DESIGN INFORMATION
ENGINE AND PROPELLER
The Cherokee "E" is powered by a Lycoming O-360-A4A
four cylinder, direct drive, horizontally opposed engine rated at
180 HP at 2700 RPM. It is furnished with a starter, 60 ampere
12 volt alternator, shielded ignition, vacuum pump drive, fuel
pump, and a dry, automotive type carburetor air filter.
The exhaust system is of the cross-over type to reduce back
pressure and improve performance. It is made entirely from stain-
less steel and is equipped with dual mufflers. A heater shroud
around the mufflers is provided to supply heat for the cabin and
windshield defrosting.
The Sensenich M76EMMS60 fixed-pitch propeller is made
from a one-piece alloy forging.
STRUCTURES
All structures are of aluminum alloy construction and are
designed to ultimate load factors well in excess of normal re-
quirements. All exterior surfaces are primed with etching primer
and painted with acrylic enamel.
The wings are attached to each side of the fuselage by in-
serting 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
