Landing Gear - Piper AZTEC D PA-23-250 Owner's Handbook Manual

THE PIPER AZTEC "D" SECTION II
All windows are double pane except the second window on
the left side which is the emergency exit window. A storm window
located in the forward lower section of the pilot's side window
opens downward and in when unlatched.
The wing structure is lightweight but rugged, and consists of
a massive stepped down main spar, a front and rear spar, lateral
stringers, longitudinal ribs, stressed skin sheets, and a readily
detachable wing tip section. The rectangular plan form of the
wing simplifies the construction while providing excellent sta-
bility and performance characteristics.
The wings are attached to the fuselage steel tubular struc-
ture with fittings at the sides and in the center of this structure,
and the main spars are bolted to each other with high strength
butt fittings in the center of the fuselage, giving the affect of a
continuous main spar. This arrangement combines high strength
and lightweight structure.
LANDING GEAR
All three landing gear units on the Aztec incorporate the
same soft acting air-oil struts, and contain many directly inter-
changeable parts. (See Section V, for gear maintenance.)
Main wheels are 600 x 6 Cleveland Aircraft Products units
with disc type brakes with metallic lining and 700 x 6 tires with
an eight ply rating. The nose wheel is a Cleveland 600 x 6 model
fitted with a 600 x 6 tire with a four ply rating. All tires have
tubes. (See Section V, for tire service.)
Main gear brakes are actuated by toe brake pedals on the
left set of rudder pedals. Hydraulic brake cylinders located in
front of the left rudder pedals are readily accessible in the cock-
pit for servicing. Toe brakes for the right side are available as
optional equipment. A brake fluid reservoir, which is connected
to the brake cylinders with flexible lines provides a reserve of
fluid for the brake system, and is mounted on the fuselage
structure inside. the left nose access panel. (See Section V, for
brake service.)
