GENERAL DESCRIPTION

Ref. Figures 6-1 & 6-2
Each main landing
consists of a landing gear assembly, shock
strut assembly and a wheel and brake
assembly. The landing gear assembly is
bolted to the fuselage frame at two
locations and to the shock strut assembly
at one location. The shock strut assembly
is in turn bolted to the fuselage frame.
Lubrication fittings are provided for the
pivot points and for the shock strut
assembly. Lubrication should be applied
sparingly and all parts wiped clean to

maintenance procedures on the landing
gear system.
The tail gear is comprised of the trunnion
attach points on the fuselage, the tail gear
spring, the tail gear spring supports, the
housing and spindle, the centering springs
and unlock control cable, the tailwheel
yoke and axel, the wheel, the tire & tube,
and various assembly and attaching
hardware..
The tailwheel spring is attached at the
forward end to a trunnion which allows
limited fore and aft movement of the
spring. The spring is supported just
forward of the bend by clamping brackets
which support it and limit fore and aft
motion. The housing and spindle is
attached to the lower end of the tailwheel
spring, and the yoke is attached to the
housing.
