Revision G

LANDING GEAR
The landing gear incorporated within the
amphibious floats is a retractable, quadricycle
type with two swiveling nose (or bow) wheels
and four (4) (two (2) dual sets) of main wheels.
Shock absorption is provided by air-oil shock
struts on the two main landing gear assemblies
and composite flat springs on the nose gear
assemblies. Each main wheel is equipped with
a hydraulically-actuated disc brake.
Landing gear extension and retraction is
accomplished by two (2) electrically-driven
hydraulic pumps and four (4) hydraulic
actuators (one (1) for each gear).
The hydraulic pumps are located in the aircraft
empennage and can be accessed by removing
the aft cabin bulkhead. The hydraulic actuators
are located adjacent to each gear.
Hydraulic system fluid level should be checked
at 25-hour intervals and should be serviced to
levels in accordance with the installed placard
using MIL-H-5606 (red) hydraulic fluid. The
fluid level placard (Figure 1-5) is installed on
the forward hydraulic Reservoir.

PLACARD
The nose wheels are fully castoring for
maneuverability while the airplane is under
engine power or being towed.
The main landing gear has dual 6:00x6 8-ply
tires and the nose gear has a single 5:00x5 10-
ply tire. All tires must be approved to TSO
C62, type III. Differential use of the main-
wheel brakes steers the aircraft on land.
