WIPLINE MODEL 2100/2350 SERVICE MANUAL
1002549 • Rev F Page 9
1.0 GENERAL
The model 2100/2350 seaplane or amphibious float is an all aluminum-constructed float
with watertight compartments. The actual displacement in fresh water for each float is 2323
pounds (model 2100) and 2570 pounds (model 2350) buoyancy for the seaplane and 2185
pounds (model 2100) and 2432 pounds (model 2350) buoyancy for the amphibian. The
amphibian float 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 a 5.00 x 5 6-ply tire and the nose landing gear has a 2.50 x 4
4-ply tire. The gear system is hydraulically actuated and driven by one reversible electric
pump. Brakes are hydraulic and have a caliper on each main wheel.
Steering on land is accomplished by differential braking. The nose wheels are full
castering.
Access to the float interior is accomplished by removing covers on the top deck, side skins
and two covers inside the wheel well. When necessary, water inside the float hulls may be
removed through pumpout cups located on the outboard edge of each float top skin.

2.0 FLOAT HULL MAINTENANCE
2.1 GENERAL
The float structure side and top skins are 6061-T6 and forward and aft bottom skins
are 2024-T3 aluminum sheet and 6061-T6 extrusions. Skins are alodined and primed after
being cleaned and acid-etched. Exterior is finished with an enamel color paint, or
equivalent.
2.2 CLEANING
The outside of the float should be kept clean by washing with soap and water, with
special care taken to remove engine exhaust trails, water line marks, and barnacle deposits
as these are all linked to corrosion. After saltwater operation, washing with fresh water
should be done daily with special attention to hard-to-reach places, such as seams, wheel
well, etc. The float interior should be flushed if salt water enters the compartments; it’s
easy to tell by the smell inside the float lockers. At night or when the floatplane is in
storage, the inspection and/or baggage covers should be opened so the interior has a
chance to dry out. THE ABOVE CLEANING TECHNIQUES ARE VITAL
FOR KEEPING CORROSION TO A MINIMUM. SALTWATER
OPERATIONS ARE STRONGLY LINKED TO
CORROSION AND MUST BE ADDRESSED PROACTIVELY.
2.1 Hard Landing and Damage Investigation
After a thorough cleaning of the damaged area, all structural parts should be carefully
examined to determine the extent of damage. Frequently, the force causing the initial damage
is transmitted from one member to the next, causing strains and distortions. Abnormal stresses
incurred by shock or impact forces on a rib, bulkhead, or similar structure, may be transmitted to
the extremity of the structural member, resulting in secondary damage, such as sheared or
stretched rivets, elongated bolt holes, or canned skins or bulkheads. Points of attachment
should be examined carefully for distortion and security of fastenings in the primary and
secondary damaged areas at locations beyond the local damage.
