1.0 GENERAL
The model 4000 seaplane or amphibious oat is an all aluminum constructed oat with watertight compartments.
The actual displacement in fresh water for each oat is 3802 pounds buoyancy for the seaplane and 3672 pounds
buoyancy for the amphibian. The amphibian oat is geometrically the same as the seaplane except for the
addition of landing gear and internal structure for the gear.
The water rudder system is cable operated with ball bearing pulleys. Water rudder cables tie into the existing
aircraft rudder system.
The main landing gear has dual 5.00 x 5 6-ply tires and the nose landing gear has one 4.10 x 4 4-ply tire. The
gear system is hydraulically actuated and driven by one pump located on the engine rewall on a Cessna 185 and
in the aft fuselage at Sta. 159.3 on a Cessna 206. Brakes are hydraulic and have a caliper on each main wheel
for a total of four brakes.
Steering on land is accomplished by di󰀨erential braking. The nose wheels are full castering.
Access to the oat interior is accomplished by removing covers on the top deck and four covers inside the
wheel well. When necessary, water inside the oat hulls may be removed through pump out cups located on the
outboard edge of each oat top skin.
