearances, remember that such factors as
nose gear strut inflation, tire pressures, tire sizes,
and load distribution may result in some dimensions
that are considerably different from those listed.
1-7. STATIONS. Station diagrams are shown in fig-
ures 1-2 and 1-3 to assist in locating equipment when
a written description is inadequate or impractical.
1-8. TORQUE VALUES. A chart of recommended
nut torque values is shown in figure 1-4. These tor-
que values are recommended for all installation pro-
cedures contained in this manual, except where other
values are stipulated. They are not to be used for
checking tightness of installed parts during service.
