ABSTRACT:
A method for restoring and maintaining buoyancy for floatplane floats by inserting an inflatable air bag into the leaking compartment in the float and inflating the air bag until the water in the float is expelled from the float and the air bag seals the leak. A puncture resistant air bag also may be permanently installed in a floatplane float at the time of manufacture in order to prevent leaks.
