Craze to which the airman possibly has no right! (5)
I believe the answer is:
'craze' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for mania that I've seen before include "fixation" , "Frenzy" , "Obsessive enthusiasm" , "Passion -- mood disorder" , "wildness" .)
