Analysis

The pilot tried three times to take off and aborted each attempt due to rough sea. He then noticed the left float was sinking due to several missing bilge plugs. After shutting down the engine, he attempted to pump out the float and plug the holes with wadded paper. When the airplane began to list, he told his passengers to don life vests. The passengers exited the airplane and tried to stop water seepage into the right float. When they looked around for the pilot, he had disappeared. He was last seen holding onto his life vest and treading water. He is presumed drowned. His inflated life vest was recovered. The passengers were rescued by a passing ship.
