CHEROKEE CRUISER
DESCRIPTION
AIRPLANE AND SYSTEMS
THE AIRPLANE
The Cherokee 140 is a single-engine, low wing monoplane of all metal construction. It is
available in two versions, the Cherokee Cruiser and the Cherokee Flite Liner.
The Cherokee Cruiser, which is the standard model, has a two-place configuration with a
third and fourth family seat offered as optional equipment. Economy, comfort and a wide range
of options make the Cherokee Cruiser a versatile business or personal airplane.
The Cherokee Flite Liner is basically a standard model Cruiser with optional equipment
installed that is tailored for flight instruction. This equipment includes instruments, radio and
lights. The Cherokee Flight Liner also has its own distinctive exterior color scheme. The
simplicity, stability and dual flight controls make it an especially good instructional airplane.
AIRFRAME
The basic airframe is of aluminum alloy construction. The extremities - wing tips, cowling,
tail surfaces - are of durable fiberglass.
The wings are attached to each side of the fuselage by insertion of the butt ends of the
respective main spars into a spar box carry-through which is an integral part of the fuselage
structure, providing, in effect, a continuous main spar with splices at each side of the fuselage.
There are also fore and aft attachments at the rear spar and at an auxiliary front spar.
The wing airfoil section is a laminar flow type, NACA65
2
-415 with the maximum
thickness about 40% aft of the leading edge. This permits the main spar carry-through structure
to be located under the rear seat, providing unobstructed cabin floor space ahead of the
rear seat.
ENGINE AND PROPELLER
The Lycoming 0-320-E3D engine installed in the Cherokee PA-28-140 is rated at 150
horsepower at 2700 rpm. This engine has a compression ratio of 7 to I and requires 80/87
minimum octane fuel. The engine is equipped with direct drive or optional geared drive starter,
a 60 ampere alternator, dual magnetos, vacuum pump drive, diaphragm type fuel pump and a
float carburetor.
Exhaust gases are carried through a system constructed of heavy gauge stainless steel which
incorporates heater shrouds to provide cabin heat, defrosting, and carburetor deicing.
