DESCRIPTION AND OPERATION
OF THE AIRPLANE AND ITS SYSTEMS
7.1 THE AIRPLANE
The PA-28-181 Archer II is a single-engine, low-wing monoplane of all
metal construction. It has four-place seating, two hundred pound baggage
capacity, and a 180 horsepower engine.
7.3 AIRFRAME
The basic airframe, except for a tubular steel engine mount, steel
landing gear struts, and other miscellaneous steel parts, is of aluminum alloy
con-struction. The extremities - the wing tips, the cowling, the tail surfaces -
are of fiberglass or ABS thermoplastic. Aerobatics are prohibited in this air-
plane since the structure is not designed for aerobatic loads.
The semi-tapered wings havea laminar flow type NACA 652-415 airfoil.
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.
71.5 ENGINE AND PROPELLER
The Archer II is powered by a four cylinder, direct drive, horizontally
opposed engine rated at 180 horsepower at 2700 rpm. It is furnished with a
starter, a 60 ampere, 14 volt alternator, a shielded ignition, vacuum pump
drive, a fuel pump, and a dry, automotive type carburetor air filter.
The exhaust system is made entirely from stainless steel and is equipped
with dual mufflers. A heater shroud around the mufflers is provided to
supply heat for the cabin and windshield defrosting.
