Pilot gave Tina bananas (8)
I believe the answer is:
navigate
'pilot' is the definition.
(I know that pilot can be written as navigate)
'gave tina bananas' is the wordplay.
'bananas' indicates anagramming the letters (informal term for mad).
'gave'+'tina'='gavetina'
'gavetina' is an anagram of 'NAVIGATE'.
(Other definitions for navigate that I've seen before include "Drive" , "Move around while browsing the Internet" , "Plan ship's course" , "Guide ship or aircraft" , "Plan and follow a route" .)
