From all accounts and links, I have not found a name for her airplane. Amelia Earhart bought a Lockheed 10E Electra forher attempt to fly around the world in 1937. Her aircraft was lost in the Pacific Ocean and some people suspect the Japanese military did not want her spying on their business just before the start of WW2.
I know what you are thinking. I've seen the commercial where they have a crashed airplane with "Amelia Earhart" painted on the nose. Here is a link to a photo of her plane and there is no name painted on the nose.
UPDATE (09.16.2008)
Although there was no special name or nickname painted somewhere on the plane itself, Amelia Earhart herself frequently called it the "Flying Laboratory"
