WIPLINE 2100 & 2350 FLOATS

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.
2.3 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.
