Amelia —, first woman to fly solo non-stop across the Atlantic (7)
I believe the answer is:
earhart
(Other definitions for earhart that I've seen before include "Amelia --, air pioneer" , "high-flier" , "Amelia __ , aviator, d. 1937" , "Amelia ....... was American flying pioneer" , "Amelia ....... was pioneering American aviator" .)
