He flew too near to the sun (6)
I believe the answer is:
icarus
(Other definitions for icarus that I've seen before include "In Greek myth, he flew too close to the sun and died" , "Mythological figure who died when the sun melted the wax on his wings" , "one on hazardous trip" , "His false wings melted" , "His wings melted when he flew too near the sun" .)
