Aviator with pilot's case arranged to see singer (9)
I believe the answer is:
pavarotti
'singer' is the definition.
(I know that Pavarotti is a tenor)
'aviator with pilot's case arranged' is the wordplay.
'with' is a charade indicator (letters next to each other).
'case' suggests removing the centre.
'arranged' indicates anagramming the letters (letters rearranged).
'pilot' with its centre removed is 'pt'.
'aviator' after 'pt' is 'ptaviator'.
'ptaviator' anagrammed gives 'PAVAROTTI'.
'to see' is the link.
(Other definitions for pavarotti that I've seen before include "Operatic tenor, d.2007" , "Luciano . . . . . . . . ., great Italian tenor" , "Luciano ......... popular modern Italian tenor." , "Air ace" , "Singer" .)
